We are in the “Wild West” still, and believe that we must solve this problem in order to move the space forward. Ethos aims to create a more trusted environment, increase participation in the crypto economy, and "modernize" crypto society. Modern society runs on credibility. Outside of crypto, one gets a job with a resume, checks reviews to choose a doctor, or gets matched with a 5-star Uber driver. Easily referenced, legible credibility is missing in crypto and Ethos fills that gap. Ethos provides a credibility score with a backing profile, akin to a credit report but with open protocols and onchain records. Ethos incentivizes ethical behavior via social Proof of Stake; a decentralized consensus-based validation mechanism driven by human values, judgement, and actions. ### [](https://whitepaper.ethos.network/#a-new-credibility-platform) A New Credibility Platform A credibility platform provides this capability without locking users into a single experience. A platform becomes part of the entire crypto infrastructure, not limited to one distributed app (dApp). The intent is that existing interfaces (Chrome plugins, Metamask snaps) and dApps may integrate and build on top of a shared foundation that we refer to as the Ethos "protocol." ### [](https://whitepaper.ethos.network/#mechanisms) Mechanisms By adapting consensus mechanisms Ethereum relies on today, Ethos can help solve the problem of “social validation” - what does it mean to be reputable? What does it mean to be trusted? Who is reputable and trusted, and how much? The Ethos protocol provides the following set of interlocking mechanisms. Together these form a common platform, incentivize ethical behavior, and generate a credibility score. ### [](https://whitepaper.ethos.network/#review) [Review](https://whitepaper.ethos.network/ethos-mechanisms/review) Ethos provides the standard rate and comment interface. Reviews provide the ability to develop a reputation outside of financially backed stakes. ### [](https://whitepaper.ethos.network/#vouch) [Vouch](https://whitepaper.ethos.network/ethos-mechanisms/vouch) Participants may vouch their Ethereum (or in the future, other assets) in other people. This is the highest credibility signal on Ethos and is closest to traditional staking in Proof of Stake systems. ### [](https://whitepaper.ethos.network/#slash) [Slash](https://whitepaper.ethos.network/ethos-mechanisms/slash) If a validator acts in bad faith, anyone who vouches them is able to pledge ETH to propose a slashing. If "validators" confirm unethical actions, slashing removes a percentage of staked ETH from the offender's value locked in the Ethos contract. Rejected slashings will penalize the proposer by redistributing their pledged ETH instead. ### [](https://whitepaper.ethos.network/#invite) [Invite](https://whitepaper.ethos.network/ethos-mechanisms/invite) Users must first be invited by an existing Ethos profile before participating in Ethos. Invitations are not automatically added to a user's profile, and are inherently limited. Invitations create credibility score bonds between inviters and invitees, discouraging users from inviting bad actors or themselves. This helps Ethos maintain a sybil resistant network. ### [](https://whitepaper.ethos.network/#attest) [Attest](https://whitepaper.ethos.network/ethos-mechanisms/attest) To reflect authority, reputation, and influence from other sources, one may attest other social network profiles to connect them a single Ethos profile. ### [](https://whitepaper.ethos.network/#credibility-score) [Credibility Score](https://whitepaper.ethos.network/ethos-mechanisms/credibility-score) By interpreting social interactions generated by the above mechanics, Ethos generates a single numerical credibility score. ### [](https://whitepaper.ethos.network/#ethos-profile) [Ethos Profile](https://whitepaper.ethos.network/ethos-mechanisms/profile) The profile highlights the credibility score and provides corroborating details. From the profile you can ascertain allies and enemies, praise and gaffes, kept and broken promises, etc. ### [](https://whitepaper.ethos.network/#governance) [Governance](https://whitepaper.ethos.network/governance/principles) As credibility is too powerful to leave in the hands of centralized influence, Ethos Labs will transition control of the scoring algorithm to participants. ### [](https://whitepaper.ethos.network/#impact) Impact We believe that the crypto economy thrives when everyone can readily ascertain each other's credibility. A score comprised of a reputation of vouches, reviews, and connections should be sufficient to form a qualified understanding of social signals. This way Ethos helps everyone evaluate their trust with everyone they are working with or talking to, without breaking pseudonymity. Ultimately the entire space will mature when everyone will expect a meaningful amount of credibility to fund a new project, have a trusted voice, or exchange goods for tokens.

We all prosper when we can exchange goods and services reliably. Unethical behavior is a drain on markets, increasing risk, reducing participation, and making us all poorer in the end. With Ethos, opportunities will flow towards those with a long standing ethical history. Scammers, grifters, and the unethical will find it expensive, risky, and time consuming to fake these signals. Ethos increases investment in the ethical and increases expenses for the unethical. ### [](https://whitepaper.ethos.network/about-ethos/ethos-labs#mission-crypto-participation-requires-credibility) Mission: crypto participation requires credibility > Trust is essential for society to function—our civilization would collapse completely without it—and the fact that we don’t think about it is a measure of how well that trust works. > > \-- Bruce Schneier, [Trust and Society](https://www.schneier.com/essays/archives/2013/02/trust_and_society.html) Everyone wins when checking credibility is universal. A lack of credibility evidence will be suspicious. It should be so easy, so commonplace to build and maintain a reputation on chain that there will be no excuse not to do so. When it's so automatic that we barely think about it, the crypto market will mature to the point where scams are rare and obvious. In the not-so distant future, we assume nobody will take you seriously until you have an Ethos profile. ### [](https://whitepaper.ethos.network/about-ethos/ethos-labs#goals) Goals Goal Measurement Align financial incentives to be backed by credibility, not rewarded by grift Coins, funds, and projects leveraging Ethos raise above-average investment Raise the bar of what credibility means in web3 % of top crypto influencers maintaining Ethos profiles Increase overall crypto adoption by making it a safer place for new participants % of new crypto participants connecting to Ethos Save crypto billions in scams and rug pulls Ethos participants exposed as grifters permanently lose credibility Lead by example to demonstrate the power of ethical behavior Phase governance from central control, to points, to decentralized governance. Last updated 1 year ago --- # Why Ethos | Ethos [](https://whitepaper.ethos.network/about-ethos/why-ethos#you-are-your-actions) “You are your actions” ----------------------------------------------------------------------------------------------------------- The web3 and crypto space suffers because people are detached from their long term reputation. We aim to provide that link without sacrificing the benefits of pseudonymity. It’s time for people to put their reputation on the line. In the not-so distant future, we assume other participants will take you seriously until you have an Ethos profile. Don’t take our word for it (establishing credibility is the whole point here). Ask yourself these questions: 1. If you come across a new coin, protocol, or dApp - how legit do you assume it is? 2. How would you currently try to assess if it’s real? How does that compare to web2 or tradfi? 3. If there was a web3 crypto-native equivalent, what would it need to look like? We believe: 1. Crypto and web3 are in the “Wild West” phase. Trust is low. Having morals is expensive. Scams abound. Reputation is easily thrown away in favor of profits. 2. We currently try to estimate credibility on imperfect indicators, like Twitter followers, wallet holdings, and transaction history. Compare this to TradFi with credit reports and Consumer Reports; or web2 with TrustPilot, Yelp, etc. 3. If you could check a credibility profile for people you interact with, you could avoid expensive mistakes and determine, even increase, trustworthiness for every single person you meet online. These answers shape a potential solution in the following ways: #### [](https://whitepaper.ethos.network/about-ethos/why-ethos#a-legible-record) A legible record An “at a glance” profile must summarize the most impactful events from a growing history of online behavior. In order to collect that record, incentives drive participants to review and vouch for other’s positive actions. Whistleblowers' accusations are verified by a trusted community. In Ethos, a credibility score represents all this succinctly. #### [](https://whitepaper.ethos.network/about-ethos/why-ethos#an-independent-profile) An independent profile In order for anyone to check a profile, it must be independent of any social network, app, protocol, or owner. It must exist as a foundational layer that other apps can reference. For this reason Ethos is an independent, decentralized platform that provides APIs to apps and sites. #### [](https://whitepaper.ethos.network/about-ethos/why-ethos#inviting-to-everyone) Inviting to everyone Everyone should be able to join, and thrive, by using Ethos while they are building their reputation and wealth. Joining Ethos should accelerate both those pursuits. Ethos rewards participation regardless of funds, and funds cannot be used to “pay to win.” #### [](https://whitepaper.ethos.network/about-ethos/why-ethos#skin-in-the-game) Skin in the game Durable long-term credibility requires balancing financial and social incentives. Ethos is designed so that a great reputation encourages investment; earnest rewards from investment build a great reputation. #### [](https://whitepaper.ethos.network/about-ethos/why-ethos#trustworthy) Trustworthy To sustain long term fairness, Ethos itself intends to avoid centralized ownership. Decentralized governance is planned as part of the protocol design and corporate structure. The creators have not taken on venture capital to limit outsized control of token distribution. Early angel investors had a strict maximum equity offering. Last updated 7 months ago --- # Slash | Ethos **Slashing** fines unethical behavior. Slashing is not currently live in the Ethos. It will be added at a later date. The exact parameters of how Slashing works are subject to change before launch. ### [](https://whitepaper.ethos.network/ethos-mechanisms/slash#social-validation) Social Validation In the Ethereum Proof of Stake consensus protocol ([Beacon Chain](https://ethereum.org/en/roadmap/beacon-chain/) ), with sufficient staked Ethereum (currently 32Ξ), one may act as a validator. Validators verify the accuracy and security of transactions and receive rewards for their efforts. Validators may act as a "[whistleblower](https://www.blocknative.com/blog/an-ethereum-stakers-guide-to-slashing-other-penalties) " and highlight an inaccurate or insecure transaction for extra validation, with various rewards and fees. ### [](https://whitepaper.ethos.network/ethos-mechanisms/slash#slashing-financial) Slashing - Financial Any Ethos participant may act as a "whistleblower" to accuse another participant of inaccurate claims or unethical behavior. This accusation triggers a 24h lock on staking (and withdrawals) for the accused. The whistleblower requests human validation by pledging a nominal reward to validators. Validators vote to indicate if they found the claims valid. Validators are rewarded the same whichever way they vote. If validators vote in favor of the whistleblower, they reward the whistleblower pledged to validators is reimbursed _from the amount staked by the accused._ This is the "slashing punishment," and it cannot exceed 10% of the total amount staked in Ethos (as of writing) **This is the** _**only**_ **way in which staked funds may be withdrawn without the explicit approval of the person staking those assets.** It is intended to be rare; most unethical behavior can be reported first by a negative review or unvouching. Upon being slashed the accused has a 72h grace period before they may be slashed again. ### [](https://whitepaper.ethos.network/ethos-mechanisms/slash#slashing-social) Slashing - Social Ethos users can also create "Social Slashings" where instead of actual capital risked, they risk their own social capital in the form of their credibility score. The slashing follows a similar process of voting and validation for their claim. Last updated 4 months ago --- # Review | Ethos Reviews convey credibility opinions succinctly. ### [](https://whitepaper.ethos.network/ethos-mechanisms/review#rate-and-comment) Rate and comment Ethos reviews follow a negative, neutral and positive rating standard. Because it's so universal, it's easy to embed in any context without confusing anyone. It's second nature. It also provides both quantitative and qualitative feedback. ### [](https://whitepaper.ethos.network/ethos-mechanisms/review#sybil-who) Sybil Who? Ethos requires that you have a valid Ethos profile (and thus invitation to Ethos) before one can leave reviews. This has the benefit of reducing spam and sybil attacks. Reviews are not anonymous; they include who left the review. ### [](https://whitepaper.ethos.network/ethos-mechanisms/review#impact-on-credibility) Impact on Credibility Reviews influence the credibility score. The extent to which they adjust the score depends on the credibility consensus. A few of the ways reviews have impact include: * High credibility reviewers will have more impact, per-review * Reviews may be normalized per reviewer; someone who only leaves positive reviews may have less impact. Same for someone only leaves negative reviews * The age and volume of reviews * Reviewers vouching you, or vouched by you, have more impact This will be thoroughly documented and transparent through our [Credibility Score](https://whitepaper.ethos.network/ethos-mechanisms/credibility-score) . ### [](https://whitepaper.ethos.network/ethos-mechanisms/review#philosophy) Philosophy Reviews are fast and free. Thus they are a weaker but earlier signal. They may be a fluke or provide an early warning sign. Reviews provide a lightweight way to provide feedback, even publicly denounce someone, before progressing to actions with financial stakes such as vouching, unvouching or slashing. One should be able to earn a reputation before one has substantial funds or a large network. Reviews facilitate that. ### [](https://whitepaper.ethos.network/ethos-mechanisms/review#under-the-hood) Under the hood The review interface is intentionally simple and adaptable. Apps can add tags, keys, or text for capabilities customized for specific markets or audiences. Stay tuned for additional details on how you can integrate reviews into your own product. [](https://whitepaper.ethos.network/ethos-mechanisms/review#future-opportunity) Future opportunity ------------------------------------------------------------------------------------------------------- Opinions and true feelings are often lost to fear of social repercussions. Ethos reviews today are onchain and require a profile, so everyone can see exactly how people perceive each other. If the highest social signals we can get are from _anonymous_ opinions, how can we leverage the Ethos credibility score to qualify those? We intend to eventually enable zkProofs for reviews, allowing people to anonymously review people with the qualifier of "Credibility score range," enabling reviews such as "A highly credible person has negatively reviewed Bob" Without the credibility score calculation, anonymous reviews lack any qualification to appropriately separate noise (spam from unreputable people) from signal. Last updated 7 months ago --- # Attest | Ethos **Attestation** ensures people are who they say they are. In Ethos you attest by recording onchain the other ways you represent yourself (and your reputation) online. This can include digital identities, profiles, and wallets. Attestation is vital to prevent fraud and impersonation. ### [](https://whitepaper.ethos.network/ethos-mechanisms/attest#price-and-costs) Price and Costs Attestation is free; the price is nothing more than the required gas fees. Lying about your identity, however, is the most expensive action you can take on Ethos. Fraudulent attestation warrants Social Validation and Slashing (see: [Vouch](https://whitepaper.ethos.network/ethos-mechanisms/vouch) ), which costs both reputation and staked Ethereum. ### [](https://whitepaper.ethos.network/ethos-mechanisms/attest#mutually-exclusive) Mutually Exclusive No two Ethos Profiles can attest the same account or wallet. If one of your external accounts are already linked to another Ethos Profile, you may reclaim it automatically, without intervention or social validation. This action will be reflected as evidence on chain, which you can then use to "blow the whistle" on the fraudulent Ethos Profile pretending to be you, and trigger Social Validation. ### [](https://whitepaper.ethos.network/ethos-mechanisms/attest#account-verification) Account Verification Attesting external accounts requires demonstrating you have control over that account. Typically this requires emitting a message (tweet, post, etc) or updating a page (profile, commit) from that external account. This does mean that _group accounts_ (like a business's Facebook profile) for which multiple people have access may be easy to accidentally attest from the wrong Ethos profile. Support for various external accounts (Twitter, Facebook, Github, etc) will be added individually; this is not a blanket mechanism for attesting any link. ### [](https://whitepaper.ethos.network/ethos-mechanisms/attest#wallet-verification) Wallet Verification Attesting a wallet requires signing a request. Most wallet providers make this easy, as this is a standard Ethereum specification ([EIP-712](https://eips.ethereum.org/EIPS/eip-712) ). Ethos plans to support wallets for blockchains beyond Ethereum. An Ethos profile can attest multiple wallets. This allows one to maintain security by keeping assets in different wallets with different keys, yet still represent all the assets within one Ethos profile. Any multi-sig wallets will require sufficient signing keys to sign the Ethos profile request, by definition. Ethos supports custodial and non-custodial wallets. Ethos can support hardware or air-gapped wallets, though you'll need to know how to hash and sign requests specific to each type of these offline wallets. ### [](https://whitepaper.ethos.network/ethos-mechanisms/attest#pseudonymity-and-permanence) Pseudonymity and Permanence There is no requirement that attestation includes real names or identities. Real names do not confer any advantages to the [Credibility Score](https://whitepaper.ethos.network/ethos-mechanisms/credibility-score) calculation. Attested accounts and wallets are recorded permanently on chain. Be careful. If you maintain separate identifies for operational security or privacy reasons, one slip up is enough to permanently "burn" that pseudonym. ### [](https://whitepaper.ethos.network/ethos-mechanisms/attest#proof-of-humanity) Proof of Humanity Ethos explicitly does not require [Proof of Humanity](https://worldcoin.org/blog/worldcoin/proof-of-personhood-what-it-is-why-its-needed) . Brands, clubs, governments, bots, AI, and any other sentient creatures are able to develop and maintain a reputation, independent of their biological underpinnings. ### [](https://whitepaper.ethos.network/ethos-mechanisms/attest#philosophy) **Philosophy** Reputation stems from communities. A profile on LinkedIn, Tinder, and Reddit will have very different connotations. Ethos should augment, not compete with, social apps like these. Reputation is multifaceted. The same person may have distinct reputations in multiple communities. Public information can still be privacy-sensitive; even if both Tinder and LinkedIn use your real name, few people want them intertwined. Reputation is also much more than identity. Pseudonymity provides benefits towards innovation the same way limited liability corporations do; by not putting "everything on the line," we promote experimentation and risk-taking. Ethos promotes the benefits of pseudonymity while also curtailing the drawbacks. ### [](https://whitepaper.ethos.network/ethos-mechanisms/attest#under-the-hood) Under the hood Attestation is an open schema that is designed not to solely depend on Ethos infrastructure or smart contract. For linking accounts, an Ethos Oracle will validate an attestation link in a tweet, post, or profile. It will then send a transaction to the Ethos Smart Contract in an open format, list itself as a validator, and sign it. When linking wallets, anyone may submit a attestation payload to the Ethos Smart Contract signed by the wallet itself. The Ethos Oracle will provide a convenience function to sign and submit that payload using public wallet APIs and services (ex: [Metamask](https://docs.metamask.io/wallet/concepts/signing-methods/) signing). Last updated 1 year ago --- # Invite | Ethos An **invitation** is required to create an Ethos profile. Invitations create a bond between an inviter and the invitee's credibility score for the first 90 days. Invitations help us ensure a sybil resistant network where users risk their own social capital in who they invite. ### [](https://whitepaper.ethos.network/ethos-mechanisms/invite#how-invitations-work) How invitations work An existing user may use the invite function of the Ethos protocol to invite another Ethereum address. Invitations are intended to be limited, and their initial distribution will be managed by the Ethos Labs team. Invitations from credible users increase new user's score significantly. Invitations can be revoked if they have not been accepted yet. ### [](https://whitepaper.ethos.network/ethos-mechanisms/invite#the-invitation-bond) The invitation bond There is a 90 day bonding period when someone accepts your invitation. During this time you will earn 20% of their score, positive OR negative. This is intended to create some both upside and downside in your social capital by being selective in who you invite. If a user invites a bad actor, who's score drops dramatically in the 90 day bonding period, the invitee will lose some of their credibility score as well. This discourages people from inviting bad actors.. or potentially themselves. It encourages people to invite credible, reputable people as they will also earn credibility score from it. Last updated 7 months ago --- # Vouch | Ethos **Vouching** indicates a high degree of trust. In Ethos you vouch by staking Ethereum in an Ethos profile, a wallet address, or a social attestation. This fundamental core mechanism is how Ethos captures a network of trusted relationships. It represents the extent to which you are supported by allies and supporters, and thus strongly impacts credibility. ### [](https://whitepaper.ethos.network/ethos-mechanisms/vouch#financial-stakes) Financial Stakes Vouching, unlike [Review](https://whitepaper.ethos.network/ethos-mechanisms/review) , requires a backing asset: staked Ethereum (and in the future, other assets). This forces you to choose how you would allocate your trust and in what amounts and ratios. Does your entire network get equal trust, or would you vouch for some more than others? The amount of Ethereum staked represents the magnitude of the trust placed in you. Ethos does not differentiate between one person who vouches you with 100Ξ or 100 people who vouch you with one Ethereum. This has many benefits, including that credibility is not a popularity contest; having a single strong supporter can be more impactful than dozens of weaker ties. However, the person you vouch DOES NOT HAVE DIRECT CONTROL over the backing asset. They cannot withdraw, spend, or re-allocate those staked funds. ### [](https://whitepaper.ethos.network/ethos-mechanisms/vouch#impact-on-credibility-score) Impact on credibility score In the Ethos webapp, credibility score is earned through vouching over time, as opposed to instantaneously. That credibility is currently earned over a 6 month bond. ### [](https://whitepaper.ethos.network/ethos-mechanisms/vouch#mutual-respect) Mutual Respect When you vouch someone and they vouch you back, Ethos notes your mutual stake. This is commonly referred to as a (3,3) relationship. Credibility and rewards for both of you are magnified. However, defecting from a mutual stake represents a greater indication that you might be untrustworthy; why would you turn your back on a friend who vouched for you? ### [](https://whitepaper.ethos.network/ethos-mechanisms/vouch#slashing) Slashing Slashing provides a mechanism by which unethical behavior may be identified, socially validated, and punished via fines and reduced reputation. Slashing can induce penalties of one's total stake in Ethos. Details in [Slash](https://whitepaper.ethos.network/ethos-mechanisms/slash) . ### [](https://whitepaper.ethos.network/ethos-mechanisms/vouch#unvouch) Unvouch You may withdraw your staked funds at any time by unvouching. You cannot modify the amount staked in a vouch without withdrawing the entire vouch. If you are mutually vouched (3,3) and unvouch, the person who was vouched can mark a vouch as "unhealthy" within 24 hours to signal to the network the vouch ended on poor terms. ### [](https://whitepaper.ethos.network/ethos-mechanisms/vouch#philosophy) **Philosophy** A long standing mutually beneficial relationship is the single best indicator of trust. People make mistakes. Penalties should be proportional; not everything is a “completely ruin your reputation” event. However, explicit deceit and defection _for the purposes of financial gain_ should have the potential to prompt strong financial disincentives. In the case where unethical behavior is sufficient to completely destroy one's reputation, all stakers will withdraw their funds and credibility will drop. This is the social equivalent of bankruptcy. Because Ethos is pseudonymous, it is always possible to start a new profile from scratch. Last updated 21 days ago --- # Credibility Score | Ethos **Credibility Scores** quantify credibility indicators. ### [](https://whitepaper.ethos.network/ethos-mechanisms/credibility-score#calculation) Calculation The Credibility Score algorithm will factor in a variety of weighted indicators. Indicators include relevant on chain actions, such as: * number of vouchers, mutual vouches, and amount vouched * mutual vouch duration and defection * credibility score of vouchers or reviewers * average rating of your contributions on Ethos * account ages of attestation Weights do not need to be linear. For example, having 100 positive reviews may provide 2x more credibility than 10 positive reviews. Indicators and weights may be added, removed, or adjusted according to the [Credibility Consensus](https://whitepaper.ethos.network/governance/credibility-consensus) . ### [](https://whitepaper.ethos.network/ethos-mechanisms/credibility-score#range) Range The range of the credibility score is currently 0 to 2800, with 5 different levels 0-799 - untrusted 800 -1199 - questionable 1200 - 1599 - neutral 1600-1999 - reputable 2000- 2800 - exemplary All wallets and attestations start at the default 1200 score, "neutral." ### [](https://whitepaper.ethos.network/ethos-mechanisms/credibility-score#usage) Usage Credibility scores are intended as an "at a glance" quick estimate of credibility across many domains. No single number can represent the complexities of one's reputation among that many groups and interactions. Different communities' needs may warrant additional weights and calculations. Ethos open protocol allows other dApps to define alternate scores using the same on chain records. ### [](https://whitepaper.ethos.network/ethos-mechanisms/credibility-score#under-the-hood) Under the hood The credibility score will be calculated using on chain Ethos protocol data only. The algorithm will be committed to the Ethos Smart Contract, with all details publicly verifiable. Other dApps may surface alternative credit scores. Last updated 1 month ago --- # Profile | Ethos Each **Profile** aggregates credibility evidence. ### [](https://whitepaper.ethos.network/ethos-mechanisms/profile#credibility-hub) Credibility Hub One's Ethos Profile presents a summary of relevant credibility cues. Each cue represents on chain activity from Ethos protocol or linked wallets. It highlights the most high impact Ethos elements, including high stakes vouches, high profile reviews, and major financial holdings. The profile provides a launching off point to answer questions beyond what can be summarized in a single page. Drill down to identify what's most relevant. From the profile you can ascertain their social circles, allies, major praise and gaffes, kept and broken promises, etc. ### [](https://whitepaper.ethos.network/ethos-mechanisms/profile#credibility-score) Credibility Score The Ethos [Credibility Score](https://whitepaper.ethos.network/ethos-mechanisms/credibility-score) attempts to summarize as much relevant financial and reputational elements into a single numerical value. This is similar to a how a credit report includes a [credit score](https://en.wikipedia.org/wiki/Credit_score) . Because this calculation depends on social norms and impacts people's livelihoods, the algorithm itself is determined by the [Credibility Consensus](https://whitepaper.ethos.network/governance/credibility-consensus) . ### [](https://whitepaper.ethos.network/ethos-mechanisms/profile#chain-station) Chain Station The Ethos Profile provides a convenient user experience for vouching, attesting, and leaving reviews. However, the profile itself is stateless; it retrieves data from on chain, and facilitates transactions with the Ethos Smart Contract. The intent is that anyone may offer alternate profiles or applications that retrieve Ethos protocol data. Ethos provides a platform and record of credibility data; there are likely to be many useful ways to interpret it. ### [](https://whitepaper.ethos.network/ethos-mechanisms/profile#philosophy) Philosophy The Ethos vision includes being able to assess credibility for anyone you interact with online. The profile is the most substantial realization of that vision. Ideally other apps may reference elements of the profile contextually, without requiring the user to navigate to the profile page. ### [](https://whitepaper.ethos.network/ethos-mechanisms/profile#under-the-hood) Under the hood The profile is stateless but Ethos off-chain infrastructure retains a cache for prompt page loads. ### [](https://whitepaper.ethos.network/ethos-mechanisms/profile#notes) Notes Profile is intended as a noun, not a verb. Last updated 1 year ago --- # Principles | Ethos ### [](https://whitepaper.ethos.network/governance/principles#you-are-your-actions) Credibility is collective > Society runs on trust. We all need to trust that the random people we interact with will cooperate. ... If too many people steal or too many people don’t pay their taxes, society no longer works. > > \-- Bruce Schneier, [Trust and Society](https://www.schneier.com/essays/archives/2013/02/trust_and_society.html) No one authority can define credibility. It's a balance of personal judgement and group norms. Signs and signals will evolve with our culture. Principle: any credibility score needs to adapt to collective input. ### [](https://whitepaper.ethos.network/governance/principles#algorithms-are-convenient) Algorithms are convenient However, standard credibility assessments provide market efficiencies. Few have time to perform deep due diligence on every transaction. Traditional market (tradfi) institutions like the SEC and credit report bureaus ensure a minimum threshold via licensing, regulation, and monitoring. Meanwhile ratings and reviews allow web2 consumers to "check for themselves" but still rely on centralized systems. Principle: a credibility score needs to be legible and concise. ### [](https://whitepaper.ethos.network/governance/principles#credibility-is-power) Credibility is power High credibility brings financial rewards. Defining credibility in a market grants influence. How that power is used depends on incentives. Market makers (Uber, eBay) benefit from trust in sellers and buyers. Some, like Amazon, extract fees from sellers to hijack credibility via paid reviews and ad-based placement. Others, like Yelp and Glassdoor, repeatedly face accusations of extorting businesses by suggesting paid plans may help dispute low ratings. Principle: avoid centralized incentives to tamper with credibility for profit. ### [](https://whitepaper.ethos.network/governance/principles#algorithms-change-behavior) Algorithms change behavior People will shape their behavior according to what a credibility algorithm rewards. People's livelihood depends on how a centralized algorithm ranks their credibility. When these algorithms are centralized and owned by organizations, obtuse changes can alter careers and fortunes. For example, YouTubers are in a constant cat-and-mouse game reverse engineering the monetization algorithms. Principle: one must have the ability to influence an algorithm that impacts their livelihood. ### [](https://whitepaper.ethos.network/governance/principles#algorithms-will-be-abused) Algorithms will be abused > "the optimal amount of fraud is greater than zero." > > \-- Patrick McKenzie, [Bits about Money](https://www.bitsaboutmoney.com/archive/optimal-amount-of-fraud/) Any summary will omit details, so credibility scores can't fully represent the truth. This wiggle room allows abusers to optimize to the point where it defeats the original purpose. Centralized management historically fails; there is no way to perfect the algorithm or police all fraud. Instead, rely on the people most impacted to define the trade-offs between usefulness and abuse. Principle: collective governance will ensure a credibility score reflects effective trade-offs between usefulness and abuse.

A market is intended to be attached to an identity that users want to speculate on the reputation for; it could be an individual user, a company or corporation, a DAO, or even an autonomous entity. The amount of markets available will start limited and controlled by Ethos Labs as a means of focusing liquidity into specific markets and giving all users the best possible experience. #### [](https://whitepaper.ethos.network/ethos.markets/litepaper#trust-percentages) Trust percentages Every market has a current Trust/Distrust score based on the current price of trust and distrust votes. This is intended to act as a proxy for how trusted or distrusted someone or something is. At the start, the market starts at 50:50. Buying trust votes increases the price of trust votes and the overall score. This also lowers the price of distrust votes to provide equilibrium to the market. **A pragmatic example might be:** You see someone highly credible like Vitalik at a trust score of 35%. You believe Vitalik is more trustworthy than 35%, so you buy trust votes because you believe his current market price does not correctly reflect his trustworthiness. You believe you can net a profit because his trust score will go up once the "trust market price" has been realized. It's important to understand that these markets are **perpetual**, and do not resolve. This because trust can never truly be resolved at a point in time However, you can imagine derivatives markets that could exist in the future resolve at certain points in time, ie. Vitalik will be above 80% before the end of 2025. ### [](https://whitepaper.ethos.network/ethos.markets/litepaper#implementation-and-liquidity) Implementation & liquidity Ethos Reputation Markets execute on an Automated Market Maker (AMM) smart contract, using a standard Logarithmic Market Scoring Rule (LMSR) algorithm to price two opposite positions. This is the same pricing algorithm used by Polymarket. As an automated market liquidity is managed algorithmically rather than via traditional bid/ask spreads. Ethos Reputation Markets used a fixed liquidity control per market. These markets will continue to 'swing' with the same amount of volume, no matter how many total assets are locked. This has the following benefits: * You are never "too late to the party." Your votes have the same impact as the first market participants. * Markets respond quickly to changing sentiment. It does not require those with the largest holdings to shift positions before the market adapts. * Nobody is required to add liquidity. There's no liquidity crunch as people exit the market. Despite offering a built in "short-like" position, these contracts cannot be short squeezed. For future upgrades, the Reputation Market contract implements a graduate function that allows adoption of future algorithms and implementations, with agreement from the market owner. Note that because Reputation Markets are not prediction markets and do not resolve, they are not "binary options" but lack a formal economic definition; then nearest would be a "binary perpetual." ### [](https://whitepaper.ethos.network/ethos.markets/litepaper#contrasts-to-ethos.network) Contrasts to Ethos.Network Ethos.network and Ethos.markets work as independent but complementary products. The vast majority of people will have Ethos.network accounts but not a market on Ethos.markets. This is due to some constraints around Ethos.market's reputation market design: * There is not enough liquidity in the world to support every user having their own Ethos market. * Ethos.markets ONLY lets people speculate with money, and lacks other social signals like free reviews. * A reputation market has pure financial upside and downside, and could muddy & conflate social signals of "I don't want to lose money" with "I don't trust this person" - something that's much more clear on Ethos.network [](https://whitepaper.ethos.network/ethos.markets/litepaper#acknowledgements-and-contributors) Acknowledgements & Contributors ----------------------------------------------------------------------------------------------------------------------------------- This concept was originally from a conversation we had with [@CL207](https://x.com/CL207) , originally in late 2023 and then again in September 2024.

During the Early Access period of Ethos, the way to interact with the credibility score is using Contributor XP, which are distributed network contributions to Ethos. This empowers and encourages the primary users of Ethos to be the ones who determine how credibility is measured through our in-house Credibility Score. Measuring credibility will be inherently difficult, and everyone will have their own differing opinion on how to weight what goes into calculating that credibility. It's important to understand that during the Early Access period, the goal is to push Ethos' credibility model forward _collectively,_ through _consensus._ The initial scoring model is likely to overvalue some parameters, undervalue others, and completely miss parameters the team hasn't yet thought of. The Early Access period allows us to collectively define that as a community and make sure we optimize the scoring system before Ethos progresses to general availability. With this in mind, during the Early Access period we have two mechanism that will be introduced to govern the credibility score via consensus: ### [](https://whitepaper.ethos.network/governance/credibility-consensus#weekly-votes) Weekly Votes Weekly voting is not currently live in the Ethos Network. It will be added at a later date. Every week, Ethos participants will have the opportunity to vote on two things. * This week's current proposal * Which proposal should be voted on next week. Ethos participants will use their points that they are allocated for network activity each week to vote on each of these. A proposal has 3 options - agree, disagree, or abstain and requires 51% approval from voters to be ratified. The leading proposal at the end of the weekly epoch that was voted on will then be put up for vote the following week. Ethos participants will have to choose whether they want to allocate their points to current proposal outcomes vs the ability to vote and participate on future proposals. Upon the outcome of the current week's proposal, the credibility algorithm will be modified accordingly. In the Early Access phase, this will be done in a centralized manner by the Ethos team, who will manually make the tweaks. This enables full extensibility of the model so that we can introduce new ways to measure credibility as we work together to get the algorithm to true consensus. ### [](https://whitepaper.ethos.network/governance/credibility-consensus#vote-proposals) Vote Proposals Every week during the Early Access period, the Ethos team will author 3 vote proposals for how to modify the current credibility score. Ethos network participants will also be able to create their own vote proposals, which will last over the period of 3 weekly epochs before disappearing. Proposals must have clear definition to the modification of the algorithm, as an example: * Weight "number of vouchers" by 10% less * Change the algorithm for "defection score" from nlog(n) to n! * Introduce a new measurement, the value of vouchers that are 1 hop away and weight them along a specified algorithm Points used to vote for proposals are reset at the end of the weekly epoch and must be recast. The top proposal is then voted on the next week.

We are in the “Wild West” still, and believe that we must solve this problem in order to move the space forward. Ethos aims to create a more trusted environment, increase participation in the crypto economy, and "modernize" crypto society. Modern society runs on credibility. Outside of crypto, one gets a job with a resume, checks reviews to choose a doctor, or gets matched with a 5-star Uber driver. Easily referenced, legible credibility is missing in crypto and Ethos fills that gap. Ethos provides a credibility score with a backing profile, akin to a credit report but with open protocols and onchain records. Ethos incentivizes ethical behavior via social Proof of Stake; a decentralized consensus-based validation mechanism driven by human values, judgement, and actions. ### [](https://whitepaper.ethos.network/about-ethos#a-new-credibility-platform) A New Credibility Platform A credibility platform provides this capability without locking users into a single experience. A platform becomes part of the entire crypto infrastructure, not limited to one distributed app (dApp). The intent is that existing interfaces (Chrome plugins, Metamask snaps) and dApps may integrate and build on top of a shared foundation that we refer to as the Ethos "protocol." ### [](https://whitepaper.ethos.network/about-ethos#mechanisms) Mechanisms By adapting consensus mechanisms Ethereum relies on today, Ethos can help solve the problem of “social validation” - what does it mean to be reputable? What does it mean to be trusted? Who is reputable and trusted, and how much? The Ethos protocol provides the following set of interlocking mechanisms. Together these form a common platform, incentivize ethical behavior, and generate a credibility score. ### [](https://whitepaper.ethos.network/about-ethos#review) [Review](https://whitepaper.ethos.network/ethos-mechanisms/review) Ethos provides the standard rate and comment interface. Reviews provide the ability to develop a reputation outside of financially backed stakes. ### [](https://whitepaper.ethos.network/about-ethos#vouch) [Vouch](https://whitepaper.ethos.network/ethos-mechanisms/vouch) Participants may vouch their Ethereum (or in the future, other assets) in other people. This is the highest credibility signal on Ethos and is closest to traditional staking in Proof of Stake systems. ### [](https://whitepaper.ethos.network/about-ethos#slash) [Slash](https://whitepaper.ethos.network/ethos-mechanisms/slash) If a validator acts in bad faith, anyone who vouches them is able to pledge ETH to propose a slashing. If "validators" confirm unethical actions, slashing removes a percentage of staked ETH from the offender's value locked in the Ethos contract. Rejected slashings will penalize the proposer by redistributing their pledged ETH instead. ### [](https://whitepaper.ethos.network/about-ethos#invite) [Invite](https://whitepaper.ethos.network/ethos-mechanisms/invite) Users must first be invited by an existing Ethos profile before participating in Ethos. Invitations are not automatically added to a user's profile, and are inherently limited. Invitations create credibility score bonds between inviters and invitees, discouraging users from inviting bad actors or themselves. This helps Ethos maintain a sybil resistant network. ### [](https://whitepaper.ethos.network/about-ethos#attest) [Attest](https://whitepaper.ethos.network/ethos-mechanisms/attest) To reflect authority, reputation, and influence from other sources, one may attest other social network profiles to connect them a single Ethos profile. ### [](https://whitepaper.ethos.network/about-ethos#credibility-score) [Credibility Score](https://whitepaper.ethos.network/ethos-mechanisms/credibility-score) By interpreting social interactions generated by the above mechanics, Ethos generates a single numerical credibility score. ### [](https://whitepaper.ethos.network/about-ethos#ethos-profile) [Ethos Profile](https://whitepaper.ethos.network/ethos-mechanisms/profile) The profile highlights the credibility score and provides corroborating details. From the profile you can ascertain allies and enemies, praise and gaffes, kept and broken promises, etc. ### [](https://whitepaper.ethos.network/about-ethos#governance) [Governance](https://whitepaper.ethos.network/governance/principles) As credibility is too powerful to leave in the hands of centralized influence, Ethos Labs will transition control of the scoring algorithm to participants. ### [](https://whitepaper.ethos.network/about-ethos#impact) Impact We believe that the crypto economy thrives when everyone can readily ascertain each other's credibility. A score comprised of a reputation of vouches, reviews, and connections should be sufficient to form a qualified understanding of social signals. This way Ethos helps everyone evaluate their trust with everyone they are working with or talking to, without breaking pseudonymity. Ultimately the entire space will mature when everyone will expect a meaningful amount of credibility to fund a new project, have a trusted voice, or exchange goods for tokens.

AcceptReject --- # Review | Ethos Reviews convey credibility opinions succinctly. ### [](https://whitepaper.ethos.network/ethos-mechanisms#rate-and-comment) Rate and comment Ethos reviews follow a negative, neutral and positive rating standard. Because it's so universal, it's easy to embed in any context without confusing anyone. It's second nature. It also provides both quantitative and qualitative feedback. ### [](https://whitepaper.ethos.network/ethos-mechanisms#sybil-who) Sybil Who? Ethos requires that you have a valid Ethos profile (and thus invitation to Ethos) before one can leave reviews. This has the benefit of reducing spam and sybil attacks. Reviews are not anonymous; they include who left the review. ### [](https://whitepaper.ethos.network/ethos-mechanisms#impact-on-credibility) Impact on Credibility Reviews influence the credibility score. The extent to which they adjust the score depends on the credibility consensus. A few of the ways reviews have impact include: * High credibility reviewers will have more impact, per-review * Reviews may be normalized per reviewer; someone who only leaves positive reviews may have less impact. Same for someone only leaves negative reviews * The age and volume of reviews * Reviewers vouching you, or vouched by you, have more impact This will be thoroughly documented and transparent through our [Credibility Score](https://whitepaper.ethos.network/ethos-mechanisms/credibility-score) . ### [](https://whitepaper.ethos.network/ethos-mechanisms#philosophy) Philosophy Reviews are fast and free. Thus they are a weaker but earlier signal. They may be a fluke or provide an early warning sign. Reviews provide a lightweight way to provide feedback, even publicly denounce someone, before progressing to actions with financial stakes such as vouching, unvouching or slashing. One should be able to earn a reputation before one has substantial funds or a large network. Reviews facilitate that. ### [](https://whitepaper.ethos.network/ethos-mechanisms#under-the-hood) Under the hood The review interface is intentionally simple and adaptable. Apps can add tags, keys, or text for capabilities customized for specific markets or audiences. Stay tuned for additional details on how you can integrate reviews into your own product. [](https://whitepaper.ethos.network/ethos-mechanisms#future-opportunity) Future opportunity ------------------------------------------------------------------------------------------------ Opinions and true feelings are often lost to fear of social repercussions. Ethos reviews today are onchain and require a profile, so everyone can see exactly how people perceive each other. If the highest social signals we can get are from _anonymous_ opinions, how can we leverage the Ethos credibility score to qualify those? We intend to eventually enable zkProofs for reviews, allowing people to anonymously review people with the qualifier of "Credibility score range," enabling reviews such as "A highly credible person has negatively reviewed Bob" Without the credibility score calculation, anonymous reviews lack any qualification to appropriately separate noise (spam from unreputable people) from signal.

A market is intended to be attached to an identity that users want to speculate on the reputation for; it could be an individual user, a company or corporation, a DAO, or even an autonomous entity. The amount of markets available will start limited and controlled by Ethos Labs as a means of focusing liquidity into specific markets and giving all users the best possible experience. #### [](https://whitepaper.ethos.network/ethos.markets#trust-percentages) Trust percentages Every market has a current Trust/Distrust score based on the current price of trust and distrust votes. This is intended to act as a proxy for how trusted or distrusted someone or something is. At the start, the market starts at 50:50. Buying trust votes increases the price of trust votes and the overall score. This also lowers the price of distrust votes to provide equilibrium to the market. **A pragmatic example might be:** You see someone highly credible like Vitalik at a trust score of 35%. You believe Vitalik is more trustworthy than 35%, so you buy trust votes because you believe his current market price does not correctly reflect his trustworthiness. You believe you can net a profit because his trust score will go up once the "trust market price" has been realized. It's important to understand that these markets are **perpetual**, and do not resolve. This because trust can never truly be resolved at a point in time However, you can imagine derivatives markets that could exist in the future resolve at certain points in time, ie. Vitalik will be above 80% before the end of 2025. ### [](https://whitepaper.ethos.network/ethos.markets#implementation-and-liquidity) Implementation & liquidity Ethos Reputation Markets execute on an Automated Market Maker (AMM) smart contract, using a standard Logarithmic Market Scoring Rule (LMSR) algorithm to price two opposite positions. This is the same pricing algorithm used by Polymarket. As an automated market liquidity is managed algorithmically rather than via traditional bid/ask spreads. Ethos Reputation Markets used a fixed liquidity control per market. These markets will continue to 'swing' with the same amount of volume, no matter how many total assets are locked. This has the following benefits: * You are never "too late to the party." Your votes have the same impact as the first market participants. * Markets respond quickly to changing sentiment. It does not require those with the largest holdings to shift positions before the market adapts. * Nobody is required to add liquidity. There's no liquidity crunch as people exit the market. Despite offering a built in "short-like" position, these contracts cannot be short squeezed. For future upgrades, the Reputation Market contract implements a graduate function that allows adoption of future algorithms and implementations, with agreement from the market owner. Note that because Reputation Markets are not prediction markets and do not resolve, they are not "binary options" but lack a formal economic definition; then nearest would be a "binary perpetual." ### [](https://whitepaper.ethos.network/ethos.markets#contrasts-to-ethos.network) Contrasts to Ethos.Network Ethos.network and Ethos.markets work as independent but complementary products. The vast majority of people will have Ethos.network accounts but not a market on Ethos.markets. This is due to some constraints around Ethos.market's reputation market design: * There is not enough liquidity in the world to support every user having their own Ethos market. * Ethos.markets ONLY lets people speculate with money, and lacks other social signals like free reviews. * A reputation market has pure financial upside and downside, and could muddy & conflate social signals of "I don't want to lose money" with "I don't trust this person" - something that's much more clear on Ethos.network [](https://whitepaper.ethos.network/ethos.markets#acknowledgements-and-contributors) Acknowledgements & Contributors ------------------------------------------------------------------------------------------------------------------------- This concept was originally from a conversation we had with [@CL207](https://x.com/CL207) , originally in late 2023 and then again in September 2024. Both CL and the Ethos team were inspired by what Friend.tech could be ([CL's thesis](https://www.egirlcapital.com/writings/181712053) , [our thesis](https://x.com/0x5f_eth/status/1706341407672148477) ) but it was missing one key part - you could only buy keys, you couldn't take the sell side. CL casually pitched the idea to us but wasn't sure how to implement it, so we did. He will always be considered an original contributor to the thesis.

AcceptReject --- # Principles | Ethos ### [](https://whitepaper.ethos.network/governance#you-are-your-actions) Credibility is collective > Society runs on trust. We all need to trust that the random people we interact with will cooperate. ... If too many people steal or too many people don’t pay their taxes, society no longer works. > > \-- Bruce Schneier, [Trust and Society](https://www.schneier.com/essays/archives/2013/02/trust_and_society.html) No one authority can define credibility. It's a balance of personal judgement and group norms. Signs and signals will evolve with our culture. Principle: any credibility score needs to adapt to collective input. ### [](https://whitepaper.ethos.network/governance#algorithms-are-convenient) Algorithms are convenient However, standard credibility assessments provide market efficiencies. Few have time to perform deep due diligence on every transaction. Traditional market (tradfi) institutions like the SEC and credit report bureaus ensure a minimum threshold via licensing, regulation, and monitoring. Meanwhile ratings and reviews allow web2 consumers to "check for themselves" but still rely on centralized systems. Principle: a credibility score needs to be legible and concise. ### [](https://whitepaper.ethos.network/governance#credibility-is-power) Credibility is power High credibility brings financial rewards. Defining credibility in a market grants influence. How that power is used depends on incentives. Market makers (Uber, eBay) benefit from trust in sellers and buyers. Some, like Amazon, extract fees from sellers to hijack credibility via paid reviews and ad-based placement. Others, like Yelp and Glassdoor, repeatedly face accusations of extorting businesses by suggesting paid plans may help dispute low ratings. Principle: avoid centralized incentives to tamper with credibility for profit. ### [](https://whitepaper.ethos.network/governance#algorithms-change-behavior) Algorithms change behavior People will shape their behavior according to what a credibility algorithm rewards. People's livelihood depends on how a centralized algorithm ranks their credibility. When these algorithms are centralized and owned by organizations, obtuse changes can alter careers and fortunes. For example, YouTubers are in a constant cat-and-mouse game reverse engineering the monetization algorithms. Principle: one must have the ability to influence an algorithm that impacts their livelihood. ### [](https://whitepaper.ethos.network/governance#algorithms-will-be-abused) Algorithms will be abused > "the optimal amount of fraud is greater than zero." > > \-- Patrick McKenzie, [Bits about Money](https://www.bitsaboutmoney.com/archive/optimal-amount-of-fraud/) Any summary will omit details, so credibility scores can't fully represent the truth. This wiggle room allows abusers to optimize to the point where it defeats the original purpose. Centralized management historically fails; there is no way to perfect the algorithm or police all fraud. Instead, rely on the people most impacted to define the trade-offs between usefulness and abuse. Principle: collective governance will ensure a credibility score reflects effective trade-offs between usefulness and abuse.
