# EtherScore A decentralized reputation system By [Airdrop Alert Daily](https://paragraph.com/@airdropalertdaily) · 2022-11-04 --- What is EtherScore? ------------------- Etherscore’s Soulbound Tokens / NFT Badges Deliver On-Chain Proof of Experience !\[How it works?Decentralized community curation Etherscore enables dApps to better identify their reliable user by distributing badges (NFTs) based on their in-app achievements. Badge ownership can be used to allow conditional access to different smart contracts, airdrops, or to unlock additional DAO voting power. EtherScore uses the concepts of Oracles and Ethereum Data Indexers to provide a truly decentralized solution. All EtherScore services will be payable in ETS, EtherScore tokens. ETS will also be used to transition to a community-driven DAO.\]([https://images.mirror-media.xyz/publication-images/wxfjKmhmzIk-wTo4drTKN.png?height=812&width=2874](https://images.mirror-media.xyz/publication-images/wxfjKmhmzIk-wTo4drTKN.png?height=812&width=2874)) **What are ETS tokens?** ETS tokens are used to access Etherscore services and participate in governance ![](https://storage.googleapis.com/papyrus_images/947584463da3947bdf2fd16fc07cb2ffaca8fb406b714978a8395b4a31ab0092.png) What is EtherScore? ------------------- * EtherScore creates NFT badges based on a user’s on-chain actions. They are indelible and can be used to certify experiences, provide proof of an accomplishment, or distribute incentives to certain classes of users. * User actions can include anything involving a blockchain, such as interacting with a DeFi platform in a particular way, belonging to a DAO, GameFi, or using a DApp. EtherScore’s Badge Factory allows developers to easily deploy customizable badges with parameters such as transferability, burnability, dynamicity, or supply. * Any user fulfilling the conditions set by the developers can mint or receive an airdropped NFT EthScore badge and enjoy the benefits. Why EtherScore? --------------- * Almost all blockchain projects experiment with an incentive mechanism to reward or encourage their users. Uniswap airdropped tokens, Coinlist deposited Karma, and UMA gave KPI options. They all relied on whitelists, often generated by third parties and off-chain data. * A whitelist is a blunt instrument. They can make sense when a single factor is considered, but each new variable makes a list much more difficult to assemble and unwieldy to use, particularly at scale. Whitelists lack the transparency and auditability that the crypto-community values, and can encourage free-riders and bad actors. * EtherScore solves a basic problem for blockchain organizations: how to find, recognize, and reward users over time. It provides a decentralized reputation system that can be completely customized to a developer’s needs. An EtherScore NFT badge places the onus for meeting the developer’s standards on the user. * EtherScore’s composability and the persistence of its NFT badges will allow a new class of reputation-based blockchain DApps such as curated social networks, DeSci, DeFi, GameFi and gaming achievements, fidelity programs, DAOs, and many more. EtherScore NFT Badges --------------------- * EtherScore Badges are NFTs representing users' achievements. As explained before, those badges can be used as an assessment of users’ experiences. Such assessments, being available on-chain, become accessible to Dapps and smart contracts which can implement access conditions based on it. Dapps can trust the authenticity of badges as they contain all information required for their verification. Badges can be used as a brick to build user profiles that are interoperable across the entire Ethereum ecosystem (pushing the concept of Ethereum Single Sign-On) and as a complementary tool to existing decentralized identity approaches such as Ethereum Name Service, Proof of Humanity or any blockchain identity-focused project. * Badges are composed of one or several minting conditions which represent the achievements required to be able to mint the NFT. A condition example could be "has already swapped on Uniswap" (some other badges examples are in part X). Conditions can be none (using the badge factory as traditional NFT airdrop) or multiple (conditions A and B). Various types of badges will then co-exist such as single-metric, multi-metric, evolutive (multi-threshold), blacklisters, and a lot of other features. Badge minting conditions ------------------------ Here is non-exhaustive list of metrics that can be used to issue EtherScore badges (note that any metrics available in our data sources can also be used): **Base layer usage (such as Ethereum usage)** * First transaction’s timestamp ("member since") * Gas burned amount * Mean transactions gas price * Max holding time, number of ETH hold * Miners / Stakers (blocks mined, reward received) **DeFi** * Early participants in protocol / airdrop recipient / airdrop holder * DEXs: number of swaps, LP provided, trade price etc. * Lending: lent value, borrowed value, flash loans, liquidations etc **Communities / DAOs** * Participants in DAO proposals (voters, delegators, proposal creators) * First holders * Official devs / contributors * Grants or Bounties recipient / Testnet participant / Gitcoin donator or recipient **Gaming / Metaverse** * Money spent in game * Number of items owned (or bought/sold) / having all items of a collection * First to complete a game / level * Various user profile statistics (winrate etc) * Any game specific achievement **Social Networks** * Number of posts * Number of likes * Number of followers * Amount received / donated in tips * Vouched by x person (if vouching) **Art NFT Marketplace** * Number of items bought / sold * Number of different collection bought * Number of NFTs / collections issued Thanks Dont for forget to collect this Articles. --- *Originally published on [Airdrop Alert Daily](https://paragraph.com/@airdropalertdaily/etherscore-a-decentralized-reputation-system)*
