Idena is the first Proof-of-Person blockchain based on democratic principles. Every mining node is linked to a cryptoidentity – one single person with equal voting power and mining income.
Every unique human can become an Idena validator no matter who they are and where they live. To start mining Idena, you need to prove you are a unique human. It does not require the disclosure of any personal data (no KYC). You need to appear online when the validation ceremony starts and solve a series of flip-tests (CAPTCHAs).

Anonimity and sybil-resistant cryptoidentity. It’s semi-unique which means you can easily validate one account, but it’s much harder to get two and impossible to get many accounts. It can not be bought and sold, its value grows with age, it can not be taken over. Anonymous and Sybil-resistant identity is a missing part for Web 3.0.
No authorities. Cryptoidentity is mutually verified by users with no central authority in the peer-to-peer network. It is anonymous, self-managed, and valid globally. Cryptoidentity has no central issuer, so it can not be banned, restricted or censored.
Equal human rights. All cryptoidentities in Idena have equal rights: to validate other identities, to vote, to verify transactions. Self-sovereign, decentralized and anonymous cryptoidentity prevents human rights abuse by the powerful, and supports the rights of the individual to be oneself and to freely associate.
Sharding + Cryptoidentity = Scalability Scalable blockchain performing thousands of transactions per second can be built without compromising its safety and decentralization. Sharding combined with cryptoidentity is the solution to the blockchain trilemma: network throughput increases with the number of validated users forming more and more new shards.
Instant finality. Idena implements a Proof-of-Person Sybil control mechanism and committee-based BFT consensus with fast finality. Every block mined by Idena validators is final with almost 100% probability, which means that blockchain forks are almost not possible. You need to wait just 2 blocks to make sure your transaction will be never reverted.
Eco friendly mining. Idena blockchain is driven by eco-friendly Proof-of-Person consensus. To verify transactions, Idena miner needs to have a valid cryptoidentity and keep their node online. Mining income does not depend on your hardware. It doesn’t require to use up high volumes of electricity, GPUs or mining rigs.
Limitations and risks
L1 blockchain. Idena runs on a dedicated blockchain developed to support the high network load during the validation ceremony. Compared to L2 solutions, decentralized integration is harder but offers low transaction costs.
Idena validation is and will remain free for everyone. To keep the status of the cryptoidentity, the user has to take part in regular validation ceremonies every 20 days or so. On the other hand, it guarantees up-to-date identity status and gives much stronger sybil protection.
