Idena Beginner Guide

By definews | Defi News | 3 Oct 2020


Idena is the first Proof-of-Person Blockchain. No money for stake or equipment needed, just an average laptop. You can easily join mining of the first human-centric cryptocurrency at We should solve puzzles it called FLIPS to prove thats we are human not bot if we want to work as a node. Every single node is equivalent to one person.

Proof of person

The Idena network allows for a proof of humanity and proof of uniqueness for its participants. We call it Proof-of-Person (PoP). Idena does not require any personal data sharing, does not reveal a person’s identity, and does not need a third-party identification center. Idena is based on a network of people mutually validating their humanness and uniqueness. How is it possible?

Idena employs regular checkpoint rituals — synchronous validation sessions — to certify a participants’ humanness for the consequent epoch. The validation requires solving of “flips-puzzles” easy for a human, difficult for a bot.

The uniqueness of participants is proven by the fact that they must solve flip synchronously. Flips are decrypted at the same time worldwide. A single person is not able to validate herself multiple times because of the limited timeframe for the answers submission.

After the validation session is over, the network reaches consensus about the new list of validated participants, and the date of the next validation session is scheduled. The bigger the network is, the less frequently the validation sessions happen.The validation status of a participant is not forever. It expires when the next epoch starts. Participants should prolong their validation status for every new epoch.To be allowed to take part in the next validation round, the participant must provide a certain number of newly created flips.To join the network, a new person must get an invitation from a validated participant.

Where to start?
1. Visit the website to learn more about Idena.
2. Download and install the Idena Node and Idena Client executable files at Idena official website or build them from source at Github.
3. Subscribe to the Idena Announcements channel at Idena Official Channel or choose local idena telegram group to follow updates.
4. Join the Idena Telegram chat Idena Network Public and follow the instructions in the pinned message.
5. Make sure your node is synchronized, and activate the invitation code. Check your identity status; it should be "Candidate". The invitation can not be activated in last 5 minutes before the validation. You should synchronized 3 hour before validation time for safest way.
6. Learn how to create good flips and solve flips:

7. Read the article in and test yourself

Idena is a strong bot protection: one person can not have multiple accounts, because the validation session starts at the same time globally. Useful for many projects that cannot be realized otherwise: true anonymous authentication, privacy-preserving Sybil-protected governance and fair voting for online communities and DAOs, global universal basic income initiatives, Sybil-protected marketing.

How to get validated?
1. Check the next validation time in the Idena app or at the website.
2. Your node must be fully synchronized before the session starts.
3. Your computer time must be synchronized with the internet time.
4. Solve the flips during the validation session. Be agile. The first 6 flips must be submitted in less than 2 minutes.

What's next?
1. Once your identity is validated, keep your node up and running in order to mine coins.
2. Learn how to create flips. Don't forget to create three fips  before the next validation in advance. Schedule your next validation.

The person who invites you can terminate your identity only before your status is "Verfied", after the third validation it is no longer possible. This is done to prevent participants from buying and selling invitations and to encourage healthy network growth. When you are invited by your friend you will not be expelled.Individual must validate themself in order to mine coins.The uniqueness of participants is proven by the fact that they must solve and provide the answers for flip-puzzles synchronously. A single person is not able to validate herself multiple times because of the very limited timeframe for the submission of the answers.
