Next validation:
To minimize the probability of a Sybil attack, the pace of network growth is restricted: Idena network participation is invitation-based. New invitations can be sent out only by validated users. The number of invitations is limited and increases as the network grows.
Please choose the platform where you have the most active account:
Join the official Idena Telegram group and request an invitation code from the community.
Join Idena Community Discord and request an invitation code from the community in #invite-requests
channel.
Join Idena subreddit and request an invitation code from the community
Validation ceremony is a time-sensitive event. It requires users to be strictly on time and to use the latest version of Idena app to be able to participate in validation. Even 1 minute late or outdated app version could lead to failure.
Next validation:
Your cryptoidentity status is valid until the next epoch. You should prolong your validation status for every new epoch.
