Validators are selected through various considerations such as knowledge about Blockchain, background, merit, interest, and a willingness to commit to the network. New validators start by introducing themselves in the public forum, confirming their notary status and participating in discussions. Participating candidates may then be added to a ballot to serve as validators on the POA Sokol testnet. If they continue to participate, they may then be added to a ballot to join the POA Network validators. A current validator must add a candidate to the ballot, and a majority vote is required for a new candidate to join the network as a validator.
