POA is an Ethereum-compatible public blockchain that uses proof-of-authority consensus, originally built around identified United States public notaries serving as validators. POA's Twitter Score is 50 out of 1000 (a Good rating) as of August 2026, ranking #17,809 (top 5%) among 482,922 tracked accounts.
POA was founded by Igor Barinov, alongside Viktor Baranov and Pavel Khahulin, who together authored the original whitepaper, with its first draft distributed on October 4, 2017. The network's validator set was drawn from publicly identified notaries, who also participated in governance decisions through on-chain applications. Barinov originated the xDai stable-chain concept, and POA developed the interoperability infrastructure, including TokenBridge, that underpinned the xDai ecosystem.
POA is now part of the Gnosis ecosystem. The POA-to-STAKE token swap expired on May 5, 2022, after which the official site indicated the network would continue in a staging capacity without value-based emissions or rewards. POA tokens remain usable for transaction fees on the network, though the official site notes they have been delisted from reputable exchanges and should not be purchased with an expectation of financial value.
POA has published 787 posts and has 17,503 followers as of August 2026. POA has been mentioned by 223 accounts, with 561 total mentions.
