After three months of voting and testing, Tezos ($XTZ) on-chain protocol Athens A will be implemented May 29th at block 458,752. As a proof-of-stake protocol, stakeholders have to vote for on-chain governance issues, with Tezos using a vote or delegate system which increases participation. Athens A will increase the gas limit on Tezos blocks and reduce the minimum amount of tokens needed to become a baker.
