Proof of Attendance Protocol (POAP) ceases operation after more than five years of existence. The Block reported.

According to the publication’s briefing, 46 210 issuers, including Coinbase and American Express, used POAP to create on-chain attendance memorials that users could mint.

For the market, this means the end of a notable example of applying blockchain to record participation in events. However, available material is insufficient to assess impacts for users, issuers, and already created objects.
