Proof of Attendance Protocol, known as POAP, is shutting down after more than 5 years online. The onchain badge system once counted 46,210 issuers, including Coinbase and American Express, raising a hard question about how long any Web3 memory tool can survive without new infrastructure.
What actually happened
POAP describes itself as a way to turn real world and online attendance into onchain proof, minted as a collectible badge. Over more than 5 years of operation, 46,210 issuers used the protocol to create these onchain mementos, according to The Block. That issuer list included Coinbase and American Express, two of the most recognizable names to touch crypto infrastructure. The report does not specify an exact shutdown date, nor a stated reason from the POAP team. No official statement from POAP is quoted in the available reporting. The scale of 46,210 issuers shows how far a simple badge idea traveled across both crypto native platforms and mainstream brands before the service reached its end.
How we got here
POAP launched as one of the earliest attempts to give onchain identity a timestamp, letting people prove they showed up to a conference, a mint event, or an online call. It became a common badge for hackathons and community meetups, cited well beyond crypto circles once Coinbase and American Express adopted it. For years it stood almost alone in its niche, with few competitors offering the same simple mint-to-prove model. That lack of iteration matters now. POAP built its core idea early and largely kept the same approach, without folding in newer tools like account abstraction or smoother onchain infrastructure that could have lowered costs and friction for issuers and holders alike.
Why this matters for you
For holders, existing POAP badges do not disappear from wallets, but the service that issued new ones is ending, closing an entire category of attendance minting. For event organizers and brands, the shutdown removes a familiar tool, pushing them to find replacements or build in house. For builders, the gap is now open: a proof of attendance system built on modern rails, with account abstraction and cheaper onchain infrastructure, could fill the space POAP leaves behind. Systems like bonuz already combine proof of participation, proof of attendance, and proof of visit with onchain memberships, loyalty cards, and vouchers, layered into AR experiences. That broader, more current approach shows one direction the category could take next.
The bigger question
If a pioneer like POAP, used by 46,210 issuers, can shut down after 5 years, what does that say about the durability of any onchain memory system? Should proof of attendance be built on infrastructure designed to last for decades, rather than depend on one company's servers? And who ultimately decides which records of presence deserve to survive?
What to watch
No official shutdown date, wind down timeline, or migration plan has been published in available reporting. Holders and issuers should watch for an official statement from the POAP team confirming how existing badges will be preserved. Any replacement service claiming to fill this space should be judged on whether it uses modern onchain infrastructure, rather than repeating POAP's original design without updates.
