Photographs capture a moment in time and allow us to relive our memories, but with web3, there exists an even more powerful way for that memory to be stored. It can be minted, added to a wallet, and remain on-chain forever. Proof of Attendance Protocol (or POAP for short) gives users the ability to collect attendance-based NFTs as verification of their presence at various events, notably in the metaverse as well. POAP has been applied to everything from the virtual lands of Decentraland to the physical-world US Open, enabling users to create and record memories in both worlds. However, the power of POAPs goes even further beyond this. POAP could become a useful tool for employers, shape how the metaverse is built and experienced, and even potentially be the backbone for a new form of social media.
