Memorychain was a Japanese user-generated content collection aiming at depicting and commemorating significant events, people or projects in the blockchain industry.
There were multiple artists and a community telegram that curated and voted on submissions. Information about this early community and project is hard to come by now.
However these amazing artworks that are laden with blockchain history are left as valuable relics from this period. The first asset of the collection was WACKNAKAMOTO.
Lead innovator Koji Hagigashi has recently written an article and developed an explorer providing some amazing insight into this early project and others.
