WEWO 基于比特币现金(Bitcoin Cash)的去中心化微博,实现并 扩展MEMO协议

WEWO protocol

Protocol uses P2PKH addresses. Actions are saved using OP_RETURN.

Action Prefix Values
PostBlogHeader 0x7701 BlogId(4), ChunksCount(2), Title(up to 67)
PostBlogContent ox7702 BlogId(4), ChunkIndex(2), Content(up to 67)


  • To post a blog, 1 0x7701 transaction and multiple 0x7702 transactions are needed. They should have the same BlogId and The ChunksCount in 0x7701 should be equal to the count of 0x7702 transactions.
  • The BlogId needs to be unique under each address, does NOT need to be unique between addresses. The length of BlogId is flexible. In WEWO, it's 4 bytes.
  • ChunkIndex starts from 0.
  • The content could be compressed or not. In WEWO, it's compressed with gzip.
  • After May 15 BCH upgrade, each 0x7702 transaction could send up to 207 bytes of content.
