The Walrus protocol launched by Sui developer Mysten Labs announced its token economic model, with a total supply of 5 billion WAL tokens and an initial circulation supply of 1.25 billion. The distribution of WAL tokens is as follows: 10% for Walrus user airdrops, 43% for community reserves for funding, developer support and incentive programs, 30% for core contributors, 10% for subsidizing storage nodes, and 7% for investors, with an unlocking period of 12 months after the mainnet is released.
