IOST

IOST is a Layer 1 blockchain network launched on 11 January 2018, designed to provide very high transaction throughput for decentralized applications and online services. It targets developers and businesses that need a scalable foundation for building internet-scale services without relying on centralized infrastructure. The project describes its goal as becoming the underlying architecture for a decentralized economy, addressing the well-known tension between speed, security, and decentralization.

IOST uses a consensus mechanism it calls Proof-of-Believability, which selects validators using a combination of IOST token balance, a reputation-based token balance, network contributions, and user behavior, then applies a Byzantine Fault Tolerance mechanism to finalize blocks. The protocol also incorporates microstate blocks, an Atomic Commit protocol, and a dynamic sharding approach called Efficient Distributed Sharding to reduce storage and processing demands on validators while keeping transactions consistent. The IOST token is used to pay for network resources, participate in node validation, and accrue reputation within this system.

The data provided does not include a fee revenue figure, so no fee stream, fee recipient, or protocol earnings can be reported here, and the fee-based measures typically shown on this site are not applicable to IOST as currently stored. What the data does show is that the circulating supply stands at 36,037,355,666 IOST tokens, representing approximately 40.04 percent of the 90,000,000,000 maximum supply at this point in time. The fully diluted valuation equals the market capitalization, meaning a dilution overhang of 0.0 percent is recorded, and supply-pending issuance is also 0.0 percent, indicating that no additional tokens beyond those already circulating are scheduled or tracked as pending.
