Introduce After years of seeking regulatory compliance, Diem, a cryptocurrency payments project from Facebook/Meta, came to an abrupt end in 2022. Its assets were sold, including the underlying blockchain network. Two former Meta employees, Mo Shaikh and Avery Ching, were reluctant to accept the fate of a project they had spent nearly three years working on. So they decided to continue their work, only this time as CEO and CTO of the newly formed Aptos Labs.

Aptos Architecture

Aptos is running on the fourth iteration of their consensus protocol, Aptos BFT, which they claim is the lowest latency and most advanced iteration to date. This consensus protocol is a derivative of HotStuff, the underlying consensus protocol originally used by Diem. Recent additions to the system include: An innovative reputation system especially suited for decentralized environments that checks on-chain data and automatically changes leader rotation to resolve unresponsive validators without human intervention Block commits are now much shorter (down to 2), enabling sub-second finality. Protocol on Aptos

While Aptos is relatively new, developer activity has grown exponentially since the incentivized testnet first launched in early March of this year. For every new blockchain, the protocols that need the most attention are those that bring real value to the chain through infrastructure — similar to how money markets like Compound and oracles like Chainlink facilitate mainnet DeFi increase.
