Aptos and Sui Diverge in Architecture and Adoption

Aptos and Sui are two blockchain networks that share a common ancestor in Meta's Diem project, which was shut down in 2022. The engineers who worked on Diem split into two groups: Mo Shaikh and Avery Ching founded Aptos Labs, while Evan Cheng and Sam Blackshear founded Mysten Labs, the company behind Sui.

Although both chains use the Move programming language, they process transactions differently. Aptos uses an account-based model with a parallel execution engine called Block-STM, similar to Ethereum's balance tracking system. In contrast, Sui employs an object-centric model where every asset is a unique object with its own owner.

This difference in architecture has led to varying outcomes for the two chains. Sui's staking APR currently sits near 7%, giving it a clear yield advantage over Aptos, which recently implemented a hard supply cap of 2.1 billion APT tokens and reduced staking rewards from 5.2% to 2.6% annually.

Aptos has also seen significant growth in institutional adoption, with $1.2 billion in real-world asset deployments from BlackRock and Franklin Templeton. In contrast, Sui leads in DeFi and trading activity, processing roughly 3.5 times Aptos's decentralized exchange volume as of March 11, 2026.
