Sui and Aptos: The Move Language Blockchains in 2026
Sui and Aptos both use the Move language from Meta's Diem project. Here is how they compare and what to use them for.
Sui and Aptos are both built using the Move programming language (originally developed for Meta's Diem/Libra project) and were both launched in 2022-2023 by teams that spun out of Meta. They offer fast throughput, low latency, and a more type-safe smart contract language than Solidity. In 2026, both have developed distinct ecosystems and use cases.
Sui in 2026
- Throughput: 300,000+ TPS theoretical capacity — practical throughput far exceeds all other L1s
- Object-centric model: unique Sui-specific programming model enables parallel transaction processing
- DeFi: Cetus Protocol (DEX), Scallop (lending), Aftermath Finance (DEX) — growing ecosystem
- Gaming: Mysten Labs' own gaming focus drives consumer applications
- SUI staking: 4-6% APY, 7-day unbonding period via Steyble integration
Aptos in 2026
