Sui's From-Scratch Approach Brings Parallel Execution and Sub-Second Finality

Sui's creators chose to build their blockchain from scratch rather than forking an existing one like Ethereum or Solana. The team, mostly comprised of engineers who worked on Meta's Diem project, wanted a data model and programming language that no existing blockchain offered.

Using the Move programming language and its asset-safety guarantees was crucial to Sui's architecture. This allowed them to treat every digital asset as an object with a unique ID and owner, rather than just a line in one shared ledger. By doing so, validators can quickly determine when two transactions are unrelated.

Sui separates transactions into two paths: simple transfers that touch only owned objects skip full consensus and finalize once validators sign off, while those touching shared objects go through Mysticeti, a directed-acyclic-graph consensus protocol that reached mainnet in July 2024. This allows for parallel execution and sub-second finality on shared-object transactions.

As of early July 2026, SUI trades around $0.72 to $0.74, with roughly 4 billion of the fixed 10 billion token supply in circulation, according to CoinGecko and CoinMarketCap data. The network's DeFi total value locked has ranged between roughly $440 million and $900 million through the first half of 2026.
