Sui vs Solana, what is the difference?

Sui vs Solana is a comparison of two layer 1 blockchains built for speed. Both run transactions in parallel and both rely on staked validators. The main differences are the programming language, how on-chain data is organized and how each network reaches agreement.

How does Sui vs Solana Move vs Rust compare?

Solana programs are mostly written in Rust, often with the Anchor framework. Solana programs are stateless. The data they work on lives in separate accounts, and each transaction must declare upfront which accounts it will read or write.

Sui uses Move, a language built around resources. Sui's docs explain that assets in Move cannot be copied or thrown away unless the code explicitly allows it, which is meant to make token handling safer. On Sui, all on-chain data is stored as objects, and every object has an owner. An owned object can only be used by its owner, while a shared object can be used by anyone under rules set in the contract.

Access control follows the same split. Solana programs check signers and account ownership. Sui contracts often use capability objects, so a call fails if the caller does not hold the required object.

What is the difference in Sui vs Solana speed?

Both chains are fast, but they measure speed differently.

Solana's slot time, the window in which one leader produces a block, dropped from 400 milliseconds to 200 milliseconds in steps that were completed on October 9, 2026. Under its current Tower BFT voting, Solana puts finality at about 12.8 seconds. Its Alpenglow upgrade, scheduled to activate on mainnet from October 21, 2026, targets finality of around 150 milliseconds.

Sui uses a DAG-based consensus protocol called Mysticeti, run by validators chosen through delegated proof of stake. Sui reports sub-second finality for simple transactions and about 390 milliseconds for transactions that touch shared objects.

How do Solana vs Sui fees and storage differ?

Solana charges 5,000 lamports per signature, half burned and half paid to the validator, plus an optional priority fee. Accounts that store data must hold a minimum balance to stay rent-exempt.

Sui gas has two parts, computation and storage. Validators set a reference gas price at the start of each epoch. Storage fees go into a storage fund, and when a transaction deletes stored objects the user gets most of that fee back as a rebate, initially 99%.

How do Solana vs Sui transactions combine actions?

Sui uses programmable transaction blocks that chain up to 1,024 calls in one atomic transaction, with outputs feeding later calls. Solana transactions can also hold several instructions that succeed or fail together, and programs can call other programs up to four levels deep. For a related comparison, see Ethereum vs Solana.
