Sui was constructed from scratch as a result of its engineering crew, most of whom labored on Meta’s Diem undertaking, wanted a knowledge mannequin and a programming language that no current blockchain provided.
Forking Ethereum or Solana would have meant inheriting an account-based ledger that processes transactions one after one other. That construction couldn’t ship the sub-second finality and parallel execution the crew was aiming for.
Why Did not Mysten Labs Simply Fork Ethereum or Solana?
Sui’s founders, working beneath Mysten Labs, got here out of Meta’s Diem (previously Libra) undertaking. When Diem was shut down by regulators in 2022, the crew saved two issues: the Transfer programming language and hands-on expertise attempting to maneuver digital property at web scale.
Forking an current chain would have carried over its core limits too.
- Ethereum’s account-based mannequin updates one world ledger, so unrelated transactions nonetheless queue up in sequence.
- Solana reaches excessive throughput however leans on more and more highly effective, specialised validator {hardware} relatively than horizontal scaling.
- Neither chain was designed round Transfer, so a fork couldn’t use Transfer’s asset-safety ensures with out a separate digital machine rewrite.
Reasonably than patch round these constraints, the crew designed a brand new object-centric information mannequin paired with a brand new consensus engine.
What Drawback Was Sui Attempting To Clear up?
The core difficulty was easy: as extra individuals use a blockchain, it often slows down and costs rise. Sui’s structure treats each asset (a coin, an $NFT, a bit of contract state) as its personal object with a novel ID and proprietor, as a substitute of a line in a single shared ledger.
As a result of most transactions solely contact objects the sender already owns, validators can inform straight away when two transactions are unrelated.
Unbiased Transactions Run In Parallel
A switch of $SUI between two wallets and an unrelated $NFT commerce don’t want to attend on one another. Sui processes them on the identical time as a substitute of queuing them behind each other, the way in which Ethereum’s sequential mannequin does.
How Does Consensus Match Into This Design?
Sui separates transactions into two paths. Easy transfers that contact solely owned objects skip full consensus and finalize as soon as validators log off. Transactions touching shared objects, similar to a decentralized alternate pool, undergo Mysticeti, a directed-acyclic-graph consensus protocol that reached mainnet in July 2024.
Mysticeti eliminated the leader-based bottleneck utilized by its predecessor, Narwhal and Bullshark, and now commits transactions in roughly 390 milliseconds beneath practical community situations, primarily based on inner Mysten Labs benchmarks.
Why Transfer Issues Right here
Transfer treats digital property as sources that can not be copied or by accident destroyed, a rule enforced by the language itself relatively than by developer self-discipline. This closes off a class of bugs frequent in Solidity, the place balances are simply numbers in a mapping that may be manipulated if code has a flaw.
The place Does Sui Stand As we speak?
As of early July 2026, $SUI trades round $0.72 to $0.74, with roughly 4 billion of the mounted 10 billion token provide in circulation, in keeping with CoinGecko and CoinMarketCap information.
The community’s DeFi complete worth locked has ranged between roughly $440 million and $900 million via the primary half of 2026, down from a late-2025 peak close to $2.5 billion, reflecting broader market pullback and token unlock strain relatively than a change within the underlying structure. Roughly 100 validators presently safe the community beneath delegated proof of stake.
Conclusion
Sui’s from-scratch strategy offers it an object-centric mannequin for parallel execution, the Transfer language for asset security, and Mysticeti consensus for sub-second finality on shared-object transactions. These three items work collectively particularly as a result of they had been designed as one system relatively than bolted onto an current chain’s guidelines.
