Key Differences in Move-Based Blockchains

• Aptos, Sui, and Movement chains utilize the Move language but differ in architecture.
• Sui offers the fastest Time to Finality at 0.5s, with Aptos at 0.9s and Movement at 1s.
• Aptos leads with 186+ ecosystem projects, while Sui and Movement have fewer in development.

Move-based blockchains are becoming increasingly popular in the crypto world. Aptos, Sui, and the upcoming Movement blockchain have captured the interest of both developers and investors. While all three chains utilize the Move programming language, their designs have key differences that affect their performance, consensus mechanisms, and transaction speeds.

Blockchain Architectures and Consensus Mechanisms

Aptos and Movement use linear chain architectures, while Sui uses a Directed Acyclic Graph (DAG) structure. Aptos relies on its own AptosBFT (Byzantine Fault Tolerance) consensus mechanism to ensure secure and fast transactions. Sui uses the Mysticeti consensus, which is built on DAG-based BFT and allows for even faster transaction processing. Movement uses Avalanche’s Snowman consensus, known for its efficiency in decentralized networks.

Aptos has a Time to Finality (TTF) of about 0.9 seconds. Sui takes the lead with around 0.5 seconds, while Movement has a slightly longer finality time of about 1 second. These speeds show how quickly each chain confirms transactions.

Aptos and Movement both use Block-STM parallel execution for transaction processing, allowing them to handle many transactions at the same time. Sui, however, uses a State Access Parallelisation technique, which focuses on making state access more efficient.

The theoretical transactions per second (TPS) vary across the three blockchains. Sui boasts the highest, with a TPS of 297,000. Aptos and Movement both achieve around 160,000 TPS. These impressive speeds show their potential for handling large-scale applications and user bases.

When it comes to ecosystem projects, Aptos is in the lead with over 186 active projects. Sui follows with more than 86, and Movement has roughly 46 projects under development. These numbers reflect the growing interest and investment in these platforms.

Aptos, Sui, and Movement will continue to develop as developers explore the full capabilities of the Move programming language. Each chain currently offers unique features that cater to different needs in the blockchain space.
