Aptos and Sui emerged from the same origin — the Meta/Facebook Diem blockchain project and its Move programming language — but diverged in their technical approaches and strategic positioning. Aptos was founded by Mo Shaikh and Avery Ching (both ex-Meta/Diem leads) and raised $350 million before launching mainnet in October 2022. Where Sui adopted an object-centric state model, Aptos stayed closer to the account-based model familiar from Ethereum and Solana but with Move's safety properties applied. This made Aptos more immediately accessible to existing blockchain developers while still providing the formal verification and resource-safety advantages of Move. Aptos has emphasised institutional partnerships and enterprise reliability as differentiators — targeting the intersection of high-throughput DeFi and institutional use cases including RWA tokenisation, where security guarantees and regulatory-friendly architecture matter as much as raw performance.
Block-STM: Parallel Execution on an Account Model
Aptos's parallel execution engine, Block-STM (Software Transactional Memory), solves a different problem than Sui's object model. In Ethereum and most account-based blockchains, transactions are executed sequentially — one after another — because any transaction could read or write the same state. Block-STM uses optimistic concurrency control: it assumes transactions can be executed in parallel and detects conflicts after execution, re-executing only the conflicting transactions. The process: transactions in a block are speculatively executed in parallel across all available CPU cores. After parallel execution, the runtime checks for conflicts (cases where two transactions read and wrote the same state). If a conflict is found, the later transaction is re-executed. For workloads where most transactions are independent (e.g., token transfers, different DeFi protocol interactions), Block-STM achieves near-linear throughput scaling with the number of CPU cores — theoretical throughput of 150,000+ TPS in benchmark conditions. For workloads with high contention (many users interacting with the same protocol state simultaneously), Block-STM falls back toward sequential execution, limiting practical throughput during DeFi peak demand. The Block-STM implementation is public, open-source, and has been adopted or studied by multiple other blockchain projects seeking to add parallel execution to account-based models.
Move on Aptos: Safety by Construction
Aptos uses the original Move language as designed for Diem — slightly different from Sui's adapted version (the developer community refers to them as "Aptos Move" vs "Sui Move"). Both share the core properties: linear type system preventing asset duplication or accidental destruction, formal verification tooling for proving smart contract correctness, and explicit ownership semantics. Aptos's Move has module-level access control (modules are the unit of code deployment, controlling which functions are publicly callable), strong typing that makes cross-contract vulnerabilities significantly harder to introduce, and a well-developed formal verification framework (Move Prover) that can mathematically prove certain correctness properties about contracts. For DeFi protocols handling large sums, formal verification is not an academic exercise — several DeFi exploits worth hundreds of millions have exploited vulnerabilities that formal verification would have caught.
Aptos DeFi and RWA Ecosystem
Liquidswap and Thala are the primary DEXes by TVL. Aries Markets provides lending and borrowing. Merkle Trade offers perp futures trading on Aptos. On the institutional side, Aptos has been aggressive in pursuing RWA (Real World Asset) partnerships: Franklin Templeton deployed an on-chain money market fund on Aptos, joining a small group of blockchains (Ethereum, Stellar, Polygon) hosting regulated fund products. Microsoft's Azure cloud infrastructure has partnered with Aptos for enterprise blockchain deployments. The Aptos Foundation has maintained a strong grant programme supporting developer activity, which has sustained ecosystem growth despite lower retail visibility than Solana-ecosystem competitors. Aptos's DeFi TVL has been growing steadily, reaching $1B+ in 2025, but remains well below Ethereum's $80B+ — the gap reflects the early stage of the ecosystem rather than a technical shortcoming.
APT Tokenomics and Vesting Concerns
APT's total supply is 1 billion tokens. Like Sui, the initial token distribution gave significant allocations to the team, Aptos Foundation, and early investors (~51% combined), with multi-year vesting schedules creating ongoing token unlocks. The APT price has been significantly impacted by the regular release of previously locked tokens entering the market. Understanding the vesting cliff dates — when large tranches of locked APT become available for sale — is essential for any APT position. Both Aptos and Sui face the same structural challenge: technically strong platforms with genuinely novel innovations, but token supplies that create persistent sell pressure from insider unlocks for the first several years post-mainnet. The long-term investment case requires believing that ecosystem growth (fee revenue demand for APT, staking demand, DeFi TVL) will outpace unlock-driven supply inflation over a multi-year horizon.
Aptos DeFi Ecosystem
Aptos's Block-STM parallel execution engine processes transactions optimistically in parallel and detects and re-executes only the small subset that conflict — a sophisticated approach that achieves high throughput on typical transaction workloads without requiring developers to design applications specifically for parallel execution. This transparent parallelism is developer-friendly: existing Move contracts benefit from Block-STM acceleration without needing modification, unlike systems where developers must manually specify parallelism constraints.
Aptos's DeFi ecosystem has grown rapidly with Liquidswap (AMM DEX), Aries Markets (lending), Merkle Trade (perpetuals DEX), and Thala Labs (CDP stablecoin protocol) providing core financial infrastructure. The ecosystem benefits from Aptos's Meta (formerly Facebook) heritage — a well-funded development team with strong engineering talent, established institutional relationships, and experience building consumer-grade applications at scale. APT trades on Binance, Bybit, Coinbase, and OKX. Our staking guide covers Aptos's delegation model. Use our crypto tools for APT analysis and our DennTech blog for Aptos ecosystem updates.
Aptos's keyless account standard — built on zkLogin-style ZK proofs over OAuth credentials — allows wallets to be recovered through the same email or social account used at creation, solving the seed phrase loss problem for mainstream users. This account recovery model could dramatically reduce the user experience gap between web2 apps and web3 applications, making Aptos-based applications viable for consumers who have never managed a seed phrase and have no intention of doing so. The combination of Block-STM throughput and keyless accounts positions Aptos as infrastructure for consumer-scale blockchain applications reaching audiences beyond the existing crypto-native user base.
