The blockchain world has recently seen growing interest in a new generation of high-performance layer-1 networks founded by former Meta (formerly Facebook) engineers. Aptos, Sui, and Linera—often collectively referred to as the "Meta blockchain trio"—emerge from the ashes of Meta’s discontinued Diem and Novi projects. These networks aim to solve long-standing blockchain challenges such as scalability, security, and developer experience, leveraging innovative technologies like the Move programming language and parallel execution engines.
This deep dive explores the core features, technical innovations, and future potential of Aptos, Sui, and Linera—three projects reshaping the next wave of decentralized infrastructure.
The Origins: From Diem and Novi to Independent Innovation
Aptos, Sui, and Linera share a common lineage: their founding teams were instrumental in developing Diem (formerly Libra), Meta’s ambitious stablecoin initiative launched in 2019, and Novi, its associated digital wallet. Despite regulatory hurdles leading to the sale of Diem in early 2022 and the shutdown of Novi by September 2022, the engineering talent behind these projects didn’t vanish—they evolved.

Many core contributors transitioned into founding or leading new blockchain ventures. This shared heritage explains why Aptos, Sui, and Linera often appear together in discussions—they represent a cohesive vision for a more scalable, secure, and efficient web3 future, built by some of the most experienced minds in distributed systems.
Aptos: Speed, Security, and Scalability with Move
Among the three, Aptos stands out as the most mature and widely recognized. With $350 million raised across two major funding rounds—$150 million in seed funding (March 2022) and $200 million in Series A (July 2022)—it has attracted top-tier investors including a16z, Multicoin Capital, FTX Ventures, and Binance Labs.
Core Innovations
Move Programming Language
Aptos leverages Move, a language originally developed for Diem. Unlike Ethereum’s Solidity, which treats tokens as numerical values that can be duplicated or lost due to bugs, Move treats digital assets as resources—unique, non-copyable entities bound to accounts.
This resource-oriented model ensures:
- Tokens cannot be double-spent or created out of thin air.
- Assets must be explicitly used or transferred—never left in an undefined state.
- Each transaction includes a sequence number and chain identifier, preventing replay attacks across networks.
Moreover, Move enforces strict bytecode verification at compile time, catching vulnerabilities before deployment—a stark contrast to runtime-executed EVM contracts.
High Throughput via Block-STM
Aptos achieves exceptional transaction throughput using Block-STM (Software Transactional Memory), a parallel execution engine first prototyped during Diem’s development. By allowing multiple transactions to execute simultaneously while detecting data conflicts optimistically, Block-STM enables Aptos to scale efficiently even under heavy load.
Additionally, Aptos supports fast state synchronization for new nodes, reducing onboarding time and improving network resilience.
Flexible Key Management
Security extends beyond code. Aptos introduces dynamic key rotation, allowing users to update their private keys without changing their wallet address. This feature mitigates risks from key exposure and supports hybrid custody models—users can delegate key management rights to trusted entities under predefined conditions.
Gas Flexibility
Notably, Aptos does not require users to hold its native token to pay gas fees. Users can pay in other supported tokens, lowering entry barriers for new participants.
As of mid-2025, Aptos has progressed through multiple testnet phases with over 20,000 nodes active, paving the way for mainnet launch.
Sui: Parallelism and Predictable Economics
Developed by Mysten Labs, another spin-off from Meta’s Diem team, Sui differentiates itself through a unique consensus architecture and economic design focused on stability and user experience.
Backed by $176 million in funding—including a $36 million Series A led by a16z in December 2021 and a $140 million B round led by FTX in July 2022—Sui targets applications requiring instant finality and low-latency interactions.
Technical Advantages
Dual Consensus: Narwhal & Tusk
Sui employs a split consensus mechanism:
- Narwhal: A mempool protocol that efficiently collects and disseminates unconfirmed transactions.
- Tusk: An asynchronous consensus layer that orders transactions with minimal communication overhead.
By separating transaction submission from ordering, Sui reduces bottlenecks common in traditional BFT systems.
Parallel Transaction Execution
Sui classifies transactions into two types:
- Independent transactions (e.g., peer-to-peer transfers with no shared state) are executed in parallel.
- Dependent transactions (e.g., NFT auctions or smart contract calls) are processed sequentially.
This distinction allows Sui to maximize throughput—simple operations like Alice sending coins to Bob don’t wait behind complex smart contract logic.

Tokenomics: Stability Over Volatility
Sui’s economic model is designed for predictability:
- Total supply: 10 billion tokens, with partial circulation at mainnet launch.
- Gas fees are decoupled from storage costs: Users pay separate fees for computation (gas) and data storage.
- Unused stored data can be deleted to earn rebates, incentivizing efficient use of network resources.
- Storage fees go into a storage fund, which compensates validators for long-term data retention costs.
Crucially, Sui maintains stable gas pricing:
- Each epoch (24 hours), validators vote on a reference gas price based on prior usage.
- During traffic spikes, validator capacity scales linearly to absorb demand without spiking fees.
- This results in predictable transaction costs—even during high congestion.
Sui launched its testnet in August 2025 with an incentivized program underway, positioning it as a strong competitor in the high-performance L1 race.
Linera: Early-Stage Innovation with Rust-Based Design
Compared to its peers, Linera remains in early development. It secured $6 million in seed funding from a16z in June 2022 and is building quietly with a team comprising ex-Meta (Diem/Novi) and Zcash engineers.
Unlike Aptos and Sui, Linera has not confirmed use of the Move language. Instead, it emphasizes development using a Rust-based framework, suggesting possible similarities in safety and concurrency principles without full Move integration.
While public details are limited, Linera aims to deliver a lightweight, horizontally scalable blockchain optimized for microtransactions and social applications. Its delayed start means lower visibility today—but early technical signals suggest it could offer novel approaches to cross-chain interoperability and user onboarding.
