Introduction
The blockchain landscape continues to evolve with innovative projects emerging from Meta's former Diem and Novi teams. Three standout networks—Aptos, Sui, and Linera—are gaining attention for their technical advancements and unique approaches to solving blockchain's scalability challenges. This guide examines their key features, technological foundations, and market potential.
The Meta Connection: A Shared Heritage
These projects share DNA through their founders' involvement in:
- Diem: Meta's abandoned stablecoin project (originally Libra)
- Novi: The company's discontinued digital wallet initiative
After Meta dissolved these ventures in 2022, team members launched independent blockchain solutions leveraging their expertise in distributed systems and digital assets.
Aptos: The Parallel Processing Powerhouse
Funding and Backing
- $350 million raised across two rounds (a16z, Multicoin, FTX Ventures)
- Strategic investments from Binance Labs
Technical Innovations
Move Language Architecture
- Resource-oriented programming model
Built-in protections against:
- Token duplication
- Unauthorized transfers
- Phantom balance issues
- Static contract analysis reduces runtime errors
Block-STM Parallel Execution
- Processes transactions concurrently
- Achieves high TPS without strict node synchronization
- Allows inactive nodes to participate in state sync
Flexible Gas Payments
- Users can pay fees in non-native tokens
Current Status
- Testnet incentive program underway
- Mainnet launch planned for September 2023
Sui: The Scalability Specialist
Development Team
- Created by Mysten Labs (ex-Meta/Diem engineers)
- $176 million total funding (a16z, FTX-led rounds)
Core Advancements
1. Optimized BFT Consensus
Tusk/Narwhal hybrid protocol:
- Independent transactions: Parallel processing
- Dependent transactions: Ordered execution
2. Novel Token Economics
Dual-Fee Structure:
Fee Type Purpose Destination Gas Fee Transaction processing Validators Storage Fee Data persistence Storage fund Stable Gas Mechanism:
- Epoch-based (24-hour cycles)
- Linear scaling during demand spikes
- Price predictability within ±10% of reference
Roadmap
- Testnet launch August 2023
- Incentivized testnet program coming soon
Linera: The Emerging Contender
Current Status
- Early development phase
- $6 million seed round (a16z-led)
Technical Direction
- Rust-based language (Move-inspired but not identical)
- Team includes former Zcash developers
- Details remain scarce pending further announcements
Comparative Analysis
| Feature | Aptos | Sui | Linera |
|---|---|---|---|
| Language | Move | Move | Rust-based |
| Consensus | Block-STM | Tusk/Narwhal | TBA |
| TPS Focus | Parallel exec | Transaction classification | Unknown |
| Funding | $350M | $176M | $6M |
Key Challenges and Opportunities
Adoption Barriers
- Developer Onboarding: Move requires learning new paradigms vs. Solidity's established ecosystem
- EVM Compatibility: Lack of native EVM support may limit DeFi migration
Market Potential
- Strong investor overlap with Solana's backers
- Aptos leads in community growth; Sui shows strong technical differentiation
- Linera's late start positions it as a dark horse candidate
FAQs
Q: Why are these called "Meta chains"?
A: The projects share founding teams from Meta's blockchain initiatives (Diem/Novi), though they operate independently.
Q: Which chain has the best token economics?
A: Sui's dual-fee model and gas stabilization mechanisms currently offer the most innovative design.
Q: When will these networks go live?
A: Aptos plans September 2023 mainnet; Sui aims for late 2023; Linera hasn't announced timelines.
Q: Can Ethereum dApps easily migrate to these chains?
A: Not directly—Move language differences require substantial code rewrites versus EVM-compatible chains.

Conclusion
The Meta-alumni chains demonstrate how technical rigor from large tech projects can translate into blockchain innovation. While Aptos currently leads in funding and visibility, Sui's novel consensus and fee structures present compelling alternatives. Linera remains an intriguing wildcard. As these networks mature through 2023, their ability to attract developers while maintaining security will determine whether they become enduring players or cautionary tales in the competitive L1 landscape.
