What is DoubleZero (2Z)?

Deep Dive

1. Purpose & Value Proposition

DoubleZero addresses critical inefficiencies in public internet infrastructure for blockchain systems. Validators and RPC nodes face unpredictable latency, congestion, and packet loss when transmitting data across shared networks. By creating a dedicated physical layer using underutilized global fiber, DoubleZero reduces Solana validator skipped slots by 0.35 percentage points and enables near-instant communication for high-performance chains. This is particularly valuable for consensus mechanisms where milliseconds impact transaction finality and validator rewards.

2. Technology & Architecture

The network operates as a decentralized mesh of privately contributed fiber links, forming direct point-to-point connections between blockchain nodes. Key innovations include:
- Edge Filtration: Specialized hardware (DZD devices) filters spam traffic at the source, ensuring clean data transmission.
- Multicast Routing: Simultaneously broadcasts data to multiple nodes, reducing redundant transmissions.
- IBRL Mode: A proprietary protocol minimizing latency by optimizing packet paths in real-time.
Contributors provide bandwidth via their infrastructure, while validators access this private network instead of the public internet.

3. Tokenomics & Governance

The 2Z token (SPL standard on Solana) powers three core functions:
- Network Access: Validators pay 2Z to utilize high-speed routes.
- Contributor Rewards: Bandwidth providers earn 2Z based on usage and performance metrics.
- Security: Staking 2Z via dzSOL contracts helps secure the network.
Tokenomics feature a 10B fixed supply with controlled inflation for rewards and burns to deter spam, aiming for long-term supply equilibrium.

Conclusion

DoubleZero fundamentally reimagines internet infrastructure for decentralized systems, using token-incentivized physical networks to replace legacy routing with a purpose-built, high-speed alternative. How might this model expand to support latency-sensitive applications beyond blockchain?
