DoubleZero

What is DoubleZero (2Z)?

DoubleZero is a decentralized network that aims to move data faster between blockchain participants. It was developed by Malbec Labs, and its mainnet-beta and the 2Z token began public operation on 2 October 2025. The initial network works with Solana validators, RPC providers and MEV infrastructure providers.

The project describes a shared mesh built from spare capacity, such as underused private fiber links and hardware like switches. Contributors supply this capacity, and the network joins it together using the DoubleZero protocol. In return they receive token incentives.

How DoubleZero works

Blockchains depend on fast, consistent communication between nodes. DoubleZero routes traffic over its own optimized links instead of the public internet, which is meant to reduce latency and jitter.

• Contributors provide fiber and hardware to the network.
• Users, such as validator clients and RPC providers, connect through admission control that checks their public keys.
• Planned features include filtering spam and duplicate transactions at the network edge, which the documentation describes as not yet functional.

2Z supply and token design

2Z is the incentive token of the network, and the maximum supply is 10,000,000,000 tokens. Tokens are allocated across several groups, including the DoubleZero Foundation and Malbec Labs, and part of the supply vests over time. Live circulating supply is shown in the market data on this page.

2Z is a Solana token, at mint address J6pQQ3FAcJQeWPPGppWRb4nM8jU3wLyYbRrLh7feMfvd. Check the mint address before trading, because lookalike tokens are common on Solana.

Official information is on doublezero.xyz.

The documentation positions DoubleZero as infrastructure that sits beneath applications rather than as a consumer product. Its first users are on Solana, in two areas called IBRL and Edge, and validator rewards are part of the design. A whitepaper on the project site sets out the protocol in more depth for readers who want the technical detail.

What to check before using 2Z

• The network is young, and several features are still described as planned rather than live.
• Its value depends on validators and infrastructure providers adopting it, and on enough contributors supplying capacity.
• Vesting schedules mean more tokens can reach the market over time.
• Admission control limits who can use the network, so access is not open to everyone.
• Fake tokens with the same name exist on Solana, so verify the mint address.
