DoubleZero

DoubleZero is a network of dedicated fibre links for blockchains, starting with Solana; 2Z pays for access and rewards link providers.

DoubleZero is a network of private fibre links contributed by independent providers. It gives blockchain validators and other distributed systems a faster, more predictable path than the public internet. Solana was the first blockchain to use it, and validators holding about half of Solana's stake publish to its feed.

2Z is the network's token, an SPL token on Solana. Users pay for network access in 2Z, and contributors earn 2Z only when their links outperform the public internet. Part of each epoch's revenue is burned. Staking 2Z is planned but not yet live. Holders have no rights to dividends, profits or votes.

There were 10 billion 2Z at launch in October 2025. The Foundation holds 29% unlocked; Jump Crypto (28%), Malbec Labs (14%), institutions (12%) and the team (10%) unlock gradually over four years. Days before launch the SEC issued a no-action letter on 2Z's programmatic distribution.

DoubleZero also runs Edge, a low-latency market-data service that streams order books from venues such as Kalshi and Hyperliquid to trading firms.
