DoubleZero (2Z)

What is DoubleZero

DoubleZero is a physical fiber network spanning the globe - using existing subsea and terrestrial fiber links contributed by a diverse set of network contributors. This physical fiber layer provides an alternative pathway for distributed systems to communicate over, one that is far more stable and predictable than the public internet.

Validators on high-performance blockchains such as Solana can be inundated with a flood of inbound transactions when building a block, reducing block-building efficiency and reducing rewards. One the validator has produced a block, it has to transmit that block out to thousands of other validators so consensus can be reached before the network can advance – and DoubleZero provides a faster, more efficient base layer for that communication.

DoubleZero enables validators to operate at maximum efficiency without massive infrastructure investments—a paradigm shift for blockchain networks where communication, not computation, has become the real bottleneck.
