DoubleZero is a decentralized high-performance fiber network built for distributed systems: independent contributors supply private fiber links between datacenters, and validators, RPC operators, and data subscribers use them for lower-latency block propagation and market-data delivery. It starts with Solana, replacing public-internet hops with dedicated links coordinated by onchain programs.[1]
Quick verdict
Solana validators and RPC operators in connected metros gain the most from DoubleZero: its IBRL overlay keeps their public IP with no client restart while dedicated fiber and multicast cut propagation latency. The decisive constraint is operational weight: joining needs a Linux host with a public IP and firewall work, and contributing bandwidth needs datacenter hardware, so non-technical teams should choose managed RPC such as Pocket Network instead.[1][2][3]
Key features
IBRL overlay without client restart IBRL overlay keeps the validator's public IP: traffic is encapsulated through the DoubleZero device while the outside world still sees the node's own address, and connecting does not require restarting the Agave or Jito client.[1]
Private fiber that skips the public internet Dedicated links bypass the public internet: contributor fiber carries packets between cities instead of congested public routes, cutting latency and jitter for time-sensitive traffic.[1]
Multicast to many destinations at once Multicast delivery to many destinations at once: one packet stream fans out to every subscriber, which fits block propagation and market-data feeds better than repeated unicast sends.[1][2]
Permissionless access, no special hardware Permissionless user access with no special hardware: validators and subscribers join through software tunnels on ordinary servers, contributing nothing physical to consume the network.[1]
Verifiable routing and location proofs Onchain service-legibility: Edge devices emit eBPF proofs of the route each packet took plus geolocation proofs, so delivery claims are verifiable rather than marketing.[1]
Paid Edge feeds for Solana and market data Edge low-latency data feeds: Solana validator feeds and Kalshi market data ride the fabric as paid multicast streams for subscribers in connected metros.[1]
Contributors earn, users send packets Two-sided architecture: contributors add links and devices and earn from usage, while validators, RPC operators, and apps send packets; both sides are coordinated by Solana programs such as the serviceability and exchange contracts.[1]
Open-source client, separate testnet Open client with separate deployments: the protocol client is open source under Apache-2.0 with Linux packages, and the testnet and mainnet-beta networks are physically separate, so experimentation stays off production paths.[1]
Who will love it
Solana validators and RPC operators in connected metros: the IBRL overlay and multicast shred delivery directly target their latency bottleneck with no client restart.[1][2]
Teams with datacenter fiber and switching capacity: contributing links turns idle backbone capacity into paid network supply coordinated onchain.[1][2]
Trading and data teams needing fast Solana or event feeds: Edge multicast streams deliver validator and Kalshi data with lower latency than public-internet polling.[1]
Who should avoid it
Operators without Linux networking capacity: joining needs an x86_64 Linux host with a public IP, root access, and firewall tunnel rules, installed on the host rather than in a container.[1][2]
Users outside covered metros or chains: benefits depend on fabric presence in your cities, the rollout starts with Solana, and onboarding has passed through allowlisted-pubkey signup windows.[1][2]
Non-technical teams wanting managed RPC: DoubleZero is raw transport you operate yourself, so teams needing onboarding and support should prefer a managed provider such as Pocket Network.[1][2]
Fit and alternatives
Solana Agave and Jito validator clients run unchanged under the IBRL tunnel, so existing staking operations keep their software and keys.[1]
Wallets, indexers, and trading apps consume Edge multicast feeds where low-latency Solana and market data improves their product.[1][2]
Pocket Network is the incumbent in the published catalogue relationship and the honest redirect for teams that need managed RPC infrastructure instead of self-operated transport.[1]
Questions worth asking
What is the best DoubleZero alternative for non-technical users?
Pocket Network, the incumbent in this catalogue relationship, is the safer pick because it offers managed RPC infrastructure with ordinary onboarding, while DoubleZero assumes you operate a Linux server and join a fiber overlay.[1]
Is DoubleZero really no-code?
How much does DoubleZero cost per month?
Validators pay a share of block rewards each epoch for network access, and Edge feeds are prepaid per city and seat with funds held in wallet-controlled escrow. There is no flat monthly SaaS price; your cost is epoch fees or seat prepayments plus your own server and bandwidth costs. Checked October 9, 2026.[1]
Can you self-host DoubleZero?
Partly. The protocol client is open source under Apache-2.0 and runs on your own Linux host, but it connects to the shared DoubleZero fabric rather than a private network, and onboarding currently passes an allowlisted-pubkey signup. Contributing links is heavier: datacenter space, compatible hardware, and an onchain contributor account.[1][2]
