DoubleZero: Rewiring Blockchain Networking - What You Need to Know
Fiber-optic Links, Jump‑backed network, $10B FDV Launch, and More
Bandwidth is often the bottleneck of blockchains. Every year validators spend hours waiting for blocks and messages to cross congested networks built for resilience rather than speed. DoubleZero aims to solve this by creating a global “new internet” optimized for distributed systems using dedicated fiber links, hardware devices, and edge filtering to reduce latency and jitter.
In this edition, we’ll cover what DoubleZero’s network does, how the network’s architecture and devices work, and the launch of $2Z.

Primer: What is DoubleZero
DoubleZero is a product created by Jump and Malbec Labs (core contributor) and is backed by Multicoin, Dragonfly, Superscrypt, and many more. In March 2025 it raised $28 million at a $400 million FDV, followed by a validator sale in April at a $750 million FDV. When the token launched on 2 October 2025, $2Z hit upwards of $1.20 per token across major exchanges, implying a $12 billion FDV. This figure is more than 25× the private-round valuation.
Traditional public networks route traffic based on cost and resilience, not performance; this introduces unpredictable latency and jitter. For blockchains this means longer time to finality, propagation delays and increased risk of MEV instability.
Remedies such as centralized mempools reduce the ingestion burden but introduce extra latency and broadcast transaction intent to potential front‑runners. Stake‑weighted quality‑of‑service systems prioritize capitalized actors but still add latency and exclude smaller participants. Using DoubleZero, traffic enters through hardware filters that remove junk, then uses fiber links where routes are explicitly optimized. This allows validators to spend CPU resources on executing transactions rather than sifting through spam.
Double Zero Architecture
The DoubleZero network is conceptualized as two rings where the outer ring sits at the boundary between the public internet and DoubleZero. Specialized network devices equipped with field‑programmable gate arrays (FPGAs) handle inbound connections that mitigate DDoS attacks, verify transaction signatures and filter spam or duplicate packets.
By off‑loading these tasks to dedicated hardware, the system ensures that validators CPU processing focuses solely on block production. Once traffic has been cleaned, it moves to the inner data flow ring, where it is relayed over optimally routed, dedicated bandwidth lines for consensus.
This two‑ring design separates the resource‑intensive filtration step from consensus and allows the network to approach the maximum throughput that physics permits.
DoubleZero also proposes a dedicated layer that contributors build by offering underutilized fiber-optic links and programmable hardware. In return, contributors earn tokens proportional to their link’s performance. Users include blockchains, validators, RPC services and MEV relays who connect to DoubleZero to enjoy edge filtering (spam and duplicate removal) and optimized routing.
In essence, the core architecture can be summarized as such:
Edge filtering eliminates spam and duplicate packets before they reach validators, allowing nodes to allocate resources to block production rather than traffic filtering.
Optimized routing prioritizes outbound messages and routes them directly, reducing jitter and propagation times.
High‑performance mesh network built from dedicated fiber allows distributed systems to approach physical bandwidth limits, improving consensus speed.
$2Z Supply and distribution
DoubleZero’s tokenomics disclosure states that 10 billion 2Z tokens were minted at launch. Supply can change through inflation (minting new tokens to support computing and security) and burns (destroying tokens to ensure equitable distribution and discourage fraudulent traffic).
The Foundation’s 29 % of tokens is unlocked at launch, giving the foundation significant control over the circulating supply. Jump Crypto, the largest external contributor, holds 28 % of tokens, of which only 5 % is immediately unlocked.
It is unclear (with some allocations overlapping), how the allocations are differentiated between Contributors, Team, Jump, Foundation, etc. as they sound somewhat interlinked.
