Every blockchain has a bottleneck that software alone cannot solve.
Validators across Ethereum, Solana, Celestia, and every other high-performance blockchain spend hours every year waiting for blocks and messages to cross congested networks built for resilience rather than speed. The public internet was designed for general use, for video streaming, email, social media, and billions of simultaneous connections across the globe. It routes traffic based on carrier economics, not performance, and shares bandwidth with streaming services and advertising delivery.
For blockchain validators who need millisecond-precise communication to participate in consensus, sign blocks, and propagate transactions, the public internet introduces exactly the kind of unpredictable latency and jitter that reduces network efficiency and limits throughput. The validators themselves have become significantly faster through improved software and hardware. The physical network connecting them has not kept pace.
DoubleZero was built to solve this specifically. Not through a new blockchain or a new smart contract platform but through an N1 protocol that operates beneath Layer 1 blockchains, rebuilding the physical connectivity layer through a decentralized network of contributed fiber-optic links, FPGA hardware devices, and edge filtering that removes spam before it reaches validators.
The project was built by Austin Federa, a former head of strategy at the Solana Foundation, alongside Jump Crypto, the digital assets subsidiary of Jump Trading, and Malbec Labs. It raised $28 million in a seed round led by Multicoin Capital and Dragonfly Capital in March 2025, followed by a validator sale in April 2025 at a $750 million FDV. The mainnet beta launched on October 2, 2025, with nearly 22% of all staked SOL connected via its infrastructure.
For Muslim investors, DoubleZero presents an unusual compliance profile. The core infrastructure concept is genuinely innovative and the service-based economic model is among the most defensible in our DePIN analysis series. The tokenomics and governance picture, however, are among the most seriously concerning in our analysis series, with the worst tokenomics fairness score we have assigned to any project that passes the compliance threshold.
We ran 2Z through the full CoinStudy Halal Crypto Standard (HCS) methodology with comprehensive research into all 2026 developments. Here is the complete picture.
DoubleZero passes the CoinStudy HCS Sharia red-line screening with no violations. It scores 72 out of 100 and is classified as Halal With Concerns.
The technology is genuinely innovative. The service-based economic model where contributors earn only for demonstrated performance is among the most Islamically defensible token utility models CoinStudy has assessed. But the tokenomics concentration with Jump Crypto holding 28% and Foundation and Ecosystem holding 29%, alongside documented market dumping by Jump Crypto shortly after launch, creates one of the most serious investor fairness concerns in our entire analysis library. The MEV relay user base and HFT-oriented DoubleZero Edge platform also require specific engagement.
DoubleZero is a decentralized physical infrastructure network, commonly described as a DePIN project, that provides dedicated high-speed fiber connectivity for blockchain validators and distributed systems through an N1 protocol operating beneath Layer 1 blockchains.
The protocol describes its core innovation as the separation of the physical network layer from blockchain execution. While blockchains operate at Layer 1 and above, DoubleZero operates at what it calls N1, the network layer beneath blockchains, coordinating dedicated fiber links and specialized FPGA hardware devices to create a private internet specifically optimized for decentralized system communication.
The 2Z token is the network's native utility asset. Users including blockchains, validators, RPC services, and MEV relays pay 2Z to access the network's dedicated connectivity. Network contributors who provide fiber optic links and related hardware earn 2Z based on their performance and usage. Future staking mechanisms are planned to bolster network security.
Importantly, the project's own disclosure states explicitly: "2Z is not and should not be viewed as an investment." Token holders have no rights to dividends, payments, profit sharing, distributions, or voting rights. This framing attempts to position 2Z as purely a utility access token rather than an investment vehicle.
Understanding what DoubleZero actually builds is essential for the compliance assessment because the compliance profile follows directly from what the service is and who pays for it.
The network architecture uses two rings. The outer ring sits at the boundary between the public internet and DoubleZero's private network. Specialized devices equipped with FPGAs handle inbound connections, mitigate DDoS attacks, verify transaction signatures, and filter spam or duplicate packets before they reach the inner network. This edge filtering removes the computational burden of spam processing from validators, freeing their CPU resources for genuine block production.
The inner data flow ring relays cleaned traffic over optimally routed dedicated bandwidth lines for consensus. Traffic moves over fiber links where routing is explicitly optimized for performance rather than carrier economics, achieving latencies and jitter levels that the public internet cannot consistently provide.
The economic model rewards this service directly. Contributors who provide fiber links earn 2Z tokens based on their link's performance and the usage demand for their specific routes. If a contributor's fiber link provides lower latency than the public internet for a demanded route, they earn. If it does not improve on the public internet, they earn nothing. This performance-linked model attempts to avoid the typical DePIN problem of overpaying for supply that nobody uses.
DoubleZero Edge, launched in Q2 2026, extends this infrastructure to a new use case: delivering real-time raw Solana blockchain data to institutional traders over the private fiber network using multicast technology. Validators earn fees for supplying data, and traders pay for subscriptions in USDC. This allows high-frequency trading firms to receive market data tens of milliseconds faster than through the public internet.
This section requires direct and honest engagement because it is the most nuanced compliance consideration in this analysis and one that Muslim investors deserve to understand clearly.
DoubleZero explicitly identifies MEV relays as users of its network alongside blockchains, validators, and RPC services. MEV, which stands for Maximal Extractable Value, refers to the additional profit that block producers can capture by controlling the ordering of transactions within blocks.
Some forms of MEV are permissible arbitrage that corrects price discrepancies across markets and improves overall market efficiency. These represent genuine productive economic service.
Other forms of MEV involve practices that Islamic finance would view critically including sandwich attacks, where bots detect pending large trades and insert their own transactions before and after to extract value from the original trader's price impact, and front-running, where prior knowledge of pending transactions is used to execute ahead of those transactions for profit at the original trader's expense. These extractive MEV strategies represent zero-sum financial activity where one party's gain comes directly from another party's financial harm through information asymmetry.
DoubleZero's whitepaper explicitly describes MEV as a beneficial user category: "MEV systems that relay proposals to validators quickly can use the extra time to find better orderings. MEV systems benefit from faster data retrieval and quicker delivery of blocks or bundles to the current leader."
The protocol does not distinguish between permissible arbitrage MEV and extractive sandwich attack or front-running MEV in its user base description. It treats all MEV relay activity as a legitimate use case for its infrastructure.
DoubleZero Edge specifically targets institutional trading firms including high-frequency traders with the explicit purpose of giving them faster access to Solana market data than other participants have. DoubleZero's co-founder Austin Federa acknowledged to Fortune that the project was explicitly inspired by high-frequency trading firms' private network infrastructure.
From an Islamic finance perspective, infrastructure that specifically enables and accelerates MEV strategies including extractive forms raises concerns under the principle of not facilitating harm to others. However the infrastructure neutrality principle applies here as well. DoubleZero provides connectivity infrastructure. What specific users do with that connectivity is their choice. The same fiber-optic network can serve a permissible arbitrage bot, a prohibited sandwich attack bot, or a legitimate validator.
CoinStudy's assessment is that providing neutral connectivity infrastructure that incidentally benefits MEV users alongside validators and RPC services does not independently trigger a red-line failure. The infrastructure neutrality principle protects DoubleZero at the protocol level. However the explicit marketing of DoubleZero Edge as enabling institutional traders to gain speed advantages over ordinary market participants raises fairness concerns from an Islamic perspective that are honestly reflected in the Underlying Business Activity score deduction.
The Tokenomics Fairness score of 3 out of 10 is the lowest in our analysis series for any project that passes the Halal compliance threshold. This requires the most direct and honest treatment in this analysis.
The total 2Z supply is 10 billion tokens. The distribution as disclosed is Foundation and Ecosystem approximately 29%, Jump Crypto approximately 28%, Malbec Labs approximately 14%, Team approximately 10%, with the remaining allocated to Institutions, Contributors, Builders, and Validators.
Jump Crypto and Malbec Labs together hold approximately 42% of total supply. The Foundation and Ecosystem hold another 29%. Insider-connected entities control approximately 71% of all 2Z tokens.
The community backlash following the October 2, 2025 launch was immediate and significant. Tokenomics documentation showed that the Foundation and Ecosystem tokens were unlocked at launch with no vesting. Jump Crypto moved over $20 million in 2Z tokens to exchanges within days of the mainnet launch. The 2Z price fell 40% from its initial surge within a short period.
The community criticism was specific and substantive: the project allocated tokens almost entirely to VCs and insiders without any meaningful community distribution. Ordinary users who participated in the testnet, supported the ecosystem, or wanted to use the network had minimal allocation compared to Jump Crypto's 28% and Malbec Labs' 14%.
The disclosure of the Foundation tokens being unlocked without vesting while claiming they are "not circulating" because they have not moved created a specific transparency concern. Foundation holdings that can be moved at any time without vesting restrictions create an overhang that ordinary token holders cannot protect themselves against.
The full unlock schedule extends to 2029, meaning ongoing supply pressure from insider unlocks will continue for years. The next major unlock is scheduled for October 2, 2026, releasing Builders' allocation.
From an Islamic finance perspective, this tokenomics structure creates the kind of insider advantage and information asymmetry that Islamic commercial ethics identifies as problematic. Early investors and the engineering firms behind the project received tokens at prices far below what public market participants paid. The rapid post-launch selling by Jump Crypto, which moved $20 million to exchanges within days of the token going live, directly harmed participants who bought at launch prices based on the project's institutional backing.
DoubleZero received a No-Action Letter from the US Securities and Exchange Commission, allowing the team to sell 2Z tokens in the United States without facing immediate enforcement action. This was described as a regulatory milestone for the blockchain infrastructure project.
From an Islamic finance perspective, regulatory authorization in the US regulatory framework does not determine Sharia compliance. However the No-Action Letter is compliance-relevant in two specific ways.
First, it reflects the SEC's assessment that 2Z is sufficiently utility-driven that it can be treated as a utility token rather than a security. This assessment, while made under US securities law rather than Islamic finance principles, aligns with CoinStudy's assessment that the 2Z token's core economic model is based on genuine service utility rather than on investment return expectations.
Second, the No-Action Letter ironically failed to boost token confidence because the community's concern was not regulatory status but tokenomics concentration. Regulatory clarity about what a token is does not address fairness concerns about how it was distributed.
Grayscale added DoubleZero to its Q1 2026 "Assets Under Consideration" watchlist in the Utilities and Services category in January 2026, providing institutional credibility signal and a 10% price surge.
The DoubleZero Delegation Program Phase 2 launched on March 9, 2026, extending structured staking incentives to encourage 2Z holders to delegate their tokens to network validators, reducing circulating supply while increasing staking ratios.
DoubleZero Edge launched in April 2026 as a permissionless multicast-enabled market data distribution platform delivering real-time Solana blockchain data to institutional traders over the dedicated fiber network. Validators earn fees for data provision, traders pay subscriptions in USDC.
Smart contract SDK releases in Rust and Solidity bindings were completed in Q1 2026, allowing developers to build applications that leverage DoubleZero's connectivity.
The Q2 2026 "Mainnet Stable" designation with institutional validator onboarding has been completed, advancing the network from beta to more mature operational status.
Multi-chain expansion beyond Solana to support Celestia, Sui, Aptos, Avalanche, and other high-performance blockchains is planned for the medium term.
DoubleZero's core economic model is one of the most service-based in our DePIN analysis series. Contributors earn 2Z because they provided fiber connectivity that demonstrably reduced latency compared to the public internet on routes with actual demand. Users pay 2Z because they received that connectivity service. No interest mechanism, no lending relationship, and no predetermined percentage return on deposited capital exists at any level of the core protocol.
The Financial Exposure Risk score of 22 out of 25 reflects this clean service economy alongside deductions for the MEV relay user base and DoubleZero Edge's specific positioning to enable institutional speed advantages over ordinary market participants, creating an indirect association with extractive financial activity.
The Gharar score of 11 out of 15 reflects genuine uncertainty from multiple dimensions. The physical infrastructure model of coordinating contributed fiber links across global contributors creates more implementation complexity and verification challenge than software-only protocols. Whether performance-based contributor rewards will accurately measure and compensate genuine service quality at scale is unproven. The competitive landscape against telecom operators with vastly more fiber infrastructure resources creates genuine adoption uncertainty.
DoubleZero was built to solve a genuine infrastructure problem in distributed systems. The core purpose is neither speculative nor gambling-adjacent.
The Maysir score of 10 out of 15 reflects this genuine infrastructure purpose alongside the specific concern about DoubleZero Edge's explicit positioning to give institutional HFT firms speed advantages over other market participants. Accelerating high-frequency trading strategies that extract value through speed asymmetry against ordinary traders is not genuinely productive economic activity in the Islamic finance sense. The edge infrastructure serving MEV relays for extractive strategies compounds this concern.
Blockchain connectivity infrastructure that enables validators to communicate more efficiently, reduces DDoS vulnerability, and improves network performance is genuinely permissible and valuable economic activity. The infrastructure neutrality of the core fiber network earns a strong base score.
The Underlying Business Activity score of 13 out of 15 reflects this permissible infrastructure purpose alongside deductions for DoubleZero Edge's explicit market positioning for HFT speed advantages and the project's active facilitation and marketing of MEV relay usage as a primary user category.
Nearly 22% of all staked SOL connected at mainnet beta launch, Grayscale institutional consideration, the Q2 2026 mainnet stable designation, and the DoubleZero Edge institutional data platform all demonstrate genuine real-world deployment beyond speculative interest.
The Utility and Real Use score of 9 out of 10 reflects this genuine utility alongside the limitation that primary demonstrated adoption is from HFT and institutional trading applications rather than from the validator coordination and distributed system efficiency use cases that represent the most clearly permissible economic activity.

DoubleZero is scored across 7 Shariah principles with a total of 100 points.
On Financial Exposure Risk, weighted at 25%, 2Z scores 22 out of 25. Clean service-based core economy. Deductions for MEV relay user base and DoubleZero Edge positioning for institutional trading speed advantages.
On Gharar, weighted at 15%, 2Z scores 11 out of 15. Physical infrastructure complexity, unproven performance measurement at scale, and competitive positioning against telecommunications operators all create meaningful uncertainty.
On Maysir, weighted at 15%, 2Z scores 10 out of 15. Genuine infrastructure purpose. Deductions for HFT positioning through DoubleZero Edge and MEV relay facilitation.
On Underlying Business Activity, weighted at 15%, 2Z scores 13 out of 15. Blockchain connectivity infrastructure is permissible. Deductions for HFT speed advantage positioning and MEV facilitation.
On Utility and Real Use, weighted at 10%, 2Z scores 9 out of 10. 22% of staked SOL at launch, institutional validator onboarding, mainnet stable designation, and Grayscale consideration all demonstrate genuine deployment. Small deduction for HFT-dominated adoption profile.
On Tokenomics Fairness, weighted at 10%, 2Z scores 3 out of 10. The lowest tokenomics score in our analysis series for a project that passes the compliance threshold. Jump Crypto 28% plus Malbec Labs 14% plus insider-connected Foundation 29% equals approximately 71% of total supply in insider-connected hands. Jump Crypto moved $20 million to exchanges within days of launch causing a 40% price decline for public buyers. No meaningful community allocation for testnet participants or ecosystem contributors. Foundation tokens unlocked without vesting at launch.
On Transparency and Governance, weighted at 10%, 2Z scores 4 out of 10. The tokenomics disclosure's treatment of unlocked but unmoved Foundation tokens as potentially not circulating created specific transparency concerns. The explicit disclaimers in the tokenomics documentation that "token holders do not have any rights with respect to dividends, payments, profit sharing, distributions, or voting rights" reflect both regulatory caution and significant governance limitations for ordinary 2Z holders.
Overall HCS Score: 72 out of 100 — Halal With Concerns
Muslim investors evaluating DePIN infrastructure projects now have several options in our analysis series.
Filecoin (FIL) scores 89 out of 100 Halal. Decentralized data storage with cryptographic proof verification, institutional clients including the Internet Archive and Smithsonian, and a fair launch model. The clearest compliance profile in the DePIN category.
Render Network (RENDER) scores 88 out of 100 Halal. GPU computing services for rendering, AI inference, and visual effects. Service-based economy with real adoption by professional creative and AI users.
DoubleZero (2Z) scores 72 out of 100 Halal With Concerns. The most technically innovative connectivity infrastructure in our DePIN series. The most serious tokenomics fairness concerns in our DePIN series. The core service concept is permissible. The distribution was deeply unfair to public participants.
The gap between DoubleZero at 72 and Render and Filecoin at 88-89 reflects primarily the tokenomics catastrophe rather than technology or business activity differences. If DoubleZero had distributed tokens fairly with meaningful community allocation and without insider dumping, the score would be meaningfully higher.
Before investing in DoubleZero, ask yourself honestly.
Do I understand that Jump Crypto holds approximately 28% of all 2Z supply and moved $20 million to exchanges within days of the token launch, causing a 40% price decline for public buyers? Do I understand that Foundation and Ecosystem tokens at approximately 29% of supply were unlocked at launch without vesting, creating an ongoing token overhang that can be moved at any time? Am I aware that DoubleZero explicitly serves MEV relays as a primary user category and that DoubleZero Edge is specifically positioned to give institutional HFT firms speed advantages over ordinary market participants? Do I understand the difference between DoubleZero's core validator connectivity infrastructure, which has a more defensible compliance profile, and DoubleZero Edge's HFT data service, which raises more significant Islamic ethics questions? Am I investing based on conviction in the fiber-optic blockchain connectivity thesis with full awareness of the tokenomics risks, or following the institutional backing narrative without understanding what happened to public token buyers at launch?
DoubleZero (2Z) is classified as Halal With Concerns under the CoinStudy Halal Crypto Standard with a score of 72 out of 100.
The core infrastructure concept is among the most genuinely innovative and service-based in our DePIN analysis series. A fiber-optic network providing performance-based connectivity rewards where contributors earn only for demonstrably better service than the public internet represents one of the most defensible DePIN economic models CoinStudy has assessed. The technology solves a genuine bottleneck. The validator connectivity service creates genuine value.
The tokenomics picture is among the worst we have encountered for any project that passes the compliance threshold. Jump Crypto's 28% allocation combined with Malbec Labs' 14% and an unlocked Foundation holding of 29% created a situation where approximately 71% of supply was in insider-connected hands at launch. Jump Crypto's documented movement of $20 million in tokens to exchanges within days of the mainnet launch, causing a 40% price decline for public buyers, represents a specific and documented harm to ordinary investors that Islamic commercial ethics cannot overlook.
The MEV relay and HFT positioning create secondary compliance concerns that moderate the underlying business activity score without triggering independent red-line failures.
Muslim investors who want exposure to DePIN infrastructure with stronger tokenomics fairness profiles should consider Filecoin or Render Network, both of which score significantly higher and have cleaner distribution histories. Muslim investors who specifically want DoubleZero's unique fiber-optic blockchain connectivity exposure should do so with full awareness that the 3 out of 10 tokenomics score reflects genuinely serious fairness concerns that ongoing price performance may not resolve.
