{"id":"lium","title":"Lium","content":"**Lium** is a decentralized cloud computing platform and [peer-to-peer](https://iq.wiki/wiki/peer-to-peer-trading-p2p) marketplace for on-demand Graphics Processing Unit (GPU) resources. It operates as Subnet 51 (SN51) on the [Bittensor](https://iq.wiki/wiki/bittensor-tao) network, connecting providers of GPU hardware with users who require computational power for tasks such as artificial intelligence (AI) model training, inference, and rendering. The platform aims to provide a more accessible and cost-effective alternative to traditional centralized cloud providers by leveraging a distributed global network. [\\[1\\]](#cite-id-kjkVJWGC8lKPNxDC) [\\[2\\]](#cite-id-RgZeGmCrl3lgu4IG)​\n\n[YOUTUBE@VID](https://youtube.com/watch?v=X2zDrO_dXuY)\n\n## Overview\n\nLium functions as a two-sided marketplace built on the [Bittensor](https://iq.wiki/wiki/bittensor-tao) [blockchain](https://iq.wiki/wiki/blockchain). The supply side consists of \"Miners,\" who are individuals or data centers that connect their GPU hardware to Bittensor Subnet 51. In return for providing reliable and performant compute resources, they are rewarded with [TAO](https://iq.wiki/wiki/bittensor-tao), Bittensor's native token. The demand side consists of \"Renters,\" who are developers, researchers, and companies that rent these compute resources, packaged as \"Pods,\" on an hourly basis through the Lium web interface or Command-Line Interface ([CLI](https://iq.wiki/wiki/cli)). [\\[1\\]](#cite-id-kjkVJWGC8lKPNxDC) [\\[3\\]](#cite-id-YrggkBGkgn3sY4WI)​\n\nThe platform’s value proposition centers on providing GPU rentals at a significantly lower cost than centralized services like Amazon Web Services (AWS) and Microsoft Azure, with some sources claiming up to 90% in savings. It is designed to be permissionless, allowing anyone to participate as a provider or user without [Know Your Customer](https://iq.wiki/wiki/know-your-customer-kyc) (KYC) procedures, and facilitates payments through both traditional methods and [cryptocurrency](https://iq.wiki/wiki/cryptocurrency). [\\[2\\]](#cite-id-RgZeGmCrl3lgu4IG) [\\[4\\]](#cite-id-mIY44hfrUKozicp0)​\n\nWithin the [Bittensor](https://iq.wiki/wiki/bittensor-tao) ecosystem, Lium is positioned as a foundational infrastructure layer, often referred to as the \"compute backbone of Bittensor,\" providing the necessary computational power for other subnets to run AI models. The platform and its development are managed by the legal entity Datura AI Corp. [\\[5\\]](#cite-id-awsvfCJOhoB5LWlX) [\\[3\\]](#cite-id-YrggkBGkgn3sY4WI)​\n\n## History\n\nInitially named Celium, Lium officially launched on the [Bittensor](https://iq.wiki/wiki/bittensor-tao) network in late 2024. The project's official X (formerly Twitter) account was created on October 18, 2023, followed by a formal announcement as a decentralized GPU platform on December 20, 2023. [\\[2\\]](#cite-id-RgZeGmCrl3lgu4IG) [\\[3\\]](#cite-id-YrggkBGkgn3sY4WI)​\n\nThe platform saw rapid early development and adoption. Its web interface for browsing and renting GPUs was launched on January 10, 2024. Key features were added shortly after, including support for Confidential Virtual Machines (CVMs) on February 7, 2024, and a full REST API and Python SDK on February 28, 2024. In its first month of operation, the network onboarded approximately 500 NVIDIA H100 GPUs. [\\[3\\]](#cite-id-YrggkBGkgn3sY4WI) [\\[2\\]](#cite-id-RgZeGmCrl3lgu4IG)​\n\nBy 2025, Lium had established itself as one of the top-emitting subnets on [Bittensor](https://iq.wiki/wiki/bittensor-tao), accounting for approximately 6-7% of the network's total TAO emissions distributed as incentives. A significant milestone was reached after 2025 when the platform's revenue from direct GPU rentals began to exceed the value of its [blockchain](https://iq.wiki/wiki/blockchain)-based TAO incentives, indicating strong product-market fit and customer demand beyond the initial crypto-incentivized phase. [\\[2\\]](#cite-id-RgZeGmCrl3lgu4IG)​\n\nBy March 2024, Lium was a significant contributor to the collective 5.3 million annualized revenue run-rate. [\\[3\\]](#cite-id-YrggkBGkgn3sY4WI) [\\[6\\]](#cite-id-XfkWNo1lkX0SrdEH)​\n\n## Technology and Architecture\n\nLium is a full-stack platform built as an application layer on top of [Bittensor's](https://iq.wiki/wiki/bittensor-tao) Subnet 51. Its architecture is composed of a user-facing frontend suite and a decentralized backend infrastructure. [\\[2\\]](#cite-id-RgZeGmCrl3lgu4IG)​\n\n### Bittensor Integration\n\nThe platform is fundamentally integrated with the [Bittensor](https://iq.wiki/wiki/bittensor-tao) network, which provides the framework for its decentralized operations. It uses the Subtensor [blockchain](https://iq.wiki/wiki/blockchain) to manage trustless interactions, process payments, and log miner performance data. This ensures that the marketplace's rules are enforced by the protocol without a central authority. The core network operates through a system of network participants with distinct roles. [\\[2\\]](#cite-id-RgZeGmCrl3lgu4IG) [\\[3\\]](#cite-id-YrggkBGkgn3sY4WI)​\n\n* **Miners (Providers):** Individuals or data centers who connect their GPU servers to the network by running Lium's software. Their hardware is made available for rent and is continuously benchmarked.\n* **Validators:** Network nodes responsible for verifying the performance, reliability, and authenticity of the miners' hardware. They run benchmarks and audit miners to ensure they provide the compute they promise. Their collective consensus determines the allocation of TAO rewards.\n* **Renters (Users):** The end-users who purchase and utilize GPU compute power from the network for their workloads.\n\n### Trust and Incentive Mechanisms\n\nTo ensure service quality and reliability, Lium employs several crypto-economic mechanisms.\n\n#### TAO Rewards\n\nMiners are incentivized to provide high-quality hardware and maintain uptime through rewards paid in TAO. [Validators](https://iq.wiki/wiki/validator) also receive TAO for their role in auditing the network. The reward distribution is tiered, with higher-performing and more reliable miners earning a larger share of the emissions. [\\[3\\]](#cite-id-YrggkBGkgn3sY4WI) [\\[4\\]](#cite-id-mIY44hfrUKozicp0)​\n\n#### Collateral and Slashing\n\nA key trust mechanism is a collateral system implemented via [smart contracts](https://iq.wiki/wiki/smart-contract) on [Bittensor's](https://iq.wiki/wiki/bittensor-tao) [EVM](https://iq.wiki/wiki/ethereum-virtual-machine-evm) module. GPU providers (miners) are required to stake collateral in the form of TAO. If a rented GPU goes offline or fails to perform as specified, a portion of the miner's staked collateral is automatically forfeited or \"slashed.\" This creates a strong financial incentive for miners to provide dependable service, aiming for stability comparable to centralized providers. This system, however, has been noted as a potential centralization risk, as the collateral requirement could pose a high barrier to entry for smaller-scale operators. [\\[2\\]](#cite-id-RgZeGmCrl3lgu4IG) [\\[4\\]](#cite-id-mIY44hfrUKozicp0)​\n\n### Platform Features\n\n#### Confidential Computing\n\nLium offers support for Confidential Virtual Machines (CVMs), a feature designed for users with highly sensitive workloads. CVMs create a secure, encrypted environment where data and code remain confidential, even from the hardware provider. This is particularly useful for tasks involving proprietary AI model weights, private codebases, or confidential datasets. [\\[3\\]](#cite-id-YrggkBGkgn3sY4WI)​\n\n#### Developer Ecosystem\n\nThe platform provides a suite of tools for programmatic access and integration. This includes a comprehensive REST API for querying available machines and managing rentals, as well as an official Python SDK to simplify these interactions. A Command-Line Interface ([CLI](https://iq.wiki/wiki/cli)) is also available for developers to manage resources directly from their terminals. [\\[3\\]](#cite-id-YrggkBGkgn3sY4WI) [\\[1\\]](#cite-id-kjkVJWGC8lKPNxDC)​\n\n#### Hardware Support\n\nLium is designed to be hardware-agnostic, supporting a wide array of accelerators. This includes enterprise-grade NVIDIA GPUs like the A100, H100, H200, and B200 series; consumer-grade GPUs like the RTX 3090 and 4090; and accelerators from other manufacturers such as AMD and Intel. The platform also features custom-built modules for GPU scheduling and hardware abstraction, which are claimed to result in approximately 45% better utilization compared to traditional management methods. [\\[1\\]](#cite-id-kjkVJWGC8lKPNxDC) [\\[2\\]](#cite-id-RgZeGmCrl3lgu4IG)​\n\n## Marketplace and Adoption\n\nLium has established itself as a primary compute provider within the [Bittensor](https://iq.wiki/wiki/bittensor-tao) ecosystem. Its initial traction came from miners on other compute-intensive Bittensor subnets, such as Score, Templar, and [IOTA](https://iq.wiki/wiki/iota), who required powerful hardware for their own operations. Use cases for renters on the platform include AI model training, fine-tuning open-source models, text-to-video generation, and other custom AI workflows. [\\[6\\]](#cite-id-XfkWNo1lkX0SrdEH) [\\[4\\]](#cite-id-mIY44hfrUKozicp0)​\n\n### Hardware Inventory and Pricing\n\nThe Lium marketplace provides real-time visibility into the availability, specifications, and pricing of GPUs on the network. The platform features a deep inventory of high-end GPUs sought after for AI workloads. Analysis from Unsupervised Capital noted that Lium hosts a significantly larger pool of NVIDIA B200 GPUs than competing platforms like Vast.ai and sustains rental rates for them that are over 50% higher. At the same time, it has been reported to offer some of the lowest hourly rates available for NVIDIA H100 GPUs. [\\[6\\]](#cite-id-XfkWNo1lkX0SrdEH) [\\[1\\]](#cite-id-kjkVJWGC8lKPNxDC)​\n\nAs of early 2026, available hardware included single GPUs like the NVIDIA RTX 4090, A100-SXM4-80GB, and B200, as well as large cluster configurations such as 8x NVIDIA H200 and 8x NVIDIA B200. Nearly 85% of the platform's revenue was generated from the rental of high-end NVIDIA B200, H200, and A100 GPUs. [\\[1\\]](#cite-id-kjkVJWGC8lKPNxDC) [\\[6\\]](#cite-id-XfkWNo1lkX0SrdEH)​\n\n### Network Metrics\n\nAs of April 8, 2026, network statistics for Subnet 51 indicated 147 active miners and 21 active validators. The subnet had daily emissions of approximately 720 TAO and a total stake of 266,423 TAO. [\\[3\\]](#cite-id-YrggkBGkgn3sY4WI)​\n\n## Subnet Token (SN51)\n\nWhile Lium's primary incentive structure is based on [Bittensor's](https://iq.wiki/wiki/bittensor-tao) native token, TAO, it also incorporates its own subnet token, which uses the ticker SN51. This token functions within the internal economy of Subnet 51. Some sources state Lium has no native token, which typically means it does not have a standalone [cryptocurrency](https://iq.wiki/wiki/cryptocurrency) independent of the Bittensor ecosystem; its token exists only within the subnet framework. [\\[3\\]](#cite-id-YrggkBGkgn3sY4WI) [\\[7\\]](#cite-id-SiihVWGjl2yYOheH)​\n\n### Tokenomics\n\nLium's economic model includes mechanisms designed to support the value of its subnet token and, by extension, the incentives paid to compute providers. A portion of the revenue generated from GPU rentals is used to fund token buyback programs. In addition, the subnet has implemented a deflationary model. As of September 2025, this involved burning 60% of the daily miner emissions of the SN51 token. [\\[6\\]](#cite-id-XfkWNo1lkX0SrdEH) [\\[4\\]](#cite-id-mIY44hfrUKozicp0)​\n\n### Market Data\n\nAs of April 8, 2026, the SN51 token was ranked #323 on [CoinMarketCap](https://iq.wiki/wiki/coinmarketcap) with a [market capitalization](https://iq.wiki/wiki/market-capitalization) of approximately $59.6 million. The [circulating supply](https://iq.wiki/wiki/circulating-supply) was reported as 3,819,578 SN51 out of a maximum supply of 21,000,000. It was available for trading on exchanges such as [MEXC](https://iq.wiki/wiki/mexc) against [USDT](https://iq.wiki/wiki/tether) and on Subnet Tokens against TAO. [\\[7\\]](#cite-id-SiihVWGjl2yYOheH)​\n\nFor historical context, data from September 8, 2025, reported the SN51 token price at 50.4 million. At that time, Lium was the highest-earning subnet on the [Bittensor](https://iq.wiki/wiki/bittensor-tao) network with a monthly revenue rate of about $432,000. [\\[4\\]](#cite-id-mIY44hfrUKozicp0)​\n\n## Partnerships\n\nLium has a strategic partnership with DeSearch, [Bittensor's](https://iq.wiki/wiki/bittensor-tao) subnet for decentralized real-time search and data intelligence (SN22, formerly SN5). In this collaboration, Lium provides the underlying GPU compute infrastructure required for DeSearch to run and scale its AI-powered search models. The partnership enables a unified workflow for developers, allowing them to retrieve live data using DeSearch and process it with Lium's scalable GPU network within a fully decentralized framework. [\\[5\\]](#cite-id-awsvfCJOhoB5LWlX) [\\[3\\]](#cite-id-YrggkBGkgn3sY4WI)​\n\n## Team\n\nLium was founded by a developer known as Datura, who also goes by the aliases Pierre and Fish. Before founding Lium, he was a significant miner within the [Bittensor](https://iq.wiki/wiki/bittensor-tao) ecosystem, giving him deep experience with the network's mechanics and large-scale GPU operations. He is described as a respected figure in the community. The project is operated by the entity Datura AI Corp.
