## About
lium (SN51) is the subnet token associated with Lium, a decentralized GPU rental marketplace operating as Bittensor Subnet 51. The project connects GPU providers, renters, miners, validators, and Bittensor subnet incentives around a marketplace for compute access. Available documentation describes Lium as a peer-to-peer compute platform where providers contribute machines, renters access GPU resources through the lium.io interface, and validators verify hardware specifications and performance before rewards are distributed through Bittensor subnet mechanics. The strongest validated launch reference is Bittensor.ai subnet data showing registration on July 26, 2025.

SN51 is not documented as an independent Layer-1 blockchain. It is best classified as a Bittensor subnet or subnet alpha token, with CoinGecko showing contract or netuid value 51 and tracking it in the Bittensor ecosystem. The technical architecture centers on decentralized compute rather than block production on a separate chain. Lium uses Bittensor subnet mechanics and Yuma Consensus context for emissions, while project-specific validators evaluate GPU miners through hardware and performance checks. The verified repository is Datura-ai/lium-io, listed with Python as the primary language and MIT licensing.

The project’s main use case is decentralized GPU rental for workloads such as machine learning, data analysis, and other compute-heavy applications. Providers can earn from both rental fees and Bittensor subnet emission, while renters gain access to GPU machines through the Lium platform. The ecosystem material references provider portal, SDK, CLI, pods, benchmark tooling, collateral, and confidential virtual machine documentation areas, indicating a practical product focus around operational compute supply and marketplace reliability rather than a general-purpose smart contract environment.

SN51 tokenomics are tied to the Bittensor subnet model. CoinGecko market data in the supplied summary reports a price of $14.78, market capitalization around $56.66 million, circulating and total supply of 3,834,730 SN51, and a maximum supply of 21,000,000 SN51. This implies about 18.26% of the maximum supply in circulation at the time captured. The provided source material does not include validated premine, PIP, ICO, venture funding, public-sale, or founder allocation data, so those values are not inferred.

Governance information remains limited. Lium operates inside the Bittensor subnet framework with owner, hotkey, validators, miners, and stakers, and Bittensor.ai reports an owner cut of 18.0%. However, the available data does not confirm a DAO, formal company, foundation, CEO, executive team, token voting mechanism, or community-governed treasury. Development activity appears active through the public GitHub repository and recent release names such as executor-v1.102, but a formal long-term roadmap was not available in the combined summary.
