Lium Project Update

Get Caught Up

• Bittensor's first halving and the TaoFlow emission model. Bittensor executed its first halving on December 14, 2025, reducing daily TAO issuance from roughly 7,200 to 3,600 tokens 12. Alongside this, the transition to the TaoFlow (TFlow) emission model shifted subnet emission rewards to depend on an exponential moving average (EMA) of net staking flow rather than subnet token price, forcing subnets to compete for real capital inflows 2. This matters for compute subnets like Lium because it changes the economic incentives for attracting and retaining staked capital.
• Project Rubicon bridged Bittensor subnet tokens to broader Web3 markets. General TAO Ventures launched Project Rubicon, which uses Chainlink's Cross-Chain Interoperability Protocol (CCIP) to bridge Bittensor subnet tokens to the Base Layer 2 blockchain, enabling non-custodial liquid staking of subnet alpha tokens into tradable ERC-20 assets called xAlpha 4. It initially supports 17 Bittensor subnets with roughly $300,000 in liquidity each, which could unlock new liquidity and rewards for subnet owners 4.
• Growing institutional and infrastructure interest in Bittensor subnets. Institutional interest expanded with firms like Yuma Asset Management and Stillcore Capital launching funds targeting Bittensor subnets, and three public companies establishing TAO treasuries 1. A reimagined mobile wallet also launched to reduce onboarding friction, integrating Coinbase for direct fiat-to-TAO purchases and aggregating user holdings across TAO and subnet tokens .
