# MineBridge Core Expansion

From the outset we have taken a product-led marketing approach and will continue to lead with product. To that end, we’re sharing here the primary product roadmap for RuneMine by MineLabs, split into three distinct phases.

[Phase 1: Evolution ](#phase-1-evolution)

[Phase 2: Odyssey](#phase-2-odyssey) 

[Phase 3: Ascension](#phase-3-ascension)

Timeline is estimated and lays out the general vision for the MineLabs roadmap and may be subject to change.

### Phase 1: Evolution

Focuses on initiating the decentralization of the MineBridge with Multi-Party Computation (MPC)/Threshold Signature Scheme (TSS) and increasing the number of trusted validators. 

Evolution emphasizes growth and security, beginning with a careful selection of validators based on their reputation and monetary stake, similar to Chainlink’s model. 

The process involves validators independently verifying and signing off on transactions before a majority consensus approves bridge transfers.<br>

### Phase 2: Odyssey

Broaden the validator network and enhance connectivity between Solana, Bitcoin, and additional ecosystems, lay the groundwork for BitVM2 implementation.&#x20;

Research and development focus on signature sharing solutions and integrating more complex blockchain environments, including direct developments on Bitcoin’s integration challenges through multisig and TSS solutions.

### Phase 3: Ascension

Full transition to BitVM2-based bridging solution.&#x20;

Marks the transition to a fully decentralized bridging solution using BitVM2. Ascension involves deploying a bridge based on the BitVM2 design, enabling us to reduce the amount of trust imparted on bridge operators, and optimizing the system to handle cross-chain transactions more efficiently.&#x20;

The goal is to establish a permissionless and trustless framework for asset transfers, positioning Solana as a leading Layer 2 solution for Bitcoin-related transactions.
