Cross-Chain Mining
Cross-chain mining expands the potential of Mineable UTXOs by enabling cryptographic collision challenges across multiple blockchains. This concept not only increases security but also creates opportunities for miners to claim rewards from several chains simultaneously.
- Unified Incentives: Align miner rewards and participation across different networks.
- Increased Mining Rewards: Maximize profits by solving challenges on multiple chains.
- Enhanced Security: Each solved challenge acts as a checkpoint, reinforcing the network's robustness.
Overview
Cross-chain mining involves setting up identical SHA-1 collision challenges on different blockchains. Miners or users who solve the collision on one chain can often use the same preimages to claim rewards on other chains, provided the challenge scripts and reward structures align.
- Unifying miner incentives across chains.
- Efficiently utilizing mining resources.
- Building an interconnected blockchain ecosystem where rewards span multiple networks.
Example Workflow
-
Setup: Deploy a SHA-1 collision challenge on Bitcoin, Litecoin, and Dogecoin networks.
-
Mining: Miners solve the challenge by finding a solution that collides with preimage1 to produce the same SHA-1 hash.
-
Reward Claim: The miner submits the preimages to each chain, claiming rewards from all.
-
Propagation: The solution can be verified across chains, ensuring no double-spending or inconsistencies.
- Standardized Challenge Scripts: Ensure the locking and unlocking scripts are identical across chains to avoid compatibility issues.
- Cross-Chain Aggregators: Use aggregators to monitor challenges and solutions across chains, simplifying miner participation.
- Fee Structures: Adjust fee distributions to incentivize cross-chain miners while maintaining fairness.
