- A hash160 collision refers to finding different private keys that generate the same Bitcoin address.
- The LBC pool is designed to find hash160 collisions by searching through a partitioned 160-bit space.
- RIPEMD160 is not injective, meaning multiple private keys can produce the same Bitcoin address.
- The pool uses a Bloom filter to check generated hash160 values against existing funded addresses.
- The search focuses on addresses with funds to incentivize rightful owners to reclaim them if a collision is found.
- The pool avoids redundant work by assigning unique intervals to clients and tracking progress.
- Finding a collision in unfunded addresses is less impactful as owners may not notice or care.
- The effective search space for collisions is reduced to ~136.17 bits due to the uniform distribution of private keys.
