How It Works

Real cryptographic computation, right in your browser

1
Pollard Kangaroo Algorithm -- Your browser runs the Pollard Kangaroo algorithm on the secp256k1 elliptic curve. This is the same curve Bitcoin uses for its public key cryptography.
2
Random Walks -- Each operation performs a pseudo-random walk on the curve, searching for Distinguished Points (DPs). A DP is a point whose hash meets a specific threshold condition.
3
Collision Detection -- DPs are sent to our central server which stores them and checks for collisions. When a tame kangaroo and a wild kangaroo land on the same DP, the private key can be derived.
4
Distributed Power -- The more people mining, the faster we find the key. Each participant independently explores a portion of the search space, and the server correlates all results.
5
Real Computation -- Your browser does real cryptographic computation -- no fake mining. Every operation is a genuine elliptic curve point addition contributing to solving Bitcoin Puzzle #135.
6
Two Ways to Mine -- Browser mining works everywhere with zero setup and moderate speed (~5,000 ops/sec). CLI mining requires an NVIDIA GPU but delivers maximum performance (~400M ops/sec on an RTX 3060) with a single-command install. Both methods contribute to the same distributed search and your results are tracked under one account.
