- Assignment
- A server-authorized unit of work linking one range to an anonymous client UUID for a limited lease period.
- Backend
- The execution family used for a search: CUDA, OpenCL or CPU.
- Bitcoin Puzzle
- A public challenge funded through Bitcoin addresses whose private keys were intentionally selected from constrained numeric intervals.
- Checkpoint
- The most recent key position supported by a progress report. It helps recovery and completion validation.
- Client UUID
- A random identifier generated locally for one OpenPuzzle installation. It is not a user account.
- Completed range
- An interval whose engine execution and final checkpoint passed the server's full-range validation.
- CUDA
- NVIDIA's GPU computing platform, used by the bundled CUDA BitCrack engine.
- Engine
- The local executable that performs elliptic-curve key testing. OpenPuzzle coordinates and monitors it.
- Keyspace
- The complete numeric interval containing every private-key candidate allowed by a particular puzzle.
- Lease
- The period during which an assignment remains valid. Successful progress heartbeats renew it.
- MKey/s
- Millions of candidate keys tested per second. It is a throughput measurement, not a success probability.
- OpenCL
- A portable compute API used by the bundled OpenCL BitCrack engine on compatible devices.
- Range
- A contiguous hexadecimal interval inside a puzzle keyspace.
- Safe stop
- A request that lets active work finish, prevents a new assignment and exits the runtime automatically.
- WIF
- Wallet Import Format, a human-readable encoding of a Bitcoin private key. OpenPuzzle never uploads it.
