Module cfxcore::pow

Structs

• CacheBuilder
• PowComputer
• ProofOfWorkConfig
• ProofOfWorkProblem
• ProofOfWorkSolution
• TargetDifficultyManager
  This is a data structure to cache the computed target difficulty of a adjustment period. Each element is indexed by the hash of the upper boundary block of the period.

Enums

• MiningType

Constants

• POW_STAGE_LENGTH

Functions

• boundary_to_difficulty
  Convert boundary to its original difficulty. Basically just f(x) = 2^256 / x.
• compute_inv_x_times_2_pow_256_floor
  Compute [2^256 / x], where x >= 2 and x < 2^256.
• difficulty_to_boundary
  Convert difficulty to the target boundary. Basically just f(x) = 2^256 / x.
• nonce_to_lower_bound
• pow_hash_to_quality
• pow_quality_to_hash
  This should only be used in tests.
• target_difficulty
  This function computes the target difficulty of the next period based on the current period. cur_hash should be the hash of the block at the current period upper boundary and it must have been inserted to BlockDataManager, otherwise the function will panic. num_blocks_in_epoch is a function that returns the epoch size under the epoch view of a given block.
