(this is known as "pool difficulty" or "pdiff. How soon might I expect to generate a block? There are no guarantees you will win every N days. What network hash rate results in a given difficulty? That means the hash rate of the network was D * 2*48 / 0xffff / 600 over the previous 2016 blocks. Write rNonce:, hash: ".format(nonce, hash:-1.encode hex dout. The bitcoin bits means the 'target' hash value, the new generated block must meet a condition: block header's double SHA-256 hash value must less than this 'target' value.
By the way, the nNonce is one of the fields in block header structure: struct header_structure / bytes name uint32_t nVersion; / 4 version uint8_t hashPrevBlock32; / 32 previous block header hash uint8_t hashMerkleRoot32; / 32 merkle root hash uint32_t nTime; / 4 time uint32_t. The minimum difficulty, when the target is at the maximum allowed value,. At the desired rate of one block each 10 minutes, 2016 blocks would take exactly two weeks to find. Also 0x008000 is the smallest positive valid value. Book, table of content, explain me like I'm five, sky is the limit? How is difficulty stored in blocks?
