RPC. Checksum: SHA256(SHA256( empty ) Data Messages Edit History Report Issue Discuss The following network messages all request or provide data related to transactions and blocks. This allows future versions to send duplicate sendcmpct messages with different versions as a part of a version handshake for future versions. Bytes Name Data Type Description 8 feerate uint64_t The fee rate (in satoshis per kilobyte) below which transactions should not be relayed to this peer. MurmurHash3(nHashNum * 0xFBA4C795 nTweak, vDataToHash) (ze * 8) Each data element to be added to the filter is hashed by nHashFuncs number of hash functions. 31402 Bitcoin Core.3.15 (Oct 2010) Added time field to addr message.
Block version: 1 7469f8efb7421dc. Bitcoin Core code and this document refers to these variable length integers as compactSize. The seed is the first parameter; the data to be hashed is the second parameter. It has been proposed in Bitcoin Core issue #2381 that the transactions should be sorted before being processed by the filter.
More generally still, in the analysis of this section I have implicitly assumed a kind of symmetry between different miners. But when Bob and Charlie ask the network to validate their respective transactions, Alices sock puppet identities swamp the network, announcing to Bob that theyve validated his transaction, and to Charlie that theyve validated his transaction, possibly fooling one or both into accepting the transaction. Second, by operating in this way we remove the need for any central authority issuing serial numbers. Proof-of-work Suppose Alice wants to double spend in the network-based protocol I just described. Create a complete merkle tree with txids on the bottom row and all the other hashes calculated up to the merkle root on the top row. Other participants in the Infocoin network can verify that is a valid solution to the proof-of-work puzzle. 2 addr_trans port uint16_t Required Added in protocol version 106. Although Bitcoin addresses arent immediately associated to real-world identities, computer scientists have done a great deal of work figuring out how to de-anonymize anonymous social networks.
