Variables | |
const char * | NetMsgType::VERSION = "version" |
The version message provides information about the transmitting node to the receiving node at the beginning of a connection. More... | |
const char * | NetMsgType::VERACK = "verack" |
The verack message acknowledges a previously-received version message, informing the connecting node that it can begin to send other messages. More... | |
const char * | NetMsgType::ADDR = "addr" |
The addr (IP address) message relays connection information for peers on the network. More... | |
const char * | NetMsgType::ADDRV2 = "addrv2" |
The addrv2 message relays connection information for peers on the network just like the addr message, but is extended to allow gossiping of longer node addresses (see BIP155). More... | |
const char * | NetMsgType::SENDADDRV2 = "sendaddrv2" |
The sendaddrv2 message signals support for receiving ADDRV2 messages (BIP155). More... | |
const char * | NetMsgType::INV = "inv" |
The inv message (inventory message) transmits one or more inventories of objects known to the transmitting peer. More... | |
const char * | NetMsgType::GETDATA = "getdata" |
The getdata message requests one or more data objects from another node. More... | |
const char * | NetMsgType::MERKLEBLOCK = "merkleblock" |
The merkleblock message is a reply to a getdata message which requested a block using the inventory type MSG_MERKLEBLOCK. More... | |
const char * | NetMsgType::GETBLOCKS = "getblocks" |
The getblocks message requests an inv message that provides block header hashes starting from a particular point in the block chain. More... | |
const char * | NetMsgType::GETHEADERS = "getheaders" |
The getheaders message requests a headers message that provides block headers starting from a particular point in the block chain. More... | |
const char * | NetMsgType::TX = "tx" |
The tx message transmits a single transaction. More... | |
const char * | NetMsgType::HEADERS = "headers" |
The headers message sends one or more block headers to a node which previously requested certain headers with a getheaders message. More... | |
const char * | NetMsgType::BLOCK = "block" |
The block message transmits a single serialized block. More... | |
const char * | NetMsgType::GETADDR = "getaddr" |
The getaddr message requests an addr message from the receiving node, preferably one with lots of IP addresses of other receiving nodes. More... | |
const char * | NetMsgType::MEMPOOL = "mempool" |
The mempool message requests the TXIDs of transactions that the receiving node has verified as valid but which have not yet appeared in a block. More... | |
const char * | NetMsgType::PING = "ping" |
The ping message is sent periodically to help confirm that the receiving peer is still connected. More... | |
const char * | NetMsgType::PONG = "pong" |
The pong message replies to a ping message, proving to the pinging node that the ponging node is still alive. More... | |
const char * | NetMsgType::NOTFOUND = "notfound" |
The notfound message is a reply to a getdata message which requested an object the receiving node does not have available for relay. More... | |
const char * | NetMsgType::FILTERLOAD = "filterload" |
The filterload message tells the receiving peer to filter all relayed transactions and requested merkle blocks through the provided filter. More... | |
const char * | NetMsgType::FILTERADD = "filteradd" |
The filteradd message tells the receiving peer to add a single element to a previously-set bloom filter, such as a new public key. More... | |
const char * | NetMsgType::FILTERCLEAR = "filterclear" |
The filterclear message tells the receiving peer to remove a previously-set bloom filter. More... | |
const char * | NetMsgType::SENDHEADERS = "sendheaders" |
Indicates that a node prefers to receive new block announcements via a "headers" message rather than an "inv". More... | |
const char * | NetMsgType::FEEFILTER = "feefilter" |
The feefilter message tells the receiving peer not to inv us any txs which do not meet the specified min fee rate. More... | |
const char * | NetMsgType::SENDCMPCT = "sendcmpct" |
Contains a 1-byte bool and 8-byte LE version number. More... | |
const char * | NetMsgType::CMPCTBLOCK = "cmpctblock" |
Contains a CBlockHeaderAndShortTxIDs object - providing a header and list of "short txids". More... | |
const char * | NetMsgType::GETBLOCKTXN = "getblocktxn" |
Contains a BlockTransactionsRequest Peer should respond with "blocktxn" message. More... | |
const char * | NetMsgType::BLOCKTXN = "blocktxn" |
Contains a BlockTransactions. More... | |
const char * | NetMsgType::GETCFILTERS = "getcfilters" |
getcfilters requests compact filters for a range of blocks. More... | |
const char * | NetMsgType::CFILTER = "cfilter" |
cfilter is a response to a getcfilters request containing a single compact filter. More... | |
const char * | NetMsgType::GETCFHEADERS = "getcfheaders" |
getcfheaders requests a compact filter header and the filter hashes for a range of blocks, which can then be used to reconstruct the filter headers for those blocks. More... | |
const char * | NetMsgType::CFHEADERS = "cfheaders" |
cfheaders is a response to a getcfheaders request containing a filter header and a vector of filter hashes for each subsequent block in the requested range. More... | |
const char * | NetMsgType::GETCFCHECKPT = "getcfcheckpt" |
getcfcheckpt requests evenly spaced compact filter headers, enabling parallelized download and validation of the headers between them. More... | |
const char * | NetMsgType::CFCHECKPT = "cfcheckpt" |
cfcheckpt is a response to a getcfcheckpt request containing a vector of evenly spaced filter headers for blocks on the requested chain. More... | |
const char * | NetMsgType::WTXIDRELAY = "wtxidrelay" |
Indicates that a node prefers to relay transactions via wtxid, rather than txid. More... | |
const char * | NetMsgType::SENDTXRCNCL = "sendtxrcncl" |
Contains a 4-byte version number and an 8-byte salt. More... | |
