| The addr (IP address) message relays connection information for peers on the network. More... | |
| constexpr 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... | |

| The getheaders message requests a headers message that provides block headers starting from a particular point in the block chain. More... | |
| constexpr const char * | NetMsgType::TX {"tx"} |
| The tx message transmits a single transaction. More... | |
| constexpr 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... | |
| constexpr const char * | NetMsgType::BLOCK {"block"} |
| The block message transmits a single serialized block. More... | |
| constexpr 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... | |
| constexpr 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... | |
| constexpr const char * | NetMsgType::PING {"ping"} |
| The ping message is sent periodically to help confirm that the receiving peer is still connected. More... | |
| constexpr 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... | |
| constexpr 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... | |
| constexpr 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... | |
| constexpr 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... | |
| constexpr const char * | NetMsgType::FILTERCLEAR {"filterclear"} |
| The filterclear message tells the receiving peer to remove a previously-set bloom filter. More... | |
| constexpr const char * | NetMsgType::SENDHEADERS {"sendheaders"} |
| Indicates that a node prefers to receive new block announcements via a "headers" message rather than an "inv". More... | |
| constexpr 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... | |
| constexpr const char * | NetMsgType::SENDCMPCT {"sendcmpct"} |
| Contains a 1-byte bool and 8-byte LE version number. More... | |
| constexpr const char * | NetMsgType::CMPCTBLOCK {"cmpctblock"} |
| Contains a CBlockHeaderAndShortTxIDs object - providing a header and list of "short txids". More... | |
| constexpr const char * | NetMsgType::GETBLOCKTXN {"getblocktxn"} |
| Contains a BlockTransactionsRequest Peer should respond with "blocktxn" message. More... | |
| constexpr const char * | NetMsgType::BLOCKTXN {"blocktxn"} |
| Contains a BlockTransactions. More... | |
| constexpr const char * | NetMsgType::GETCFILTERS {"getcfilters"} |
| getcfilters requests compact filters for a range of blocks. More... | |

| cfilter is a response to a getcfilters request containing a single compact filter. More... | |
| constexpr 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... | |
| constexpr 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... | |
| constexpr const char * | NetMsgType::GETCFCHECKPT {"getcfcheckpt"} |
| getcfcheckpt requests evenly spaced compact filter headers, enabling parallelized download and validation of the headers between them. More... | |
| constexpr 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... | |
| constexpr const char * | NetMsgType::WTXIDRELAY {"wtxidrelay"} |
| Indicates that a node prefers to relay transactions via wtxid, rather than txid. More... | |
