NetworkRequest provides the inbound interface to the high level 'the rest of the network' abstraction.

Variants

Peers

Requests peer information

BlocksByHash(HashSet<u256>)

Requests all blocks with provided hashes

TransactionsByHash(HashSet<u256>)

Requests all transactions with provided hashes

Headers

Requests headers starting with the first header in the vec. If max_responses is not provided, the Service will attempt to return every header up to the current tip.

last_known_headers should be ordered from newest to oldest (i.e. from now toward Genesis block) if it contains more than one item

Fields of Headers

last_known_headers: Vec<u256>max_responses: Option<usize>

PushTransaction(Transaction)

Pushes a transaction to the network using unsolicited Tx Message

AdvertiseTransactions(HashSet<u256>)

Advertises to peers that each transaction is available using an inv message containing the Tx Hash.

AdvertiseBlock(HashSet<u256>)

Advertises to peers that a block is available using an inv message containing its hash

Mempool

Request a peer's view of the mempool. By default, the Service should aggregate responses from a small subset of peers.
