Bitcoin.Core.RPC

Description

We provide limited access to the bitcoin-core daemon RPC interface. RPC method descriptions come from the bitcoind RPC help pages.

Synopsis

Interacting with bitcoind

runBitcoind Source #

Arguments

:: Manager 
-> String

host

-> Int

port

-> BasicAuthData 
-> BitcoindClient a 
-> IO (Either BitcoindException a) 

Convenience function for sending a RPC call to bitcoind

cookieClient Source #

Arguments

:: Manager 
-> FilePath

path to the cookie file

-> String

host

-> Int

port

-> BitcoindClient r 
-> IO (Either BitcoindException r) 

Send a RPC call to bitcoind using credentials from a cookie file

basicAuthFromCookie Source #

Arguments

:: FilePath

path to the cookie file

-> IO BasicAuthData 

Parse a username and password from a file. The contents of the file should be exactly "username:password" (not base64 encoded).

mkBitcoindEnv Source #

Arguments

:: Manager 
-> String

bitcoind host

-> Int

bitcoind RPC port

-> ClientEnv 

Convenience function for connecting to bitcoind

data BitcoindException Source #

Exceptions resulting from interacting with bitcoind

Constructors

RpcException String

The error message returned by bitcoind on failure

ClientException ClientError 
DecodingError String 

Transactions

getTransaction :: TxHash -> Maybe BlockHash -> BitcoindClient Tx Source #

By default this function only works for mempool transactions. When called with a blockhash argument, getrawtransaction will return the transaction if the specified block is available and the transaction is found in that block. When called without a blockhash argument, getrawtransaction will return the transaction if it is in the mempool, or if -txindex is enabled and the transaction is in a block in the blockchain.

sendRawTransaction :: Text -> Maybe Double -> BitcoindClient TxHash Source #

Submit a raw transaction (serialized, hex-encoded) to local node and network.

sendTransaction :: Tx -> Maybe Double -> BitcoindClient TxHash Source #

A version of sendRawTransaction that handles serialization

testMempoolAccept :: [Tx] -> Maybe Double -> BitcoindClient [MempoolTestResult] Source #

Returns result of mempool acceptance tests indicating if the transactions would be accepted by mempool. This checks if the transaction violates the consensus or policy rules.

Blocks

getBlock :: BlockHash -> BitcoindClient Block Source #

Produce the block corresponding to the given BlockHash if it exists.

getBlockFilter :: BlockHash -> BitcoindClient CompactFilter Source #

Retrieve a BIP 157 content filter for a particular block.

getBlockHeader :: BlockHash -> BitcoindClient BlockHeader Source #

Returns the header of the block corresponding to the given BlockHash

getBlockHash :: BlockHeight -> BitcoindClient BlockHash Source #

Returns hash of block in best-block-chain at height provided.

getBlockCount :: BitcoindClient Word32 Source #

Returns the height of the most-work fully-validated chain. The genesis block has height 0.

getDifficulty :: BitcoindClient Scientific Source #

Returns the proof-of-work difficulty as a multiple of the minimum difficulty.

getBestBlockHash :: BitcoindClient BlockHash Source #

Returns the hash of the best (tip) block in the most-work fully-validated chain.

getBlockStats :: BlockHash -> BitcoindClient BlockStats Source #

Compute per block statistics for a given window. All amounts are in satoshis. It won't work for some heights with pruning.

getChainTips :: BitcoindClient [ChainTip] Source #

Return information about all known tips in the block tree, including the main chain as well as orphaned branches.

getChainTxStats :: Maybe Word32 -> Maybe BlockHash -> BitcoindClient ChainTxStats Source #

Compute statistics about the total number and rate of transactions in the chain.

Mempool

getMempoolInfo :: BitcoindClient MempoolInfo Source #

Returns details on the active state of the TX memory pool.

getMempoolAncestors :: TxHash -> BitcoindClient [TxHash] Source #

If txid is in the mempool, returns all in-mempool ancestors.

getMempoolDescendants :: TxHash -> BitcoindClient [TxHash] Source #

If txid is in the mempool, returns all in-mempool descendants.

getRawMempool :: BitcoindClient [TxHash] Source #

Returns all transaction ids in memory pool.

Network

getPeerInfo :: BitcoindClient [PeerInfo] Source #

Returns data about each connected network node.

getConnectionCount :: BitcoindClient Word16 Source #

Returns the number of connections to other nodes.

getNodeAddresses :: Maybe Word32 -> BitcoindClient [NodeAddress] Source #

Return known addresses which can potentially be used to find new nodes in the network

getAddedNodeInfo Source #

Arguments

:: Maybe Text

optionally specify a node by address

-> BitcoindClient [NodeInfo] 

Returns information about the given added node, or all added nodes (note that onetry addnodes are not listed here)

listBanned :: BitcoindClient [Text] Source #

List all banned IPs/Subnets.

getNetTotals :: BitcoindClient NetTotals Source #

Returns information about network traffic, including bytes in, bytes out, and current time.

Control

stop :: BitcoindClient () Source #

Request a graceful shutdown of Bitcoin Core.

uptime :: BitcoindClient Word32 Source #

Returns the total uptime of the server (in seconds)

data Command Source #

Commands as understood by addNode

Constructors

Add 
Remove 
OneTry 

addNode Source #

Arguments

:: Text

node address host:port

-> Command 
-> BitcoindClient () 

Attempts to add or remove a node from the addnode list; or try a connection to a node once. Nodes added using addnode are protected from DoS disconnection and are not required to be full nodes/support SegWit as other outbound peers are (though such peers will not be synced from).

disconnectNode Source #

Arguments

:: Text

node address host:port

-> BitcoindClient () 

Immediately disconnects from the specified peer node.

clearBanned :: BitcoindClient () Source #

Clear all banned IPs.

generateToAddress Source #

Arguments

:: Word32

number of blocks to generate

-> Text

address for the coinbase reward

-> Maybe Word32

how many iterations to try

-> BitcoindClient [BlockHash] 

Generate blocks in regtest mode
