#Picocoin

Tiny bitcoin library, with lightweight client and utils

libccoin library dependencies: OpenSSL

picocoin client dependencies: OpenSSL libevent 2.x jansson 2.x (2.1 used for development)

block relay daemon (brd) dependencies: OpenSSL libevent 2.x

In general, the program stores settings in a key/value map. These key=value parameters may be specified on the command line, or in a configuration file.

The command line is processed in-order. For example

$ ./picocoin value=1 list-settings value=2 list-settings

will execute the "list-settings" command twice, each with "value" setting initialized to a different parameter.

Similarly, you may read multiple configuration files into the settings map:

$ ./picocoin config=file1 config=file2 config=file3

Format: address SPACE port

Manually add P2P node to peer manager.

Specify a pathname to the configuration file.

Specify a pathname to the wallet data file. Default "picocoin.wallet"

AES encryption is applied to the wallet. Passphrase is specified via environment variable PICOCOIN_PASSPHRASE.

Enable additional debug output.

TCP connect(2) timeout.

Select blockchain and network. Reads the "chain" settings variable. Acceptable values are "chain=bitcoin" and "chain=testnet3". Updates internal parameters (pchMessageStart / network magic, genesis block, ...)

Query and display bitcoin DNS seeds, for P2P node addresses.

Output these commands and recognized settings.

Display settings map.

Generate a new bitcoin address (ECDSA keypair). Store it in the current wallet,

Initialize a new wallet. Refuses to initialize, if the filename already exists.

Synchronize with network: send any pending payments, and check for new incoming payments.

List all bitcoin addresses in wallet.

Dump entire wallet contents, including all private keys.

Informational summary of wallet data.
