NanoBlocks is an unofficial Python package built to ease the access to NANO cryptocurrency. It is intended to give an easy interface for programmers to play with the Nano Network, allowing most Nano common operations which includes creating new wallets and accounts, checking accounts information, making transactions and more.
An extensive documentation of the package can be found by reading the docs.
Installation
NanoBlocks can be installed through pip:
pip install nanoblocksGetting started
It is required to have a Nano node installed and configured in order to release all the functionalities that this package can give; even though it can still work offline for certain operations (like creating wallets, accounts, and building and signing blocks).
It is highly encouraged to get access to the node RPC and WebSocket servers. A guide for installation of the node can be found here. Furthermore, a nano-work-server access for work generation is also recommended to enable transactions.
Everything starts with the NanoNode and the NanoNetwork classes:
>>> from nanoblocks.node import NanoNode
>>> from nanoblocks.network import NanoNetwork
>> node = NanoNode("http://localhost:7076", "ws://localhost:7078")
>> node
[Node http://localhost:7076 (Nano V21.2)]
>> network = NanoNetwork(node)
>> network
[Node http://localhost:7076 (Nano V21.2)] (270 peers; 15362838 account)Having a NanoNetwork class instance, accounts in the network can be accessed as easy as follows:
>>> account = network.accounts["nano_39a73oy5ungrhxy5z5oao1xso4zo7dmgpjd4u74xcrx3r1w6rtazuouw6qfi"]
>>> account
nano_39a73oy5ungrhxy5z5oao1xso4zo7dmgpjd4u74xcrx3r1w6rtazuouw6qfi (

# To access an existing wallet by using the 64-Bytes seed:
>>> wallet = network.wallets["7F632A80ECCC54A058602CD64A81D23A6B4D7320562E4767C9EB0BBB1151CDF2"]
# Alternatively, it can be accessed with the BIP-39 24 words:
>>> wallet = network.wallets[['legal', 'bone', 'parent', 'sunset', 'shed', 'expand', 'ghost', 'airport', 'stone', 'favorite', 'innocent', 'inquiry', 'regular', 'ridge', 'life', 'shift', 'electric', 'dinner', 'kiss', 'blast', 'rain', 'pottery', 'daughter', 'execute']]
# Wallet information can be printed out
>>> print(wallet.seed)
7F632A80ECCC54A058602CD64A81D23A6B4D7320562E4767C9EB0BBB1151CDF2
>>> print(wallet.mnemonic)
['legal', 'bone', 'parent', 'sunset', 'shed', 'expand', 'ghost', 'airport', 'stone', 'favorite', 'innocent', 'inquiry', 'regular', 'ridge', 'life', 'shift', 'electric', 'dinner', 'kiss', 'blast', 'rain', 'pottery', 'daughter', 'execute']Which allows to access accounts as follows:
>>> account_0 = wallet.accounts[0]Easy, right? Check all what you can do by reading the docs!
