nanopy's Issues

Problem installing nanopy on aarch64

It seems like both nanopy and nanolib can't be installed.

Machine: Raspberry PI4 + Ubuntu server 64bit

nanopy requires AMD64 with SSE2
nanolib seems having troubles with -mfpu=neon

Contact

Hello!

Couldn't find your contact info anywhere, so I'll just open an issue and ask my question. Hope that's alright.

I'm working on a REPL-type CLI light-wallet for Nano, also written in Python, that uses your PoW code.
Perhaps you'd be interested in working together?

/Robert

The only example in the community right now is nanollet. nanollet doesn't need a backend at all to access data from the network. It directly connects to the network as a peer, requests for the data it needs and publishes blocks that it wants to broadcast. All directly to the network.

I want to add a submodule in the library which provide functions with which users can add this capability to their tools.

Is the work difficulty up to date?

Probably I'm doing something dumb, but it looks like the default work_difficulty in nanopy (used by block_create) might need to be updated.

When I try to do a send, the RPC response consistently includes "error": "Block work is less than threshold"

def main():
    connection = nanopy.rpc.RPC(url="https://proxy.powernode.cc/proxy")
    info = connection.account_info(ACCOUNT, representative=True)
    balance = int(info["balance"]) - int(nanopy.nano_to_raw("5"))

    if balance < 0:
        raise ValueError("You're out of nano.")

    balance = str(balance)

    nb = nanopy.block_create(PRIVATE, info["frontier"], info["representative"], balance, nanopy.account_key(PRIMARY))

    result = connection.process(nb)
    print(json.dumps(result, sort_keys=True, indent=4))

Issue installing library

Hello, I've been trying to install the library and got this error, any ideas on what it could be?

Thanks in advance :)

Installing without blake2b

This would allow using the library in non-SSE2-enabled devices like a raspberry pi.
