Summary

NFT operations are not possible in mainnet

Steps to reproduce

Attempt to register a protocol

Expected behavior

It should be possible to perform NFT framework operations in mainnet.

Problematic behavior

No operations are possible because it's not possible to register a protocol. Attempting to do so produces error: {"code":-26,"message":"64: version"}

Crown-core environment info

MX Linux 18.3

Crown-core application info

Crown version v0.14.0.0-Emerald (2020-03-09 07:53:34 +0000)

Relevant logs, dumps and/or screenshots

mark@x230:~/.crown$ crown-cli nftproto register marbles "Round Spherical Objects" CRWPsXLr4AUHK8RDvcGP6wFfndZc3P5hv4Sn 3
error: {"code":-26,"message":"64: version"}

The debug.log contains

ERROR: AcceptToMemoryPool : nonstandard transaction: version

which is due to chainparams.cpp:296

         fRequireStandard = true;

and main.cpp:1088

    // Rather not work on nonstandard transactions (unless -testnet/-regtest)
    string reason;
    if (Params().RequireStandard() && !IsStandardTx(tx, reason))
        return state.DoS(0,
                         error("AcceptToMemoryPool : nonstandard transaction: %s", reason),
                         REJECT_NONSTANDARD, reason);
