Dogecoin

To work with Dogecoin, utilize the official command-line tool: DogecoinCore.

Dogecoin shares many similarities with Bitcoin, including its signature algorithm and command-line tools. Here, we will focus on the distinctive aspects that set Dogecoin apart.

Installation and Configuration

Download

  • It's essential to note that, much like BitcoinCore on Mac, Dogecoin provides GUI tools exclusively.
  • For configuration, you can use the official default settings. If you prefer not to synchronize with online nodes, you can add proxy=127.0.0.1:12345 to the configuration, using a non-existent proxy.

Start Dogecoin with the following command:

./dogecoind -daemonwait

Generate a Key

When using dogecoin-cli for the first time, the getaddressesbyaccount command will automatically generate a new key group. Account information is stored in wallet.dat.

./dogecoin-cli getaddressesbyaccount ""
[
  "DNF59P3dX2S2i188aPfBfL4aecs9gWtBt8"
]

A Dogecoin address always begins with the letter D, followed by content encoded in Base58, which includes the public key hash and a checksum. You can find the code to parse and check addresses here.

Sign

Dogecoin Core supports signing and verifying messages.

./dogecoin-cli signmessage DNF59P3dX2S2i188aPfBfL4aecs9gWtBt8 00112233445566778899aabbccddeeff00112233445566778899aabbccddeeff

Output:

IIu/kxASl/W/5o3bjTD4KKBCQKcsDPUdp0+1Xu4vy0FhcpSfsIPu5Mi90VV0FGsN2gdlUvQFswTI886CeKNp7So=

The output signature data is Base58 encoded and can be used directly in ckb-auth.

To verify with Dogecoin Core:

./dogecoin-cli verifymessage DNF59P3dX2S2i188aPfBfL4aecs9gWtBt8 IIu/kxASl/W/5o3bjTD4KKBCQKcsDPUdp0+1Xu4vy0FhcpSfsIPu5Mi90VV0FGsN2gdlUvQFswTI886CeKNp7So= 00112233445566778899aabbccddeeff00112233445566778899aabbccddeeff

Output:

true

Verify

To verify in ckb-auth-cli:

ckb-auth-cli dogecoin verify -a DNF59P3dX2S2i188aPfBfL4aecs9gWtBt8 -s IIu/kxASl/W/5o3bjTD4KKBCQKcsDPUdp0+1Xu4vy0FhcpSfsIPu5Mi90VV0FGsN2gdlUvQFswTI886CeKNp7So= -m 00112233445566778899aabbccddeeff00112233445566778899aabbccddeeff

Verification in Dogecoin is quite similar to Bitcoin, with the exception of address handling. For the most part, Bitcoin code can be used.
