Ethereum: Bitcoin Core Connection Edition
As an ethereum blockchain developer or user, it is important to ensure that the network connections are safe. In this article, we will solve the problem that can occur using Bitcoin Core (BTC-C) to connect to the Ethereum network Linux.
Problem: Incorrect RPC user/password
The error message received indicates that there is an authorization error due to the wrong “RPCUSER” or “RPCPASSword”. This can happen if your username and password do not match BTC-C use. Ask this question step by step:
Step 1: Review the installation
Before continuing, check that BTC-C installed this command correctly:
`Bash
SUDO APT-GET Update && Sudo APT-GET Install Bitcoin-Core
`
If you did not use “apt -get” or if the installation was unsuccessful, try again.
2. Step: Check your username and password
You mentioned you that the host system is Linux Debian Stretch (9/X test). Make sure you create a file with your username with appropriate permits. Create a new file /Home/myusername/.Bitcoinrc" or attach an existing file ~/.Bitcoin.conf end:
Bash
Sudo Nano ~/. Bitcoinrc
`
Add the following rows by replacing your actual username and password:
`Makefile
rpcuser = myusername
rpcpassword = mypassword
`
Replace MyUSername and MyPassword with the desired authentication data.
Step 3: Check your configuration
Restart BTC-C after the configuration file update:
`Bash
SUDO SYSTEMCTL Restarts Bitcoin MAG
`
Now try connecting to the Ethereum network with BTC-C. Open the terminal, find the directory /home/myusername/downloads (replace" ~with the actual username):
`Bash
CD/HOME/myusername/downloads
`
Run this team:
`Bash
Bitcoin-Cli getminginfo-ersion
`
This must show the BTC-C version installed in the system. If you continue to experience problems, try to restore the configuration file or update the BTC-C latest version.
Example Cases:
- Create a new wallet by launching
Sudo Bitcoin-Qt-Fret-Directory =/Home/Myusername/.Bitcoin-Wallet".
- Check the connection using "Bitcoin-Cli GetBalance"
- Try connecting to the Ethereum network usinghttps: // mainnet.infura.io/v3/thood-id”.
