Ethereum Bech32 addresses starting with “bcrt…” in Regtest
In Ethereum, bech32 addresses are a standard format for storing transaction data. When generating these addresses with the getnewaddress command using Regtest, it is not uncommon to encounter addresses that start with “bcrt…”. This is likely due to a number of reasons, such as the way Bitcoin Core (BCC) handles address generation, or special settings used in Regtest.
What does “bcrt…” mean?
In bech32, the first three characters indicate the type of transaction data being stored. In this case, “bcrt” indicates that the address is a standard Bech32-encoded bitcoin basic transaction.
Why do we get addresses starting with “bcrt…”?
When Regtest generates these addresses using the getnewaddress command, it may not always follow the standard bech32 format or generate addresses that do not fit into this format. There are several reasons for this:
- Regtest settings: Regtest has different settings and options than Bitcoin Core. Some of these settings can lead to addresses being generated in a non-standard way.
- Transaction data
: Regtest may not always provide all the necessary information about the transaction data, resulting in incomplete or inconsistent addresses.
- Address generation algorithms: The
getnewaddresscommand uses different algorithms to generate Bech32 addresses, which can sometimes produce addresses that do not fit into the standard format.
Generating a Bech32 Address in Regtest
To generate a bech32 address using Regtest, use the following command:
regtest getnewaddress "bcrt"
This will output an address in the format “bcrt…” followed by your Bitcoin Core private key. Please note that this is just an example and may not work in all cases.
Sample Address
Here is a sample address generated using Regtest:
bcrt 1D0e8Ea6c5...C3...
Please note that the actual output may vary depending on your Regtest settings, Bitcoin Core version, and transaction data.
Conclusion
Generating bech32 addresses starting with “bcrt…” can occur for a variety of reasons related to Regtest and Bitcoin Core. Understanding these possible causes and knowing how to create a bech32 address on Regtest can help you troubleshoot issues or optimize your Ethereum development workflow.
