Bitcoin Core RPC teams: Block Creating with Coinbase Address
The Bitcoin Core (BTC) node provides peaceful API interaction with blockchain. One useful feature is the ability to generate a block using the input address and other parameters. In this article, we will study two separate teams that can help create a block body and its Merkle root based on the address you specify.
Team 1: Generate block body
Team line tool “Bitcoin-Cli”, which is used by Bitcoin cores, allows you to generate a new block using the subcutaneous Generateblock subcutaneous. Specifying the input address requires a flag “-intut. Here's how you can use this command:
bash
Bitcoin -Cli GAREBLOCK -inut 1M9Btevzkv6W9QF5F5F3PN7Y8J9ZDJC1TF -M 2
`
It will generate a new block with the input address 1M9Bteevzkv6W9QF5F3PN7Y8J9ZDJC1TF and Merkle root, which can be tested using other commands.
Team 2: Generate Merkle root
The Bitcoin-Cli tool also provides the GetblockTemplate subcommitty, which allows you to generate a block template with a specific input address. Specifying the output format (in this case, Merkle root) requires a flag -m. Here’s how you can use this command:
`bash
Bitcoin -Cli GetblockTemplate -M 2 -Itut 1M9Btevzkv6W9QF5F5F3PN7Y8J9ZDJC1TF
`
This will generate a block template with the specified input address, and then you can use other commands to create the actual block.
COINBASE address check in a new block
To check if the Bitcoin-Cli tool generates a block, including your input address, you can use the following command:
`bash
Bitcoin -Cli Gettransaction -ID 1234567890 -Sadress 1M9Btevzkv6W9QF5F5F3PN7Y8J9ZDJC1TF
`
It asks the transaction blockchain with the specified input address. The Bitcoin-Cli tool should draw the transaction information, including the root of Merkle.
Example of use of use
Let’s say you want to create a new block that includes your input address 1M9BtevzkV6W9QF5F3PN7Y8J9ZDJC1TF and its Merkle root. You can use the following commands:
`bash
Generate blocks of blocks
Bitcoin -Cli GAREBLOCK -inut 1M9Btevzkv6W9QF5F5F3PN7Y8J9ZDJC1TF -M 2
Get block template with Merkle root
Bitcoin -Cli GetblockTemplate -M 2 -Itut 1M9Btevzkv6W9QF5F5F3PN7Y8J9ZDJC1TF> Block_template.JSON
Generate a transaction for the new block
Bitcoin -Cli Sendrawtransaction -TXN -Address 1M9Bteevzkv6W9QF5F3PN7Y8J9ZDJC1TF -OutPutchain
`
This will create a new transaction that includes the input address and its Merkle root, which can then be used to create a new block.
