# Send Transaction
|
||
|
|
|
||
|
|
The purpose of this exercise is to create a simple Bitcoin transaction locally using the command line. As we use new tools this exercise is guided.
|
||
|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
- Install a Bitcoin node. There are two solutions :
|
||
|
|
- Use a preconfigured image for a virtual machine such as [cryptotux](https://cryptotux.org/)
|
||
|
|
- Install manually by downloading and installing the Bitcoin Core software from [github](https://github.com/bitcoin/bitcoin/releases).
|
||
|
|
- Launch Bitcoin core daemon on _regtest_ network. You can do so with `bitcoind -regtest -fallbackfee=0.00000003` assuming the executable is in your shell's path.
|
||
|
|
- Create manually a wallet and two addresses on _Bitcoin regtest_. You may do this by running the following commands
|
||
|
|
```bash
|
||
|
|
bitcoin-cli createwallet "testwallet"
|
||
|
|
bitcoin-cli getnewaddress
|
||
|
|
bitcoin-cli getnewaddress
|
||
|
|
```
|
||
|
|
- Generate 101 blocks to get fresh bitcoins. You need 101 blocks as the Bitcoin you receive from mining are locked for 100 blocks.
|
||
|
|
You may use the following command `bitcoin-cli -regtest generatetoaddress 101 <your address>`
|
||
|
|
|
||
|
|
- Send a transaction of 2 bitcoins to the second address.
|
||
|
|
|
||
|
|
- List the last transactions `bitcoin-cli listtransactions`
|
||
|
|
- Create a js file and exports the hash of your transaction in a variable `txid`.
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
```js
|
||
|
|
exports.txid =
|
||
|
|
"be3d0d245e7dce50964ac9157aee7e18a3828e11d89f72ee0bc3f76b526e5bb";
|
||
|
