Sending Bitcoins Using Just A Public and Private Key
When using the Bitcoin command line client (BCC) on Linux, you can use only a public key and private key to send coins from an address. This requires some basic understanding of Bitcoin’s Blockchain Structure and Cryptography.
What is a public and private key?
In Bitcoin, each user has a unique pair of keys:
- Public Key : A 65-Character String used for transactions (e.g.,
M/0/C/X/P/0/Y/0/R/0/B/0/W/0/M /0/C/0/U/0/L/0/J/0/Y/0/R/0/B/0/W/0/M/0/C/0/A/0/Y/0 /D/0/3/0/9/0/8/0/X/0/P/0/F/0/I/0/0/0/E/0/B/0/7/0/Z /0/R/0/A/0/1/0/2/0)
- Private Key : A 33-Character String used for signing transactions (e.g.,
M/0/C/x/P/1/Y/1/R/1/1/W/1/ M/1/C/1/U/1/1/J/1/Y/1/R/1/B/1/W/1/M/1/C/1/A/1/Y/ 1/D/1/3/1/9/8/1/X/1/P/1/F/1/I/1/V/1/E/1/B/1/7/1/ Z/1/R/1/A/1/2/0)
Using Just A Public and Private Key to Send Coins
To Send Coins From An Address Using Only A Public and Private Key, You’ll Need To Use The Following Steps:
- Get your public and private keys : You can get your public and private keys by logging in to your Bitcoin account on a local node (e.g.,
Bitcoin-CLI GetNewaddress).
- Choose an exchange or recipient address : Select a recipient address that you want to serve coins to.
- use the BCC command line client : run the following command to create a new transaction and sign it with your private key:
`Bash
BCC -Q Public_key Private_Key -From Address
`
Replace ‘Public_keyWith Your Actual Public Key,Private_KeyWith Your Private Key /1/1/J/1/Y/1/R/1/B/1/W/1/M/1/C/1/A/1/Y/1/D/1/3/1 /9/1/8/1/x/1/1/F/1/I/1/V/1/E/1/1/7/7/1/Z/1/R/1/A /1/1/2/0), and Address With the Recipient Address.
- Create a Send Command
: Replace
`Bash
“TXID = 1234567890ABCDEF00 \ n \
version = 1 \ n \
nonce = 1 \ n \
SIZE = 1000 \ n \
payload = … (Your Data Transaction) “
`
Replace 1234567890ABCDEF00 with a unique transaction ID. The other fields are optional and dependent on the specification transaction you’re creating.
Example Use Case
Suppose you want to Send 10 BTC from your address M/0/C/X/P/1/1/R/1/B/1/W/1/M/1/C/1/U/1 /1/J/1/Y/1/R/1/1/W/1/M/1/C/1/A/1/Y/1/D/1/3/1/9 /1/8/1/X/1/P/1/F/1/I/1/V/1/E/1/B/1/7/1/Z/1/R/1/A/1 /1/2/0 to your address M/0/C/x/P/10/Y/0/R/0/0/W/0/M/0/C/0/U/0 /L/0/J/0/Y/0/R/0/B/0/W/0/M/0/C/0/A/0/Y/0/D/0/3/0/9 /0/8/0/X/0/P/0/F/0/I/0/V/0/E/0/B/0/7/0/Z/0/R/0/A/0 /1/0/2/0c.
In this example, theSend_CommandString is:
Bash
“TXID = 1234567890ABCDEF00 \ n \
version = 1 \ n \
nonce = 1 \ n \
SIZE = 1000 \ n \
payload = … (Your Data Transaction) “
`
Note : This is just a basic example to illustrate how you can use only a public and private key to send coins. In practice, you should always verify the signature of the transaction using your private key before swing it.
I Hope this Helps! Let me know if you have any questions or need further clarification on Bitcoin or BCC command line client usage.
