Bitcoin QR codes: effective content guide
As a developer, you can know the importance of safe and effective communication in the development of mobile applications. A popular solution is to use QR bitcoin codes to share private keys or account information. However, several factors are used when choosing the correct content of this QR code. In this article, we will study which QR codes should have mobile bag applications and other barcodes scanners.
What are Bitcoin QR codes?
The Bitcoin QR codes, also known as bitcoin barcodes or QR codes with Bitcoin, are a type of QR code that uses a unique combination of characters to represent a certain Bitcoin address. These addresses are used to identify and verify user accounts in the Bitcoin Network.
Bitcoin QR Code The correct content selection
There are several factors to consider when designing Bitcoin QR codes:
1
Bitcoin URI scheme : The first two characters in the QR code are the Bitcoin URI scheme (a uniform resource identifier) that identifies the type of address shown. URI standard includes
- Private password or account information
: Depending on the case of planned use, you may want to include private keys or other confidential account information.
3
Public key : The inclusion of public key can help identify the owner of the account.
Bitcoin code suggestions QR
According to the usual best practices and uses, we recommend the following content for Bitcoin QR codes:
- Private key : The QR code in the first 32 characters includes private key.
- Account information : Use the Uris scheme as ".bitcoin or .blockChain » followed by your public key (for example, Bitcoin: 0x1234567890abcdef
) to identify the account.
3
Optional : Consider the option of including a selection label or description of the latest QR code characters.
Bitcoin URI scheme and example of a private key
Here are some examples of Bitcoin Uris schemes and its appropriate private key representations:
- Schema .bitcoin:
Bitcoin: 0x1234567890abcdef
. Blockchain Schema:Blockchain: 0x1234567890abcdef
Conclusion
When designing QR bitcoin codes, it is important to choose the correct content that balances safety and usability. Including private keys or account information in the first 32 characters of the QR code and using the URI scheme as "Bitcoin or .Bockchain », you can create effective and effective QR codes for mobile wallet applications and other barcode code scanners.
Code fragment
To illustrate how to generate Bitcoin codes with recommended content, we will use bitcoinaddress. Here is a simple code fragment that generates a QR code that contains a private key:
`JavaScript
Const bitcoinqr = ask ('bitcoinaddress');
Function geneeeqrcode (address, label) {
Const qrcode = new bitcoinqr ({{
Urischeme: 'Bitcoin',
Data: address,
ERRORCORTIONLEVEL: Bitcoinqr.eror_correction_l,
});
Return qrcode.generate (label);
}
// Generate QR code containing the private key of the account
Const accounts = '0x1234567890abcdef';
Consta tag = 'my account';
Genereeeqrcode (accountsss, label) .then ((qrcode) => {
Console.log (qrcode);
});
`
When complying with these guidelines and using this example of a code passage, you can create effective Bitcoin QR codes that safely show private keys or account information for mobile wallet applications and other barcodes scanners.
