React Js Validate a Bitcoin Address
React Js Validate a Bitcoin Address:To validate a Bitcoin address in React.js without using a library, you can create a function that checks the address's format and verifies its integrity using regular expressions and cryptographic methods. First, ensure the address matches the standard format (starts with '1', '3', or 'bc1'). Then, decode the base58 or bech32 address and validate the checksum. Utilize hashing algorithms like SHA-256 and RIPEMD-160 to verify the address's integrity. Additionally, perform length checks and character validations. If the address passes all criteria, it is considered valid; otherwise, it is invalid. This custom validation approach in React.js ensures Bitcoin address authenticity without relying on external libraries.

How can you implement Bitcoin address validation in a Reactjs?
This React.js code creates a Bitcoin address validator. It consists of an input field to enter a Bitcoin address, a "Validate Address" button, and a message to display whether the address is valid or not. The code defines a function to validate the input using a regular expression specific to Bitcoin addresses. If the input matches the pattern, it sets isValid to true, indicating a valid address, and displays a green message. If the input doesn't match the pattern, isValid is set to false, and a red message appears to indicate an invalid address
