Did you know that changing just one letter in a Bitcoin transaction completely changes its fingerprint?
Bitcoin transactions are hashed using SHA-256, a one-way function that ensures data integrity. Even the smallest change in input causes a completely different output, known as the avalanche effect.
Example:
SHA-265 (hello)=2cf24d
SHA-265 (Hello)=185f8d
This property makes Bitcoin transactions tamper-proof—if even one bit changes, the transaction becomes invalid.
