Are decentralized blockchains immutable?
Could you please clarify for me if decentralized blockchains are truly immutable? I've heard that blockchain technology is designed to be tamper-proof, but I'm curious about the extent of its immutability. Is it possible for changes or alterations to occur, even in a decentralized system? If so, what are the conditions or scenarios that might lead to such modifications? Understanding the limitations and nuances of blockchain immutability would greatly assist me in my further research and analysis of this fascinating field. Thank you for your time and expertise in addressing this question.
