Blockchain security is primarily defined by how difficult it is to alter or tamper with legitimate transactions recorded on the chain. This resilience stems from cryptographic hashing, distributed consensus mechanisms and the immutability of past blocks, all of which make unauthorized changes computationally expensive and easily detectable. A public key acts like a digital address that others use to send you cryptocurrency, while your private key is a secret code that allows you to access and control your funds.

New altcoins are continuously being created in a constant evolutionary battle for use case value.

Therefore, changing a single transaction would require recalculating ancestor blocks via gaining control of the majority of the network’s computing power (in PoW) or staked tokens (in PoS).
