What is Tamper-Proof?

Tamper-proof is the characteristic of a blockchain network's ability to be immutable and censorship-resistant. Blockchains are designed to be immutable and free from manipulation in order to maintain the integrity and transparency of the system in a trustless manner without the need for centralized authorities. Once data (e.g., transaction history) is uploaded onto a blockchain, it should be unalterable so that malicious actors cannot modify the transaction history of a blockchain to potentially steal cryptocurrency or alter the network records.
