Transaction Censorship Resistance
Transaction Censorship Resistance is the ability of a blockchain to process any valid transaction regardless of the sender's identity or the content of the message. This is a fundamental feature of permissionless networks, ensuring that no central authority can block users or freeze funds.
Censorship often occurs at the validator level, where nodes may choose to exclude certain transactions to comply with regulations or due to external pressure. Resistance is maintained by ensuring that there are many independent validators globally and by implementing protocols that make it difficult for any single actor to filter transactions.
It is a core tenet of the cryptocurrency ethos and a major point of contention in the intersection of decentralized finance and global law.
