Definition
Censorship resistance is a network's ability to process valid transactions regardless of their origin, destination, or purpose, with no party able to block, reverse, or blacklist them. In Bitcoin, any node can relay a transaction and any miner can include it in a block, so suppressing a payment would require coordinating against a globally distributed, permissionless set of independent participants, which is practically impossible.
How the network earns the property
Censorship resistance is not declared, it is produced by decentralisation. Because hashrate and validating nodes are spread across many jurisdictions and operators, there is no single switch to flip. If one miner declines to include your transaction, another will, drawn by the fee. Even a miner that ignores certain addresses cannot stop those transactions from confirming through everyone else, and cannot retroactively erase confirmed history without out-competing the entire honest network's proof of work.
Why miners matter for it
The geographic and ownership distribution of mining is load-bearing for this guarantee. Concentrated hashrate weakens censorship resistance, which is one reason a healthy, dispersed mining ecosystem, including independent and home miners, has value beyond profit. It keeps transaction inclusion genuinely open.
For the individual, censorship resistance only fully accrues when you hold your own keys; funds on a custodial platform can still be frozen by that platform. Pair this concept with self-custody and counterparty risk to see the complete picture.
