If one can prove that blockchains are extremely expensive to revert, then one can be assured that they will be extremely expensive to revert for any. Anti-censorship and Finality It is important to note that the above by itself does not prove that censorship is extremely expensive all on its own.
I hope the reader might begin to understand that censorship corrupts the very message that censors wish to expurgate. Then, B can prevent A from triggering the force-liquidation clause. Of course, some degree of altruism is required for this kind of cost strategy to have any effect - if no one was altruistic, then everyone would simply anticipate being censored and not include any undesirable transactions in the first place, but given that assumption it does add substantial costs.
Children can find this in their Sunday school churches; decent human beings can read this at any public library.
The simplest way to get around the mechanism is for validators to simply collude and start requiring senders to send t, p and q alongside c, together with a zero-knowledge proof that all the values are correct. This applies to religion as well it does to any form of language or art regardless of how obscene or benign it may appear.
One can even make the process more extreme: Although lots of work has been done in cryptoeconomics in order to ensure that blockchains continue pumping out new blocks, and particularly to prevent blocks from being reverted, substantially less attention has been put on the problem of ensuring that transactions that people want to put into the blockchain will actually get in, even if "the powers that be", at least on that particular blockchain, would prefer otherwise.
However, what we can try to do is one of two things: This indicates a lack of faith in the regulatory procedure, and an unwillingness publicly to defend decisions or the merits of specific works. One can use the extended Euclidean algorithm to compute modular inverses in order to run this calculation backwards.
The Problem of Censorship Posted by Vitalik Buterin on June 6, One of the interesting problems in designing effective blockchain technologies is, how can we ensure that the systems remain censorship-proof? In the later stages, the censorship may even be done in such a careful and selective way that it can be plausibly denied or even undetected.
Bloomberg publishing some data feed into their blockchain contract.

And why? This censored Holy Bible verse raises the question. Problems of Censorship • Lack of clarity and transparency about rules and processes Timelines, guidelines and other information are not always readily available; where they are, wording can be vague, and decision-making processes obscure.
5 Current issues of ‘Internet censorship’: bullying, discrimination, harassment and freedom of expression 6 Some regulatory challenges 7 Are current regulatory responses sufficient and appropriate?
Censorship of differing opinions allows society to blindly follow the current popular opinion until it's overtaken by a new one. So the problem with censorship today is the way we use it. We are using it to get our way, rather than protecting us from harm.
