      The #blockchain is not 'ceasing to be a neutral mechanical system.' It never was neutral. People always made political decisions that impacted others, & continue to do so. True of all blockchains. I could go on (for a while), but for now I will leave it at #codersasfiduciaries. https://twitter.com/TokenHash/status/963987749521866752 …

      Neutral: “not helping or supporting either side in a conflict or disagreement.” Certain aspects of a blockchain *are* neutral, eg, the that transactions are final & irreversible. If a small group of humans can tamper with the ledger & reverse txs, it is no longer neutral.

      See my work on the finality/irreversibility/immutability myth of blockchains. These cannot be viewed as absolute, given that the humans involved in the system can ALWAYS choose to change their minds. Human agency is always present. https://ssrn.com/abstract=2940335 …

      Nothing under the sun is *absolutely immutable*. Given enough energy, even Gold can be synthesized. When we say “immutable” we usually mean it’s *practically immutable*.

          I think people should just start saying 'tamper-proof'. Immutability creates too much confusion.

          isn’t “tamper-proof” also a relative term? 🤔

          yea.... you can prove it's been tampered with. A lot of good that does.

          Exactly. The point is not that they can never be changed ('immutable') but rather that it's hard to do so and that if this happens it is unlikely to go unnoticed ('tamper-proof').

          I like "tamper-evident."

          Replying to @angela_walch @finck_m and

          Tamper evident captures one aspect. The other material aspect is that these systems use financial incentives to secure data. So maybe try: "financially secured" data or, to describe the feature, "financially infeasible record malleability" (FIRM is a good acronym)

          I've been going with hard to change, but maybe "costly to change" (CTC) :)

          In the context of blockchains, BTC is immutable to the degree that creating & reversing the txs roughly costs the same amount of energy. This amount of energy *is* neutral: it doesn’t matter who you are, it will cost the same.
