    The pages blockchain, bitcoin, high performance distributed ledger, Ethereum, smart contract, virtual machine, all apparently created by the same person, seem off-topic for the nLab. At least some of them should certainly be deleted, or at least moved to the zoranskoda namespace.

    I agree that these entries are not a good look in their present state, though the topic of most of them could in principle be worthwhile here.

    For the moment, I’ll suggest that we:

    • keep entry titles “blockchain”, “virtual machine”, “smart contract” (and hope that somebody finds the energy to improve on them)

    • rename “high performance distributed ledger” to just “distributed ledger” (and otherwise hope for the same)

    • clear “bitcoin” and “Ethereum” and move what is worthhile about their content to an “Examples”-subsection at blockchain.

    The entries are obsolete as this were created as stubs 6 years ago and the subject was then just emerging, and admittedly not in good state as in the final moment (early August 2019) when I was most active about the topic I got a blow from my main coworker in that area (you don’t know him) and I abruptly had to leave the field as a consequence. In fact, most of the literature in the field is even in 2024. terrible, most recommended books at most places are total bs, unbalanced, propagandistic, obsolete and unrealistic. I know how it should be approached but have no time nor energy for that any more. The versions in my personal lab are slightly updated later in comparison to first nlab versions but not nearly satisfactory. I may do a bit in future to improve but not in full capacity.

    The point of high performance distributed ledger was not to talk about distributed ledger (the latter is more or less the same as the blockchain, up to generality) but rather to list ONLY those projects which aim to high performance/scaling unlike say bitcoin which is notoriously slow and low capacity project. So renaming to distributed ledger would do no good. IN the meantime new hi performance projects appear, some are listed in the version in my personal lab.

    It is up to you to decide if you want bitcoin and ethereum blockchains as separate entries (like one has separately pages for some programming languages as opposed to general pages on programming/cs), definitely each of them has lots of important specificity in algorithms with respect to generic blockchains.

    I somewhat disagree with 1) that the entries are at all about cryptocurrency (if crypto is understood in this sense and not as cryptography, then I agree). Blockchain etc. have their worth even without any cryptocurrency attached and my interests AT THE TIME when I was writing this were completely out of cryptocurrency, and only about technology and scaling of that technology. This technology may play a role very much complimentary to AI – AI is a major threat to privacy and humanity and something is needed to control it, and tools of cryptography; POW, POS, sovereign identity, distributed ledgers for ownership data etc. are key to mitigate those issues with AI and with massive data collecting emerging everywhere.
