As I understand it, ERC-20 tokens are not mined, but premade. And for something like tiddlers, the blockchaing should be very, very, very short, even for popular tiddlers. So would this not mean that energy consumption is negiligable? Secondly, and more applicable to TW, you cannot change any previous data. > TW is essentially a data storage, and some of that data is likely to > change. Yes that change can be factored in to the chain, but sometimes data > entered is wrong or temporary and needs amending. > Well, my naive assumption was that the blockchaing could consist of the tiddler itself (or a hash thereof) and that you cannot change previous data (i.e the chain) but only add to it... which is done any time the tiddler is edited. The finesse here is that a tiddler could always be traced back, so if it says the author is Dragon we could see if it actually has been manipulated only by Dragon or someone else after Dragon. (and Dragon = Dragons public key). My point was that maybe blockchain could be a way to secure origin of a tiddler and trace its history - because this will be an issue when we eventually get a federated TW network going. Assuming we want traceability. Total misunderstanding on my part? <:-) -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
