The author argues that "timechain" more accurately describes Bitcoin because it emphasizes the fact that Bitcoin is a chronological ledger of transactions.
Well blocks that contian information or in this case transactions are linked to the previous one that is why they are “chained” together. I do get your point and I suppose timechain could be an alternative name however after many year sof using blockchain are we really to change it now?
The general public have not yet even fully understood what a blockchain actually is and now we want to change it already.
