A feeless public ledger already exists, is transacting around the world, and has overcome spam attacks multiple times at this point: Nano, from one of the original developers of Bitcoin.
thanks, hadn’t heard of Nano before, it looks interesting.
I should correct to say a decentralized public ledger “free of transaction costs” is hard if not impossible. Nano seems to remove fees by having users engage in PoW (ie: cost of energy expenditure), so it is feeless but not free.
