Private blockchains are incentivized to adopt public blockchain architectures because public blockchains are most economically vetted.
- wslh 9y agoNo, private blockchains can scale better than public blockchains for obvious reasons: they are trustful. Regarding private blockchains growing to public trustless blockchains, that is not a trivial problem. There are new blockchain models that are being promoted (e.g. IOTA, EOS, NEM) which have not being studied enough by consensus researchers.
- jaekwon 9y agoTendermint works great for 4 to 300 validators, and with the Cosmos delegation model, many more stakers can participate. So yes, it's not a trivial problem, but Tendermint is solving it.
- wslh 9y agoTendermint is not solving the problem I pointed before because it is not trustless, you are trusting the validators.
- sunnya97 9y agoIn PoW, you are trusting the miners.
- wslh 9y agoI am not talking about PoW specifically but about the new research that Bitcoin opened, including new consensus systems in trustless networks. The community knew how to build distributed systems in trusted networks before Bitcoin.
- jaekwon 9y agoYes, there were many designs. I don't know of anyone who really applied traditional BFT networks into public blockchain architecture, however, until Tendermint. For example, who spoke or wrote of BFT fault accountability/attribution, and how it pertains to proof-of-stake models, before Tendermint? There was also the 2011 paper that lamented the lack of good open-source middleware for BFT algos. Tendermint solves that engineering problem as well.
