First time posting here, please be gentle. I'm doing a research project about blockchain timestamping. There are many such projects, including the fantastic OpenTimestamps. All of the projects essentially save some data in a block, and rely on the block timestamp as a proof that this data

The terms "simple ordering of blocks" and timestamp are essentially the same thing. On Jan 29, 2018 1:16 PM, "Neiman via bitcoin-dev" < bitcoin-dev@lists.linuxfoundation.org> wrote: > First time posting here, please be gentle. > > I'm doing a research project about blockchain timestamping. There
