So currently every transaction costs around $101, of which $1 visible in transaction fees, and $100 invisible in mining reward (aka seignorage, leading to money supply growth of 1.7% p.a.).

To maintain current mining hash power, as the mining reward halves away to zero, every transaction would have to incur around $100 in fees.

> still allowing miners to generate a huge (and ever growing) revenue, while also enabling most of the planet to transact next to free

If blocks would grow 10x, the blockchain would grow about 50GB per month, every human being could do around 10 transactions in their lifetime, and those would cost around $10 each. I don't see how huge and growing revenue for miners is compatible with "next to free" transactions.

That was an interesting talk, thanks. Looks like with some optimisations they could support blocks of around 100 MB, yielding around 500 transactions per second. Would mean though that the blockchain grows by a few hundred GB every month.
