[bitcoin-dev] Bitcoin Core and hard forks

[Eric Lombrozo]

I think it’s pretty clear by now that the assumption that all nodes have pretty similar computational resources leads to very misplaced incentives. Ultimately, cryptocurrencies will allow direct outsourcing of computation, making it possible to distribute computational tasks in an economically sensible way.

Wallets should be assumed to have low computational resources and intermittent Internet connections for the foreseeable future if we ever intend for this to be a practical payment system, methinks.
