I believe that if a majority of miners forms SPV mining agreements, then they are no longer affected by the block size, and benefit from making their blocks slow to validate for others (as long as the fee is negligable compared to the subsidy). I'll try to find the time to implement that in my simulator. Some hardware for full nodes will always be able to validate and index the chain, so nobody needs to run a pesky full node anymore and they can just use a web API to validate payments. Being able the "handle" a particular rate is not a boolean question. It's a question of how much security, centralization, and risk for systemic error we're willing to tolerate. These are not things you can just observe, so let's keep talking about the risks, and find a solution that we agree on. > >> If so, why is 8 MB good but 1 MB not?

But I believe that it is essential to not take unnecessary risks, and find a non-controversial solution. -- Pieter -------------- next part -------------- An HTML attachment was scrubbed...
