Re: [Bitcoin-development] Proposed alternatives to the 20MB step function

I've been following the discussion of the block size limit and IMO it is clear that any constant block size limit is, as many have said before, just kicking the can down the road. My problem with the dynamic lower limit solution based on past blocks is that it doesn't account for usage spikes. I

He also said that the equation for miners has many variables, as it should. There is no disadvantage if the network speed is the same between the miners. If there is a difference in network speed, the miner is incentivized to invest in their network infrastructure. 2015-05-31 23:55 GMT+01:00 Alex

i guess you look at the glass half full :) even though what you say is true, we should aim for wallets not to require those instructions, by standardizing these things in BIPs. let's hope bitcoin doesn't fail in standards as our industries have in the past... 2015-03-11 19:04 GMT+00:00 Jim

2014-04-10 Thread Ricardo Filipe
anyway, any kind of compression that comes to the blockchain is orthogonal to pruning. I agree that you will probably want some kind of replication on more recent nodes than on older ones. However, nodes with older blocks don't need to be static, get the block distribution algorithm to sort it

We would only end up with few copies of the historic data if users could choose what parts of the blockchain to store. Simply store chunks randomly, according to users available space, and give priority to the N most recent chunks to have more replicas in the network. You don't need bittorrent
