The annualized growth rate of bitcoin's chain state jumped from ~15% to ~28% over the last three weeks as inscription fever took off.

It will be interesting to see if the pace of chain state growth keeps up and what that means for the ability of people to run nodes in the future. Luckily, bandwidth is getting cheaper and high speed internet access is increasing, but it's hard to say what the long-term ramifications of 4MB blocks will be on the distribution of the network.

#Plebchain figure it out

Quoting growth rate as a percentage is misleading. Better to quote the projected absolute size in GB. The growth rate doesn’t compound, it’s linear. If every block is 4MB we can expect a max chain growth size of ~210GB per year

It was already a challenge. I’m extremely rural (by design) and refrain from services that can be lived without (tv services, home based internet, etc). I’ve managed to keep a node up and running with a tethered mobile device for transaction broadcasts, but.. keeping a sync is a challenge. I acknowledge I’m a fringe case for the US, but globally.. probably not. Bandwidth is the real concern.

It’s not hard to say, this is a very bad development. I don’t buy the argument that we need super complex Taproot, scripts, we are the block size they consume is even cheaper than other elements of the block space. I think we should immediately make the witness data more expensive, at least to be on par with the rest of the block space.

No. It will have (if anything) a net neutral effect on resource limited nodes (slightly higher relay bandwidth, slightly lower disk cost once we allow pruning witness below assume valid height, etc)

It will be fine. It will push developers into witness pruning and other optimized validating nodes

We should softfork merkle commitment to chainstate in every block that would be huge win for optimized nodes
