Re: [bitcoin-dev] BIP proposal: NODE_NETWORK_LIMITED service bits

Sorry again, is this discussion really serious? In this thread, previous ones or others, the level of approximation is obvious, often shadowed by useless maths/papers and strange calculations that are not helping, at the end nobody knows what would happen "if", how far the chain can roll back,

Re: [bitcoin-dev] BIP proposal: NODE_NETWORK_LIMITED service bits

It probably should be stated in terms of what you're promising to do-- 288 and 1152 blocks, not what we hope it will accomplish. Then advise clients to use peers with headroom because their estimates could be wrong and reorgs. Reorgs aren't the only concerns that drive larger numbers: The peak

[bitcoin-dev] BIP proposal: NODE_NETWORK_LIMITED service bits

Hi Currently, pruned peers have no way how to signal their (valuable) service. A BIP proposal to improve this (draft): https://github.com/jonasschnelli/bips/wiki/NODE_NETWORK_LIMITED-BIP-DRAFT Feedback is highly
