Blockchain snapshots to speed up first sync

can this be used to sync the entire blockchain?

Lets say if you decide not to go with pruned?

This will be for pruned, about 1000 blocks I would say

Ideally we make use of IPFS to facilitate. I've added an issue for this #159

I wonder if:

  1. We start from the same copy of the blockchain,
  2. Run it on multiple bitcoin nodes,
  3. Stop them all after exactly the same block

Will the contents of blocks/ and chainstate/ be exactly the same? 🤔

Would allow for at least some level of auditability.

That way we could, ex:

  • Host full, archival chain until block X,
  • Host pruned recent chunks

That way anyone willing to audit our "fast-sync" chunk would start from our archival part, setup bitcoind to the same level of pruning, stop bitcoind after a specified block and compared their own state with the chunk hosted by us.

Gotta investigate that.
