Of course.
My proposal was just for the pruned nodes.
I.e. You would have a majority (maybe not even a majority required) of
nodes storing the whole blockchain and pruned nodes would store
"random" parts of the blockchain, according to the resources they
have, which would be organized as a DHT.

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.

I think John's actually has a point here. If we're judging the quality of a
protocol change by how compatible it is with DNS seeding, then we're c
You are welcome to optimise P2P addr broadcasts or develop better bootstrap

Sorry I should have used the word bootstrapping there rather than discovery.
But again I think that shows my point clearly. Centralized methods like DNS
should be used for as little as possible, just simple initial bootstrapping,

I think you too should ask yourself why you are putting so much effort into
optimizing a centralized service, the DNS seeds, rather than putting effort
into optimizing the P2P peer discovery instead. DNS seeds are a necessary evil,
one that shouldn't

Don't the seeds already set small times? I'm not sure we want these
responses to be cacheable, otherwise there's a risk of a wall of traffic

(generic comment on the discussion that spawned off: ideas about how to
allow additional protocols for block exchange are certainly interesting,
and in the long term we should certainly consider that. For now I'd like to
keep this about the more immediate way forward with making the P2P protocol

Sounds like this part of Bitcoin (block sharing) would definitely benefit from
having a REST (HTTP) API.
REST-based web APIs are a common feature of most online services these days.
Makes writing other client services so much easier. Plus you get the benefit
of the HTTP ecosystem for free (HT

While I like the idea of a client using a DHT blockchain or UTXO list, I
don't think that the reference client is the place for it. But it would
make for a very interesting experimental project!

X most recent is special for two reasons: It meshes well with actual demand,
and the data is
That's true. It can be perhaps be represented as "I keep the last N blocks"
and then most likely for any given node the policy doesn't change all that
fast, so if you know the best chain height you can calculate which nodes
have what.

I'd imagined that nodes would be able to pick their own ranges to keep
rather than have fixed chosen intervals. "Everything or two weeks" is
rather restrictive - presumably node operators are constrained by physical
disk space, which means the quantity of blocks they would want to keep can
vary wit
Hello all,
I think it is time to move forward with pruning nodes, i.e. nodes that
fully validate and relay blocks and transactions, but which do not keep
(all) historic blocks around, and thus cannot be queried for these.
The biggest roadblock is making sure new and old nodes that start up are
