Nice, Andrew.
Just one minor point. SPV clients do not need to maintain an ever growing
list of PoW solutions. BitcoinJ uses a ring buffer with 5000 headers and
thus has O(1) disk usage. Re-orgs past the event horizon cannot be
processed but are assumed to be sufficiently rare that manual
Bitcoind protects against this by storing the addresses it has learned
about in buckets. The bucket an address is stored in is chosen based on the
IP of the peer that advertised the addr message, and the address in the
addr message itself. The idea is that the bucketing is done in a randomized
way
Also (I am fuzzy on the details for this), Bitcoind will detect when a node
is misbehaving and (I believe) it will blacklist misbehaving nodes for a
period of time so it doesn't continually keep trying to connect to tarpit
nodes, for example.

You might consider the dimension taken by the cooperative mining approach of AI
Coin, an altcoin that will launch April 27. The coin is an embodiment of
principles described in my whitepaper last May, Bitcoin Cooperative Proof of
Stake.

Hi, so just a thought as my node relays addresses etc. If I wanted to really
slow down communication over the P2P network, what's stopping me from popping
up a heap of dummy nodes that do nothing more than exchange version and relay
addresses, except I send addr messages with all 1000
Interesting!
Thanks Kevin, I now need to research this and include such protections in my
node.

This is great to see.
