# Raw transaction API example work-through
# Send coins to a 2-of-3 multisig, then spend them.
#
# For this example, I'm using these three keypairs (public/private)

Squashing redundant tx data in blocks on the wire

Sparse blocks

  • exchange priority policies in peer introductions
  • assign unique sequential IDs in the order the transactions were inved (per peer) receiving a getdata for a tx updates last-known-peer-received inv to all invs up to the one referenced
  • include ID-last-received, last-known-peer-received in sparse block
  • reference txes in sparse block by index in receiver's prioritiziation with peer's sent invs up to ID-last-received and sender's prior invs up to last-known-peer-received

An OkHttp interceptor which does OAuth1 signing. Requires Guava and Java 8, although those dependencies wouldn't be too hard to break if you didn't have them.
