[WIP] First half of SPV - Not ready for merge #7

Closed hashbender closed 6 years ago

hashbender commented 6 years ago

This is a work in progress and is not ready for merge into master. I wanted to open this up so for review

This PR:

1.) Adds a command line parameter to enable SPV mode, which operates only on headers, i.e. a headers-only consensus. https://www.coindesk.com/spv-support-billion-bitcoin-users-sizing-scaling-claim/

2.) When SPV mode is active, the client only requests block headers and builds a consensus set based on those headers

3.) When SPV mode is not active, the node will be available to respond to both header-only requests and full block requests

TODO: This needs verification and rigorous testing.

This PR will be followed by a PR to implement the filterload and getdata methods, allowing for full SPV functionality.

Thanks for this. We merged some of this into our implementation for the 0.2.0 release.
