Proof of Work #59

More next week… :)

Bitcoin & Friends

Optech on Bitcoin [ed: sign up for their newsletter too! it’s great!]

  • Help test Bitcoin Core 0.18.0 RC2: The second Release Candidate (RC) for the next major version of Bitcoin Core has been released. Testing is still needed by organizations and experienced users who plan to run the new version of Bitcoin Core in production. Use this issuefor reporting feedback.

    Spy node ban list updated: some IP addresses are performing various attacks that are likely aimed at monitoring transaction propagation so that they can attempt to determine which nodes originated which transactions. To help node operators refuse connections from those IP addresses, Gregory Maxwell maintains a ban list that can be imported into Bitcoin Core and compatible nodes. There is absolutely no need to use this centralized list—your fully decentralized node will attempt to connect to a diverse enough set of peers that it should establish at least one honest connection—but using this ban list may reduce the amount of traffic you waste on spy nodes and other bad actors. The list comes in two formats, one for use on the command line with bitcoin-cli and one that can be pasted into the debug console of Bitcoin Core GUI. The blacklisted IP addresses are banned for one year and Bitcoin Core will remember the bans between restarts, so you only need to import the list once. Note: some users have reported that the ban list may exceed the maximum buffer size for the GUI on some platforms, requiring pasting it in chunks of about 250 entries each in order to load the whole list.
