Notes / short topics

Gmaxwell notes he’d still like to see separate testnet-defaulting binaries during the RC’s. Wumpus points at a PR he missed that makes it very easy to install a testnet client.

FIBRE announcement

0.13.0 rc1

background

The Bitcoin Core team is working towards 0.13.0 RC1. (full schedule)

There’s a few issues that need to be fixed for 0.13.0. Wumpus can’t build a release as gitian lxc building is broken as explained in this issue (the day after the meeting a workaround was found). For 0.14 we can switch to ubuntu 16.04 which has fixed this issue.

Sdaftuar has some PR’s open meant for 0.13.0 which lack some review, namely #8305 (headers sync issue), #8312 (mempool DoS post-segwit merge) and #8295 (mining code fixes post segwit-merge).

When testing the new hierarchical deterministic (HD) wallet MarcoFalke encountered an issue. Either being an error in his test code or an issue with IsMine(). If there’s no clear answer why this issue happens it’s better to disable the HD wallet for 0.13.

Before the end of the meeting Jonasschnelli already found the bug in the testcode of MarcoFalke. The fixed test will be included in 0.13.0.

FIBRE announcement

background

Matt Corrallo has announced his new relay network work that uses UDP and FEC, the current not really fully cooked software gets worldwide block propagation 99% of the time in less than 100ms over the fiber-path distances.

More info can be found on the website http://bitcoinfibre.org/

In his deployment he uses only cheap VPS’s. He’s trying to get other people to setup parallel networks and put up an extensive guide, including tracks for getting access to low latency connectivity between Asia en Europe.
