This is our development update for 7 Jan 2019. Note that developers had taken a break and are just coming back after the Christmas and New Year holidays.

MTP

djm34 finalizing reference Nvidia miner to solve some remaining bugs.

Open source efficient AMD miner behind schedule due to ccminer tweaking. Likely to be competitive with Nvidia mining.

MTP academic research to relook into Q2, more pressing priorities right now.

Acknowledgement again to JCThePants work with Mintpond and open sourcing his work that enabled smooth MTP launch with pools.

Bitcoin Core Upgrade

Petr has an almost working version of Bitcoin Core 0.17 with Zcoin changes (working while on holiday). Extensive testing is still required.

Team decided to go ahead with Segwit mainly because MalFix and FlexTrans are not well tested and no glaring drawbacks beyond it being complicated.

Easier to merge Bitcoin core with Segwit

Will be a soft fork.

Sigma Update

Sigma development going well and unit tests are passing individually but for some reason when done together they fail.

Discussion of denominations and reminting change mechanism to prevent privacy leaks.

Sigma was coded to be similar in structure to existing Zerocoin code to allow easy upgrading to Bitcoin Core 0.17 because it was developed with 0.13

Team is more comfortable releasing Sigma first (which requires hard fork) and then later putting in core upgrade in separate release which is a soft fork.

Putta, Panu and Maria are now all assisting with Sigma unit tests.

Discussion on transition to continue allow Zerocoin spends (no time limit) but to stop new Zerocoin mints some time after Sigma is activated.
