Proof of Work #46
|Eric Meltzer||Nov 13, 2018|
Hi from Shanghai! A lot has happened in China since I was last here. Hong Kong recently announced official policy around licensing custody solutions and exchanges, which appears to be a pretty big deal and somewhat underreported. The regulation is official but is open to further modification, which is probably necessary because some of the provisions are fairly unreasonable—for example, exchanges in HK are required to have fully separated cold-storage accounts for each user, something which currently no exchanges anywhere do because of the extreme ops overhead. However the very existence of these regs is promising, and enables a bunch of HK based institutions (like the IBD divisions of large HK banks etc) to start to get in the game, something which our friends there say they have a large appetite for.
A lot of wealthy people in China are feeling extremely insecure these days as a result of things like the sudden disappearance of Fan Bingbing (when she reappeared months later, she paid a 100 million dollar fine for supposed tax evasion, and made a profuse public apology) and the word on the street is that many of them are starting to look at Bitcoin as a good hedge against total seizure of assets. Onboarding is pretty difficult because HNWs in China tend to have a lot of assets in corporate accounts which are completely prohibited from buying crypto, but there are several interesting workarounds that I’ll stay quiet about for now 😂.
More next week, thanks for reading!
Bitcoin & Friends
Daniel from Grin
The big update this week is that we arranged grincon0 – the first conference on Grin & Mimblewimble – to a full house at c-base in Berlin. Our anonymous project founder joined via ssh to deliver the opening of the conference through text-to-speech. YouTube video playlist of all the talks.
24 Pull Requests were merged in the past week, by 9 unique contributors.
While we've since dropped down in the ranks, Grin was briefly the #1 trending Rust repo on GitHub over a monthly basis.
More Grin info here.

Aviv from Spacemesh
JZ from Decred
Quick recap of Decred dev activity for October: 310 active PRs, 297 commits, 65.5K additions & 22.6K deletions across 4-9 devs per repo.
Bee has also pushed the latest issue of the Decred Journal, turns out we had a busy month, so busy in fact that we hit Reddit's ceiling for post length when trying to document it all. There's still a thread for discussion as usual. A few of the highlights were; the addition of a new corporate contractor to the project, a near doubling of the network hashrate as ASICs from new manufacturers begin to come online, and our first batch of Politeia votes concluding (more on that below).
Richard has provided an overview of the Politeia activity over the last week. The participation rates for the 4 votes that were held varied from 31-51% of all eligible tickets, the high end of that range is similar to what we have seen with our on-chain consensus votes and is quite encouraging for such a new system, it may even rise as we get the word out. On that note, the stakeholders apparently thought it was time for us to get some professional help (not that kind...), and a proposal to hire Ditto PR to represent the project was successful. Expect me to be replaced with someone who knows what they're doing imminently.

It’s great to see so many community contributors this week, if anyone is interested in getting involved in the code and needs help getting started please reach out to me (tbenz9) or a member of the Sia team.
Several large features were merged into Sia this week. Sevey’s “host whitelist blacklist” was finalized and merged into the master branch, along with, community contributor, Drexel’s “ability to overwrite existing file when uploading” merge request. These are both features that have been in development for several weeks and are now officially in the code.
Chris had his “Move SiaFile on-disk encoding from JSON to binary” merge request merged into the “unstable” branch which has been the main development branch for 1.4.0 features. Luke merged an exciting feature enabling partial downloads to be validated through “Merkle range proofs”.
As always, you can see a full list of code contributions, and development conversations here.
