Proof of Work #53
Hi from a plane en-route to SFO! Why is JetBlue’s so so much faster than Uniteds? Is one ground-based and the other satellite?
Friends of the newsletter Sharon Goldberg and Ethan Heilman launched something cool this week, a trading protocol called Arwen that could be summarized as “lightning, but for trading” on testnet. Arwen allows traders to securely trade cryptocurrencies at a centralized exchange, without ceding custody of their coins to the exchange—BTC, LTC, BCH, ZEC as well as Ethereum and ERC-20 tokens. Today's testnet launch is for BTC, BCH, and LTC. A full protocol description is in their whitepaper. They have a partnership with KuCoin, which strikes me as a great first partner (decent liquidity, still mixed reputation and not somewhere big traders want to keep a ton of coins at risk.)
Sunday was Holocaust Memorial Day. I grew up in a household that was extremely left-wing but had a bunch of guns “because the ones who had guns at least got to fight back in Warsaw.” There’s a kind of sad understanding among Jewish people (especially the grandkids of survivors) that every few decades some government loses its mind and starts slaughtering an ethnic or religious minority that lost the dice toss. There’s a sad tendency among some Jews to insist on the unique badness of the capital H Holocaust over other holocausts and genocides, but unfortunately it was just one especially awful instance of a relatively common phenomenon.
One thing that gets lost in our rush to paint the Nazis as pure evil beyond any rational understanding is the financial motivation that was such an important driver of the Holocaust. At the highest levels, the Nazis were driven by the idea that they were “reclaiming” wealth that the Jews of Germany had “stolen” from honest, hard working Aryans. The campaign to rob the Jews of their wealth was astonishingly broad; the Nazi government worked with domestic and international banks to freeze accounts, with insurance companies to seize policy payouts, worked with real estate brokers to find and force to be sold at below-market prices land parcels own by jews, and instituted incredibly high exit taxes on the lucky (?) Jews that fled before things got really awful. The number of people who left with just a tiny bit of gold sewed into the linings of their coats was so high that it’s become a cliché. Of course, soon after that many of their friends and relatives wouldn’t even be allowed to keep the gold in their teeth.
When faced with an atrocity on the scale of the Holocaust, many of us have an impulse to turn away, to seek a simple explanation, to crack an inappropriate joke—anything to not have to think about one group of people systematically stealing everything from another group, and then murdering them in specially designed camps, men, women, and children. But that’s what happened, and similar things will happen again if we don’t address the root causes. These causes are diverse and I don’t wish to make it sound as though crypto is anything like a panacea for stopping genocides. But the financial aspect is truly underappreciated by most non-historians, and it is there that crypto truly shines.
Forget ICOs, forget allocating digital resources, forget gaming. The use case for which crypto is so insanely well-suited that it would take a fool to miss it is as a seizure-resistant easily transportable store of value. At mass adoption, this is a game-changer, as it will be well known that most people have a type of wealth that is deniable, anonymous, and extremely difficult to confiscate. But even way before we get anywhere near mainstream adoption, it will be worthwhile to try and get cryptoassets into the hands of the people who need them most, whether through airdrops, mining, or just enabling easy buys with fiat.
When I tweeted about this, I got a bunch of horrible DMs, but also some extremely moving ones from the survivors of genocide. I also got this really interesting reply:
Making it much easier for people to make the decision to leave is something that can save lives—its very very hard to go from “you own things” to “leave everything behind, or die.” This is the core reason I’m excited about crypto, and if any of you are working on things that make this use case more robust, please don’t hesitate to be in touch.
Bitcoin & Friends
David from Sia
1 Nebulous repo was updated. 9 issues were created, 20 were closed. 8 MRs were merged.
GitLab users lukechampine, ChrisSchinnerl and MSevey had code contributions merged into Sia.
ChrisSchinnerl implemented a method to recover file contracts associated with the recovery seed of the user. This feature is the key component for the file recovery from a user backup of the metadata, that 1.4.0 will feature, and the full file recovery from seed that 1.4.2 will include. This method retrieves contracts as long as the wallet is unlocked: (link). Additionally, he added the API endpoint
renter/initrecoveryfor triggering a re-scan of the blockchain that retrieves contracts on demand: (link)
MSevey continued working on the file repair revamping. Now file repairs are triggered to the folders with lower redundancy instead of on a file-by file basis: (link). He is also currently improving the routine that detects and repairs file chunks that are stuck in the repair process: (link).
Lukechampine made additional progress on the RPC protocol upgrade (the communications channel between hosts and renters).
The completion of the Release Candidate of version 1.4.0 approaches, with a few items remaining to be tackled: a bug in the repair process and 2 methods of the RPC protocol.

JZ from Decred
We're nearing final release of the Decred Android wallet, v1.0.0-RC3 has just been cut and pushed to the Play store for mainnet and testnet. Our mobile wallet uses true SPV through the P2P network as opposed to relying on centralized servers, making it pretty unique. As always bug reports are welcome.
Speaking of bugs, we're happy to announce that we just launched the Decred Bug Bounty program and we'll be paying up to $25,000 USD (in DCR) for discovered vulnerabilities. Degeri, who is running the program has described the rationale behind the initiative.
Since 51% attacks seem to be in vogue, Richard has published a piece outlining how Decred's multi-factor consensus (hybrid PoW+PoS) protects from this attack vector.
Johnny from Stellar
Stellar please send me updates, I and everyone reading this want to know what you all are up to.

Izaak from Coda
Paige & Zooko from Zcash
We created an “Encouraged Community Work” GitHub board for things that the Company can’t get to in the next 4 months that people in the community are likely to have the context t o work on.
This week Least Authority released details about the Private Periodic Payment Protocol, or P4, which aims to define the way in which subscription services can be funded using end-to-end private cryptocurrency payments. P4 incorporates the use of Zcash shielded transactions for private payments and leverages the Tor anonymity network’s onion services to radically reduce the amount of personally identifiable information (PII) available to merchants. In addition, P4 introduces periodicity to cryptocurrency payments by bootstrapping a secure channel between customers and merchants (using the SPAKE2-based "magic-wormhole" library) through which invoices can be delivered and paid.
More detail here.
