Proof of Work #50
One day in crypto, one year in the real world
Happy Year of the Pig! Huge amount of exciting stuff in this update, including a mega-update from folks working on Grin, Handshake inching closer to launch, and a revamp of DDEX after moving off of the 0x smart contract system.
Ethereum Classic, a fork of Ethereum that was created after the DAO incident which the main Ethereum chain rolled back, appears to have been the victim of a 51% attack. At the moment it’s unclear if there were any successful double spends as a result of the attack, but it’s yet another a wakeup call to all exchanges listing proof of work forks with low amounts of chain security that the cost of doing so may very well exceed the benefits.
I had a really fun meeting with one of the folks at Cloudflare about potential ways that Cloudflare could support Handshake for resolving HNS domains and/or improving the security picture of DNSSEC. While not at all cryptocurrency related, I was blown away by all of the cool things Cloudflare is working on behind the scenes to keep the internet free and difficult to censor. I predict that over the next few years, a plethora of technologies including combination of techniques based on domain fronting, mixnets and onion routing, blockchain-based domain resolution a la handshake etc will lead to the internet being extraordinarily hard to censor. One caveat I’d mention here is that if you are a government that is OK with just wholesale blocking huge sectors of the public web (e.g. China) almost none of the above techniques can do much to stop you. However in more liberal states where blocking huge swathes of internet traffic isn’t an option, we’re getting closer and closer to an uncensorable internet.
Bitcoin & Friends
Daniel from Grin
25 Pull Requests were merged in the past week, by 11 unique contributors.
Lots of activity from @yeastplume in preparation for mainnet:
GPU memory reductions discovered that have led to lower GPU minimum requirements. @tromp has built miner plugins that supports these and these are now merged in grin-miner.
OpenCL miner for Cuckatoo31 merged by @hashmap. Cuckaroo up next.
Notes from last Governance meeting. No genesis block message. Non-binding polls for mission statement, currency ticker, and symbol is conducted on the forum and decisions will be made in next meeting.
March-Aug 2019 funding campaign for @yeastplume kicked off and accepting donations.
Grin London Meetup on Tuesday Jan 8 - come and say hi!

Published Hare protocol detailed flow chat
Added support for orphan blocks as preparation for new Tortoise protocol
Did our first core dev community sync live on Youtube. Watch to learn about what the core dev team is working on
JZ from Decred
Dcrandroid has a release candidate out. As a reminder, our mobile wallets use the P2P network instead of relying on a centralized server; maximizing user privacy and security, because that's just how we roll.
A bug bounty proposal from community member Degeri has passed on Politeia. It's been pretty great to see high quality proposals from people that have a proven track record of deliverables. The stakeholders so far have not been shy about voting down things that are poorly conceived or profligate. More detail on what's been happening with Politeia can be found in issue 9 of the Politeia Digest.
Johnny from Stellar
We're going to skip this week - we had a lot of folks on vacation for the holidays, and look forward to providing larger updates as of next week!
Izaak from Coda
First and foremost, we have completed the initial implementation of "succintified" Ouroboros Praos, running for hundreds of blocks before hitting a snag. Over the next few weeks, we'll be working out the bugs and testing rigorously. We're very excited to share what is essentially the most sustainable and scalable blockchain ever implemented!
The implementation of the ate pairing in snarky is complete, an essential component for recursive composition in our new highly optimized snarkitecture.
We welcome Matthew Ryan to our team. Matthew is our first engineer working solely on snarky, making it easier to use and more efficient. He's already done some great work on macros to improve the developer experience and a flame chart generator for profiling R1CSs.
Finally if you haven't already, check out this blog post from Coda engineer Brandon Kase on the data structure we use to achieve both excellent latency and throughput in Coda.
Paige & Zooko from Zcash
Before the holidays, we elaborated on some of the details regarding Sapling’s improved proving time for shielded addresses in Reduced Shielded Proving Time in Sapling.
We also shared the first of a short series on Zcash marketing efforts in 2018 Zcash Marketing: Year in Review. We posted the second installment this morning titled Quarterly Update: Perspective on the Market Evolution. The last of this series is planned to go out next week so stay tuned!
Diego and Riccardo from Monero
Some Monero community members (including the Monero Research Lab) have started a new series called "Breaking Monero" where we go over weaknesses of the protocol. You can watch the introduction here: https://youtu.be/WOyC6OB6ezA

Zaki from Cosmos
Game of Stakes is going really well. We've seen a rounds of low hanging fruit attacks on the mempool and adaptation with defense. The network is working well crossing 30k blocks. We continue to learn a lot from the stress testing. We planning an upgrade hard fork. The best place to watch action is Stargazer, Hubble and BigDipper.
We are mostly in the mode of polishing the code for the mainnet launch, preparing features for the first post launch upgrade. We strongly recommend looking at our F1 proof of stake distribution spec. It can offer major user experience improvements to any proof of stake blockchain.
We disclosed a critical vulnerability on the Cosmos SDK this week. If you are using the SDK or Tendermint in production, please get in touch so we can improve our coordinated disclosure posture.
Kate and Dean from Agoric
Happy New Year! This week we worked with RMIT to release a medium post by economists Chris Berg, Sinclair Davidson, Jason Potts and our very own Bill Tulloh. It’s on “nanoeconomics,” meaning a layer below microeconomics, including a market in computational resources. This builds on the concepts in the original Agoric papers by Mark S. Miller and K. Eric Drexler. R

Coulter from MakerDAO
Dai has turned 1! As of mid-December, there are 77M Dai in circulation, 1.5% of total ETH supply locked up in CDPs, 5000+ CDPs have been opened, maintained the peg despite a 90% drop in the price of ETH, and have over 200 integrations & partnerships. #HappyBirthDAI
After launching the re-designed CDP Portal this fall, we've now translated it to Chinese, along with the imToken 2.0 wallet building the CDP Portal directly into their app. The MakerDAO website will be fully translated into 10+ languages in the coming days.
MakerScan.io was released by a team from our community. It's quickly become one of the best resources to track CDP metrics or get alerts on your CDP. They even created a telegram bot @MakerScanBot for those interested.
MKR holders voted to decrease the stability fee, going from 2.5% to 0.5%
Dai and MKR are listed on Coinbase Pro!

Doug from Livepeer
The minimum viable implementation of Livepeer's Streamflow scaling proposal, including minimum viable probabilistic micropayments, is now feature complete. Next step is internal integration testing and an internal test network targeting 100 concurrent video streams, at less than 5% overhead for cashing payments.
8 months since launch, the Livepeer network is on the verge of 25% actively staked participation. The target is 50%, before the network begins to automatically alter the issuance rate to maintain the target, which is expected to occur in late 2019.

Published the retrospective "FOAM in 2018, a Year in Review"
Completed the first game on the FOAM Map, a Holiday Treasure Hunt. For 10 days a riddle about a Point of Interest was released, the birthplace of Alan Turing for example. The first Cartographer to add the correct point received a unique NFT of the building, designed by Blockcities. This game resulted in great community engagement and excitement over the rewards and was a fantastic learning experience for future games.
Placeholder Capital published an excellent post, "The Cryptoeconomic Circle" exploring the relationship between miners (the supply side), users (the demand side), and investors (the capital side) using FOAM as one of the example networks.
