Proof of Work #57
Hi from Boston! The MIT Bitcoin Expo is a student-run conference put on by the MIT Bitcoin Club, and is one of the few conferences I go to every year. I’ve got a free ticket to give away to a PoW reader. Whoever first responds to this tweet with “PoW” gets it! Malformed transactions will not be accepted.
Some housekeeping: I fixed the weird DNS bug that killed commonapp.proofofwork.news so you can now go there and fill out a simple form to simultaneously apply for a job at all the projects in PoW plus some other cool ones like Shapeshift, Coinbase etc. This tool will be getting way better over the next month, but when it died a surprising number of people yelled at me, so apparently it’s getting used now too!
I’m in the process of writing up a few long form pieces but nothing’s ready for this issue—in the meantime, I’ve found this ongoing series about the weird arb opportunities between different Tether clones to be really interesting.
If you are coming to the MIT Bitcoin expo this weekend, please hit me up on Twitter or just say hi at the conf! Would love to meet any readers there.

James from Summa
This week we released riemann-keys, a simple HD wallet library in Python.
Our Bitcoin light client, riemann-zeta, is getting a major upgrade to support transaction history
light client + keys + tx building = multi-chain wallet :)
Tony from Kadena
We're adding more functionality to our Pact smart contract language for interoperability. On track for Testnet launch of Kadena's public blockchain, Chainweb, at the end of March 2019.
Merged support for multiple key curves in a single transaction, including Ethereum ECDSA address formats, which opens the path to ERC-20 interop and ledger transfer to FungibleAsset tokens on Chainweb.
Merged programmable governance for customizable security primitives that allows module governance to be determined by code, and not just keysets. This allows for different participants to have varying levels of access in multiple signature scenarios.
Monica Quaintance gave a presentation on Chainweb and smart contracts at LedgerFest hosted by Blockchain @ Columbia.
Marie Leaf spoke about smart contract security and scalability at DeveloperWeek Bay Area.
Aviv from Spacemesh

JZ from Decred
Some good news for iPhone users, dcrios is now on TestFlight. Bug reports are welcome. Over the coming weeks it should approach parity with dcrandroid in terms of stability.
A new issue of Politeia Digest was released covering the most recent proposals, we're also super happy to announce that the stakeholders approved marketing and events budgets for the remainder of 2019. Dev budgets will be following shortly along with a proposal for converting Decred into a full DAO.
Our inaugural meet up for the Decred community in San Francisco will be taking place on March 6th. Decred dev Luke Powell will be presenting along with Chris Burniske and Alex Evans from Placeholder.
There will also be another special event on March 12th held at the OKCoin HQin SF featuring our project lead Jake Yocom-Piatt along with Chris Burniske (that guy is everywhere) called "The Next 10 Years: Crypto Boom, Bust, or Buidl?"
Johnny from Stellar
General: Fee Stats were launched in Horizon; it's necessary for handling Surge Pricing by any implementation that submits transactions.
Core: Getting closer to 10.3.0, ETA for snapshot (and testnet) is Mar-04, with a release planned Mar-14. Our focus will be on how we write to the ledger, with a 10x speedup on our low-end machines to join the network (from 100 minutes to 10 minutes).
Core: Next up is shifting to 11.0.0, with a focus on protocol changes (CAP-0005, CAP-0006, limits, etc.).
Horizon: Released Horizon 0.17.3, changelog: failed transactions, tools for surge pricing. Horizon Go SDK is being actively redesigned.
Kelp: Improvements mentioned by partners in the ecosystem.
Izaak from Coda
Snarky has a beautiful new monad-free interface thanks to Matt. Check out an example here (in ReasonML syntax).
Avery has started the initial work on our desktop wallet.
Rebekah implemented this map described in this paper from a field into an elliptic curve defined over that field. It's an essential component for an efficient group-valued random oracle, which is needed to instantiate Bowe and Gabizon's SNARK.
There were many robustness improvements to our implementation of Ouroboros Praos, including an amazing sequence of bug fixes by Corey.
Paige & Zooko from Zcash
Progress implementing Sprout -> Sapling migration tool
New ZIP draft for prohibiting negative shielded value pool [ed: this would make it impossible if someone had indeed exploited the previous bug to inflate the old shielded pool for them to actually move more coins than should exist into the transparent pool]
Documentation and internal testing on lightwallet Android reference app
