Proof of Work #44
|Eric Meltzer||Nov 1, 2018|
Welcome to PoW44 and hi from Tokyo! A lot of exciting stuff happened last week—Coda was open sourced, Zcash Sapling went live, Dharma announced Lever, a super easy way to access decentralized margin trading via their protocol, and the Sia hard fork happened at block 179,000. This week’s updates are worth a close read.
This update was slightly delayed because I received a very weird submission and some anonymous messages from a Signal contact explaining in fairly vague terms what it’s about. I was asked to share this on the anniversary of Satoshi’s Bitcoin whitepaper, and further asked not to share anything else for now… but I will be able to give a bit more context in future PoW issues. I will say that I am pretty excited about what this person or team is up to.
Bitcoin & Friends
Daniel from Grin
More preparations for Grincon0, our first conference taking place in Berlin on November 9, attendance is free but likely to cap out.

Jimmy on Bitcoin
Aviv from Spacemesh
On the developer side: We merged PR (listening port is now sent in handshake); Gossip is in testing phase in branch p2p-gossip, published gossip protocol design doc and completed code and heavily testing new black-box POET prover and verifier GO implementation based on the shared spec
We are also testing RPC api functionality in the Liberthon hackathon branch, working on the core proofs of elapsed time (POET) server go implementation by open source contributors, starting the POET protocol spec implementation (spec draft updated with more details) and starting to working on many Spacemesh App feature tasks by open source contributors. Join us here! Gitcoin funded several dev tasks to tip open source contributors with cryptocurrency.
Extensive work on the DEVNET, that could test system scenarios on our decentralized network is gaining momentum. This week we managed to create some basic scenarios that included interaction between several P2P nodes. PR #42 merged plus 8 additional merged PRs.
On the community side we announced the first Spacemesh NYC meetup - join us downtown next Thursday (RSVP for free), published Tal Moran CESC 2018 Spacemesh protocol slides, and hosted the Liberthon hackahton prep meeting at Spacemesh TLV hq! We are also hiring full time core developers in New York City!
JZ from Decred
Crazy week, to start things off, Decred was able to obtain a free listing on Binance, which was quite exciting. We see this as an affirmation of the fact that we’re a community run project that has an eye to building long-term value and are not overly focused on chasing listings in hopes of generating short-lived price spikes. As is usually the case, patience, discipline, and focus paid off.
Richard has put together a digest of the Politeia proposals we have
received thus far. Four of the six proposals should go into the voting phase this week after we push some updates here. All Decred stakeholders that have live tickets in the pool at the point the snapshot is taken will be able to vote.
Mainnet support has been added do dcrandroid and we should be tagging a beta
Johnny from Stellar

Izaak from Coda
We're very excited to announce that we've open-sourced Coda! This is a huge milestone on our path to making truly accessible cryptocurrency possible. A big thanks to everyone who helped us get here.
Paige & Zooko from Zcash
We were focused on last minute tasks for activating Sapling over the weekend. Including, but not limited to, updating docs, prepping safemode alert for non-Sapling nodes and making sure ecosystem services are ready to go! Full steam ahead for Sapling!

David and @tbenz9 from Sia
2 Nebulous repo were updated. 8 issues were created, 10 were closed. 11 MRs were merged.
GitLab users xurious, Shatnerz, MSevey, ChrisSchinnerl, lukechampine and DavidVorick had code contributions merged into Sia.
Sia version 1.3.7 was released, this release includes a small bug fix that is required for the hardfork scheduled for block 179,000 (expected to be Wednesday). If you rent space on the Sia network or run a Sia host please make sure you upgrade to Sia version 1.3.7 before Wednesday. More information about the fork and the exchanges supporting the fork can be found here.
Chris began working on transitioning the .sia file format from JSON to binary blob. This change will enable Sia to modify parts of the .sia file without reading and writing the whole file. It is expected that this change will dramatically improve the performance of having thousands, and potentially millions of files owned by a single Sia user, and allow Sia to scale to hosting very large single files (on the order of tens of Terabytes).
From external contributors: Shatnerz adapted the Sia-Ant-Farm repository (a sort of local testnet for developers) to comply with the new API password requirement and also corrected the path of its dependencies. Xurious corrected a vulnerability in the block headers validation. Thanks to both of them.
