Proof of Work #32
Hello dear readers, from rainy Boston.
I spent most of this week playing around with the Handshake testnet, bidding on names and trying to mine some testnet coins. Since we last talked, the Namebase team shipped a Chrome extension that allows anyone using Chrome to resolve decentralized names on the Handshake testnet! Once you’ve installed the extension, type “turbomaze/” into your address bar in Chrome, and you’ll see the Namebase CTO’s personal blog—kind of magical.
Why I’m so excited about Handshake is that it’s one layer in a stack of services that will eventually allow for completely “ownerless” (and therefore, unstoppable) websites. Imagine a blog hosted on IPFS with its DNS being resolved on Handshake, and the IPFS pinning fee being paid either in Filecoin if they manage to ship, or Bitcoin/zcash/whatever if they don’t. I was chatting with a dev working on a decentralized file-storage solution, and he told me that he lost the private keys to his testnet implementation and then just had to wait for his account to run out of money, because he had no way to take the site down! Proof of censorship-resistance indeed..
Mining is the most brutal part of the crypto world by far. It’s more zero sum, more competitive, there’s massive capex on the line for big players, and most of the interesting part is conducted in secret. A few months ago, there was a big kerfluffle when Bitmain announced ASIC miners for the Sia network, in a way that made the Sia community very suspicious and unhappy. The basic complaint was that Sia community consensus was that miners should be pre-announced so that purchasers of an ASIC could accurately forecast what they would be getting—Bitmain announced their ASICs a week before shipping them. At the time there was a huge rift in the community over whether Sia should make use of a secret feature on their ASICs that would allow them to fork away from the Bitmain ASICs but keep the Sia ones usable—in the end, there wasn’t adequate consensus, and the fork was not pursued. However, the aftermath of the Bitmain ASICs has wreaked havoc on the Sia community, and there appears to now be a solid community consensus towards activating the fork and in a sense “bricking” the Bitmain ASICs that would no longer be able to mine on the Sia network. It appears to me likely that this will go forward, which is a boon to anyone holding a Sia miner, and a small black eye to Bitmain on the eve of their IPO. Will be interesting to watch!
I’ve added updates from a really interesting off-chain scaling project called Celer, which I think will lead to people building a lot of cool stuff on Ethereum that currently can’t be done on-chain. I’ve also added a project called Berminal that is fairly different from anything else on PoW. I’m pretty skeptical of dAPPs, but I’m keeping on eye on these guys because they are building something that will test my hypotheses around using tokens to incentivize user behavior. Additionally, going forward the Bitcoin updates are going to be more substantial because we’re adding a second contributor to augment Jimmy’s already awesome coverage. Updates below!
Bitcoin & Friends
Jimmy on Bitcoin
Dandelion PR made. [ed note: Dandelion is a really cool feature that supports better transactional privacy on Bitcoin. Transactions are first broadcast to a single peer, and then after a random number of hops, “poof” like a dandelion and are broadcast out to all peers. You can read way more about it here]
Bitmain, BTC, BCH and IPO [ed note: a bearish look, but an interesting analysis]
Responsible Disclosure of BCH consensus bug [ed note: this is one of the most underreported and frankly insane stories in crypto. A bitcoin core developer, theoretically the ideological enemy of BCH, discovered a seriously gamestopping bug that could have caused a chainsplit, and instead of exploiting it responsibly disclosed it. Had he done otherwise, and perhaps opened a short at the same time, he could have profited immensely at the expense of all BCH holders. What a story]
JZ from Decred
The July issue of the Decred Journal has been released. There are tons of updates on development, marketing, media, and the broader Decred ecosystem. Be sure to check it out.
We tagged the first release candidate for both Decrediton and dcrd this week. RC1 for Decrediton introduces optional SPV support using client-side committed filters. Dave has written up a post detailing the many enhancements made to dcrd this cycle. Interested parties should download the appropriate binaries and take them for a spin.
Paige & Zooko from Zcash
Zcashd 2.0.0 (aka the first Sapling compatible version) is on track for release next week [ed note: sapling, the zcash update that massively reduces overhead on z-transactions making them doable on mobile devices, is going to be a Big Deal]
Getting ready for RustConf in Portland (come see us at our booth!)
Open Android developer position
More detailed update here on the forums!
Diego and Riccardo from Monero
Smart contracting platforms
Evan from Ethereum
No update [ed note: my fault, reminders went out late this week!]
Zaki from Cosmos
We are releasing Cosmos-SDK version v0.24.
Cosmos is the process of building the most complex staking and slashing state machines so far in blockchains. Slashing conditions are enforced against validators and their delegators. Fees and inflationary rewards are automatically distributed to delegators in protocol. The difficulty of testing the implementation of this complex machinery and conformance to specifications has led to a bunch of different decisions. On one hand, we've invested heavily in simulation and fuzzing approaches that have started to land in v0.24. On the other hand, we've decided to launch with simplified versions of the remaining state machine features.
Bill from Agoric
We updated the SES demo to fix an interesting vulnerability found by a new contributor.
Antonio from dYdX
Published an npm package and docker container to make interacting with the protocol easier
Completed security audits with SoHo Token Labs and CryptoFin

Brendan and Nadav from Dharma
No update [ed note: my fault, the reminder got sent late!]
Coulter from MakerDAO
Though it's been a tough week for crypto, Dai remained stable and saw it's highest 24hr volume all-time ($7.7m), providing safe harbor during a dip in the market. [ed note: honestly super impressive]
Announced an integration with The Ocean, bringing Dai into their platform.
Phil from MARKET Protocol

Dong Mo from Celer
We announced a partnership with L4 Ventures, in order to together define the standard for off-chain state channel scaling for Ethereum and also research cutting-edge topics in off-chain scaling.
We completed the UX and UI design for home screen and usage flow for on-chain part of cOS mobile, and implemented a local database for saving the above data and provisioning the UI.
We also finished the first workflow design of how a user interacts with off-chain dApps. This interaction can be seamlessly integrated with the on-chain workflow, but some more user study and tuning is needed.
We’re currently working on modularizing backend components and finalizing the design of cNode interface and of low-cost on-chain griefing flows. Implementation in progress!
Implemented the generic interaction layer between off-chain backend and blockchain.
Finalized the design of state persistence and recovery. Finished the implementation of the persistent datastore library that is platform agnostic. This will be used in cOS mobile and also cNode full Celer Network node. Integration into business logic in progress.
Proof of Liquidity Commitment mining prototype is in progress and we are doing some game theoretical analysis on what should be the dynamic algorithm to control the issuance of CELR token through PoLC mining.
Janine from Liquidity.Network
Resolved issue with the faucet which allows users to receive a small amount of Wei to experience the capabilities of the wallet without depositing.
We are also excited to announce the launch of our fortnightly community newsletter, where the community can keep up to date with Liquidity’s chronological achievements and events directly from the team. Please subscribe to the newsletter at the bottom of our website. A Chinese translation will also be available for our Asian community.
Crafting a Bitcoin token in Ethereum: Arthur has published with his co-authors at Imperial College London the latest design on how to make a Bitcoin token in Ethereum
Such novel techniques will significantly improve trustless cross chain capabilities. The whole blockchain ecosystem will benefit from such interoperability solutions, such that different blockchains will not only compete but rather develop healthy synergies moving the usability of blockchains to the next level.
Alexandra from Parity Technologies
