Proof of Work #77
|Eric Meltzer||Oct 23, 2019|
Good morning from Boston! A few unfinished thoughts from my Asia trip that I’ll expand upon in the next few issues:
In some cases, exchanges are the enemy. A few bad-actor crypto exchanges in Asia print coins out of nowhere to engineer pump-and-dumps which they directly benefit from. Neither projects nor whales are colluding here; the exchanges themselves are doing this on their own. I used to think decentralized exchanges were something that only hardcore crypto folks cared about, but in the absence of regulation, decentralized exchanges may start to be in more demand as retail realizes how some of the exchanges are fleecing them.
Bitcoin isn’t going anywhere, there are huge inflows to mining in China (setting up big farms, creating new ASICs, etc) despite the price coming down.
China seems fairly serious about a digital fiat project.
More next time! Thanks for reading.
Bitcoin & Friends
Jimmy on Bitcoin
Optech on Bitcoin [ed: sign up for their newsletter too! it’s great!]
Upgrade LND to version 0.8.0-beta: LND’s newest release uses a more extensible packet format, improves backup safety, increases watchtower client integration, makes routing more likely to succeed, and includes many other new features and bug fixes.
Upgrade to Eclair 0.3.2: Eclair’s newest release improves backups, makes syncing gossip data more bandwidth efficient (especially for non-routing nodes, such as nodes on mobile devices), and includes many other new features and bug fixes.
Review RCs: two popular Bitcoin infrastructure projects have issued Release Candidates (RCs) for the next version of their software. We encourage developers and experienced users to help test these RCs so that any problems can be found and fixed before their general public release:
Bitcoin Core 0.19.0rc1
Johnny from Stellar
Stellar is an open network for sending and exchanging value of any kind. Its global network enables digitization of assets - from carbon credits to currencies - and enables movement around the internet with ease.
On Monday, 10/28, at 1600 UTC validators will vote on whether to upgrade the public network to Stellar-core v12.0.0. If you run Stellar-core or Horizon, you should upgrade right now. It has a few big changes including:
- Node status monitoring improvements
- The introduction of a new operation that makes path payments symmetrical
- The removal of bucket shadows
- The end of inflation as we know it
On Wednesday, 10/30, at 0900 UTC there will be a testnet reset, which means everything will get wiped from the testnet ledger. If you are in the middle of something, make a plan to recreate any ledger entries you need, including accounts and balances. Read here for best practices when using the testnet.
Horizon 0.21.1 was just released on Thursday, 10/10. The big change: it includes support for Stellar-core v12.0.0! If you run Horizon, make sure and upgrade now.
Meridian, the first official Stellar conference, has an entire track of programming dedicated to developers. It’s taking place November 4–5, so if you’re interested in attending, grab a ticket. You can use the code 'STROOP50' for 50% off at checkout.
Izaak from Coda
Coda is the first cryptocurrency protocol with a constant-sized blockchain. Coda compresses the entire blockchain into a tiny snapshot the size of a few tweets using recursive zk-SNARKs.
Echo reduced memory consumption by 35% by replacing glibc's malloc with Jemalloc.
Avery got the Coda wallet working in Ubuntu.
Paul and Matthew have made and applied tools to enforce a versioning discipline across the codebase for all types that go on the wire.
Izaak is teaching an all-day Zero Knowledge workshop during SF Blockchain Week featuring closing remarks and a happy hour with Vitalik. You'll get hands-on experience programming SNARKs into your dapp - use code POW for 50% off any ticket (limited quantity). http://bit.ly/SFBWZKP
Paige & Zooko from Zcash
Zcash is a digital currency utilizing zk-SNARKs to enable its privacy-protecting properties.
Stanford PING and REJECT: Researchers at Stanford presented two types of active side-channel attacks against private (a.k.a. shielded) transactions in Zcash. This Security announcement has been shared earlier this month in the Zcash community forum. Be sure to upgrade your nodes to Version 2.0.7-3 immediately and discontinue use of older versions. Please note that the issue does not put funds at risk of theft or counterfeiting.
Other updates to zcashd core team:
Putting final touches on mempool DoS fix for 2.1.0 which we expect to come out soon
Putting final touches in librustzcash v0.1.0
Added “developer tooling” making it easier to work simultaneously on librustzcash/zcashd
Transitioning to scrum to help increase cycle time
Core Team current backlog
Dev-Infra team continues to work on updating/migrating Python2 code to Python3 as well as making several major Zcash components Docker compatible.
The reference wallet team has spent the past few weeks paying down technical debt and addressing security concerns.
handled all but one high-level security concerns brought up through internal review (sanitizing inputs, adding encryption between communication, etc.).
started to restructure the iOS and Android SDK so that there can be demo apps that showcase and isolate a specific functionality. Right now, the Android app looks more like a demo app--and it's not maintained to be stable. We've started on the iOS one!
added docker support and adding CI testing framework for `lightwalletd`. Now you can deploy a lightwalletd server with a simple docker file!
gotten feedback from multiple wallet partners on our sdk and lightwalletd server and we’re iterating based on that feedback.
In other wallet-related news, ZecWallet lightclient CLI is now available for beta testing on Zcash mainnet.
Workshops and events: Daira and Str4d will give two talks at an upcoming ZKProof Community Event in Amsterdam (10/28 - 10/29). Str4d's talk will be on Halo itself, and Daira’s will be an update of hir scaling proposal.
