Proof of Work #34

Very interesting week in cryptocurrencies. The team working on Grin has suggested they might be moving away from Cuckoo Cycle, to a hybrid PoW involving Cuckoo+Equihash. Whatsminer announced an absurdly good 16nm Bitcoin miner that puts significant pressure on Bitmain (as a sidenote, Whatsminer has a hilarious name in Chinese: “shenme/什么” means “what”, “shen ma/神马” is close to homophonous and means something akin to “wat!?” but literally means “legendary horse”) and Fomo3d was actually won, by someone who performed an extremely clever attack on the bots competing for the prize (h/t to Nic Carter for this one).

Also welcome back to PoW to 0x, who got dropped from a few issues due to dumb communication errors on our part, and are now back in full force.

Personally I’ve been heads down on something new and exciting which I’ll be able to talk about soon in a Proof of Work update. Thanks as always for reading, and please let me know if there’s any way I can make this more useful for you!

Bitcoin & Friends

Jimmy on Bitcoin

  • Big week with 9 Decred repos receiving commits. Among them were dcrdata which had 11 commits, politeiagui which also had 11, dcrd with 5, and decrediton with 9. In all likelihood, Decrediton will see v1.3 RC2 get cut next week as we’ve caught a few issues and polished it a bit since RC1. More details here.

Zac from Stellar

  • No update

Privacy coins

Paige & Zooko from Zcash

  • Now that Sapling-compatible Zcash 2.0.0 is out, engineering is laser focused on improved wallet support for 2.0.1.

  • Ecosystem team is reaching out to third-parties for Sapling activation readiness, Documentation team is working on Sapling dev docs.

  • Infrastructure team is working to make testnet as usable as possible for Sapling testing including explorer and faucet updates. More details here.

Diego and Riccardo from Monero

  • Monero has updated it's selection algorithm to improve the plausibility of ring signatures. Since we can't see the spending patterns of Monero users (privacy features and all), we look at Bitcoin and fiat spending patterns and try to choose a similar spending patterns for chosen outputs. We are constantly studying and refining this selection process to always choose plausible ring members. 

Smart contracting platforms

Evan from Ethereum

  • Truffle v5.0.0 beta released. web3js 1.0, bring your own compiler, and lots more.

  • Dogethereum bridge alpha to livestream on Sept 5th.

  • Geth v1.8.14 with Swarm v0.3.2: A full miner rewrite (!) with instant insertion of uncles into work packages which makes safer the current larger blocks.

  • Our ecosystem values progress and growth, so it puts resources to good use.  Thus, it’s raining grantsEthereum Foundation round 3. And ECF round 2. Plus Aragon round 2, as well as their update on rd1 grants. [ed note: excited to see the grant speed pickup. My biggest beef with most foundations is that they are too slow and stingy with grants, even when awesome opportunities are available. I whined about this to the ETH foundation folks and found that they felt the same way. Good to see action being taken!]

Finally, we’re working on fetching more data types, optimizing the data synchronization flow, and fixing various edge cases.

David from Sia

  • 2 Nebulous repos were updated. 1 issues were created, 0 were closed. 1 PR was merged.

  • GitLab user lukechampine had code contributions merged into Sia.

  • Lukechampine upgraded the Sia app for Ledger Nano S, that now reaches the status of beta software in this 0.2.0 release. Notably, the app is now feature-complete after improvements in security, as the transaction hash has no longer to be calculated in the computer. This means that using this hardware wallet should be safe even on a compromised computer. The app still needs to be extensively reviewed and audited before it can be released as a secure app, meant for the general public. The app can be checked and downloaded for testing here.

  • Not yet merged into the code, but there has been more work in progress: MSevey is improving the code related to streaming multiple files simultaneously and also made progress fixing the bug where renters could end up with duplicated contracts.
