Proof of Work #33

Aloha from sunny Oahu, and the thirty-third week of this newsletter.

Last week I mentioned that the first exchange for Handshake domains, namebase.io had developed an open-source chrome extension that allows you to resolve handshake domains right now. This week they have entered private beta for the main exchange, so if you would like to help squash bugs and be among the first people to register decentralized domain names on the Handshake blockchain, you can email tieshun at namebase.io and ask to get a beta invite.

I’m putting together a small overview of the OTC bitcoin scene in China, which will hopefully run in the next issue. It’s a fascinating world of giant deals being executed on via immature infrastructure, and its a pretty opaque part of the scene. More on that next week!

JZ from Decred

  • Work is continuing on getting our 1.3 release out the door for the Decred CLI tools as well as Decrediton. Decrediton had 8 commits this week while dcrdata had 11, and dcrwallet saw 6 commits. dcrdata also has a new alpha (https://alpha.dcrdata.org/charts) which adds some nice charting features for things like historical ticket prices, transactions per block, etc.

  • We’ve been revamping dcrdocs as we gear up for the release of Politeia (https://docs.decred.org/governance/politeia/). Many people have had questions about the lifecycle of a proposal under the system, so we’ve tried to document it as thoroughly as possible to add clarity.

  • If you’re attending Voice of Blockchain from August 24-25 in Chicago be sure to catch Marco Peereboom and Alex Yocom-Piatt, they will be participating in panels on governance, scaling, and decentralized exchanges.

  • Early experiments with torrent-style CDN acceleration of p2p live video content have shown promising results, but we're developing a real world testbench to quantify how much broadcasters can save off their CDN bills using Livepeer's network to orchestrate P2P delivery. 

Ryan from FOAM

  • As we continue main-net launch preparations and Rinkeby testing for the end of August we have also started on a mobile track for the FOAM Map. While the map will not be optimized for mobile on day 1 we are excited to share that our application already works our of the box with Coinbase Wallet and Status, preview here.

  • Uber Visualization Newsletter featured our work, writing: "Ever wonder if blockchain could be applied to democratize maps? FOAM is leading the way and recently published the Spatial Index, a general purpose blockchain visual explorer. See how they are utilizing Uber deck.gl to visualize an interactive map of network activity utilizing the FOAM protocol here."

David from Sia

  • Nebulous repo was updated. 2 issues were created, 1 was closed. 2 PRs were merged 

  • GitLab users tbenz9 and MSevey, and GitHub user lukechampine, had code contributions merged into Sia.

  • The external contributor tbenz9 corrected the permalinks format on the documentation, that stopped working after the migration to GitLab (https://gitlab.com/NebulousLabs/Sia/merge_requests/3197).

  • MSevey corrected a bug where files with blank names could be uploaded, what was problematic for handling. Now Sia returns an error if the user tries to upload a file with a blank name this instead (https://gitlab.com/NebulousLabs/Sia/merge_requests/3188).

  • After the migration to GitLab, the import paths from the GitHub repository were left not working. Lukechampine has corrected the last changes, so the paths are working again (https://github.com/NebulousLabs/Sia/pull/3189). Also, the old GitHub repository has been archived and the readme.md file has been replaced to refer to the link of the new GitLab repo instead (https://github.com/NebulousLabs/Sia/pull/3188).
