Proof of Work #72
A few housekeeping notes; We’re now running updates from Keep & Solana, two interesting new projects. As I’ve noted before, we run updates from a variety of projects with the only criteria being that they are doing something interesting technologically or socially in the space—I’m not an investor in either Keep or Solana, but am personally interested in reading their updates and seeing how they progress.
A neat thing someone built recently: PoolTogether, a lottery based on the prize-linked savings account mechanic, where each user locks up some money, and then one user is awarded all of the interest accrued on everyone else’s deposits (which are lent out on PoW’s own compound.finance, but the principal is returned to each depositor. Interested to see if anyone forks this to a rake-free version (PoolTogether takes 10%), since doing so would be trivial. In the case where PoolTogether spent all of their 10% rake doing marketing, I’d expect that to outcompete a totally rake-free version that no one would have any incentive to market.
Especially interesting updates from Sia, Grin, and the Plasma group this week. More next week!

David from Sia
Sia is a decentralized cloud storage platform leveraging blockchain technology to create a data storage marketplace that is more robust and more affordable than traditional cloud storage providers.
RC2 version of the upcoming 1.4.1 version of Sia was released in Discord for testing. It features memory use, performance and UI improvements compared to the previous RC.
Eddie, Zach, Manasi, and Steve worked on multiple improvements on the UI, as more clear explanation texts, improved screens when creating an allowance or recovering backups, the ability to cancel the allowance on the UI and the correction of multiple visual glitches.
Matt added a new API endpoint for checking the current filter of hosts set up by the user: /hostdb/filtermode [GET]. On siac, this is used with the command siac hostdb filtermode. The previous command for setting a new filter has been moved to siac hostdb setfiltermode.
David tweaked the Hosts selection process when the renter forms an allowance, that now penalizes harder hosts with little remaining storage if the software expects it won’t suffice for our storage needs.
The Sia network reached 400 TB of used storage. This represents a 100 TB increase in the last 25 days
The Goobox app developers published an article explaining how to backup Synology NAS machines on the Sia network using their SiaS3 product: https://medium.com/@goobox/backup-files-to-sia-using-synology-nas-goobox-2f31e273bbab
