> You can hold DAI without opening a CDP If you hold Dai without opening a CDP, the only way to convert that Dai back to Eth is to find someone who opened a CDP and is willing to buy from you. Similarly, if you opened a CDP and then sold

A good fix requires the whole system to be re-imagined a bit. You want to start with the invariant that a stablecoin holder can liquidate to Eth at any point, and that a collateral issuer can extract their Eth at any point. Instead of havin

A lot of Ethereum DeFi (and cryptocurrency in general) has been pretty frustrating to watch, because it's a lot of people with big ideas and little understanding of how to build stable financial systems. In the case of Maker, what&#x27

The target audience is people who are concerned that Sia's long term economic story is fragile, and can't survive beyond what underutilized storage exists today. The types of farms described in the article are what I imagine Sia t

Sia is a lot more than a low cost storage platform. It's a full reimagining of how the cloud should work with an emphasis on user ownership and control, open access for developers, and ultimately decentralization that allows users to b

Definitely not, aggregate uptime is extremely high. We've never seen downtime do to network outages, only software bugs. And even then, only some users were impacted by the bugs, we've never in 5 years had a broad outage.

Sure! First up, we don't do repairs every time one host goes down. Standard practice on the network is to wait to do a repair until a full 25% of the redundancy is missing (in 64-of-96, that would be 8 hosts offline). Then you repair a

CPU TDP is accounted for, the CPU linked in the blog post draws 65w and that is used in the electricity calculations. I did realize that I completely forgot about RAM, when I get back to a computer I'll have to make some updates, but i

Sia, the system described above, comfortably handles files of 100-200 gb, and with the recent Skynet link also enables filesharing for files up to 400 GB.

Each of the 64 pieces is fetched from a different host on the network, meaning all of the IOPS are happening in parallel at network speeds. You aren't going to be doing sub-millisecond updates for sure, but you can easily get under 100

Its super interesting to dive into the world of cryptocurrency mining, where some DCs are getting PUE of 1.1 or better with a buildout that's basically amounts to shelves and box fans. No generators, just eat the downtime. No batteries

It's similar to optimization in that it follows a U-curve. Up to a point, simpler things have more performance, and simpler things have less downtime. But after a certain point, it's no longer enough to make it simpler. You have t

Skynet is barely two weeks old fwiw. As more people play around with it and see how strong it is I think it'll get a lot more attention. Lot of crypto projects are already planning to add support in the coming months.
