DAI is not algorithmic at all, but it is controlled by smart contracts. For $1.00 of DAI to be minted, a user has to post somewhere between $1.25-$1.50 of collateral. The act of creating DAI is literally that of taking out a loan. Over time, your debt to the system accrues interest. If your collateral falls under a certain price threshold, the issuer of DAI (MakerDAO), will seize your collateral to close your position. You keep the DAI, and MakerDAO liquidating you keeps the system above water and DAI at the dollar peg.
Algostables are not collateralized at all. They're more akin to ancient gold coins. Think of Luna as a small piece of gold. When UST is created, the Luna is "melted" to form the UST. At any point, the UST can then be "melted down" to get the Luna back out of it. From a certain point of view, UST literally is Luna.
algostable != overcollateralized stable. Being an overcollateralized stable means it's actually backed by something, even if it's USDC. An algostable is backed by the sister token (eg: LUNA), and relies on faith and confidence in the sister token.
Probabilities have been calculated from Billy's footage that shows his alleged arcade games rendering as MAME. His random hammer smashes give points way higher than the mean, suggesting he stitched save states in an emulator.
I don't think there's disagreement - my score from 2016 is the one this article is about. The max is whatever the game's RNG will give you, and is probably somewhere close to 1.3m.
As top-tier play has gotten better, the ceiling has increased. We used to think this score was about as good as it was going to get, but only a few years prior, we thought the max was closer to 1.15m. Wild how things change.
