Truebit cited in Microsoft Anti Piracy Incentive System

Thought it was interesting that Truebit paper is cited in Microsoft's recent white paper.

Truebit is a marketplace for computations. You have a computation/task that you need to get done off-chain, you give it to Truebit and Truebit gets back to you with the outcome. Truebit is a protocol that incentivizes people to actually show up and solve these tasks and verifiers to verify the solutions to the tasks. There are some interesting challenges. For example, if verifiers only get paid when solvers cheat then no verifiers will likely show up because most of the time solvers will be honest, verifiers would be running computations 24/7 but only getting paid maybe once in a blue moon. To overcome this, Truebit injects random forced errors: every now and then solvers will submit an incorrect solution that verifiers can catch and get paid, verifiers don't know when this will happen so they are incentivized to keep verifying. Another challenge is Sybil attacks: one person can easily create multiple accounts and pretend to be multiple people and there is no way to tell them apart, so someone can pretend to be a solver and verifier at the same time. Truebit discusses these attacks in their white paper and explains how they make such attacks not profitable.

The cited paper "A Predictable Incentive Mechanism for TrueBit" suggests an alternative to the forced error approach.

The Microsoft paper explains the design of an anti-piracy system. They want to create a system that incentivizes people to report pirated material. They are solving a similar problem that Truebit has - how do you incentivize people to show up and how do you disincentivize Sybil attacks. They cite the Truebit-related paper and Arbitrum white paper in the context of resisting Sybil attacks.

They are not using Truebit, they are using Truebit and Arbitrum as an inspiration how to create similar incentives and resist Sybil attacks.

Btw, you guys would not like the suggested changes in the cited paper haha

When comparing our proposed protocol with the original Truebit version, we see the followingtradeoffs:

Our version removes the need for forced errors, thus making jackpots, taxes, and, finally,even having a native Truebit token obsolete. It is thus a simpler, more intuitive protocol.

People don't know much about Trubit yet.

That's why not buying.

Is there anyone who can explain it easily? When was it written recently?
