PoCo #4 — What is PoCo and why is it needed?

PoCo Series #04

The PoCo series of articles discusses the Proof-of-Contribution protocol developed by iExec.

The first episode of this series gave an outline of the protocol. In the second episode, we had a deeper look at the consensus mechanism, where we discussed the use stake and the (non-) effectiveness of different attack scenarios. In this third episode, we will describe an updated, more detailed, version of the protocol along with all transactions involved in achieving consensus.
