It's quite rare that @ RiscZero voluntarily closed the official custody proof service Bonsai and embraced @ boundless_xyz's decentralized proof market service. This indeed means that the ZK general proof market has entered a new stage of decentralization. So, why is it said to be rare? 1) An objective fact is that most layer 2 providers, regardless of the OP/ZK camp, provide executive layer services and are generally officially hosted during the cold start phase. For example, the Sequencer of Arbitrarum, the prover of zkSync, the proof node of Starknet, and so on; This is not a technical issue, but a market-oriented preference choice, because official custody services are a "cash cow" with pricing power, strong customer stickiness, high profit margins, and the key is that they do not have to bear the uncertainty risk of decentralized networks. Therefore, they were originally just transitional solutions, and walking became the "end result"; 2) So, RISC Zero took the initiative to move its official hosting services to the decentralized market, which is actually a bit of "heroic courage". This is not as simple as everyone expected, just shutting down the server. Behind it, there needs to be a mature technical service framework to support it, such as an incentive mechanism to attract Prover and avoid idling; The pricing mechanism should meet the dynamic balance of supply and demand; The dispute arbitration mechanism should be sufficient to handle quality disputes and so on. In short, switching to a decentralized market indicates two things: 1. The maturity of Boundless's Prover network is high enough to fully hand over service quality to the free market; 2. RISC Zero has truly implemented decentralization, unlike most projects that are just slogans. The above. Although there has been less attention paid to this type of technology topic in the market, the trend towards a decentralized Prover market is becoming mature, which is definitely a great benefit for a group of layer 2 or other public chains based on ZK Coprocessor that focus on ZK Rollup. At least there is an option for outsourcing to access decentralized solutions. @sshankar Great Move!
