ChainCatcher news, the Telos Foundation announced on the X platform the launch of the proof aggregator Plonky2 Goldibear, which is its latest advancement in cryptographic proof generation and aggregation, aimed at providing performance improvements, especially in recursive proof combinations in the BabyBear domain.It is reported that Plonky2 Goldibear is the latest iterative version of the Plonky2 prover, supporting proof generation in both the Goldilocks domain and the BabyBear domain.

ChainCatcher news, according to the official Twitter, Ola has recently supported Poseidon2 hash in its proof system. Compared to the original Poseidon hash, it has achieved a 40%+ performance improvement for provers.It is reported that Poseidon2 is a new hash algorithm that maintains the same level of security as Poseidon hash while having better zk-friendly characteristics. Since zk-friendly hash algorithms are widely used in Ola's proof system, including private state tree, public state tree, verification process, plonky2 recursive process, etc., after in-depth research on the algorithm and implementation of Poseidon2 hash in the Horizen Labs paper, Ola has officially integrated it into the proof system.According to official sources, the Ola ZKVM testnet will be launched in early Q4 of this year, and more development details will be announced soon.

ChainCatcher news, according to CoinDesk, Matter Labs denied the allegations from Polygon Zero, stating that the code "clearly indicates the source" in a line at the top of one of the files. A Matter Labs spokesperson stated that Polygon's article contains "false claims," and that "the new Boojum high-performance proof system utilizes 5% of Plonky2, which is clearly indicated in the first line of our module."In a screenshot of a Matter Labs file named "mod.rs," Polygon stated that the file "does not credit the original author." Matter Labs CEO Alex Gluchowski stated that the first line of the mod.rs file clearly indicates, "Note: We use the non-vectorized field implementation of Plonky2 as a baseline." However, Matter Labs has not yet responded to other cases mentioned by Polygon Zero.

ChainCatcher news, the Polygon official zero-knowledge proof team Polygon Zero stated that the recently released Boojum proof system by Matter Labs contains a large amount of source code copied and pasted from the performance-critical components of the Plonky2 library, without attribution to the original copyright or authors. Besides the directly copied code, Boojum is extremely similar to Plonky2. It uses the same parallel repetition strategy to enhance robustness in small ranges, employs similar custom gates for efficient recursive verification arithmetic, and utilizes the same lookup parameters developed by Polygon Zero member Ulrich Haböck.In addition, Polygon Zero also stated that the founder of Matter Labs claims that Boojum is over 10 times faster than Plonky2, which is a misleading statement.
