According to CoinMeta, the security startup Attestable completed a $20 million seed round of financing, led by Jamin Ball from Altimeter Capital and Yonatan Mandelbaum from TLV Partners. Attestable uses zero-knowledge proof technology to build a universal verification layer that enables verification and inference of a 30B model on NVIDIA H100 GPU at a speed of 85 token per second. Ethereum co-founder Vitalik Buterin stated that the performance overhead of zero-knowledge proofs for large language models has now approached single-digit levels.
