Our ZK Innovations
Virgo
Virgo presents a powerful zero-knowledge argument scheme for layered arithmetic circuits without trusted setup based on Libra. It enjoys a fast prover as well as competitive proof size and fast verification time. Experiments show that it only takes 53 seconds to generate a proof for a circuit computing a Merkle tree with 256 leaves, at least an order of magnitude faster than all other succinct zero-knowledge argument schemes.
Virgo ++
Virgo++ generalizes the interactive proof of GKR protocol for layered circuits to arbitrary circuits, while preserving the optimal prover complexity that is strictly linear to the size of the circuits. Not only does our new protocol achieve optimal prover complexity asymptotically, but it is also efficient in practice. Our experiments show that it only takes less than one second to generate the proof for a circuit with more than a million gates, which is 13 times faster than the original interactive proof protocol on the corresponding layered circuit.
Orion
Orion is the latest proof system that utilizes the most recent advancements in the area. The system significantly reduces the proof generation time with practical proof size and verification time. The system is best suited for off-chain applications and zkEVMs.
Libra
Libra is a high performance proof system that achieves high speed by directly making an algorithm breakthrough without doing any trade-off. The system has been implemented, modified and optimized in our company’s core codebase. Our experiments show that the new implementation beats other proof systems by an order of magnitude.
Gemini
Gemini, a hardware-friendly zero-knowledge proof system, will help Polyhedra accelerate proof generation by leveraging specialized hardware. The Gemini prover has multiple configurations with different time and memory tradeoffs, which can be selected depending on the execution environment and the proved statement. The output proof is independent of the chosen configuration. In a space-efficient configuration, the Gemini prover uses a logarithmic amount of memory, enabling super-fast hardware with limited memory.
Marlin
Marlin, a zero-knowledge proof system with constant verifications, will help Polyhedra reduce the proof size and on-chain verification costs. Marlin exploits a novel use of holography, where fast verification is achieved provided the statement being checked is given in encoded form. The result arguments have constant size and can be verified within several milliseconds.
