Company profile
researched Aug 2026Polyhedra Network develops zero-knowledge proof (ZKP) technology and blockchain infrastructure. Its product portfolio comprises Ocash, a programmable, privacy-preserving settlement layer described as private by default and compliant when needed; zkBridge, a cross-chain messaging and bridging system; Proof Cloud, a proving service; and Expander, a proving system implementation. EXPchain is the company's blockchain designed for AI applications, supported by developer resources including documentation, a GitHub repository, a block explorer, a faucet, a bridge and a marketplace.
EXPchain is positioned as a foundation layer for AI applications and is organized around three stated outputs: verifiability (proving that large language models behave responsibly), data security (protecting user data), and performance (speed and scalability for large-scale adoption). The company cites projections that the global AI market will contribute up to $15.7 trillion to the economy by 2030 as context for this focus.
ZKJ is the network's token, used for gas, liquidity, community and governance, with associated tokenomics, staking and governance functions surfaced on the company's site.
Latest developments
The Ocash retail mainnet alpha is live, and ZKJ staking is promoted alongside tokenomics and governance functions on the company's site.

Market position
Polyhedra frames itself as a research-driven organization whose products derive from its own zero-knowledge proof work, and highlights ecosystem indicators such as total messages processed, supported blockchains, ecosystem partners, algorithms, papers, citations and backers.
Technology
Polyhedra's technology stack is built on zero-knowledge proof research, with several named proof systems described on its site. MissileProof is a succinct range proof for vectors with constant proof size and verification time, built on a sumcheck and zerocheck for bivariate polynomials and yielding proofs under 1KB, applicable to anonymous payments and asset auditing. Virgo is a zero-knowledge argument scheme for layered arithmetic circuits without trusted setup, based on Libra, reported to generate a proof for a Merkle-tree circuit with 256 leaves in 53 seconds. Virgo++ generalizes the GKR interactive proof protocol from layered to arbitrary circuits while retaining prover complexity linear in circuit size, generating proofs for circuits of more than a million gates in under a second, reported as 13 times faster than the original protocol on the corresponding layered circuit. Orion reduces proof generation time with practical proof size and verification, targeted at off-chain applications and zkEVMs. Libra is a high-performance proof system implemented and optimized in the company's core codebase. Gemini is a hardware-friendly proof system with multiple time/memory configurations, including a space-efficient mode using logarithmic memory. Marlin provides constant-size proofs verifiable in milliseconds using holography, reducing proof size and on-chain verification cost. Pianist applies distributed computing to combine many machines into a single proof generation system for horizontal scalability, and has been combined with Libra. The company also publishes technical papers on zkPyTorch and zkBridge.
