Zero-Knowledge Proof

The key difference between Manta Pacific and Manta Atlantic lies in their functional roles: Pacific is a modular Layer 2 network on Ethereum, specializing in zero-knowledge (ZK) decentralized application deployment and scaling; Atlantic is a ZK Layer 1 network on Polkadot, dedicated to zkAddress and zkSBT on-chain compliance identity infrastructure. Both chains are part of the Manta Network ecosystem and share the MANTA native utility token, but they exhibit structural differences in their underlying ecosystems, technical stacks, and target user groups.

Manta Network (MANTA) is a modular blockchain ecosystem designed for zero-knowledge (ZK) applications, consisting of Manta Pacific—a modular Layer 2 network within the Ethereum ecosystem—and Manta Atlantic, a ZK Layer 1 network on Polkadot. Pacific utilizes the Celestia data availability layer alongside the EVM/zkEVM execution environment to support decentralized applications, while Atlantic specializes in on-chain compliant identity, delivering programmable zero-knowledge identity infrastructure via zkSBT and zkAddress.

Universal Circuits is a ZK-as-a-Service pre-built circuit library deployed on Manta Pacific: Solidity developers can add zero-knowledge functionality to their dApps via standard contract interfaces, without needing to switch to specialized ZK languages like Cairo; typical applications include compliant payments, identity verification, and on-chain games such as zkShuffle.

zkAddress and zkSBT are core privacy identity components developed by Manta Network on the Manta Atlantic chain. zkAddress offers reusable UTXO-style privacy addresses, while zkSBT binds compliance credentials to that address using zero-knowledge proofs. Together, they form the compliant identity infrastructure on the Atlantic chain, enabling Web3 applications to verify identities without revealing users’ original personal data.

Bridging assets to Manta Pacific involves a repeatable process of locking, minting, and mapping balances between Ethereum mainnet and Manta Pacific, a modular Layer 2 network, via a cross-chain bridge. As the execution layer of Manta Network within the Ethereum ecosystem, Manta Pacific enables on-chain deployment and interaction for ETH, ERC-20, and other assets. To participate in ecosystem applications on the Pacific side, users must first understand how the bridge is triggered, how system states change internally, and how to confirm that funds have arrived.

Zcash Orchard is the third generation shielded pool in the Zcash network. Built on the Halo 2 zero knowledge proof system, it is designed to improve the efficiency, scalability, and long term upgradeability of private transactions. Compared with the earlier Sprout and Sapling pools, Orchard reduces reliance on trusted setup and optimizes the proof generation and verification process.

Nockchain works by replacing traditional PoW hash calculations with Zero-Knowledge Proof generation. In Nockchain, miners no longer compete for blocks through meaningless hash operations. Instead, they participate in network consensus by generating verifiable proofs. Nockchain’s architecture includes components such as NockVM, NockApp, Proofpower, and Global Consensus SNARKs, aiming to build a decentralized proving network that supports AI, privacy applications, and Verifiable Computation.

Nockchain is a blockchain network based on Zero-Knowledge Proof-of-Work, or ZKPoW. Its core goal is to replace the meaningless hash calculations used in traditional PoW with verifiable zero-knowledge proof generation, also known as ZK proving, that has real practical value. Unlike Bitcoin, which relies on competition over computing power, Nockchain uses miners’ computational resources to generate verifiable computation proofs, creating a “Useful Proof of Work” model.

Railgun and Tornado Cash are both on-chain privacy protocols, but their design goals and operating models are clearly different. Tornado Cash is closer to an anonymous mixer, using fixed-denomination pools to break links between funds. Railgun, by contrast, is a zk-SNARK-based Private DeFi protocol that supports privacy accounts, private transactions, and anonymous smart contract interactions.

Railgun is a privacy DeFi protocol built on EVM blockchains. It uses zk-SNARK zero-knowledge proof technology to hide user addresses, asset balances, transaction amounts, and on-chain behavior, while preserving composability with ecosystem protocols on Ethereum, Arbitrum, BNB Chain, and other networks. Unlike traditional privacy coins or mixers, Railgun does not rely on a separate blockchain. Instead, it enables private transactions and anonymous smart contract interactions directly on native chains.

SP1 zkVM is a general purpose zero knowledge virtual machine that allows developers to write arbitrary programs in Rust and generate verifiable ZK proofs. It is suitable for cross chain systems, Rollup scaling, and verifiable AI computation. zkEVM, by contrast, focuses on proof generation compatible with the Ethereum ecosystem, mainly for on-chain transaction and smart contract verification. The two differ significantly in programmability, verification efficiency, decentralized computing power, and ecosystem integration, so developers can choose the most suitable ZK infrastructure based on their application needs.

SP1 zkVM is a general purpose zero knowledge virtual machine, or zkVM, launched by Succinct. It allows developers to write programs in Rust and automatically generate ZK proofs. Its core process includes compiling Rust programs into RISC-V instructions, executing them in the zkVM to generate an execution trace, converting the trace into a STARK proof, compressing it into a SNARK proof, and finally submitting it for on-chain verification.

Succinct’s Prover Network is a decentralized computing power market for zero knowledge proofs, or ZK proofs. It connects proof requesters with Prover nodes around the world. Developers initiate a proof request by submitting program code and input data. The network’s Auctioneer then assigns tasks based on cost, speed, and node reputation. Prover nodes execute the program on SP1 zkVM and generate the ZK proof, which is ultimately submitted on-chain for verification and settlement.

Succinct is a decentralized zero knowledge proof, or ZK proof, network built on Ethereum. It is designed to give developers programmable, low barrier infrastructure for proof generation. Through its core component, SP1 zkVM, developers can write verifiable programs directly in general purpose programming languages such as Rust, without manually designing complex ZK circuits. The Succinct Prover Network connects proof requests with global computing resources through an open Prover market, enabling proof generation, verification, and settlement.

Succinct and RISC Zero both provide zero knowledge proof, or ZK proof, infrastructure, but they are designed with different goals in mind. Succinct places greater emphasis on a decentralized proof market and a general purpose verification layer. Through its SP1 zkVM and Prover Network, it supports cross chain verification, Rollups, and verifiable AI computation. RISC Zero, by contrast, focuses more on a verifiable execution environment and developer experience, using RISC-V architecture to lower the barrier to building ZK applications. The two differ significantly in zkVM architecture, proof generation flow, economic mechanisms, ecosystem positioning, and suitable use cases.
