Shielded Zcash address that keeps sender, receiver, and amount private using zk-SNARKs, contrasted with t-addresses that are transparent like Bitcoin.

Stacking order property that controls which element appears on top in layered UIs, relevant for modals, wallet prompts, and canvas overlays in dapps.

Space-filling curve used to map multidimensional data to one dimension while preserving locality. Applied in databases, graphics, and some Merkleized indexes.

Number of standard deviations a value is from the mean; useful for anomaly detection in exchange flows, validator metrics, and AI feature engineering.

Format for storing large N-dimensional arrays in chunks across filesystems or object storage; handy for ML datasets and on-chain analytics features at scale.

Privacy-focused blockchain that introduced zk-SNARKs to enable shielded transactions. Supports transparent and shielded pools; proposals tracked as ZIPs.

Special Ethereum address of all zeros used as a burn sink, default value, or sentinel in smart contracts. Transfers to it are effectively unrecoverable.

Transaction whose gas is sponsored by a relayer or paymaster, enabling users to sign but not fund fees directly. Common with smart accounts and onboarding flows.

Security model that assumes no implicit trust based on network location. Enforces continuous verification and least privilege for users, services, and machines.

Cryptographic method to prove a statement is true without revealing the underlying information. Powers private payments, identity, and L2 rollups.

A cryptographic method to prove a statement is true without revealing the underlying information.

High-performance messaging library with pub/sub, req/rep, and pipeline patterns. Used in node infrastructure, indexers, and trading systems for low-latency IO.

Low-level systems language focused on performance and safety without a GC; used for crypto tooling, provers, and high-assurance infrastructure components.

Low-power wireless mesh networking standard used in IoT. Relevant to oracle hardware, sensor networks, and trusted data collection at the edge.

Sharded smart-contract platform with Scilla language and token standards like ZRC-2; designed for high throughput and parallel transaction processing.

Governance and specification documents for protocol changes in Zcash, analogous to Ethereum’s EIPs and Bitcoin’s BIPs. Numbered and versioned proposals.

Cross-chain bridge that verifies state using zero-knowledge proofs instead of multisigs or external validators, reducing trust assumptions for asset transfers.

An EVM-compatible environment where execution can be proven with zero-knowledge proofs. Comes in types (1–4) balancing bytecode equivalence, prover speed, and compatibility.

L2 scaling that posts compressed state and validity proofs to L1. Offers strong security with fast finality once the proof is verified on-chain.

Succinct Non-Interactive Argument of Knowledge enabling short proofs and fast verification. Common schemes include Groth16 and PLONK; often needs a trusted setup.

Scalable Transparent Argument of Knowledge that avoids trusted setup and uses hash-based security; proofs are larger but post-quantum friendly assumptions are appealing.

Virtual machine whose execution trace can be proven in zero-knowledge, often RISC-V or custom IR based, enabling general-purpose verifiable compute.

Hash primitives designed for efficient use inside ZK circuits, e.g., Poseidon or Rescue, minimizing arithmetic constraints for Merkle trees and commitments.

File format used by tools like snarkjs containing proving and verification material derived from a trusted setup ceremony for zk-SNARK circuits. Handle with care.

Techniques to prove ML model inference was executed correctly without revealing model weights or inputs, enabling private scoring and verifiable on-chain AI.

Runtime validation and TypeScript-first schema library used to enforce API and config shapes in dapp frontends, bots, and serverless functions.

Distributed coordination service for configuration, naming, and leader election. Underpins many Kafka and HBase deployments in analytics for on-chain data.

Fungible token standard on Zilliqa akin to ERC-20; defines interfaces for transfers, allowances, and metadata on the Scilla smart-contract platform.

Unix shell with advanced completion and scripting features, widely used by developers. Pairs with tools like Oh My Zsh for productivity on blockchain ops boxes.

Modern compression algorithm with high ratios and fast speeds; widely used for log archives, snapshots, and state sync in blockchain and ML data pipelines.
