Zcash

P2P Protocol

"Encrypted electronic cash" — the first cryptocurrency to implement zero-knowledge proofs (zk-SNARKs, via the Zerocash protocol) for optional fully-shielded, privacy-preserving transactions, built on a Bitcoin-derived codebase. Governance is genuinely multi-stakeholder: Electric Coin Company (the original for-profit developer), the Zcash Foundation (non-profit), and Zcash Community Grants (a community-elected funding body) all play distinct roles, trending toward more community control since 2020.

Detalhes

Licença MIT — confirmed via the repo's COPYING file. One narrow exception worth noting: the bundled Oracle Berkeley DB 6.2.x dependency is separately AGPL-licensed.
Status de Dev 🟢 Ativo
Proprietário Electric Coin Company (original developer, for-profit) — but not the sole steward; see Governing Body.
Órgão de Governança Multi-stakeholder — Electric Coin Company (core dev), Zcash Foundation (non-profit, ecosystem/protocol stewardship), Zcash Community Grants (community-elected dev-fund allocation body). No single entity holds unilateral authority.
País N/A (multiple entities across jurisdictions)
Ano de Início 2016
Stack C++ (zcash/zcash, Bitcoin-derived codebase).
Financiamento Multi-source — Electric Coin Company's own revenue/investment, Zcash Foundation grants, and the on-chain "dev fund" allocated in part via Zcash Community Grants' community-elected process.

P2P Protocol Atributos

Origins "Encrypted electronic cash," Bitcoin-codebase fork adding the Zerocash protocol's zk-SNARK-based shielded transactions (optional, not default — a key contrast with Monero's default-private model).
Database N/A
Query Language N/A
Data Formats Bitcoin-derived binary block/transaction format, extended for shielded-transaction data.
Collaborative Live Editing N/A
Rich Text Editing N/A
Mobile Support Via third-party wallets (Zashi — the official ECC-developed wallet; Ywallet, etc.).
Web Support N/A directly; wallet ecosystem provides access.
Native Apps zcashd/zebra — two independent node implementations; Zebra is a from-scratch Rust rewrite maintained by ECC, a genuine second independent implementation.
Terms Free, open-source (MIT, confirmed; note the bundled Berkeley DB 6.2.x dependency is separately AGPL-licensed); network fees paid to miners, with a dev-fund percentage routed to the ecosystem.
Funds Dev fund is disclosed at a protocol level (a defined percentage of block rewards); allocation via Zcash Community Grants' community-elected process.
Based On Forked from Bitcoin Core's codebase, adding the Zerocash zk-SNARK protocol.
P2P Architecture Bitcoin-derived gossip network of full nodes; PoW-based (current as of this research pass).
Overlay Network Global, permissionless.
Content Addressing No.
Local-First N/A
E2EE Shielded transactions (zk-SNARKs) are the closest analog to E2EE in this matrix's vocabulary — genuinely optional/opt-in per-transaction, unlike Monero's default-on model. This privacy-by-default vs. privacy-optional distinction is the same affordance-vocabulary gap folded into Story 9.42.
CRDTs Lib N/A
Byzantine Fault Tolerance Nakamoto-consensus-equivalent (PoW longest-chain).
Signature ECDSA (secp256k1) for transparent transactions; zk-SNARK proofs (not a signature scheme) authorize shielded transactions.
Permissions Permissionless.
Semantic Web Compatibility No.
Smart Contract No.
Protocol Stack Position Base-layer settlement (Layer 1).
Asset / Value Embedding Native (ZEC) only.
Protocol Maturity / Standardization Mature, mainnet since 2016, no formal external standards body; Zebra's emergence as an independent second client is a meaningful maturity/decentralization signal.
