Ycash

Ycash (y.cash) is a cryptocurrency launched in 2019. It operates as a privacy-preserving, proof-of-work digital cash system that directly inherits the code and blockchain history of Zcash.

The protocol targets two persistent weaknesses in Bitcoin’s design: on-chain traceability and the centralization of mining power into specialized ASIC hardware. By implementing zero-knowledge succinct non-interactive arguments of knowledge (zk-SNARKs), Ycash enables shielded transactions that obscure sender, receiver, and amount. Its commitment to equitable coin distribution counters industrial mining’s chokehold on network participation.

Ycash operates on its own blockchain using proof-of-work. The network is a direct chain fork of Zcash, sharing an identical history up to block 570,000, mined on July 18, 2019. This means Zcash private keys controlling funds at that precise moment could unlock identical amounts on the Ycash chain, weaving a deeply entangled incentive structure.

The software stack fuses Bitcoin’s battle-tested transaction model with Zcash’s shielded address scheme, employing the Groth16 proving system for zk-SNARKs. Ycash’s development roadmap enforces algorithm changes—colloquially called mining algorithm tweaks—to resist ASIC dominance and keep hashing accessible to consumer GPUs and CPUs. Because the codebase stems from upstream Zcash, it inherits transparent and shielded pool interactions, memo fields, and view-key functionality without alteration.

No single founder claims prominence; the project coalesced within the Zcash community as a reaction to perceived distribution failures in the original network. The Ycash Foundation, a nonprofit entity, was established to steward protocol development and manage the Development Fund. At the fork boundary, an airdrop event occurred automatically: every Zcash holder received a 1:1 allocation of Ycash, instantly linking the two ecosystems. Early adoption coalesced around exchanges and wallets that recognized the shared key-path.

The overarching objective is blunt: to deliver uncompromising privacy alongside a mining distribution model that resists the gravitational pull of large-scale ASIC farms. Where Zcash solved the privacy problem with elegant cryptography, Ycash aims to solve the distribution problem by making mining a low-barrier, community-driven activity. This ideological strand—that a currency’s power grows when its emission reaches many hands—shapes every technical decision.

Ycash’s native coin functions as the sole unit of account for on-chain value transfer, with optional shielding that breaks public linkability. Miners are paid block subsidies and transaction fees exclusively in YEC, creating a closed incentive loop that funds network security. The protocol-level Development Fund levy—5% of post-fork issuance—is denominated in the same token, channeling resources to ongoing engineering and infrastructure without external dependencies.

Miners who run commodity hardware join the network, validate transactions, and earn newly minted coins at a rate designed to reward wide participation. Privacy-seeking users generate zero-knowledge proofs locally and broadcast shielded transactions that conceal financial footprints from public ledgers. Zcash holders who retained keys after the split can sweep their mirrored Ycash balance at any time, exercising a unique cross-chain claim that no other fork replicates.

Ycash has a maximum supply of 21,000,000 tokens. Currently, 16,669,909.38 are in circulation. From block 570,000 onward, the block reward allocates 5% of new issuance to the Ycash Development Fund, preserving the original 90% mining distribution pledge. With a market capitalization of $5,017,171, Ycash ranks #1,640 among all cryptocurrencies.
