Zero Currency

Zero Currency

Zero Currency launched in 2017 as an open-source, proof-of-work blockchain that introduced the Equihash 192/7 algorithm, a memory-hard hashing design requiring at least 4GB of RAM. The project was built with no initial coin offering and no pre-mine, giving early adopters no structural advantage over later participants. Its core protocol integrates zk-SNARK zero-knowledge proofs, enabling shielded transactions where addresses, amounts, and memos remain encrypted on the public ledger while still being validated by the network. The network targets payments and privacy-sensitive transfers through two interoperable address types: transparent (t-addresses) that function like Bitcoin, and shielded (z-addresses) that hide counterparty and amount data. Blocks are produced every 120 seconds, and transaction fees fall to zero when network capacity allows. A fixed daily emission rate of 3,888 ZER, declining over time, feeds an ultimate maximum supply of 17,000,000 coins. The consensus mechanism resists ASIC domination through its memory-intensive proof-of-work, and the node layer is maintained by a community-run global infrastructure. Zero Currency does not disclose a treasury size, a core development team, or an institutional entity managing its treasury or protocol roadmap. The project operates as a community-maintained decentralized autonomous network without a known parent company, foundation, or list of named operators. No venture funding rounds, staffing headcounts, or office locations appear in the available public record. Structurally, Zero Currency differs from privacy-preserving blockchain projects such as Zcash by combining a unique Equihash parameter set with a deflationary emission schedule and an explicit zero-fee mechanism below capacity. The absence of a founder reward, development fund, or identifiable controlling entity makes it a fully grassroots protocol, though it also limits the visibility that institutional allocators typically seek when evaluating protocol-adjacent assets.
