Zcash Mining Explained: Equihash Algorithm and Rewards

How Zcash Mining Works With Equihash and ASICs Zcash mining looks simple on paper. Machines solve a puzzle, the network pays a reward, and the chain grows. In practice, hardware, power bills and the reward schedule decide who actually profits. ZEC is a proof-of-work coin built around shielded transactions, with a fixed supply of 21 million. Its miners solve a puzzle called Equihash and earn new ZEC plus transaction fees. Interest is picking up as rewards and prices both move fast. This guide explains how the algorithm works, what a block pays, what equipment you need and where the risks sit. Every core figure comes from the official Zcash website and documentation. What Is Zcash Mining and How Does It Work? Zcash mining is the work of adding new blocks to the Zcash blockchain. It uses proof of work, the same security model Bitcoin uses. Miners race to solve a hard math problem. The first one to find a valid answer publishes the block. The network checks it, adds it to the chain and pays that miner. According to the official Zcash mining guide, the problem is defined by the Equihash hashing algorithm. A new block arrives roughly every 75 seconds. That is much faster than Bitcoin's ten-minute rhythm. How Does the Equihash Algorithm Work? Equihash is a memory-hard puzzle. Memory-hard means the work depends on how fast a machine can read and write memory, not only on raw hashing speed. The goal was to keep mining open to ordinary computers. Zcash uses the 200,9 parameter set. Those two numbers set the puzzle size and memory demand. The protocol specification calls this an attempt to limit mining centralisation. The word attempt matters. The official docs now say that, at current network difficulty, you must use an ASIC to mine. An ASIC is a chip built for a single job. It beats a CPU or graphics card at that job by a wide margin. Home PCs are effectively out of the race. How Much Does a Miner Earn Per Block? The official numbers are short and clear. The official economics page lists a fixed supply of 21 million ZEC, a new block every 75 seconds and a block subsidy of 1.5625 ZEC. The subsidy is the amount of new coins created in each block.
