Electric Coin Company (then the Zerocoin Electric Coin Company), led by Zooko Wilcox, built and shipped it. Sprout introduced the first practical zk-SNARK shielded transactions and the original shielded pool, so people could send ZEC with the sender, receiver, and amount hidden while the network still checked that the balances added up. The name signaled a young, budding chain that the team expected to grow.
Why this matters. Every public blockchain before Sprout put your payments on display: anyone could see who paid whom and how much. Sprout was the first live, permissionless network to hide those details and still prove no one was cheating. That matters for ordinary financial privacy, the kind you expect from cash or a bank statement no one else can read. It also proved that strong on-chain privacy could work in practice, beyond a paper design. The trusted-setup Ceremony that made it possible became a reference point for later cryptography work, and the slow, memory-heavy proving system Sprout shipped with is exactly what pushed the team to build Sapling two years later.

The zk-SNARKs in Sprout needed a set of public parameters, and generating them safely required a one-time setup called the Ceremony. Six participants in separate, distant locations each generated a secret piece, called toxic waste. If anyone ever reassembled all the pieces, they could forge ZEC out of nothing. The design turned that risk into a simple rule: as long as at least one participant destroyed their piece, the full secret could never be rebuilt, so counterfeiting stayed impossible. The participants who have been named publicly include Zooko Wilcox, Andrew Miller, Peter Van Valkenburgh, Peter Todd, and Derek Hinch of NCC Group. One participant chose to stay anonymous.

Sprout is the baseline that every later change builds on. When the network-upgrade mechanism arrived with Overwinter, it labeled the original rules as consensus branch id 0, which simply means no upgrade has been applied yet. Everything since then (Overwinter, Sapling, Blossom, Heartwood, Canopy, NU5, NU6, and onward) sits on the chain Sprout started. The launch was announced in August 2016 for an October 28 genesis, the Ceremony ran in the weeks before, and the genesis block's hardcoded timestamp reads October 28, 2016, at 07:56 UTC.

Why is there no ZIP number for Sprout? The ZIP process began later, with the Overwinter upgrade. Sprout is the original launch, described by the Zcash Protocol Specification and the Zerocash construction it was based on. ZIP 200 only mentions Sprout in hindsight, as consensus branch id 0, the baseline before any upgrade.

What made Sprout different from Bitcoin? Bitcoin puts every payment on a public ledger where amounts and addresses are visible. Sprout added shielded transactions that hide the sender, receiver, and amount while still letting the network confirm the transaction is valid. It kept transparent addresses too, so both styles live on the same chain.
