## 1. What is Zcash ($ZEC) and Who Created It?
Zcash was officially launched on October 28, 2016. It was co-founded by Zooko Wilcox-O'Hearn in collaboration with the Electric Coin Company (ECC) and top academic researchers.
The primary goal of Zcash was to address Bitcoin’s lack of true transactional privacy. While Bitcoin transactions are publicly visible on an open ledger, Zcash provides users with an optional layer of complete financial confidentiality.

## 2. All-Time High (ATH) & Market History
Zcash has one of the most unique launch price histories in the entire crypto industry:
* **All-Time High (ATH):** $5,941.80 USD (recorded across key market trackers like CoinGecko and exchange metrics).
* Why Was the ATH So High? When Zcash launched in October 2016, market anticipation was extremely high, while initial circulating supply was close to zero. This extreme supply scarcity combined with massive speculative demand drove its price to parabolic heights during its first week of trading.
* Bull Cycle Valuation: In subsequent broad market bull runs (such as 2017–2018), ZEC traded at sustained high peaks between $750 and $950 USD.

## 3. How Does Zcash Work? (zk-SNARKs Technology)
Zcash’s core technological foundation rests on zk-SNARKs (*Zero-Knowledge Succinct Non-Interactive Argument of Knowledge*).
### What are zk-SNARKs?
zk-SNARKs are a form of Zero-Knowledge Proof cryptography. It allows one party to mathematically prove to another that a statement is true (e.g., "I have sufficient funds for this transfer") without revealing any underlying data (such as account balances or identity).
* Bitcoin Model: Everyone can publicly see: "Address A sent 2 BTC to Address B."
* Zcash (Shielded) Model: The network mathematically verifies that a valid transaction took place without revealing the sender, receiver, or exact transaction amount to the public.

## 4. Transparent vs. Shielded Addresses
Zcash offers flexible privacy settings through two distinct types of wallet addresses:
1. Transparent Addresses (t-addresses):
* Work similarly to Bitcoin.
* Transaction amounts and addresses are publicly visible on the Zcash block explorer.
* Widely used by centralized exchanges for compliance and auditing.
2. Shielded Addresses (z-addresses):
* Fully encrypted using zero-knowledge proofs.
* Keeps sender details, receiver details, and transaction amounts completely private.
Users can seamlessly transfer funds between t-addresses and z-addresses depending on their specific privacy needs.

## 5. Tokenomics & Key Specs
* Maximum Supply: 21 Million ZEC (Hard-capped, identical to Bitcoin’s total supply cap).
* Consensus Mechanism: Proof-of-Work (PoW) using the Equihash algorithm.
* Block Time: Approximately 75 seconds per block.
* Halving Schedule: Follows a 4-year halving cycle that cuts block rewards in half over time to control inflation $ZEC
