ZK Coin Zero-Knowledge Proof's Invisible Cloak Token
ZK Coin (ZK) is the native token of the zkSync network, which is one of the most advanced Layer 2 scaling solutions on Ethereum, officially launching ZK in June 2024. In simple terms, zkSync is like giving Ethereum an invisible cloak: transactions are fast and cheap, and extremely secure, while ZK Coin is the ticket and vote for this highway.
zkSync uses zk-Rollup technology, with the core being Zero-Knowledge Proof, which bundles thousands of transactions off-chain and mathematically proves that these transactions are valid, then submits only a very small proof to the Ethereum mainnet. This ensures security (no one can act maliciously) and allows speeds of thousands of transactions per second, with gas fees as low as a few cents, making it safer than Optimistic Rollup (Arbitrum, Optimism) since it does not require a 7-day challenge period.
The main uses of ZK Coin are threefold:
1. Paying network gas fees (though ETH can also be used, ZK is cheaper).
2. Governance voting: holding ZK allows for decisions on network upgrades, fund allocation, and other major issues.
3. Ecosystem incentives: distributing ZK to users and developers through airdrops, grants, and developer rewards.
The total supply of zkSync is 21 billion coins, and during the major airdrop in 2024, many early users and developers directly received several hundred to several thousand dollars worth of ZK, making it one of the most sought-after airdrops that year. The price peaked around $0.4, and now it generally fluctuates between $0.15 and $0.25.
By 2025, zkSync's TVL (Total Value Locked) has exceeded $10 billion, with popular projects like SyncSwap, ZeroLend, and ZKSpace emerging in the ecosystem. It also launched the Elastic Chain, allowing developers to easily build their own subchains, and is expected to become the king of Layer 2 in the future.
ZK Coin is one of the most hardcore tokens in the zero-knowledge proof sector. If you believe zk-Rollup is the ultimate direction for Ethereum scaling, zkSync is the leader in this direction, and ZK is a foundational infrastructure coin worth holding long-term.
