What is Chain-key Chainlink
Canister smart contracts on ICP can integrate with the Ethereum network using a combination of replicated HTTPS outcalls to a known set of public Ethereum nodes to read state and submit transactions, and chain-key ECDSA (ckECDSA) signatures, an enhanced version of threshold ECDSA, to sign those submitted transactions.
Building upon this integration framework, ckLINK is a pair of canister smart contracts that utilize HTTPS outcalls and ckECDSA services. The ckETH minter and ckLINK ledger contracts work together to enable users and smart contracts to send and receive LINK value within seconds with negligible transaction fees, and no gas fees, while also always allowing users and smart contracts to send and receive LINK value to and from the Ethereum network.
ckLINK exposes ICRC-1 and ICRC-2 ledger interfaces (the fungible token standards of ICP), making it simple for all wallets on the Internet Computer to offer ckLINK support.
The pair of smart contracts work in unison to ensure that the total value of ckLINK is fully backed 1:1 by LINK. This can always be verified by viewing the on-chain dashboards and metrics of the canisters: ckETH Minter dashboard, ckETH Minter metrics, ckLINK Ledger metrics.
Chain-key Chainlink vs Stoic
It's almost impossible to predict which cryptocurrency will eventually emerge as the leader.
There is no guarantee that In 5 years, CKLINK would still even exist. Another faster and cheaper blockchain might capture the majority of developers, users, and capital. Or some critical failure of CKLINK might derail its progress.
Because the probability of guessing the winner is low, it's better to use a portfolio approach and buy all possible contenders, including CKLINK.
Stoic builds a portfolio by using hedge fund-grade quantitative research and AI to build a portfolio of crypto assets.
The algorithm analyzes price data, returns, volatility, correlations, and other factors to identify coins that are likely to go up. It then rebalances the portfolio daily to cut losses early and take profits regularly. Stoic is a great alternative to researching coins and trading manually.
Over 12,000 people already use Stoic to automate their crypto investing.
