Kraken, one of the oldest crypto exchanges, is set to launch its own blockchain named Ink early next year, aimed at facilitating decentralized applications for trading, borrowing, and lending tokens without intermediaries. The blockchain will utilize technology similar to Coinbase's Base, which has emerged as a leading DeFi platform since its launch. A testnet for developers will be available later this year, with the full platform expected to open to users in the first quarter.
