Dogecoin has launched the Cardinals Index Node, a new initiative aimed at enhancing the decentralization of its blockchain network. This development allows anyone to run a node to maintain and validate the on-chain ledger, promoting a more distributed network structure. The Cardinals Index Node is designed to enable UTXO-based blockchains, such as Bitcoin, to achieve smart contract-like functionality without relying on EVM or Layer 2 solutions. The introduction of the Cardinals Index Node also includes a significant upgrade in index speed, set to reach 500 milliseconds. This enhancement is expected to improve the speed and programmability of UTXO chains, paving the way for next-generation on-chain applications. This move underscores Dogecoin's commitment to advancing blockchain technology and expanding its capabilities beyond traditional cryptocurrency functions.
