Coinbase has launched a new metric for blockchain analytics: the H-Index, a new tool designed to provide a more accurate measure of blockchain network health by focusing on genuine customer engagement. While traditional metrics such as daily trading volume are vulnerable to witch attacks or airdrop campaigns that distort real user activity, the H-index responds by taking into account both the number of addresses and the diversity of senders. However, the H-index is currently not perfect, and large wallets and different blockchain architectures can still distort data.
