On-chain refers to any transaction or data point that is recorded directly on the blockchain, ensuring transparency, immutability, and public verifiability. From on-chain identity (DID) to verifiable provenance of assets, the "everything on-chain" movement is the core of Web3’s trustless architecture. In 2026, sophisticated on-chain analytics tools allow users to audit protocol reserves and track capital flows in real-time. This tag focuses on the value of transparency, block explorer utility, and the distinction between on-chain execution and off-chain scaling.
