Crypto Finance, a subsidiary of Deutsche Börse Group, announced the launch of Chainlink Proof of Reserve, with nxtAssets, a crypto asset ETP issuer, as its first user. This allows investors to independently verify Crypto Finance's Bitcoin and Ethereum spot reserves on-chain, enhancing transparency and security. Reserve data is provided by Chainlink's decentralized oracle and published on the Arbitrum Network. Officials stated that this mechanism offers greater transparency and security than traditional periodic disclosure methods, providing a clearer foundation of trust for investors, regulators, and auditors.
