Deutsche Telekom MMS has partnered with decentralized data platform Subsquid to run dedicated worker nodes and become part of Subsquid's decentralized "data lake", aiming to improve the security and efficiency of blockchain data retrieval and transmission. Subsquid co-founder Marcel Fohrmann said that this cooperation will strengthen and protect permissionless data access on Web3. In addition, Deutsche Telekom recently decided to become a validator of Ethereum Layer 2 expansion platform Polygon. Subsquid co-founder Dmitry Zhelezov emphasized that all data is cryptographically verified to ensure authenticity. Although security remains the most important issue, they have implemented strict security audits and maintain a 24/7 on-call team to ensure the normal operation of the blockchain infrastructure.
