Permissionless Blockchains and Secure Logging
Abstract
The blockchain technology enables mutually untrusting participants to reach consensus on the state of a distributed and decentralized ledger (called a blockchain) in a permissionless setting. The consensus protocol of the blockchain imposes a unified view of the system state over the global network, and once a block is stable in the blockchain, its data is visible to all users and cannot be retrospectively modified or removed. Due to these properties, the blockchain technology is regarded as a general consensus infrastructure and based on which a variety of systems have been built. This article presents a study and survey of permissionless blockchain systems in the context of secure logging. We postulate the most essential properties required by a secure logging system and by considering a wide range of applications, we give insights into how the blockchain technology matches these requirements. Based on the survey, we motivate related research perspectives and challenges for blockchain-based secure logging systems, and we highlight potential solutions to some specific problems.
