Foundational Consensus Limits describe the inherent constraints or boundaries within a blockchain’s core agreement mechanism that restrict its performance, security, or decentralization capabilities. These limitations stem from the fundamental design choices of a protocol, such as transaction throughput restrictions or the number of participants required for validation. They define the practical ceiling for a network’s operational parameters. Recognizing these limits is vital for system design.
Context
The discussion around foundational consensus limits is central to the scalability debate in blockchain technology, particularly for layer-1 protocols. Developers are actively exploring alternative consensus algorithms and sharding techniques to overcome these intrinsic restrictions. Future research and implementation aim to push these boundaries, enabling greater transaction volume and broader network participation without compromising security or decentralization. This ongoing effort seeks to enhance blockchain performance.
This research formalizes the Dynamic Availability and Reconfiguration (DAR) model, proving the minimum security assumptions required for scalable, decentralized Proof-of-Stake consensus.
