Bitcoin-IPC: Scaling Bitcoin with a Network of Proof-of-Stake Subnets

The article's title suggests a technical approach to improve Bitcoin's scalability using Proof-of-Stake (PoS) subnets. This implies a potential solution to Bitcoin's transaction throughput limitations. The use of 'ArXiv' as the source indicates this is likely a research paper, suggesting a theoretical or experimental exploration of the concept rather than a practical implementation currently in widespread use. The title is clear and concise, accurately reflecting the paper's focus.
