Summary: In modern business scenarios, organisations are facing the critical requirements of trustworthiness and flexibility in multi-party business processes. The Business Process Management discipline provides standardised solutions for collaboration, while blockchain technology guarantees trust in a multi-party setting. However, the immutability of blockchain hinders the flexibility of business process execution. This paper proposes an architecture for the flexible blockchain-based execution of multi-party business processes, achieving flexibility by decoupling business logic from the execution state stored in the blockchain.

Summary: With the rise of digital currencies, blockchain systems have focused on secure and efficient data storage, creating decentralized, tamper-proof, persistent, and anonymous digital ledgers. Extensive research has been conducted on query methods for blockchain platforms, resulting in significant developments and advancements. This study aims to provide a comprehensive survey of notable works and recent progress in query technologies and theories. In general, blockchain query methods rely on distributed databases, data indexing structures, and cryptographic algorithms to achieve efficient, verifiable, and secure queries. This work also addresses existing issues and challenges in query efficiency, reliability, and security, concluding with a summary of typical blockchain query scenarios and future research directions.

Summary: This paper designs and validates new block propagation protocols for the Bitcoin blockchain's P2P network, aiming to increase TPS without changing the consensus protocol. The improvements in compact-block relaying and the use of rateless erasure codes show that TPS can be increased by 100x without compromising security and consensus-building.

Summary: This paper introduces a new paradigm called Meta-Regulation for defining the behavior of a consensus system. It allows autonomous adjustment of the system behavior based on the changing capacity of the infrastructure and the community of participants. Experimental results demonstrate that using Meta-Regulation significantly improves the throughput and latency of Bitcoin, making it adaptable to the current capacity of the Internet.
