Blockchain serves as a replicated transactional processing system in a trustless distributed
environment. Existing blockchain systems all rely on an explicit ordering step to determine …

Blockchain technologies are expected to make a significant impact on a variety of industries.
However, one issue holding them back is their limited transaction throughput, especially …

Many existing blockchains do not adequately address all the characteristics of distributed
system applications and suffer from serious architectural limitations resulting in performance …

Performance and scalability are major concerns for blockchains: permissionless systems are
typically limited by slow proof of X consensus algorithms and sequential postorder …

Permissioned blockchains are becoming popular as data management systems in the
enterprise setting. Compared to traditional distributed databases, blockchain platforms …

Unlike blockchain systems in public settings, the stricter trust model in permissioned
blockchain opens an opportunity for pursuing higher throughput. Recently, as the consensus …

Scalability is one of the main roadblocks to business adoption of blockchain systems.
Despite recent intensive research on using sharding techniques to enhance the scalability of …

Sharding scales throughput by splitting blockchain nodes into parallel groups. However,
different shards' independent and random scheduling for cross-shard transactions results in …

Existing blockchain systems scale poorly because of their distributed consensus protocols.
Current attempts at improving blockchain scalability are limited to cryptocurrency. Scaling …

Blockchain technology has emerged as the cornerstone of many decentralized applications
operating among otherwise untrusted peers. However, it is well known that existing …
