Blockchains have supported applications in a large set of areas, and the demand for a
framework by which blockchains interact with each other has emerged. We propose a new …

Sharding is one of the most promising technologies for significantly increasing blockchain
transaction throughput. However, as the number of shards increases, the ratio of cross-shard …

The blockchain technology has been applied to wide areas. However, the open and transparent
properties of the blockchains pose serious challenges to users' privacy. Among all the …

Transactions with deadline constraints are prevalent in blockchain-based scenarios like
