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 …

Recently, stateless blockchains have been proposed to alleviate the storage overhead for
nodes. A stateless blockchain achieves storage-consensus parallelism, where storage …

State sharding is a common solution to the scalability problem in blockchain systems,
allowing nodes to hold a partial view of the system state. With sharding, the processing of a …

Sharding is an effective technique to improve the scalability of blockchain. It splits nodes into
multiple groups so that they can process transactions in parallel. To achieve higher …

Sharding is a prominent technique for scaling blockchains. By dividing the network into
smaller components known as shards, a sharded blockchain can process transactions in …

Proposals for ultralarge-scale-system (ULSS), particularly the grid's energy management
systems (EMSs), to adopt the Ethereum blockchain are increasing as its support for privacy …

Permissioned blockchains are being widely applied to solve the trust problem in enterprise
collaboration. However, most of these systems suffer from low throughput and flexibility …

Sharding provides an opportunity to overcome the inherent scalability challenges of the
blockchain, which is the infrastructure for the next generation of the Web. In a sharding …

(1) Background: To solve the blockchain scaling issue, sharding has been proposed;
however, this approach has its own scaling issue: the cross-shard communication method …

Blockchain is known for its potential to create high transparency, decentralization, and
unprecedented security. However, it is still confronted with scalability problems which pose a …
