A fundamental issue in blockchain systems is their scalability in terms of data storage,
computation, communication, and security. To resolve this issue, a promising research …

Today's blockchain designs suffer from a trilemma claiming that no blockchain system can
simultaneously achieve decentralization, security, and performance scalability. For current …

We introduce the concept of “coded computing”, a novel computing paradigm that utilizes
coding theory to effectively inject and leverage data/computation redundancy to mitigate …

Light nodes in blockchain systems are known to be vulnerable to data availability (DA)
attacks where they accept an invalid block with unavailable portions. Previous works have …

Recently, the blockchain technology, which can decentralize business ecosystems using
secure transactions without trusted intermediaries, has been spotlighted. Full nodes play an …

The Bitcoin system uses a fully replicated data storage mechanism in which each node
keeps a full copy of the blockchain. As the number of nodes in the system increases and …

A popular method of improving the throughput of blockchain systems is by running smaller
side blockchains that push the hashes of their blocks onto a trusted blockchain. Side …

Blockchain is considered to be able to solve the problem of trust between distributed nodes.
However, it's a challenge to store the large amount of data produced by blockchain …

Node synchronization is essential for the stability of the Bitcoin network. Critics have raised
doubts about the ability of a new node to quickly and efficiently synchronize with the Bitcoin …

传统区块链存在存储可扩展性难题, 现有研究基于纠删码理论降低了区块链存储开销,
但在区块的译码恢复时会带来高额的计算与通信开销. 为解决以上难题, 提出了一种基于级联 …
