Blockchain is the foundation of emerging applications, such as smart contracts, nonfungible
token (NFT), and metaverse. A key issue is that blockchain requires massive storage space …

Recently, coded blockchain systems have been proposed to encode blockchain into coded
fragments and distributively store them. These fragments can be collected and decoded to …

Blockchain nodes need to store all the transactions from the beginning, which places heavy
storage loads and hinders the scalability of blockchain systems. It is difficult to directly apply …

As the blockchain technology grows, the scale of the network is becoming huger and huger,
which brings us a troublesome question: how to allocate our data into each computer of a …

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 …

This article presents a novel way to reduce blockchain nodes' memory requirements using
error correcting codes. In particular, LDPC codes are taken as examples to explicitly …

Blockchain has a broad development potential and application prospects. At present, huge
storage volume on each node has become one of the primary bottlenecks that restrict the …

A key constraint that limits the implementation of blockchain in Internet of Things (IoT) is its
large storage requirement resulting from the fact that each blockchain node has to store the …

The concept of a decentralized ledger usually implies that each node of a blockchain
network stores the entire blockchain. However, in the case of popular blockchains, which …

Traditional centralized commerce on the Internet relies on trusted third parties to process
electronic payments. It suffers from the weakness of the trust-based model. A pure …
