Bitcoin With Heterogeneous Block Sizes: A Scaling Proposal

TL;DR

This paper proposes a scalable Bitcoin model where blocks are composed of variable-sized sub-blocks, allowing miners and users to choose their preferred trade-off between decentralization and throughput without network disruption.

Contribution

It introduces a novel block structure with heterogeneous sub-block sizes, enabling flexible scalability and individual choice in Bitcoin transactions.

Findings

Supports scalability with variable block sizes

Maintains network stability despite heterogeneity

Allows individual customization of block size preferences

Abstract

We propose a bitcoin generalization as a solution to the problem of scalability. The block is redefined as a sequence of sub-blocks of increasing sizes that coexist as different levels of compromise between decentralization and transactions throughput. Miners and users can decide individually the sizes they use without affecting others in the network.
