On the Storage Overhead of Proof-of-Work Blockchains. (arXiv:2205.04108v2 [cs.CR] UPDATED)

Permissionless blockchains such as Bitcoin have long been criticized for
their high computational and storage overhead. Unfortunately, while a number of
proposals address the energy consumption of existing Proof-of-Work deployments,
little attention has been given so far to remedy the storage overhead incurred
by those blockchains. In fact, it seems widely acceptable that full nodes
supporting the blockchains have to volunteer hundreds of GBs of their storage,
to store and verify all transactions exchanged in the system.
