The Bank of Italy has conducted a study exploring the potential consequences if Ethereum's price were to plummet to zero. The report, titled "What if Ethereum goes to zero? How market risks can evolve into infrastructure risks," highlights the potential for validator exits, slower block production, and reduced network security. These issues could significantly impact financial services that depend on Ethereum, such as stablecoins and tokenized assets. The study suggests that regulators should consider whether financial institutions should be allowed to rely on public blockchains. It also recommends the introduction of risk mitigation strategies, including business continuity plans and validator security standards, to safeguard against such scenarios.
