Cryptocurrency pioneer Vitalik Buterin has urged Ethereum to prioritize privacy and resilience, arguing that a robust decentralized system is essential for it to compete with cash. He emphasizes that Ethereum should become a viable alternative currency when economic systems face instability, particularly as Nordic nations are experiencing a resurgence in cash usage due to concerns about digital system reliability. The report highlights Sweden and Norway’s growing emphasis on holding physical currency alongside their digital wallets, prompted by anxieties around the security of central banking systems in times of crisis. Buterin argues that Ethereum must prioritize private solutions and infrastructure robustness if it aspires to become a trusted substitute for traditional cash. He contends that centralized systems are inherently fragile and prone to vulnerabilities such as cyberattacks, highlighting the need for decentralized cryptocurrencies like Ethereum to address these limitations.
