Episode Details

Coinbase’s Base network suffered two major outages last week, grinding transactions to a halt for over an hour and another 20 minutes — all due to a critical sequencer bug that triggered a cascading race condition. As Base relies on a single sequencer, any glitch in this traffic cop brings the entire network to a standstill. This isn’t an isolated incident; similar failures have plagued Arbitrum and zkSync Era. Though the team patched the core bug, recovery was delayed by infrastructure quirks. Now, they’re ramping up fuzz testing and building automated recovery systems to prevent future meltdowns. With nearly $11 billion in value at stake, these outages spotlight the fragility of layer-two tech — and the urgent need for resilience.
