Blockchains don’t prove things by existing. They prove things by what they natively enforce. If blockchain is meant to function as a genuine proof-of-X infrastructure, it must be grounded in native onchain assets and enshrined mechanisms that the protocol itself enforces. These are what give blockchain its unique neutrality properties, along with central trust minimization and open verifiability. Without them, you’re merely attaching external claims to a ledger; claims that could just as easily live off-chain in a conventional database. In that scenario, invoking “the blockchain” as the source of truth becomes performative rather than substantive, blurring the line between simple record-keeping and real authenticity. This is precisely where Ethereum stands apart. Its unwavering commitment to native enshrinement, strong neutrality, and protocol-level guarantees makes it the best platform to serve as a true proof-of-X substrate. The call to action is simple: build natively, anchor truth onchain, and let Ethereum do what it was designed to do: turn verifiable truth into shared infrastructure.
