Myth-Busting: Blockchain Costs“Blockchain is too expensive.”

This myth survives because most cost comparisons look at the wrong thing.

What you’re really paying for:

• Proofs vs. Storage: Put proofs (hashes/timestamps) on-chain; keep files in decentralized, permanent storage. That’s not “putting gigabytes on a ledger.”

• One-time vs. monthly: Permanent storage models are typically pre-paid once (endowment style) instead of endless $/GB-month subscriptions.

• Verification at scale: Content-addressed files are deduplicated by default—identical files don’t get stored (or paid for) twice.

  
  

5 common myths—fixed:

• “You pay per GB on the blockchain.”

 Reality: You anchor small proofs on-chain; bulk data lives off-chain on a decentralized storage layer.

• “Gas makes costs unpredictable.”

 Reality: Batch writes, anchor schedules, and L2s/permanence protocols keep costs stable and forecastable.

• “Reads are pricey.”

 Reality: Protocol fees are for writes. Reads route via gateways/CDNs you control—optimize egress like you already do.

• “Compliance adds cost.”

 Reality: Built-in, cryptographic audit trails reduce audit hours, re-verification, and dispute spend.

• “Vendor lock-in is inevitable.”

 Reality: Open formats + hash addressing = portability. If you migrate, your file’s hash (the proof) doesn’t change.

For long-lived, rarely changed data (evidence, research, records), the permanent model often wins over the 3–7 year horizon—and gives you integrity guarantees cloud alone can’t.
