A debate has been heating up on crypto Twitter about Real Economic Value (REV) — a metric meant to measure the value blockchains accrue from user activity. REV includes transaction fees and MEV tips, but excludes issuance — the inflationary rewards paid to validators. Some say it’s the clearest window into genuine usage. Others argue it’s a flawed and misleading proxy.

So we brought the argument to Unchained. Tom Dunleavy, Head of Venture at Varys Capital, says fees are headed to zero, and blockchains shouldn’t be valued like companies. Meanwhile, Austin Federa, Co-founder of DoubleZero, believes REV offers a real lens on activity, maturity, and demand.

The conversation covers:

Whether REV is a meaningful metric (and how to game it)

Whether L2 tokens are fundamentally broken

What happens to security when fees (and MEV) go to zero

If high REV signals product-market fit or just economic noise

How to value blockchains, if not with REV
