Fusaka Just Changed the Game: ETH Now Earns Real Revenue from L2 Activity

Here's what shifted with the upgrade—and why it matters.

Every Layer 2 that settles on Ethereum uses something called blobs to post transaction data. Think of blobs as packets of info L2s send back to the mainnet.

What used to happen?
Blob fees would tank. Sometimes they'd drop so close to zero that Ethereum basically provided the service for free. L2s scaled, users benefited, but ETH holders? Not so much.

What's different now?
Fusaka introduced a fee floor. Blob costs can't collapse anymore—there's a baseline charge that sticks no matter what. And here's the kicker: that minimum gets burned, permanently removed from circulation.

So yeah, L2 growth finally feeds value back to the base layer. ETH isn't just infrastructure anymore—it's capturing economic upside from its own ecosystem expansion.
