Blocknative introducing a new way to get gas price estimation, using block prediction instead of time estimates.

This could definitely change the way gas price is shown and selected in dApps.

As we've seen in the past week good gas price oracle solutions are critical to the ecosystem, really glad to see this from Blocknative ... OpenZeppelin Defender will include it in its gas price oracle pool

Zach Krasner

Remember 10 years ago when a package delivery was just a black hole with no info on estimated delivery? That’s where Ethereum gas is today, but @blocknative’s introducing a game-changer
