q&a

What is the ultra sound relay?

The ultra sound relay is a credibly-neutral and permissionless relay—a public good from the ultrasound.money team.

What software is the ultra sound relay running on?

What is a credibly-neutral relay?

A credibly-neutral relay only validates blocks against consensus rules as in enshrined proposer-builder separation.

What is enshrined proposer-builder separation?

Enshrined proposer-builder separation (PBS) is an in-consensus PBS without relays, removing relay weak censorship.

What is weak censorship?

Weak censorship is mild transaction censorship which increases on-chain inclusion delay of censored transactions.

How delayed are censored transactions?

Censorship in X% of blocks yields 1/(1-X%) larger average delay. If X% = 80%, delay grows 5x from 12 sec to 1 min.
