How the bridge works.
Proofs, custody rules and the two crossing routes. Eight graphics in Paper and Ink, with vector and PNG downloads.
Every block carries its proof.
Pearl certificates, TEE verification, a vendor quorum and minting on Ethereum.
Two chains. Distinct checks.
Where work proofs, checkpoint signatures and transaction proofs are checked.
The vault has rules.
A capped withdrawal, a fixed payout list and a review window before payout.
A wrong batch goes back.
An independent watchtower can sweep an unexpected batch before the window closes.
New keys have to wait.
Delayed rekeying, a watchtower veto and the separate council recovery path.
Two directions. Five steps each.
The deposit and redemption routes, with the chain and custody steps identified.
Consensus, with proof behind it.
What TEE verification and covenant rules constrain, and what remains trusted.
The wait is part of the design.
Confirmations, caps, cancellation windows and pause behaviour.
The proof path in motion.
Each stage receives a slow outline. The labels stay visible throughout. The SVG follows reduced motion preferences; every loop also has a static PNG.
Play loop
Play loop
Six seconds per loop at 1200 × 675. The loop explains a sequence; its duration is not a transfer estimate. Close “Play loop” to hide it.
Keep the checks distinct.
Use the mechanism and its trust assumptions together.
Work proofs and signatures
Attesters verify Pearl’s work certificates inside TEEs. Ethereum checks their checkpoint signatures and the deposit’s inclusion proof. Ethereum does not verify Pearl’s mining certificate directly.
Script rules and watchtowers
The covenant constrains funds. A watchtower checks whether the batch matches Ethereum and must act inside the window. The signer quorum, governance, correct code and independent chain data still matter.
D, D2 and DRekey are configured delays in blocks. Keep those symbols when no deployment parameters are supplied. The editable SVGs retain text; the display SVGs outline it for consistent rendering. Use the bundled Manrope and Geist Mono fonts to edit labels.
