A protocol that lets two blockchains send messages to each other directly, with no bridge in the middle. Each network checks for itself that what it receives is authentic.
Two blockchains talk directly, each verifying the other’s state with cryptographic proofs. No bridges, no locked liquidity, no intermediary validators.
A mail service between blockchains. Hedera sends messages, payments or data to another network, and each side checks for itself that they are authentic. No middlemen you have to trust blindly.
Step through it. Switch to “Unfunded Connector” to see what happens when someone doesn’t pay.
Press Next. Also try “Nobody pays” to see what happens if payment fails.
Each message is chained: SHA-256(previous hash ‖ payload). The state proof only certifies the last hash. Edit a message “in transit” and see what the destination ledger does.
Each letter carries a seal that depends on the previous letter. The official seal only certifies the last one. Change a letter on the right, as if someone tampered with it along the way, and see what happens.
| Typical bridge | CLPR | |
|---|---|---|
| Who do you trust? | The intermediary running the bridge | Only the two blockchains |
| What happens to your money? | It gets locked and you receive a copy | Messages travel; each app decides what to do |
| If someone cheats | They can steal if they control the bridge | At most they cause delays; forging is impossible |
| Is there a new token? | Often, yes | You pay in each network’s own currency |
| Honest parties needed | Most of those watching over the bridge | Just one honest mail carrier per city |
| Who you trust | The bridge’s validators or multisig | Only the two ledgers and their verifier |
| Assets | Locked tokens + wrapped | Messages; asset logic is up to the app |
| Malicious node | Can steal funds if it controls the quorum | Can delay, never forge |
| Own token | Often, yes | None; fees paid in the native token |
| Honest parties needed | Majority of the validator set | One honest endpoint per ledger |
Think of each blockchain as a city. CLPR is the postal service that connects them. Under each piece you’ll find its technical name.
Only what is stated in the specification, the LFDT lab proposal or the official announcement. Each answer cites its source.Everything comes from the official documents. Under each answer you’ll see where it comes from.
