Substrate-to-Substrate cross-chain bridge (3DPass testnet - 3DPass mainnet) #8

Closed 3Dpass closed 1 year ago

3Dpass commented 2 years ago

Motivation

In order to ensure decentralized exchange testnet 3DPs (mined over the test period) for mainnet 3DPs, we need Substrate-to-Substrate cross-chain bridge to be run.

Suggested Solution

We should use an Open Source existing solutions for Substrate

Alternatives We can not see the reason, why we have to develop our own bridge, which is also possible.

Additional Information

Research required

Implement pallets: pallet-bridge-grandpa, message delivery and message dispatch. https://github.com/paritytech/parity-bridges-common/blob/master/docs/high-level-overview.md

Run syncing and validate headers from testnet inside of the mainnet runtime.

After a month of testing, we decided not to use this native Substrate bridging tools based on Grandpa finalization.
