Cross Chain - Bridging between Blockchains

• Markdown으로 보기이 페이지를 일반 텍스트로 보기

Imagine different islands, each with its own unique economy and currency. To trade with each other, these islands need bridges to connect them. In the world of blockchain, these islands are different blockchains, and the bridges are called cross-chain bridges.

Why do we need cross-chain bridges?

• Asset movement across chains: Cross-chain bridges let you move digital assets between different blockchains, similar to transfers between bank accounts but with chain-specific risks and wait times.
• Expanded Opportunities: By connecting different blockchains, you can access a wider range of financial services, decentralized applications (dApps), and investment opportunities.

How do cross-chain bridges work?

• Lock and Mint: When you want to move assets from one blockchain (let's call it Chain A) to another (Chain B), the bridge locks your assets on Chain A and mints a corresponding amount of wrapped assets on Chain B.
• Transfer and Burn: You can then transfer these wrapped assets on Chain B. Once you're ready to move them back to Chain A, the bridge burns the wrapped assets on Chain B and releases your original assets on Chain A.
