LibraBridge: 連接 Libra 與 Ethereum

在前面的文章中,我們介紹過 LibraSwap,但實際上透過 Libra SPV,我們可用於搭建 Libra 與 Ethereum 之間的橋樑,稱做 LibraBridge。利用 SPV validation 實作跨鏈的代幣交換不是新的創舉,過去有許多項目利用這個方法來橋接兩個不同的鏈上資產,如下。SPV 是一種用於輕節點驗證交易的方法,透過智能合約的協助,我們可以在合約上驗證來自 Libra 的交易。

LibraBridge: Connect Libra with Ethereum

In the previous article, we explain the concept of the LibraSwap. Next, we will introduce LibraBridge, which can be used to connect Libra with Ethereum by Libra SPV method. The idea to leverage SPV validation to implement cross-chain transfer is not new. It’s already done by several projects listed below. SPV proof is a way for light client to verify if interested transaction happened on the blockchain. With the help of smart contract, Libra SPV proof can be implemented on Ethereum. Namely, we can verify a Libra transaction through smart contract, along with some external information.
