內容上會偏向對於技術進行解析，但會力求使用簡單好懂的方式來表述。
很高興可以和大家聊聊跨鏈，2021，跨鏈不再只是資產跨鏈，像是如何兼容 EVM，讓用戶使用既有的錢包（e.g.Ｍetamask) 都會是跨鏈技術很重要的進展。

slido url – Abstract –本次的演講主要聚焦在區塊鏈的跨鏈技術在近幾年來的升級。
跨鏈不難，BTC 到以太坊上的 WBTC、RenBTC 已經向我們傳達了這個訊息，然而 Polkadot 的 Substrate 以及 Cosmos 的 Hub 等獨立的跨鏈標準卻又讓我們看到了瓶頸。從這兩個案例上，我們看到了跨鏈如果是限定在一套特定的標準下，那麼基本上我們會看到一個又一個割裂的區塊鏈世界，也就是你有你的標準，我有我的標準，從此陷入各自為政的局面。然而，從去年開始，隨著 DeFi 的加溫，以太坊這條公鏈的生態已經成為了最強的護城河，本次的演講中會去剖析，在這樣的局面下，其他的新功鏈如 BSC、Fantom 、Near 以及 Nervos，如何在最簡單的用戶操作環境下完成跨鏈，以及他們如何同時在不同的底層模型下都同時發展出了 EVM 兼容的技術，以及在不同的底層設計下去兼容既存錢包，例如 Ｍetamask、ImToken 以及 ＷalletConnect，而非重複造輪子讓使用者下載新的錢包。同時，在 Rollup(zk rollup,optimistic rollup 以及 Matic、Xdai 等側鏈同時在蓬勃的發展下，這些公鏈具有什麼樣的價值。最後，我也會去介紹 Chainlist、Multichain.xyz 等工具如何促進 dApps、用戶以及他們的資產在不同區塊鏈之間的互操作性。
This presentation mainly focuses on the upgrading of blockchain cross-chain technology in recent years.
Cross-chain is not difficult, as WBTC and RenbTC on Ethereum from BTC already tell us, but independent cross-chain standards such as Polkadot Substrate and Cosmos Hub present bottlenecks. What we've seen in these two cases is that if cross-chains are limited to a specific set of standards, then basically we're going to see one fragmented blockchain world after another, where you have your standard and I have my standard, and then we're going to have a fragmented blockchain world. However, since last year, with the heat up of DEFI, the ecosystem of the Ethereum public chain has become the strongest moat. This presentation will analyze how other new power chains, such as BSC, FANTOM, Near and Nervos, can complete cross-chain in the simplest user operation environment. And how to simultaneously develop EVM compatible technology in different underlying models, as well as compatible existing wallets such as MetaMask, ImToken, and WalletConnect in different underlying designs, rather than reinvent the wheel for users to download new wallets. At the same time, under the vigorous development of ROLLUP (ZK ROLLUP,optimistic ROLLUP, MATIC, XDAI and other side chains, what is the value of these public chains? Finally, I'll look at how tools like ChainList, multichain.xyz, and others can facilitate interoperability between dApps, users, and their assets across different blockchains.
