[#River, Bridge??] 📌Concept of Bridge & River's Innovation Points 1️⃣ What is a bridge in blockchain?? Bitcoin exists on the Bitcoin network. But what if you want to use this BTC as collateral in Ethereum DeFi? = You cannot simply move Bitcoin. * This is because the Bitcoin and Ethereum networks are separate. * Therefore, the concept of a bridge is necessary. ✔️Bridge = A system that acts as a "bridge" to transfer assets between different blockchains. 2️⃣ Why is a bridge needed?? (Process) 1) Typically, when you deposit 1 BTC into the network, 2) The bridge system holds it, 3) And issues 1 WBTC (Wrapped Bitcoin) on the Ethereum network. = In other words, the actual Bitcoin is locked in the bridge, and instead, a fake BTC (WBTC) in the form of an ERC-20 token is created on the Ethereum network. * Through this process, you can borrow against Bitcoin as collateral, provide liquidity, trade, etc., in Ethereum DeFi. 3️⃣ However, there are problems with bridges?? Bridges have been the source of many issues. This is because the structure is too complex and risky... 1) Central custody risk : If the bridge is holding Bitcoin and this central account gets hacked?? = Hacking risk 2) Smart contract vulnerabilities : Complex structures like multi-signatures, validator nodes, etc. → If just one code is breached... = Hacking risk 3) Complexity of the process = Economic inefficiency : As BTC → wrapping → bridge → collateral → minting goes through several steps, fees increase. = This is similar to how costs rise when the distribution process in real life becomes complicated. ✔️ In any case, the biggest risk is "hacking risk." 4️⃣ Why is River innovative in the bridge space?? Considering the drawbacks of these bridges, it would be best to eliminate them if possible, right? * River has eliminated the intermediate steps by replacing them with a Layerzero-based communication standard. 1) If you deposit BTC? = It immediately issues satUSD on Arbitrum. 2) Without a bridge or separate wrapping (WBTC), 3) It processes directly through communication. ✔️ In other words, BTC → satUSD (one-click structure) 5️⃣ Advantages of River without a bridge?? 1) Security = The hacking risk at the intermediate stage is eliminated. 2) Speed = Since it mints immediately, speed increases. 3) Fees = With a simpler distribution structure, fees decrease. 4) Scalability = All major chains can be connected via Layerzero. 5) Investment efficiency = Since assets are not locked, you can utilize one BTC across multiple chains. (Overall, it seems quite good^^) @RiverdotInc @River4fun
