RSK is Bitcoin’s Fastest Growing Layer, Not Liquid nor Lightning
Since the resolution of the Bitcoin (BTC) block size limit debate in 2017, there has been a general consensus that Bitcoin is likely to scale via a multi-layer protocol stack rather than stuffing every transaction onto the base blockchain. These secondary network layers, such as the Liquid sidechain and the Lightning Network, are often referred to as layer-two networks due to the different tradeoffs made with these systems in the areas of security, efficiency, and decentralization, in addition to the fact that they effectively use the base Bitcoin blockchain as a settlement network. There has been plenty of hype around the Lightning Network as a solution for lower-value, bitcoin-denominated payments that retain many of the permissionless and low-trust properties of the Bitcoin blockchain over the past few years, and the Liquid sidechain has also achieved notable levels of adoption when it comes to the amount of bitcoin that has been pegged into the network. However, it turns out that a third layer-two Bitcoin protocol, known as RSK, is now growing faster than both Liquid and the Lightning Network. What is RSK? RSK is a Bitcoin sidechain that is compatible with the Ethereum Virtual Machine (EVM). This means that any smart contract built for Ethereum (ETH)
