What Is a Sidechain? A sidechain is linked to the main blockchain, known as the mainnet or parent chain, using a two-way peg. Sidechains were created to solve the critical issue of speed faced by the #crypto world. Instead of having all processes on the main blockchain, a sidechain is used to simplify calculations while offering the same security as the main blockchain. Sidechains can interact in different ways. However, at the core is the ability to exchange assets between chains with the help of a two-way peg. This peg comprises lockboxes on both chains. To understand how a lockbox works, imagine you are moving 1 $BTC from the main #network to a sidechain. First, you send the $BTC to a lockbox address. Any $BTC sent here is taken out of the total supply temporarily. Information regarding the sidechain address where you will send the $BTC is included during the transaction. Once the transaction is complete, the sidechain lockbox will #release 1 $BTC and send it to an address on the main network. How Do Sidechains Work? The main chain user first needs to send coins or other digital assets to an output address where they are locked and unspendable anywhere else. After the transaction is complete, a confirmation is relayed across the chains. This is followed by a waiting period for added security. Afterward, the coins or assets will be fully transferred on the sidechain, enabling users to #move them around freely on the new network. Sidechains come in many variations depending on the functions they are built for. While both #Liquid and Rootstock are #Bitcoin sidechains, they #function very differently since the latter is specifically created for the purpose of running #smart contracts more efficiently. Examples of Sidechains#Liquid #NetworkAn example of a sidechain is the #Liquid Network, a #protocol built on top of the #Bitcoin network. The block discovery period on this sidechain is just one minute, which is ten times faster than the main #Bitcoin network. #Polygon#Polygon is an #Ethereum sidechain designed to bring #scaling solutions to public blockchains. It provides scalability while ensuring users have a better experience without compromising security. While it currently supports Ethereum, there are plans to support other blockchains to ensure #blockchain interoperability and scalability. #CryptoRecovery $MATIC $ETH
