Transaction flow between main chain and sidechain

A sidechain is a separate blockchain that is connected to and interoperable with the main blockchain, also known as the main chain. The transaction flow between the main chain and sidechain involves the movement of assets and data between the two chains. When a transaction is initiated on the main chain, it can be transferred to the sidechain for processing, and vice versa. This allows for scalability and improved performance, as the sidechain can handle a specific set of transactions without burdening the main chain. The transaction flow between the main chain and sidechain is facilitated through smart contracts and consensus mechanisms, ensuring the security and integrity of the transferred assets and data.

Consensus mechanisms in sidechains

Consensus mechanisms in sidechains play a crucial role in ensuring the security and integrity of the network. These mechanisms determine how transactions are validated and added to the sidechain’s ledger. One common consensus mechanism used in sidechains is called Proof of Authority (PoA), where a set of trusted validators are responsible for validating transactions. Another popular consensus mechanism is Proof of Stake (PoS), where validators are chosen based on the number of coins they hold. These consensus mechanisms provide different levels of security and decentralization, allowing sidechains to cater to specific use cases and requirements. By implementing robust consensus mechanisms, sidechains can maintain a high level of trust and security, making them an essential component of blockchain ecosystems.

Use Cases of Sidechains
