Block Chain - Sidechains

Sidechains are independent blockchains that run parallel to a main blockchain and are connected to it through a two-way mechanism. They allow assets and data to move between chains while keeping the main blockchain unchanged and secure.

Purpose of Sidechains
The main purpose of sidechains is to improve scalability and flexibility. Instead of forcing every new feature or experiment onto the main blockchain, sidechains allow developers to test new ideas, rules or upgrades without risking the stability of the primary network.

How Sidechains Connect to the Main Chain
Sidechains are linked to the main chain using a two-way peg system. Assets are locked on the main chain and an equivalent value is created on the sidechain. When assets are moved back, they are unlocked on the main chain and removed from the sidechain.

Independent Rules and Consensus
A sidechain can have its own consensus mechanism, block size, transaction speed and smart contract rules. This independence allows sidechains to process transactions faster or support features that the main chain does not allow.

Security Model of Sidechains
Sidechains do not always inherit the full security of the main chain. Their security depends on their own validators or consensus system. If a sidechain is compromised, the main chain remains safe, but assets on the sidechain may be at risk.

Use Cases of Sidechains
Sidechains are commonly used for scaling solutions, gaming platforms, decentralized finance experiments and feature testing. They help reduce congestion on the main blockchain while still allowing interaction with it.

Why Sidechains Are Important
Sidechains enable innovation without disrupting the core blockchain. They improve performance, support experimentation and help blockchains evolve while preserving the security and stability of the main network.

Conceptual Example
A blockchain locks coins on the main network and makes the same value available on a sidechain. Transactions are processed quickly on the sidechain, and when finished, the final balance is moved back to the main chain without changing its core rules.
