Explanation of “Mainchain” in the Crypto World

Jakarta, Pintu News – Mainchain is the term for the base layer (main blockchain) in cryptocurrency architecture, where all transactions are recorded, processed, and finalized. Mainchain is often referred to as the parent blockchain or the main backbone of a blockchain network. The most common examples are the Bitcoin (BTC) or Ethereum (ETH) blockchains.

Mainchain Functions and Characteristics

Mainchain is the main place for recording transaction data so that all blocks and transaction records are permanently stored. Once data is recorded on the mainchain, it cannot be changed. This layer also provides security, privacy, and a high level of decentralization for the entire crypto ecosystem.

However, the mainchain can become slow if there are too many transactions, as it has to process all the activity directly. This is whysecondary layers solutions are created, such as the Lightning Network in Bitcoin. This layer speeds up the transaction process outside of the mainchain, but the final settlement is still done on the mainchain.

Mainchain Limitations and Solutions

Mainchain has several limitations, such asblock size, low throughput (number of transactions that can be processed per second), and high energy requirements. To address these scalability issues, a separate sidechain-blockchainsolution was developed that connects to the mainchainvia a two-way peg mechanism, thereby increasing the efficiency and scale of the network without sacrificing security.

Conclusion

The mainchain is the foundation of every blockchain and cryptocurrency ecosystem. While it provides the best level of security and decentralization, challenges on scalability and speed remain a major concern. Therefore, layer 2 and sidechain development continues to support the growth of a more efficient crypto ecosystem.
