Layer 1 is the foundation of blockchain infrastructure providing transaction execution and network security. The article explores Layer 1 improvements crucial for enhancing scalability and network performance.

Definition and Features

Layer 1 blockchains, like Bitcoin and Ethereum, provide the underlying infrastructure for conducting and recording transactions. Nodes in the network hold a complete copy of the ledger, ensuring transparency and trust. This infrastructure includes creating new blocks and transaction validation, which are crucial for decentralization.

Consensus Mechanisms

Layer 1 blockchains use consensus mechanisms to maintain security and data consistency across the network. The most popular ones are Proof of Work (PoW) and Proof of Stake (PoS). PoW, used by Bitcoin, requires significant computational power. PoS, utilized by Ethereum 2.0, is more energy-efficient and enables validators to create new blocks based on the number of coins held.

Layer 1 Scalability Solutions

To enhance blockchain performance, scalability solutions such as on-chain scaling and sharding are used. On-chain scaling involves optimizing the internal mechanisms of the blockchain, while sharding divides the blockchain into smaller fragments to increase overall network speed. Both approaches have the potential to significantly increase throughput.

Layer 1 blockchains play a crucial role in the crypto ecosystem by providing security and decentralization. Innovations in Layer 1 continue to evolve, offering solutions for improved scalability and efficiency.
