Technical Details of the Dencun Upgrade
To better understand the technical aspects of the Dencun upgrade, it is essential to delve into the specific components and mechanisms that will be introduced. This section provides a detailed overview of the key technical elements of the upgrade.
Sharding
Sharding is a technique that divides the Ethereum blockchain into smaller, more manageable pieces called shards. Each shard operates as an independent blockchain, processing its own transactions and smart contracts. This parallel processing capability significantly increases the network’s throughput and scalability. The Dencun upgrade will introduce a multi-phase sharding implementation, with the initial phase focusing on data availability and the subsequent phases enabling full smart contract execution on shards.
eWASM
The Ethereum WebAssembly (eWASM) is a new virtual machine designed to replace the existing Ethereum Virtual Machine (EVM). eWASM leverages the WebAssembly (Wasm) standard, which is widely used in web development for its performance and efficiency. By adopting eWASM, Ethereum aims to improve the performance of smart contract execution, reduce gas costs, and provide a more developer-friendly environment. eWASM also supports a broader range of programming languages, making it easier for developers to build and deploy dApps on the Ethereum network.
Beacon Chain
The Beacon Chain is a PoS blockchain that runs in parallel with the existing Ethereum PoW chain. It serves as the backbone of Ethereum’s PoS consensus mechanism, coordinating validators and managing the network’s overall security. The Beacon Chain is responsible for managing the registry of validators, processing validator deposits and withdrawals, and facilitating crosslinking between shards. The introduction of the Beacon Chain is a critical step in Ethereum’s transition to a PoS consensus mechanism, which aims to improve the network’s security, scalability, and energy efficiency.
Crosslinking
Crosslinking is a process that allows shards to communicate with each other, ensuring data consistency and enabling seamless interaction between different parts of the network. Crosslinks are periodic summaries of the state of a shard, which are included in the Beacon Chain. These summaries allow validators to verify the state of other shards without having to process all the transactions within those shards. Crosslinking is essential for maintaining the integrity and coherence of the Ethereum network as it scales through sharding.
Improved Gas Efficiency
The Dencun upgrade introduces several optimisations to reduce gas costs, making transactions more affordable for users and developers alike. These optimisations include improvements to the gas cost calculation algorithm, more efficient data storage mechanisms, and enhanced transaction batching techniques. By reducing gas costs, the Dencun upgrade aims to lower the barrier to entry for users and developers, encouraging greater participation and usage of the Ethereum network.
