Sei (SEI) sustainability report

Sei is present on the following networks: Sei.

The Sei blockchain network employs a sophisticated "Twin-Turbo" consensus mechanism, specifically engineered to deliver high performance and robust security by integrating advanced transaction processing techniques with the proven reliability of Tendermint Core. This innovative approach differentiates Sei within the blockchain landscape by prioritizing speed and efficiency without compromising on fundamental security principles. At the heart of the Twin-Turbo Consensus are several key components designed to optimize transaction throughput and finality. Optimistic Block Processing allows validators to process transactions with an assumption of their validity, which significantly reduces latency and boosts the overall transaction per second (TPS) capacity of the network. This 'assume valid unless proven otherwise' strategy streamlines the block production process, allowing for quicker block propagation. Complementing this is Intelligent Block Propagation, where block proposals are compressed, often containing only transaction hashes. This enables validators to reconstruct blocks locally, which drastically expedites the consensus process by minimizing the data transfer required between nodes. Furthermore, Sei achieves Single Slot Finality, a critical feature that ensures transactions are irrevocably finalized as soon as a block is added to the chain. This eliminates the need for subsequent confirmations, a common practice in many other blockchain protocols, and substantially mitigates the risk of chain reorganizations, thereby enhancing the network's reliability and trust. Underpinning these performance enhancements is the robust integration of Tendermint Core. This integration provides crucial Byzantine Fault Tolerance (BFT), which is essential for maintaining the security and resilience of the network. By leveraging Tendermint Core, Sei is safeguarded against malicious actors, ensuring that the network can continue to operate correctly even if a significant portion of its validators (up to one-third) are compromised or behave maliciously. This combination of speed-oriented innovations and battle-tested security frameworks positions Sei as a high-performance, secure blockchain network designed for demanding decentralized applications.

The Sei Network maintains its decentralized ecosystem and operational integrity through a meticulously designed system of incentive mechanisms and a transparent fee structure. These mechanisms are crucial for encouraging active participation from network constituents, including validators, delegators, and the broader user base, ensuring the continuous security, stability, and evolution of the blockchain. A primary incentive is the distribution of Staking Rewards. Validators, who are responsible for processing transactions, producing blocks, and maintaining network security, are compensated with SEI tokens for their efforts. Similarly, delegators, who choose to stake their SEI tokens with these validators, also receive a proportional share of these rewards. This system not only incentivizes validators to uphold their responsibilities diligently but also encourages broader community engagement through delegation, strengthening the network's security posture by decentralizing stake. Furthermore, the Sei network places a significant emphasis on community-driven development through Governance Participation. Holders of SEI tokens are empowered to actively participate in crucial network governance decisions. This includes voting on proposed protocol upgrades, changes to network parameters, and other key strategic directions, fostering a genuinely community-owned and developed blockchain environment. This mechanism aligns the long-term interests of token holders with the sustained growth and health of the Sei ecosystem. In terms of Applicable Fees, users engaging in various activities on the Sei network are required to pay Transaction Fees. These fees, denominated in SEI tokens, are levied for all network transactions, encompassing a wide range of operations. The collected transaction fees are then distributed among validators and their respective delegators as additional rewards. This dual reward system—combining staking rewards with a share of transaction fees—serves a vital role in financially supporting network operations and reinforcing its security infrastructure. By ensuring a direct financial incentive for those who secure and maintain the network, Sei aims to foster a sustainable and robust operational framework that encourages consistent participation and commitment from its key stakeholders.

The methodology for calculating the energy consumption of the Sei blockchain network adopts a "bottom-up" approach, primarily considering the energy expenditure of network nodes as the central determinant. This comprehensive method is informed by empirical data gathered from various sources, including publicly available information sites, open-source crawlers, and proprietary crawlers developed in-house. The process begins by identifying the hardware requirements necessary to run the client software for the network. The energy consumption of these specific hardware devices is then meticulously measured in certified test laboratories, providing a foundational baseline for the overall energy footprint. To ensure accuracy and comprehensive coverage, the calculation process leverages the Functionally Fungible Group Digital Token Identifier (FFG DTI) when available. This identifier helps to determine all relevant implementations of the asset within the scope of analysis. The mappings associated with the FFG DTI are regularly updated based on data provided by the Digital Token Identifier Foundation, ensuring that the energy consumption model remains current and reflective of the network's evolving architecture. The estimations regarding the types of hardware utilized and the total number of participants in the network are derived from assumptions, which are diligently verified using the best available empirical data. A general underlying assumption is that network participants are largely economically rational, guiding the modeling of their operational choices. Furthermore, a precautionary principle is consistently applied throughout the methodology. In instances of uncertainty or doubt, assumptions are made on the conservative side, meaning higher estimates are used for potential adverse impacts. This approach ensures that the reported energy consumption figures are robust and err on the side of overestimation rather than underestimation. When calculating the energy consumption specifically attributable to a crypto-asset like SEI, the initial step involves computing the energy consumption of its underlying network (e.g., Osmosis, as mentioned in the document for certain implementations). Subsequently, a fraction of this total network energy consumption is then attributed to the specific token, based on its activity and share within that network, ensuring a nuanced and proportional assessment of its energy footprint.
