Governance & Resource Management

Telos' governance is highly decentralized, enabled by the Telos Decide Governance Engine, which allows community members to vote on important network decisions. This structure ensures that the network adapts to the needs of users and reinforces Telos' commitment to a community-led approach to development.

Interoperability

Telos is also focused on interoperability with other blockchains, further enhancing Telos' utility in the broader blockchain ecosystem by enabling the seamless transfer of assets between different networks through initiatives like the LayerZero integration.

Security and efficiency

Telos is known for its strong security measures. Since its network launch, Telos has had a perfect operational record with no downtime, hacks, or security vulnerabilities. This is thanks to its Delegated Proof of Stake (DPoS) consensus mechanism, which not only provides fast transaction processing but also enhances network security. The DPoS system requires more than two-thirds of validators to confirm transactions and record data, thus preventing common vulnerabilities in blockchain technology such as 51% attacks.

Consensus mechanism

At the heart of Telos is its DPoS consensus mechanism. In this system, token holders vote for block producers who are responsible for maintaining the integrity of the blockchain. This voting process ensures the decentralization and security of the network, giving the community direct influence over the governance and operation of the network. This ability to democratically select block producers ensures that the network is maintained by trustworthy and committed participants.

Scalability and Interoperability

Telos supports high transaction throughput, processing over 15,200 transactions per second, making it highly scalable. This capability is crucial for applications that require fast and efficient transaction processing. In addition, Telos supports inter-blockchain communication (IBC), allowing seamless interaction and data transfer between different blockchain networks, enhancing its interoperability and making it a versatile platform for developers and users to operate in a multi-chain environment.

Environmental impact

Sustainability is one of Telos' key concerns, and it maintains a carbon neutral footprint. Telos offsets its carbon emissions every two years, in line with global efforts to reduce its environmental impact. Telos' architecture, especially the use of C++ at the grassroots level, ensures that transactions are not only secure, but also energy efficient. Each transaction on the Telos network consumes significantly less energy than traditional blockchain networks like Ethereum.

Network stability

The stability of the Telos network is a testament to its well-designed infrastructure and operating protocols. Telos' block producers play a key role in this, ensuring that the network runs smoothly without interruption. These producers are critical to processing transactions and securing the network, providing a reliable and continuous service that maintains the integrity and availability of the blockchain.

Developer Resources

Telos leverages a robust node architecture, which is fundamental to its operation and scalability. The network is powered by Nodeos, a core service daemon in the Antelope framework, which handles various critical functions such as smart contract execution, transaction validation, block production, and block confirmation.

The Telos network consists of two main types of nodes:

1. Production node:These nodes are responsible for producing blocks and are critical to the functioning of the blockchain because the new blocks they generate are verified by the network. According to the DPoS consensus mechanism, the top 21 nodes actively participate in block production at any given time.
2. Non-production Node:These nodes support the network by validating blocks and maintaining the blockchain history. Their functions include serving as API gateways, transmitting transactions, and enhancing network security through redundancy and distributed confirmation of block data.

System resources

Running a node on the Telos network requires specific system resources to ensure optimal performance and reliability:

• CPU:The processing power required depends on the type of node. API nodes without block logs can effectively run on dual-core processors, while high-intensity operations like state history nodes require at least four-core processors to efficiently handle data loads.
• RAM and Storage:Telos nodes typically require a significant amount of RAM, ranging from 16 GB for a simple API node to 32 GB or more for a node with extensive state history responsibilities. Solid-state drives (SSDs) or NVMe storage are recommended in order to efficiently handle high throughput and storage requirements, especially for nodes that manage a full transaction history.
• Network requirements:Stable and fast internet connection is crucial, requiring at least 100 Mb/s bandwidth to ensure data can be transmitted in a timely manner and synchronized with the blockchain network.

The configuration of each node may vary depending on its specific role and the current needs of the Telos network. For example, block-producing nodes must prioritize security and high processing capacity to maintain the integrity and speed of the network, while API or seed nodes focus more on connectivity and data availability. These factors are crucial for maintaining the efficiency and reliability of the Telos blockchain, ensuring its ability to scale effectively and adapt to the growing needs of users and developers. This powerful architecture not only supports the current network load but also aims to promote the growth and integration of future technologies and applications.
