Progressing to Leap 6: EOS Set to Unveil Savanna’s Instant Finality on July 31st
In Brief
Leap 6 brings forth Instant Finality through Savanna, a pioneering consensus algorithm designed to emulate the smooth, user-friendly experience typical of web2 in the evolving web3 landscape.

Introducing Savanna: A Leap Towards Instant Finality and More
Leap 6 heralds the arrival of Instant Finality with Savanna (Scalable Agreement on Validated Additions with Nimble Nonrepudiating Attestation), an innovative consensus algorithm that revolutionizes blockchain interaction by providing a user experience akin to web2. Built on the foundations of the HotStuff consensus mechanism conceived by VMware Research, Savanna is set to transform blockchain technology. This brand-new algorithm modernizes traditional block-based consensus chains, utilizing the latest advancements in distributed systems. By integrating aggregate BLS signatures alongside cutting-edge cryptographic techniques, it significantly boosts scalability while drastically reducing transaction finality time. With this update, the EOS Network will witness transactions becoming irreversible within seconds—a remarkable 100-fold enhancement from prior versions. Such advancements will not only amplify network efficiency but also elevate the overall user experience, ensuring EOS remains a leader in blockchain innovation.
Boosted Privacy Features and Cryptographic Progress
Leap 6 also showcases extraordinary potential for cryptographic breakthroughs. The rollout of aggregate BLS signatures, verifiable in as little as 1.1ms*, creates a foundation for more abstract cryptographic frameworks, paving the way for the development of ZK proof systems. This is achieved via EOS's proprietary adaptation of BLS processes alongside specialized matrix operations executed in WebAssembly. The implications are profound, fostering enhanced privacy attributes like confidential transactions and private address usage, effectively setting new standards in blockchain privacy and security.

Facilitating an Adaptive Blockchain Framework with New Roles on the Horizon
Leap 6 signifies a major development within the EOS framework by allowing for a potential overhaul of the conventional Block Producer role. This evolution provides the EOS community with the option to distinguish responsibilities into two separate functions: Block Proposers and Block Finalizers.
The implementation of this structure is not automatic with Leap 6; rather, it offers the community the freedom to adopt it if a consensus is reached. The introduction of distinct roles for Block Proposers and Block Finalizers could lead to a more decentralized, secure, and efficiently managed network.
- Block Proposers – responsible for arranging transactions into proposed blocks and collaborating with Block Finalizers to create Quorum Certificates, which serve as conclusive evidence that a block proposal has been finalized.
- Block Finalizers – focus on endorsing the proposed blocks by submitting their signatures to the Block Proposer to generate Quorum Certificates. This clear division of roles aims to enhance the security and efficacy of the network by establishing a robust mechanism for validating and finalizing blocks.
In Leap 6, the processes of proposing and finalizing blocks are treated as separate tasks. This strategic separation allows the EOS blockchain to achieve unprecedented levels of safety and liveness, creating a more predictable operational environment. Additionally, it enables seamless inter-blockchain communication and allows observers to monitor and maintain network health without needing to engage in transaction creation.
Looking Forward: The Bright Future of EOS and Antelope Chains
Leap 6.0 marks a notable shift for the EOS network, enhancing both efficiency and decentralization with the advent of the Savanna consensus algorithm. This innovation significantly speeds up transaction finality, which, in turn, enhances network performance and overall user satisfaction. Beyond being just a technical upgrade, Leap 6.0 reinforces the community-focused and autonomous spirit of EOS, demonstrating the network's skill in adopting advanced consensus techniques. Backed by robust technical infrastructure and collaborative efforts from EOS Network node operators, Leap 6.0 sets the stage for a smooth transition, establishing new standards for speed and security while shaping the next chapter in blockchain technology development.

EOS Network
The EOS Network is a third-generation blockchain platform powered by EOS VM, a low-latency, high-performance WebAssembly engine designed for the deterministic execution of nearly fee-less transactions—optimized specifically for an ideal Web3 user and developer experience. As the flagship blockchain and financial core of the Antelope framework, it serves as the engine behind collaborative multi-chain initiatives and public goods financing through the EOS Network Foundation (ENF).
EOS EVM
The EOS EVM mirrors the capabilities of the Ethereum EVM within an EOS smart contract. It offers feature parity with other EVMs but excels in speed, performance, and compatibility. The EOS EVM bridges the EOS ecosystem with Ethereum by enabling developers to launch a variety of Solidity-based digital assets and cutting-edge dApps on EOS. Developers can leverage the EOS EVM to tap into Ethereum’s robust open-source code, tools, libraries, and SDKs, all while benefiting from EOS's superior performance.
EOS Network Foundation
The EOS Network Foundation (ENF) was created with the vision of a thriving and decentralized future. Through engaging key stakeholders, implementing community programs, providing ecosystem funding, and supporting an open technology environment, the ENF is driving the transformation of Web3. Established in 2021, the ENF serves as the nexus for the EOS Network, a leading open-source platform equipped with a comprehensive suite of tools, frameworks, and libraries for blockchain deployment. Together, we are fostering innovations crafted by our community and are dedicated to forging a more resilient future for all.
