Deep Dive
1. BLS Signature Aggregation Upgrade (26 October 2025)
Overview: This is a mandatory network upgrade requiring all node operators to update their software. It introduces a more advanced cryptographic signature scheme that is essential for the next generation of applications on Telos, particularly those using zero-knowledge proofs and enhanced privacy.
The upgrade to BLS (Boneh–Lynn–Shacham) signature aggregation allows multiple signatures to be compressed into one, significantly improving the efficiency and scalability of the network. This is a foundational step for the planned Telos Privacy Layer and future zk-rollups. The core software, Leap, must be upgraded to version 5.0 or later; nodes that fail to upgrade will stop functioning after the network cutover.
What this means: This is bullish for TLOS because it directly enables more complex and scalable decentralized applications (dApps) to be built on the network, particularly in the growing sectors of private DeFi and identity. For users, it means the underlying infrastructure is becoming more robust and capable of handling advanced features without congestion.

2. Teloscan Explorer Major Refactor (2025)
Overview: The Telos Core Developers have refactored the official block explorer, Teloscan, to be faster, more reliable, and easier to use. This update replaces older, slower data-fetching methods with a modern Indexer API and overhauls the user interface.
Key technical improvements include refactoring the contract manager for better performance, integrating an NFT metadata scraper to load images efficiently, and enhancing the handling of token standards like ERC-20, ERC-721, and ERC-1155. The update also improves page responsiveness and adds better support for multiple languages.
What this means: This is neutral-to-bullish for TLOS as it significantly improves the developer and user experience. A faster and more intuitive block explorer makes it easier for anyone to audit transactions, interact with smart contracts, and explore the ecosystem, which can help attract and retain builders and users.

3. Privacy Layer Internal Testnet Release (15 November 2025)
Overview: Following the successful launch of its trusted setup ceremony, Telos has released an internal testnet for its Privacy Layer. This allows developers to begin building and testing applications that feature private, shielded transactions directly on the Telos Layer 1.
The privacy system is built on zero-knowledge cryptography and will enable private multi-asset accounts and transactions where amounts and participants are concealed. The internal testnet is a critical milestone before a public testnet and eventual mainnet launch.
What this means: This is bullish for TLOS because it positions the network as a contender in the crucial blockchain privacy sector. Successful implementation could attract projects and users seeking regulatory-compliant privacy for DeFi, gaming, and enterprise use cases, potentially driving new demand for the TLOS token.

Conclusion
Telos's development trajectory shows a clear focus on foundational upgrades for scalability (BLS) and a strategic push into on-chain privacy, all supported by improved core tooling. This balanced approach aims to strengthen the network's technical moat while opening new use cases. How quickly will the Privacy Layer progress from testnet to a production-ready mainnet feature?
