Tezos Activates ‘Mumbai’ Upgrade Enabling More Than a Million Transactions Per Second
29.3.2023 22:45:00 EEST | Business Wire | Press release
Tezos, a pioneering blockchain for Proof-of-Stake consensus and on-chain governance, has activated Mumbai, its thirteenth core protocol upgrade. The Mumbai upgrade introduces Smart Rollups, a new Layer 2 scaling solution built directly into the protocol, which puts Tezos at the forefront of optimistic rollup technology.
Smart Rollups enable decentralized applications (dApps) to benefit from their own dedicated hardware resources in order to process a high amount of transactions, while the integrity and security of the Smart Rollup is guaranteed by the Tezos main chain, or Layer 1.
Due to this approach, the Tezos ecosystem will be able to surpass the milestone of one million transactions per second in 2023 without sacrificing decentralization.
Secure, flexible, developer friendly
Smart Rollups come with state-of-the-art technical features, namely:
- Fully decentralized and open interactive fraud proofs guarantee rollup security and integrity, provided there is at least one honest participant in the rollup validation.
- A WebAssembly (WASM) execution environment allows for flexible development and deployment of a wide range of decentralized applications. Developers can now use general purpose programming languages such as Rust, C, and C++ to build applications ranging from tailor-made business solutions to public open platforms, such as an EVM-compatible chain on top of Tezos.
- Advanced rollup features simplify interactions such as broadcasting from Layer 1 to all rollups, calling Layer 1 smart contracts from Layer 2, or transferring assets across layers.
- New data availability solutions are possible, as Smart Rollups support custom data channels for interfacing with data providers external to the Tezos blockchain.
Lower latency, faster blockchain
Beyond rollups, Mumbai also introduces improvements to Tezos’ Layer 1. Block time is reduced from 30 to 15 seconds, which is made possible with so-called Pipelined validation. This change reduces network latency and provides a smoother user experience overall.
The protocol upgrade also includes updates to previously existing features, such as Tickets, which become more flexible by allowing direct transfers between users.
Evolution driven by the community
As with every Tezos upgrade, Mumbai has been validated and approved by the community through the Tezos blockchain's on-chain governance process.
The activation of Mumbai marks the culmination of a months-long collaboration between developers teams and the broader Tezos community.
Experts from Nomadic Labs, Marigold, TriliTech, Oxhead Alpha, Tarides, DaiLambda, and Functori have contributed to this update, which unveils a new era of scalability and opens the door for exciting new applications to be deployed on Tezos blockchain.

Americhem Expands Aircraft Interior Portfolio with PFAS-Free Thermoplastic Platform Meeting 55/55 OSU, Low Smoke, and Low Toxicity Requirements4.3.2026 14:00:00 EET | Press release
Americhem is expanding its aircraft interior materials portfolio with ColorFast® SFT5500, a PFAS-free high-performance thermoplastic engineered to meet FAA 14 CFR 25.853, Appendix F, Part IV, 55/55 OSU heat release requirements while delivering low smoke and low toxicity characteristics for aircraft interior applications. PFAS-free thermoplastic systems capable of achieving 55/55 OSU performance while maintaining low smoke and low toxicity characteristics remain limited in the aerospace market. ColorFast® SFT5500 addresses this need with demonstrated 55/55 OSU heat release performance, low smoke emission characteristics, and low flaming-mode toxicity performance in a high-performance thermoplastic platform designed specifically for injection-molded interior components. Aircraft interior thermoplastics must meet stringent fire standards while maintaining durability, thermal stability, and process consistency. As legacy fluorinated material systems face increasing regulatory scrutiny, ma
NETSCOUT Reveals Qualitative Shifts in DDoS Attack Sophistication, Infrastructure Capacity, and Threat Actor Capabilities4.3.2026 13:05:00 EET | Press release
NETSCOUT® SYSTEMS, INC. (NASDAQ: NTCT), today released its second half of the year 2025 Distributed Denial-of-Service (DDoS) Threat Intelligence Report, revealing sophisticated attacker collaboration, resilient botnets, and compromised IoT infrastructure that drove more than eight million DDoS attacks worldwide – some as large as 30 terabits per second (Tbps) – marking a new era of hyper-scale, coordinated threat activity that continues to outpace global takedown efforts. Meanwhile, the accelerating growth of DDoS-for-hire services is empowering a broader range of threat actors, intensifying operational risk to digitally connected organizations and enterprises. Implications for security professionals extend far beyond volumetric concerns and include reconnaissance and adaptive evasion which challenge traditional defense paradigms. Organizations must match adversarial innovation with intelligent, autonomous defenses, or risk operational disruption at levels previously considered theoret
