On March 29 2023 16:40:29 UTC, the Tezos blockchain successfully upgraded by activating the Mumbai proposal at block #3,268,609
This 13th Tezos protocol upgrade was jointly developed by Nomadic Labs, Marigold, TriliTech, Oxhead Alpha, Tarides, DaiLambda & Functori.
Included in Mumbai:
Smart Rollups are live on Mainnet: With Smart Rollups, anyone can deploy decentralized WebAssembly applications with dedicated computational and networking resources.
Block time reduced to 15 seconds: With improved pipelining validation fully deployed, block propagation times are significantly reduced, allowing for minimal block time to be halved to 15 seconds.
RPCs for ticket balances: Two new RPC endpoints were added to improve the visibility of ticket ownership.
all_ticket_balancesreturns a complete list of tickets owned by a given contract. And
ticket_balancereturns the given-contract’s balance of the ticket with specified ticketer, content type, and content.
New Michelson operations: Michelson opcodes
LSRwere extended to support logical operations on bytes, similar to those on nat. And an opcode was added to convert between bytes and nat values.
A peek at validity rollups: Our exploration into validity rollup (aka zk-rollup) technology, Epoxy, arrives on the Mondaynet testnet.
For more details, see the Mumbai preview post.
But Smart Rollups are much more than that. They enable entirely news way of building decentralized applications on Tezos, using any programming language that compiles to WASM, such as Rust, C/C++, Go and Python.
The scalability and flexibility makes Smart Rollups the perfect solution for any organization looking for a future-proof blockchain solution. Don’t hesitate to reach out to Nomadic Labs’ adoption and support team if you have questions regarding this.

We are excited to be part of this major step in Tezos’ evolution, and look forward to seeing Smart Rollups deployed in all varieties over the coming months!
