Faster, Easier, and More Powerful

Recently, O(1) Labs announced a significant upgrade for Mina Protocol. This upgrade will make Mina much faster, easier to use, and more powerful, all while preserving its hallmark: staying tiny.

This performance upgrade will introduce three core improvements:

• Faster block creation
• Automatic upgrade system
• Enhanced zkApp capabilities

In this article, we’ll break down what each of these changes means, why they matter, and what they reveal about Mina’s future.

What is Mina Protocol and Who is O(1) Labs?

Mina Protocol is known as the world’s lightest blockchain. While most chains grow endlessly, like Ethereum or Bitcoin, Mina stays fixed at just ~22KB by using zk-SNARKs, which create small proofs verifying the full blockchain state.

Think of it like mailing a postcard of an elephant instead of the whole elephant, you get proof without the bulk.

O(1) Labs is the original developer of Mina. Since 2017, they’ve been focused on building a scalable blockchain that stays decentralized. Today, they continue leading Mina’s technical development, including this major upgrade.

What’s New in the Upgrade?

O(1) Labs’ announcement talks about a big upgrade focused on making Mina faster, more scalable, and easier for developers to build on. The upgrade has three main parts:

Faster Blocks

Mina will create new blocks much quicker — going from 180 seconds (3 minutes) per block to about 90 seconds. This basically doubles how fast the network works. This will make transactions confirm faster and the network feel more responsive, without making it less secure.

• Automatic Upgrades:
• Updating Mina’s system will become automatic. In the past, everyone running a Mina node had to manually update their software at the same time, which was complicated. Now, Mina nodes will update themselves, making future changes much smoother and more reliable.

•Stronger zkApps: Mina’s smart contracts, called zkApps (because they use zero-knowledge proofs), will be able to do more in a single transaction. The upgrade will at least double the amount of work a zkApp can do. This means developers can create more complex applications and handle more data in one go.

Besides these main points, the upgrade also includes other improvements to make Mina handle more transactions and run better. For example, each block will be able to hold more transaction data to keep up with the faster block creation. There are also behind-the-scenes improvements, like using a new version of the Mina software built in Rust (from the “OpenMina” project), which will make nodes sync faster and use less memory. All these changes together make Mina a stronger and more scalable blockchain.

Why are these changes happening now? To understand why they’re important, let’s look closer at each part of the upgrade.

Faster Blocks: Cutting Block Time in Half

Today, Mina produces a block every 180 seconds, primarily due to the time it takes to generate zk-SNARK proofs. While slower than other chains like Ethereum (~12s blocks), this ensures Mina stays verifiable and decentralized.

Now, thanks to improvements in performance and testing, the new block time will drop to ~90 seconds. That’s a 2x throughput boost, bringing:

• Faster confirmations
• More responsive zkApps
• Better real-time interaction

And yes, there are plans to go even faster down the line.

Smoother Upgrades: One-Click or Zero-Click

Upgrading Mina used to be a hassle, node operators had to manually coordinate during the Berkeley upgrade, which added zkApps.

This upgrade brings:

• Automated, seamless upgrades
• Zero downtime transitions
• Stronger network reliability

This also opens the door for faster development cycles and quicker adoption of future improvements.

zkApps Get Supercharged

This is a developer-focused leap forward.

More Account Updates per Transaction

At least 2x more account updates per zkApp transaction, enabling more powerful logic in fewer steps.

More Events & Actions

Higher limits allow zkApps to carry larger proofs, rich data, and multi-step logic.

Expanded Contract Storage

On-chain zkApp state will increase 4x, based on developer feedback. This supports use cases like DEXs, games, and identity systems with richer on-chain logic.

Mina team has said that these changes are a direct response to what builders wanted. One community developer commented, “The proposed changes to account update limits, event/action expansion, and increased app state size directly reflect feedback from builders. This feedback loop between core development and the zkApp community is exactly what will keep Mina ahead, especially as it grows into a more robust platform for complex applications.” This shows that Mina is improving based on real use and community ideas, which is a good sign for its development.

Mina in the Bigger Blockchain Picture

Vs. Ethereum and Other L1s

• Ethereum: fast, but bloated
• Mina: slower, but 22KB in size and verifiable by anyone

Mina prioritizes decentralization over TPS, and that’s a strategic choice.

Vs. Other ZK Projects

• Zcash: zk for privacy, not scalability
• zkSync: zk rollup, but not a L1
• Mina: zk-native L1 — the whole chain runs on zk-SNARKs

It could evolve into a universal ZK verification layer, interoperable with other chains.

On Speed Trade-offs

Mina won’t hit 1,000 TPS like Solana, but it doesn’t have to. Instead, it enables:

• Verifiability
• Lightweight nodes
• Modular scaling with other layers

The future is modular, and Mina is already there.

Conclusion

The upcoming performance upgrade is a big step forward for Mina Protocol. By making blocks faster, making upgrades smoother, and making zkApps much more powerful, Mina is changing from a new idea into a more practical and scalable platform. Importantly, it’s doing all this without giving up on the ideas that make it special, decentralization (everyone can participate) and privacy (through zero-knowledge proofs). As Brandon Kase, a team lead at O(1) Labs, said during a past upgrade, “the real magic happens when you look beyond just privacy or scalability… Mina is about to open up a huge new area of possibilities, and today, we take another step forward together with the community.” This feeling is still true as Mina embraces this big performance leap.

In the next few months, everyone will be watching Mina as the new changes are tested and put into action. If it works well, Mina will become stronger and easier to use, likely leading to many new applications and users. The protocol will be better able to handle everything from complex financial apps to connections with other blockchains, finding its place as the go-to network for verifiable, small blockchain applications. Meanwhile, the rest of the blockchain world will be watching to see if Mina’s lightweight approach can deliver real results on a large scale. Given the careful engineering and teamwork seen in this upgrade, there’s a lot of reason to be hopeful.

In a world often focused on bigger and faster, Mina’s upgrade shows that smaller and smarter can also be a winning strategy. As the protocol enters this new phase, Mina is set to become faster, easier to build on, and more flexible, all while staying true to its identity as the smallest blockchain with big dreams.
