About
What Is Mina Protocol?
Mina Protocol is a minimal “succinct blockchain” built to curtail computational requirements in order to run DApps more efficiently. Mina has been described as the world’s lightest blockchain since its size is designed to remain constant despite growth in usage. Furthermore, it remains balanced in terms of security and decentralization. The project was rebranded from Coda Protocol to Mina in October 2020.

The Mina network has a size of only 22 KB, which is miniscule when compared to Bitcoin’s 300 GB blockchain.
What Is Mina Protocol’s Main Objective?
Mina is working on achieving an efficient distributed payment system that enables users to natively verify the platform right from the genesis block. Its technical whitepaper calls this a “succinct blockchain.”
The protocol uses Zero-Knowledge Succinct Non-Interactive Arguments of Knowledge (zk-SNARKs), a cryptographic proof that enables someone to authenticate information without revealing said information. However, enabling a user to trace the platform back to its genesis block can be impractical in a large network. As such, Mina incrementally computes SNARKS that concentrate only on the last few blocks — meaning that end-users check that zk-SNARK-compressed proof, instead of a block’s entire transaction history.
At the heart of Mina protocol is MINA, its native currency, which functions as a utility coin and medium of exchange.
How Does Mina Protocol Function?
Mina is similar to Bitcoin, apart from how it handles transactions, but also employs the account model used in Ethereum.
In this respect, the difference between Bitcoin and Ethereum is that the state of the Bitcoin blockchain contains a list of unspent coins, while Ethereum’s state is made up of account balances.
Mina, on the other hand, uses a prover (or snarker, if you will), an equivalent of a miner, to ensure each block commits to the state.
Mina employs the Ouroboros Samasika, a type of PoS mechanism specially designed for succinct decentralized networks since it provides bootstrapping from a genesis block.
Succinct blockchains contain two major functions: verify and update. Verification touches on consensus, blockchain summary and blocks, while the update function interacts with consensus and chain summary.
Apart from the above implementations, the project uses a parallel scan state to optimize transaction processing speed, which works by grouping unproven blocks and assigning the process to parallel provers.

What blockchain does Mina use? Is it its own blockchain or built on top of another?
Mina Protocol operates on its own blockchain, which is designed to be lightweight and efficient. Unlike many other blockchains that rely on heavy data storage, Mina uses zk-SNARKs (Zero-Knowledge Succinct Non-Interactive Arguments of Knowledge) to keep the blockchain size constant at around 22 KB—small enough to fit on a smartphone.
Key Features of Mina's Blockchain:
- Standalone Blockchain – Mina is not built on top of another blockchain (like Ethereum or Solana). It has its own consensus mechanism, native token (MINA), and decentralized network.
- zk-SNARKs for Scalability – Mina uses zk-SNARKs to compress the blockchain into a tiny, verifiable snapshot, making it highly scalable and accessible.
- Proof-of-Stake (PoS) Consensus – Mina employs a PoS mechanism called "Ouroboros Samisika" (a variant of Cardano’s Ouroboros) to secure the network.
- Smart Contracts & SnarkyJS – Mina supports smart contracts through SnarkyJS, a JavaScript library for writing zk-SNARK-based applications.
Comparison to Other Blockchains:
- Not a Layer 2 – Unlike zk-Rollups (e.g., StarkNet, zkSync), Mina is a Layer 1 blockchain with its own ledger.
- Not Forked from Another Chain – Mina was built from scratch with a focus on minimalism and zk-SNARKs.
Use Cases:
- Privacy & Verification – Mina’s zk-SNARKs enable private transactions and efficient verification.
- Decentralized Identity & Apps – The lightweight nature makes it suitable for mobile and IoT applications.
In summary, Mina is an independent blockchain with a unique architecture optimized for minimalism and scalability.
Is Mina programmable? Does it support smart contracts or decentralized applications?
Mina Protocol is a lightweight blockchain designed for efficiency, with a constant-sized blockchain (around 22 KB) that makes it highly scalable. However, its programmability and smart contract capabilities are more limited compared to platforms like Ethereum or Solana.
Programmability & Smart Contracts in Mina
Smart Contracts (Limited Support)
- Mina does not natively support Turing-complete smart contracts like Ethereum's Solidity or Solana's Rust-based programs.
- Instead, it relies on SnarkyJS, a JavaScript library for writing zk-SNARK-based programs (zero-knowledge proofs).
- These programs are not traditional smart contracts but rather zkApps (Zero-Knowledge Applications), which use zk-SNARKs for privacy and verification.
zkApps (Zero-Knowledge Applications)
- zkApps are Mina's equivalent of smart contracts, but they focus on privacy and verification rather than general computation.
- They allow developers to create decentralized applications (dApps) with private transactions and efficient proofs.
- Example use cases: private payments, identity verification, and confidential voting systems.
Programming Language & Tools
- Mina uses SnarkyJS (JavaScript/TypeScript) for writing zkApps.
- Developers can also use O1JS, a Rust-based language for zk-SNARK development.
- Mina’s zkApp CLI helps deploy and interact with zkApps.
Comparison to Other Blockchains
| Feature | Mina (zkApps) | Ethereum (Solidity) | Solana (Rust) |
|---|---|---|---|
| Smart Contracts | zk-SNARK-based (zkApps) | Turing-complete (Solidity) | Turing-complete (Rust) |
| Privacy | Built-in (zk-SNARKs) | Limited (via ZKPs) | Limited (via ZKPs) |
| Scalability | High (22 KB blockchain) | Moderate (Layer 2 needed) | High (fast finality) |
| Programming Language | JavaScript (SnarkyJS), Rust (O1JS) | Solidity, Vyper | Rust, C |
Conclusion
Mina is programmable but in a different way than traditional smart contract platforms. It focuses on zk-SNARK-based applications (zkApps) rather than general-purpose smart contracts. If you need privacy-preserving dApps, Mina is a strong choice, but for general computation, Ethereum or Solana may be more suitable.

How fast are Mina transactions? What is the typical confirmation time and throughput (transactions per second)?
Mina Protocol is designed to be a lightweight blockchain with a focus on efficiency and scalability. Here’s a breakdown of its transaction speed, confirmation time, and throughput:
1. Transaction Speed & Confirmation Time
- Block Time: Mina produces a new block approximately every 30 seconds.
- Finality: Transactions are typically considered finalized within 1-2 minutes (about 2-4 blocks), depending on network conditions and consensus mechanisms.
2. Throughput (Transactions Per Second - TPS)
- Mina’s theoretical maximum throughput is around 20-30 TPS under optimal conditions.
- In practice, real-world throughput may vary based on network congestion, transaction complexity, and consensus participation.
3. Key Factors Affecting Performance
- Lightweight Design: Mina’s 22 KB blockchain (due to zk-SNARKs) allows for faster synchronization and lower computational overhead.
- Consensus Mechanism: Mina uses Ouroboros Samisika (a variant of Ouroboros), which balances speed and security.
- Transaction Complexity: Simple transactions (e.g., transfers) are faster than smart contract executions.
Comparison to Other Blockchains
| Blockchain | Avg. Block Time | TPS (Theoretical) | Finality Time |
|---|---|---|---|
| Mina | ~30 sec | 20-30 TPS | 1-2 min |
| Ethereum | ~12 sec (post-Merge) | ~15-30 TPS | ~12 sec (finality varies) |
| Solana | ~400-500 ms | ~2,000-65,000 TPS | ~1-2 sec |
| Cardano | ~20 sec | ~250-1,000 TPS (with Hydra) | ~20 sec |
Conclusion
Mina offers moderate speed with fast finality (~1-2 min) and decent throughput (20-30 TPS). Its lightweight design makes it efficient for mobile and low-resource devices, though it may not compete with high-throughput chains like Solana. For most use cases, Mina provides a good balance between speed and security.

How much data can I store on the Mina blockchain? Does it support on-chain data storage?
The Mina Protocol is a lightweight blockchain designed for efficiency, with a fixed size of around 22 KB for the entire blockchain at any time. This is achieved through recursive zk-SNARKs (Zero-Knowledge Succinct Non-Interactive Arguments of Knowledge), which allow the blockchain to compress its history into a small, verifiable snapshot.
On-Chain Data Storage in Mina
Mina does not support traditional on-chain data storage like Ethereum or Solana. Instead, it focuses on verifying data off-chain using zk-SNARKs. Here’s how data storage works in Mina:
No Direct Data Storage
- Mina does not store arbitrary data (e.g., files, large datasets) on-chain.
- The blockchain itself remains minimal (~22 KB) to ensure scalability.
zk-SNARKs for Verification
- Data is processed and verified off-chain, and only a small proof (zk-SNARK) is stored on-chain.
- This allows Mina to verify large datasets without bloating the blockchain.
Smart Contracts (SnarkyJS)
- Mina supports SnarkyJS, a framework for writing zk-SNARK-based smart contracts.
- Developers can use zk-SNARKs to prove computations off-chain and submit proofs to Mina.
Potential Workarounds
- If you need to store data, you can:
- Use IPFS or Arweave for decentralized storage and anchor proofs to Mina.
- Store only hashes or commitments to data on-chain.
- If you need to store data, you can:
Comparison with Other Blockchains
| Blockchain | On-Chain Storage | Storage Mechanism |
|---|---|---|
| Mina | No (only proofs) | zk-SNARKs (~22 KB) |
| Ethereum | Yes (gas-dependent) | Smart contracts, EVM storage |
| Solana | Yes (high capacity) | Account-based storage |
| Filecoin/IPFS | Yes (decentralized) | Off-chain storage with on-chain pointers |
Conclusion
Mina is not designed for on-chain data storage but excels at verifying data efficiently using zk-SNARKs. If you need to store data, consider using off-chain solutions (like IPFS) and anchor proofs to Mina.
