First of all, it is worth saying that Mina Protocol is a decentralized platform that has the lightest blockchain in the world: its size is 22 KB. Thanks to this, many problems are solved, such as: network congestion, ease of use and integration into traditional services, data privacy. Miners also have access to fast synchronization with the network and transaction verification without the need to have resource-intensive equipment.
Why does Mina have such an easy blockchain?
The technology that allows you to use the protocol is called zero-knowledge proof. This means tiny cryptographic certificates that check the state of the network, while not disclosing the internals of the chain.

zk-SNARKs
For a better understanding, we use a metaphor: imagine a geologist who found several huge boulders (blocks) in the forest. He checks their marble drawing (checks the transaction), opens them and tells his colleagues (other validators) about his find. Colleagues also want to study the boulders, but for them a trip (the price of launching a full-fledged testing node) to this forest is too expensive. A geologist comes up with a brilliant idea: to photograph boulders (a photo is just a zero – disclosure proof, or zk-SNARKs – Zero Knowledge Successful Non-Interactive Arguments of Knowledge). As a result, there is no need for the boulders themselves, since there are photos. In Mina, blocks are discarded after their verification and replaced with snapshots of each block. The snapshot chain can thus be considered a strong improvement relative to the block chain. However, one problem is still not solved: the chain will grow in any case, and it is desirable that it be constant. But our geologist also solved this problem: he photographs the first boulder, and then photographs the second boulder along with the photo of the previous boulder. So, the first photo is no longer needed. The geologist continues to take photos using this technology and sends the last picture to his colleagues. zk-SNARKs are something similar to two-dimensional photos of 3D objects.
To be more precise, zk-SNARKs are tiny cryptographic proofs of something much larger. The block goes in conjunction with its own image, after which the images are attached to the photo of the entire chain. So, Mina shrinks the chain to 22 KB.
How does the Mina Protocol work?
To understand the structure of transactions in Mina, we will consider the mechanism of their functioning using an example.
- First of all, the user Nick sends a signed transaction to the network. Validators start processing it.
- Block producers select a transaction and include it in the list of tasks. In parallel, the manufacturer's node is selected, which will take SNARK photos.
- The block producer attaches the SNARK to the transaction. He purchases the evidence on the Snarketplace. Among these proofs is a confirmation for Nick's transaction.
- The manufacturer supplements the block with confirmed transactions, after which it enters it into the blockchain. Next, a new set of tasks is formed and the SNARK and the state of the block chain are updated. In other words, the block is confirmed.
- Nick checks that the transaction has been completed. The confidence in this grows as the number of added blocks increases. The payment is considered completed when at least three blocks have been confirmed.
What is zk-Snarks?
Validators check new blocks before adding them to the blockchain. In many networks, all miners and validators carry out verification, which is why the volume of the blockchain is growing many times. In the platform under consideration, the validator "photographs" each block and shows the picture to the other participants. That is why there is no need to display all transactions. These pictures are called Snarks or zk-SNARKs.
Projects and prospects
Mina Protocol is owned by the Mina Foundation, which plans to develop recursive SNARK applications together with the Ethereum Foundation. The applications will potentially be embedded in the Ethereum virtual machine.
In addition, the platform developers want to create a decentralized Snapp application based on the SNARK proof.
Thanks to this, the blockchain will interact confidentially with the Internet. The bottom line is that according to the plans, Snapp will validate and share with external applications not the data itself, but their proofs. As an example of use, we can name inclusive web oracles. They take data from the Internet (for example, cryptocurrency quotes, game results) and translate it into a language that is understandable to the blockchain. This will make it possible to create decentralized markets. The ChainLink platform has already demonstrated such capabilities. It is worth noting that the oracle of the solution requires an agreement to connect to the widely available HTTPS protocol.
The revolution in decentralized Protocols
- Thanks to the fixed-size blockchain, Mina has an unprecedented resistance to censorship, thereby creating the corresponding money.
- zk-SNARKs provide applications to the platform that calculate logic and information outside the network to form confidentiality and scalability, after which it is checked for integrity in the network.
- Developers have easy access to electronic dollars using the Mina protocol. Any user can enter payments via stablecoins into their applications only through a couple of lines of code.
Let's look at each statement in more detail
- Censorship-resistant money. Each user of the minimal blockchain can check the status of the registry with the guarantee that there will be no resistance to censorship. Mina is the first censorship-resistant medium of exchange for everyday use.
- A new generation of applications. Calculations using the Ethereum scheme led to several problems: high transaction fees, network congestion, unprotected user data, and ever-increasing prices for computing the entire chain, if the developer decided to deploy the application. These problems are solved in Mina thanks to a new kind of decentralized Snapps applications. These applications are distinguished by such characteristics as: scalability (applications check the fact of calculation execution, allowing processor calculations to move outside the chain); confidentiality (all information is not disclosed when checking its integrity).
- Digital dollars available to everyone. The platform easily introduces stablecoins into standard web and mobile applications. A couple of lines of JavaScript code allow developers to instantly integrate digital dollars into products. It is JavaScript that is planned to be supported as a development language for Snapps.
What opportunities does this combination of characteristics provide?
- Making payments through standard web applications without control.
- The ability to show that the user's credit rating and salary are sufficient to obtain a loan. The income itself and the payment history in this case are not disclosed.
- The ability to make sure that the snapshot is authentic.
- Anonymous voting: no one will see who the user voted for, while everyone can find out the results.
- Transmitting user identification data to only one authentication provider, which does not require trust.
Snapps will allow young entrepreneurs anywhere in the world to create crypto assets that are directly introduced into traditional finance without additional costs, difficulties and the need to ask for permission from supervisors.
According to the plan, Mina will support a bridge to Ethereum and easily convert DApps to snapps.
Mina's vision for the future of decentralized technologies is that all DeFi platforms, open financial platforms and decentralized exchanges operate on the basis of Mina with high bandwidth, low developer and user costs, and data privacy.
The MINA cryptocurrency is the key currency of the platform in which calculations are made. Currency holders are needed for the production of blocks and staking. The purchase of evidence in the Snarketplace is also made in MINA. Any user can start a node for staking or delegate the currency to validators.
The peculiarity of MINA is that it is subject to inflation, in other words, its supply has no boundaries. The initial launch of the main network is accompanied by the distribution of up to 1 billion MINA, which are blocked for 8 years. Blocking is rewarded with 12% per annum in the first years, then the percentage is reduced to 7% for 4 years.

MINA cost
The launch of MINA on the exchange took place on April 15. The currency began to be sold at 9.7 USD. Since that moment, the MINA rate has already taken off more than 15 times, until it reached the highest price. And then the adjustment began. At the end of June 2021, the exchange rate was approximately 1.44 USD.

The future of Mina Protocol
Thanks to the protocol, it will be possible to create efficient and secure Snapps, unlike other blockchains that sacrifice security in favor of high throughput and scalability. The prospects for the protocol are also good because the validators will not need to process a lot of data, respectively, it will be faster to reach a consensus. There is a possibility that Mina Protocol will grow into an ecosystem in which, in addition to decentralized projects, there will also be information providers from the Internet (providers of quotes, event results, news agencies, and others). Such changes will be the starting point for an incredible growth, which is likely to have a positive impact on the MINA rate.
Answers to popular questions about the Mina Protocol token
1. When should I expect to enter the stock exchanges? The MINA cryptocurrency can already be bought on exchanges. To purchase, you need to create an account, put funds there and exchange assets for MINA.
2. How do I get MINA? Today, you can buy a token on any exchange where the coin is traded. On the CoinMarketCap website, you can find a list of exchanges on which Mina Protocol is traded. More detailed steps for buying currency are as follows:
- Register on the exchange and confirm the registration via email. Some exchanges will require verification (KYC). You should protect your account with two-factor authentication (2FA) and other security methods in order to avoid theft of funds from your account and phishing.
- Deposit funds to the account. For this, fiat currencies and USDT stablecoins are suitable, the latter are often traded in pairs with cryptocurrencies. You can buy stablecoins for rubles or other currency in the Trustee Wallet, where you can also store digital assets.
- Purchase currency. The fastest way to buy is with the help of market orders.
- Withdraw funds back to the wallet. At the moment, only validator nodes take part in staking, for which you need to be an experienced user. However, the developers will soon add a delegation mechanism. Cryptocurrency can be frozen to get more coins, but it will not be possible to withdraw them for 8 years.
3. How can I participate in the Mina Protocol? The user can trade the SNARK proof or become a validator on the network and lock up MINA.
4. What price will the cryptocurrency have? As with any asset, the exchange rate changes and depends on demand. As a rule, if there is an increasing trend in the cryptocurrency market, many altcoins and tokens begin to grow in price. This is especially true for those who have value for the community. Of course, there are periods of correction when the exchange rate begins to fall. That is why it is impossible to accurately predict the future of cryptocurrency.

5. Where to start? As already mentioned, launching your own node is available only to advanced users. However, you can steak on the platform, for which you need to do the following:
- Buy MINA on any available exchange.
- Create a wallet for storing currency.
- Withdraw coins to your wallet. To do this, there is no need to launch your own node, it is enough to delegate coins to another validator and receive rewards.
- Staking coins in your wallet. For a more detailed description of the delegation of MINA, you can refer to the guides on the Internet. It is important to remember that the user must pay commissions, so it is worth laying a few coins for this. Without this, it will not be possible to perform operations in the wallet. The user will have to additionally top up the wallet.
So, in this article, we have analyzed the Mina Protocol project with a compressed blockchain. We looked at how the platform works, what zk-SNARKs are and why they are, how to buy the MINA cryptocurrency and the stages of working with the platform, talked about the future of the Mina Protocol and how developers strive for this future.
