What Is Mina Protocol and MINA Token?

Allow us to introduce you to Mina – the protocol that has proved to be the world’s lightest blockchain powered by members. Its mission is optimizing decentralization and scalability for the blockchain.

For the reason that introduction of Bitcoin (BTC), one situation that has bothered all blockchain networks is scalability. This has affected the power use of blockchain networks, value, and the time wanted to course of transactions. Whereas a number of blockchain networks have all proffered options to the issue, all of them have confronted challenges due to their flaws. Nevertheless, Mina (MINA) protocol is altering that with its thought of succinct blockchain.

Historical past and Founders of Mina Protocol

Mina Protocol appeared again in 2017 by O(1) Labs. It had the easy objective of optimizing decentralization and scalability for the blockchain. It was initially often known as Coda Protocol however needed to change its title to Mina because of a trademark dispute with R3 for the similarity of the title to its Corda blockchain. The CEO of the corporate is Evans Shapiro, and different founding staff members embrace Izaak Meckler, Brad Cohen, Emre Tekişalp, and Vanishree Rao of O(1) Labs and Joseph Bonneau of New York College.

Mina Protocol’s Functioning

Mina Protocol’s declare to fame is the lightness of its blockchain. It even calls itself a compressed blockchain, the primary of its form. In contrast to different blockchains that require a excessive degree of computing energy to course of transactions, the bar for nodes entry into this platform is sort of low. Because of this, it attainable for anybody to attach, sync, and confirm the chain nearly immediately.

Mina’s Underlying Tech

On conventional blockchains similar to Bitcoin and Ethereum, when a node joins, it’s required to confirm all of the transactions which have occurred on the community (the complete blockchain historical past). With over 500 million transactions on Bitcoin already amounting to greater than 250 GB, it’s going to take loads of days for a daily pc to obtain and confirm the historical past. Because of this it requires particular units with a lot greater computing energy to run a full node that shops and verifies the blockchain.

Sadly, just a few individuals have the sources to accumulate this type of system. Due to this fact, most customers on Bitcoin run a light-weight node or ultralight node. It verifies solely block headers and even nothing in any respect and as an alternative depends on a trusted server. The result’s that the variety of nodes on Bitcoin is just not growing, and decentralization, one of many main functions of blockchain, is just not actually achieved whereas efficiency can also be affected.

Mina seeks to alter this by introducing a succinct blockchain. The latter is a decentralized cost system that gives a continuing verification time. That is attainable as a result of succinct proofs of state validity are added to each block. Your entire blockchain is predicated on SNARKS – micro-crypto certificates within the nodes that confirm the transactions. The entire blockchain community is simply 22KB, which is the scale of few tweets. All it takes for customers on Mina Protocol to confirm the complete transaction historical past is a zk-SNARK zero data of proof. It makes use of a Proof-of-Stake algorithm known as Ouroboros Praos.

Principal Contributors on Mina Community

There are three roles throughout the Mina Community for members to assist the seamless operation of the community. Every of those roles is correctly incentivized. They’re as follows:

Verifiers. Many customers on the community will be capable of confirm since all it takes to be a verifier and obtain full node safety is to obtain a zs-SNARK. It is just a whole lot of bytes in measurement and requires a millisecond of computational processes to confirm.Block Producers. In different blockchain protocols, this group represents the stakers or miners. On Mina Community, they get incentives within the type of community charges that the person pays and different protocol distributions similar to block rewards and coinbase transactions. People may select to delegate their stake to a block producer as an alternative of staking straight. The function of block producers is to decide on the transactions to incorporate in a block. In different phrases, they are going to most positively go for the transactions with the best charges. However block producers have one other function on Mina to keep up the succinctness of the blockchain. For each transaction added to a block, they must SNARK an equal variety of earlier transactions for his or her block to adjust to the consensus guidelines and be acceptable for different nodes.Snarkers. These are the community members accountable for producing the zk-SNARKs wanted to confirm SNARK transactions. They put up charges and name bids for his or her SNARKS, and if a block producer makes use of these SNARKs in a block, the block producer pays for them from the transaction charges they earn. Since many Snarkers are posting charges, the block producer will normally go for essentially the most cost-efficient ones, so the members compete to supply that.

Lifecycle of a Mina Transaction

A Mina transaction begins with the verifier executing the transaction, after which it enters the mempool. On the similar time, the Snarkers make proofs for the brand new transactions with out snarks. The subsequent step is when the Block producer is picked to supply a block and choose essentially the most worthwhile transactions and an equal variety of unsnarked transactions. Subsequent, the block producer should purchase SNARKS from the SNARK order e book that corresponds with these transactions.  After that, the block producer can add a brand new block to the Mina blockchain. Then, the queue state will get an replace with the addition of latest transactions and deleting the snarked transactions. The block producer then updates the zk-snark for blockchain, and the brand new block is validated.

MINA Token

The MINA token is the native cryptocurrency on the Mina protocol. It has been listed on numerous crypto exchanges similar to CoinList, OKEx, and Kraken. However the token is just not out there for individuals in United States, Canada, Australia, and Japan.

As of June 2021, the MINA token has a circulating provide of 150,013,663 tokens out of a most provide of 827,207,452 tokens.

Execs and Cons of Mina

Mina protocol gives many options to the present issues confronted by many blockchain networks, however it isn’t with out its challenges too. Allow us to have a greater data of the professionals and cons that Mina has.

Firstly, the thought behind the protocol itself is exclusive, and it solves a lot of the issues that fashionable blockchains are dealing with. Secondly, the community is light-weight and permits units with common computing energy to be full nodes. Additional, a number of top-level funds are backing the undertaking.

Nevertheless, because the protocol is open supply and isn’t patented, forks of the know-how can emerge sooner or later. Apart from, the prevailing model of the protocol doesn’t assist good contracts.


Mina protocol continues to be in its early phases, but it surely already gives potential options to scalability, excessive power consumption, and price of transactions on fashionable blockchains. It was some of the anticipated initiatives again in 2017 and has proved to be the world’s lightest blockchain powered by members.
