What Is Mimblewimble?

Mimblewimble is a blockchain protocol that allows for a completely private transaction platform through a unique security framework that is markedly different from that of the pseudonymous Bitcoin cryptocurrency. In Mimblewimble, there are no addresses and transactions are fully confidential. Its distributed ledger is also relatively more compact than the other chains in the crypto space.Fittingly, Mimblewimble was developed by anonymous users who went by the name Tom Elvis Jedusor, which is a French counterpart for “Voldemort.” According to Jedusor, Mimblewimble is designed to affect greater privacy and scalability than Bitcoin.

How does Mimblewimble work?

Mimblewimble’s transaction structure is derived from “confidential transactions,” which were first discussed by Blockstream’s Dr. Adam Back, incidentally also a Satoshi Nakamoto frontrunner. This method is also used in other privacy coins like Monero.To elaborate, it all begins with a private transaction where the amount of a given token a sender wants to process is encrypted by way of “blinding factors.” Blinding factors refer to random values chosen by a sender which a receiver has to choose from. If the receiver selects a similar value, then the transaction is deemed valid.

In Mimblewimble, blinding factors have to be chosen by a sender. This way, it functions like a proof of ownership for the receiver, authorizing them to use the coins.

MimbleWimble vs Bitcoin

Several features make MimbleWimble stand out from Bitcoin. First, it has a much smaller blockchain size. MimbleWimble transactions are more efficient than Bitcoin ones, so the blockchain doesn’t need to store as much data. This makes it faster and more scalable.

Second, MimbleWimble is more secure. It uses a different hashing algorithm called elliptic curve cryptography (ECC), which is more difficult to break than the hashing algorithm used in Bitcoin.

Finally, MimbleWimble offers privacy features that Bitcoin does not provide. All transaction data is hidden, so people can’t see what you are spending your money on. This could make it appealing for criminals or people who want to keep their financial transactions private.

Despite these advantages, there are some potential drawbacks to MimbleWimble. For example, it’s not as well-known as Bitcoin, so it might be less likely to be adopted by merchants and users. Additionally, because all transaction data is hidden, it could be difficult to track down criminals who use MimbleWimble for illegal activities.

Overall, MimbleWimble is a promising cryptocurrency that offers several advantages over Bitcoin. With its smaller blockchain size, faster speed, and enhanced security, it could become a major player in the digital currency world.

Pros and Cons

Mimblewimble has both advantages and disadvantages. Some of the advantages include privacy, scalability, and fungibility. The privacy aspect is that it is difficult to track transactions on the blockchain as they are hidden within the confidential transaction. Scalability is another advantage as Mimblewimble can handle many transactions per second. Fungibility is an important feature for digital currencies as it means that all coins are equal and interchangeable. This is important as it prevents someone from blacklisting certain coins.

Some of the disadvantages of Mimblewimble include the fact that it is still in development and has not been implemented yet. There is also a lack of understanding of how it works, making it difficult to adopt by people and businesses.

Mimblewimble is still in development, so it is too early to say whether the advantages outweigh the disadvantages. However, its features such as privacy, scalability, and fungibility are important and could make a big difference in the digital currency space. It will be interesting to see how Mimblewimble develops and whether it can live up to its potential.


Mimblewimble is a new cryptocurrency protocol that offers a number of advantages over traditional blockchains, including increased privacy and security, fast transactions, and low fees. While it is still in development, there is no doubt that this technology has the potential to change the way we use cryptocurrencies.
