Mimblewimble is an innovative protocol designed to enhance the privacy, scalability, and fungibility of blockchain-based cryptocurrencies. It was initially introduced in 2016 by an anonymous individual who used the pseudonym Tom Elvis Jedusor, a French variation of the name of the Harry Potter antagonist, Voldemort. The term “Mimblewimble” draws its inspiration from a tongue-tying curse featured in the Harry Potter series. In this article, we will delve into the concept of Mimblewimble and explore its inner workings.
What is Mimblewimble?
Mimblewimble is a special way of doing transactions using blockchain technology. It focuses on making transactions very private and keeping them secret. Unlike Bitcoin, it doesn’t use addresses to identify people and it keeps all transactions confidential. The technology behind Mimblewimble also makes the blockchain smaller and more efficient compared to other cryptocurrencies.
Mimblewimble was created by people who wanted to stay anonymous and they used the name Tom Elvis Jedusor, which is the French version of “Voldemort.” They believed that Mimblewimble could offer better privacy and scalability than Bitcoin.
What Are Mimblewimble’s Main Features?
What Are the Core Concepts Behind Mimblewimble?
Mimblewimble is based on two main concepts: confidential transactions and transaction aggregation.
1. Confidential Transactions
Confidential transactions are a type of cryptographic scheme that allows users to encrypt the amounts of their transactions using special keys called blinding factors. Blinding factors are random values that are chosen by the users and used to obscure the actual amounts of the transactions. However, blinding factors also serve as proofs of ownership and validity of the transactions, as they allow users to prove that they have not created or spent more coins than they own.
To illustrate how confidential transactions work, let us consider a simple example of Alice sending 10 coins to Bob. In a normal transaction, Alice would create an input of 10 coins and an output of 10 coins to Bob’s address. This transaction would be visible and traceable on the blockchain by anyone. However, in a confidential transaction, Alice would use a blinding factor to encrypt the amount of 10 coins and create a special output called a Pedersen commitment. A Pedersen commitment is a mathematical expression that hides the amount but still allows anyone to verify that the input and output amounts are equal. Alice would then send this output to Bob, along with her blinding factor.
Bob would use Alice’s blinding factor to decrypt the amount and create his own input of 10 coins. He would then use his own blinding factor to encrypt the amount and create his own output of 10 coins to his address. Bob would then send this output to the blockchain, along with his blinding factor.
The result is that anyone looking at the blockchain would only see two outputs: one from Alice and one from Bob. They would not be able to tell who sent or received how much, as the amounts are encrypted by the blinding factors. However, they would still be able to verify that no coins were created or destroyed in the process, as the sum of the inputs and outputs are equal.
2. Transaction Aggregation
Transaction aggregation is a technique that allows users to combine multiple transactions into one, reducing the size and complexity of the blockchain. Transaction aggregation is possible in Mimblewimble because there are no addresses or scripts in the transactions, only inputs and outputs. This means that transactions can be merged together without affecting their validity or security.
To illustrate how transaction aggregation works, let us consider another simple example of Alice sending 10 coins to Bob and Bob sending 5 coins to Charlie. In a normal transaction, Alice would create an input of 10 coins and an output of 10 coins to Bob’s address. Bob would then create an input of 10 coins from Alice’s output and an output of 5 coins to Charlie’s address. This would result in two separate transactions on the blockchain: one from Alice to Bob and one from Bob to Charlie.
However, in Mimblewimble, Alice and Bob can cooperate to create a single transaction that combines their inputs and outputs. Alice would create an input of 10 coins and an output of 10 coins encrypted by her blinding factor. Bob would create an input of 10 coins encrypted by Alice’s blinding factor and an output of 5 coins encrypted by his blinding factor. They would then send their inputs and outputs to each other and agree on a common blinding factor for their transaction. They would then use this common blinding factor to create another output of 5 coins encrypted by it. They would then send this final output to Charlie, along with their common blinding factor.
The result is that anyone looking at the blockchain would only see one transaction with three outputs: one from Alice, one from Bob, and one from Charlie. They would not be able to tell who sent or received how much, as the amounts are encrypted by the blinding factors. However, they would still be able to verify that no coins were created or destroyed in the process, as the sum of the inputs and outputs are equal.
How Does Mimblewimble Achieve Privacy, Scalability, and Fungibility in Transactions?
1. Keeping the amounts and identities of users hidden
Mimblewimble ensures privacy in transactions by keeping the amounts and identities of users hidden. It achieves this through confidential transactions, which prevent anyone from seeing the transferred money or who owns it. Transaction aggregation also helps by hiding the sender, receiver, and transaction history. Cut-through is another technique used to remove unnecessary details from transactions, reducing the size and complexity of the blockchain.
2. Reduces the size and complexity of transactions and the blockchain
To enhance scalability, Mimblewimble reduces the size and complexity of transactions and the blockchain. It eliminates the need for bulky addresses and scripts through confidential transactions. Transaction aggregation eliminates redundant and wasteful multiple transactions. Cut-through removes intermediate inputs and outputs that are unnecessary, improving efficiency and performance.
3. Treating all coins as equal and indistinguishable
Fungibility is achieved by treating all coins as equal and indistinguishable. Fungibility means that one unit of money can be exchanged for another of the same value without any loss or difference. Some cryptocurrencies compromise fungibility when coins become tainted or blacklisted due to illegal activities, affecting their value and usability.
4. Preventing the tracing of coin history
Mimblewimble prevents the tracing of coin history or origin through confidential transactions and transaction aggregation. This ensures that no one can identify clean or dirty coins, who owns them, or how they have been used. All coins are treated equally and fairly, enhancing fungibility and usability in the market.
What Are the Disadvantages of Mimblewimble?
Mimblewimble is not without its drawbacks and limitations. Some of the disadvantages of Mimblewimble are:
- Lack of compatibility: Mimblewimble is not compatible with existing blockchain protocols, such as Bitcoin or Ethereum.
