Mimblewimble is a protocol designed to achieve various improvements like greater scalability or privacy. The founder of Litecoin, Charlie Lee, has been designing a Mimblewimble add-on block for. With a provable supply cap of 20,,, MWC is a scarce pure proof of work Mimblewimble based coin that enables greater network scalability, privacy, and fungibility than legacy blockchain protocols. All transactions on the base layer use Greg Maxwell's Coin Join with his Confidential Transactions and signature aggregation. Mar 20, · Mimblewimble is a protocol that was put forward by an anonymous user in a Bitcoin developers chatroom by the name of Tom Elvis Jedusor (the French name of fictional Harry Potter character, Voldemort). Mimblewimble itself is the name of a .

By: Pedro Febrero Email. By CCN. Key components in MimbleWimble are:. The first MimbleWimble implementation, Beam , was fully released on January 3 and is now live and minable. This means anyone can join to support the network — although in order to do so, one does require both specific hardware, in this case, a GPU processor, and some technical savviness to understand how to set up a node.
Anyhow, the oldest implementation of Milmblewimble and the one I will focus my attention on , is called Grin. The first Grin testnet was launched in November , and the project is currently live, since January The result of this are fuller block sizes which brings into question the scalability of these networks. In contrast, Mimblewimble provides inherent transactional privacy due to the removal of addresses as well as the aggregation of inputs and outputs.
In the same way that Bitcoin is a protocol and Bitcoin Core is an implementation of it, there are currently two implementations of the Mimblewimble protocol. Those include:. Grin is a cryptocurrency that was founded by an unknown individual who currently operates under the pseudonym, Ignotus Peverell another fictional character from the Harry Potter series. It embodies many of the properties of the Mimblewimble protocol described above and as such it possesses none of the following:.
When mining the Grin cryptocurrency, miners must include the following in the block header:. Grin is built in programming language, Rust ; it is a community-backed project and thus relies on donations for funding. It is headed by entrepreneur, Alexander Zaidelson, Beam released its mainnet on January 3 rd Similar to Grin, its release did not include an ICO or premine, however, Beam did secure venture capital funding.
It utilizes the proof-of-work mining algorithm, Equihash , with each block produced containing transactions, with a generation time of approximately 1 minute. In year 6, this block reward will fall to 25 BEAM, with halving occurring every four years until the year After year , there will no longer be a block reward. Beam employs a treasury model whereby in the first 5 years, 20 BEAM from the block reward will be issued to the treasury.
In the years 2 to 5, this number will fall to 10 BEAM. The purpose of this model is to repay Beam investors, incentivize the development team and fund the Beam Foundation. To promote decentralized mining on the Beam network, the protocol plans to stay ASIC resistance by performing hard forks when necessary.
As is indicated in the chart below, Beam began trading on January 17 th and experienced a sharp rise in price as well as a subsequent decline. Additional time is still needed for the respective protocols to continue to build on their projects and attract individuals to their community.
Grin does not have an official roadmap, however, there are a plethora of technologies that it could make use of in order to add further value to its network. Those technologies include:. Implementation of these technologies to the Grin network would provide an additional level of functionality as well as another value proposition to potential users. Of the two protocols, Beam has the more defined roadmap. The roadmap for the year of is as follows:.
The theoretical space savings, as well as the privacy, offered through the use of the Mimblewimble protocol is evident. By pruning the blockchain of unnecessary transaction data, scalability becomes less of an issue because more transactions can be included in a single block. Due to the obfuscation of inputs and outputs, as well as the elimination of public addresses in Mimblewimble transactions, true anonymity, as opposed to pseudonymity, is achieved.
Currently, Mimblewimble can only be integrated into the Bitcoin network as a soft fork , or as a sidechain. On this sidechain, users would be able to move bitcoins onto it and transact with an increased level of privacy.
Through the use of cryptographic innovations such as confidential transactions, CoinJoin and the cut-through feature, Mimblewimble offers a strong scaling solution, as well as an increased level of privacy. There are currently two main implementations of Mimblewimble, those being Grin and Beam. Both were launched in January of and are seeking to innovate in different ways. The first three installments were on scalability, privacy, and fungibility.
Other priorities emerged and we were not able to release part 4. After being away from the project for a while, I had some time so I decided to work on part. Groundbreaking privacy and much improved user experience is coming to MWC!
To improve the easy of use, the common user experience and further consolidate the privacy of MWC Version 4. This release includes changes from the Grin rebase. Due to a recent DNS ownership change, the request and propogation of the transfer have created a delay that affects the registration of the wallet for some users.
Because of the delay, we are extending the registration of the wallet to block , The distribution will start on block ,
