This is my current attempt at explaining the overall concept(s) and core elements of zkEVM - as simply as possible. No simple task as I am sure you are all aware!
(Infographic as of July 2023)
It is certainly a challenge to convey zkEVM with minimal words while also including all relevant elements (and hopefully still be understood by those who have only a beginner level understanding of the basics of Ethereum itself). But I hope this adds some level of insight.
On Taiko zkEVM & Type:
While zkEVM is really the holy grail for layer 2 - Taiko is building a Type-1 zkEVM, 1-1 with EVM (ie a true Ethereum-equivalent solution) - the most ‘pure’/powerful kind of zkEVM. Layer1 smart contracts can be reused/redeployed without any need for changes - Taiko zkEVM works with any previous Ethereum EVM system code. This is also the ideal zkEVM to work together with rollups!

On Loopring as a L3:
A test Layer 3 Loopring was just deployed to Taiko Alpha-3 Testnet, which means Loopring is getting cozy with zkEVM currently as well. We could see this make Loopring even more efficient as a Layer 3, while opening up the potential to interface with Taiko’s zkEVM in the future (*although please note plans for this are not yet known or announced)
I was glad to see such a positive response to the reddit post I made about this infographic last week + feedback on twitter. I know there are a lot of people who want to understand zkEVM and Taiko better, so I hope I can help demystify relevant ideas & drive discussion with content like this.
I am always open to any feedback or suggestions (I can make edits/updates to this infographic if anyone spots something which can be explained better). I am also interested in doing more deep-dives on various areas of Taiko/zkEVM like this in the coming months. ie EMV Bytecode & ‘Circuits’ are two topics in my sights right now. If you have any other Taiko-related topics you would like to know more about, definitely mention here in the comments - lets help spread that zkEVM knowledge!
Footnote/Shameless self promotion:
I’ve been getting into Loopring/Taiko/zkEVM dev for over a year now and enjoy trying to explain and learn about these topics, sharing that knowledge where possible. I post dev/projects/ramblings mostly over on twitter for those interested in following along!
