Zero knowledge proofs (ZKPs) will revolutionize how we think about privacy and scaling computation. And they're just starting to take off. Don't want to get left behind? Here's a quick primer, just for you👇

Luozhu 📜 @LuozhuZhang

The next big goal of Ethereum after the merge is sharding (Danksharding) And because merge and sharding (including other upgrades of Ethereum) work in parallel, sharding has made a lot of progress

Some thoughts on Layer 3👇

polynya @apolynya

On the confusion of L3, L4, validiums etc; I had posted this in July 2021 as a fun experiment So, an L3 rollup with on-chain data can be: L321 L3 validium can be L323, or 322 or whatever; L2 volition L32N as appropriate No one should call it these, this is just for fun

pseudotheos @pseudotheos

With 4844 and Danksharding on the horizon, the focus needs to shift towards building novel applications to keep blockspace valuable.

In July @Scroll_ZKP released the Pre-alpha-testnet version. It's worth noting that Scroll already supports proof generation. And last month we showed how to deploy smart contracts on Scroll live at SBC. Soon it will be available to everyone. So how Scroll rollup works?🧵
