0/ @MetisDAO is a hyper-scalable rollup-based layer 2 solution built on Ethereum. But $METIS is not just your average optimistic rollup 🌿

A 🧵 on $METIS and why you should pay attention (0/29)👇

#L222 Image
@MetisDAO 1/ But before we dive into @MetisDAO, let’s quickly take @optimismPBC as an example to see how $METIS tackles problems that other optimistic rollups face today
@MetisDAO @optimismPBC 2/ #Optimism uses a single node called Sequencer to generate blocks on #L2. This bears speed advantages as blocks are generated in seconds because new blocks do not need to be handed over to other nodes for verification Image

0/ @OasisProtocol is a modular blockchain network that separates execution from consensus by design. Oasis supports customized ParaTimes (rollups with custom VM implementation) & aims to be a shared security layer for rollups 🌀

A 🧵 on $ROSE and why it matters (0/23) 👇 Image
@OasisProtocol 1/ @OasisProtocol is built on the @cosmos SDK, uses Tendermint BFT consensus and natively separates execution (or computation) from consensus and has a two-layered architecture:

- Consensus Layer

- ParaTime Layer Image
@OasisProtocol @cosmos 2/ Consensus Layer:

The consensus layer accepts data from its clients (the ParaTimes) & writes the data into a block of the chain. The meaning of the data generated by a ParaTime is entirely defined by that ParaTime, making ParaTimes flexible & the consensus layer VM-agnostic

0/ Polygon #Avail is a chain-agnostic, modular data availability blockchain built by @0xPolygon. Like @CelestiaOrg, it aims to provide rollups & L1s with a highly scalable DA & consensus layer ✨

A 🧵 on how #Polygon's specialized DA layer works & compares to Celestia (0/34) 👇 Image
@0xPolygon @CelestiaOrg 1/ @0xPolygon has been stealth building Avail since 2020 & has announced the testnet for Q2 2022 in April:

@0xPolygon @CelestiaOrg 2/ Unlike @CelestiaOrg, Polygon #Avail is not built on the #Cosmos SDK and not using Tendermint BFT. However, Avail is also a PoS network, using a nominated Proof of Stake consensus algorithm

0/ Rollups are a key technology in blockchain scaling, even beyond $ETH. #Cevmos for example enables the deployment of EVM rollups on top of a @EvmosOrg-based rollup leveraging @CelestiaOrg's modular data availability layer

Short 🧵 on the Cevmos stack & its purpose (0/11) ⚛️👇
@EvmosOrg @CelestiaOrg 1/ #Cevmos (short for Celestia/EVMos/CosmOS) is a modular stack for building EVM-based rollups that use #Celestia as a DA & consensus layer. The Cevmos stack will center around an optimized settlement chain for rollups, based on #Evmos
@EvmosOrg @CelestiaOrg 2/ What is Celestia?

#Celestia is a modular consensus & data availability layer built on the Cosmos SDK that aims to enable anyone to easily deploy decentralized blockchains without the overhead of bootstrapping a new consensus network

0/ One of the upcoming L1s I'm most excited about is @CelestiaOrg, a modular, chain-agnostic data availability & consensus layer that provides a highly scalable & decentralized DA solution to rollups & app-specific L1 chains✨

A mega-🧵 on why you should pay attention (0/39)👀👇
@CelestiaOrg 1/ While most blockchain ecosystems agree that the future is multi-chain, the way they envision a multi-chain world can differ heavily. Approaches that have started to gain traction over the past few months are #Ethereum (rollups), #Polkadot (parachains) & #Cosmos (zones)
@CelestiaOrg 2/ So, according to its rollup-centric roadmap, #Ethereum envisions the future to evolve around rollup-based L2 solutions. But unfortunately, rollups tend to be rather expensive to operate/use & are less flexible than L1 chains (at least pre EIP-4844 / $ETH 2.0)

0/ Data availability is the primary scaling bottleneck for $ETH-based rollup L2s and a hot topic at the frontier of blockchain scaling. But what is the data availability problem and how is it addressed?

A 🧵 about the DA problem and the current DA landscape (0/XX) Image
1/ The data availability problem refers to the question how peers in a blockchain network can be sure that all the data of a newly proposed block is available
2/ If part of the data is not available, the block might contain malicious transactions which are being hidden by the block producer
