Spent some time reading up on @CelestiaOrg as a pluggable consensus and data availability layer.

🧵 Here are some of my findings and breakdowns on the Celestia design:

Current L1 scalability designs (e.g: sharding) focuses on scaling block production > block verification.

Former is useless without the latter.

Let's break down consensus vs. execution layers:

Ethereum currently uses nakamoto consensus with proof-of-work (PoW) to build new blocks. Also uses EVM to validate individual transactions.

The reliance on PoW has hindered the scalability of Ethereum as more users enter.

The anticipated change in Ethereum's consensus protocol from PoW to PoS will allow less energy requirements but will still utilise the same EVM to process transactions.

In a way, this does not fundamentally allow Ethereum to process transactions in better ways.

Celestia is a L1 blockchain that does something special with its execution layer.

Here are some properties:
- Celestia does not validate transactions
- All it does is that it takes zeros and ones in the transaction data and puts them in a block.

Current blockchain architecture combines consensus + execution layer. Smart contracts are then built on top utilising the same execution environment.

Celestia decouples consensus from execution layer. Smart contracts can choose execution environment.

How will Celestia scale?

All blockchains except for Celestia and $SOL have finite resources of an end user full node.

Bitcoin is limited to 4mb/block.

Once max cap hits, fee market emerges and fees get more exp.

Blockchain guarantees capacity, not cheap fees.

As a recap, Celestia decouples consensus and execution layer.

Anyone is allowed to post anything on chain (even invalid transactions).

Nodes will download the transactions compute state of chain locally.

Here is where data availability proofs comes to play.

It ensures coding and it will download a few random pieces that can confirm whether a transaction is valid.

This happens irrespective of how high the block is.

Celestia as a modular, pluggable consensus allows for applications and devs to choose the execution layer to build on.

This can then be plugged into Celestia for shared security.

Ultimately, the goal is for Celestia to become an important infrastructure by allowing for application specific
blockchain deployments.

A 🧵 on Mantle Network, an emerging modular L2 ecosystem. (@0xMantle)

Mantle Network is still in its Testnet phase, however, Mainnet is expected to be in Q3.

Let's take a look at its updates, governance proposals, infrastructure, etc.
1/ Infrastructure:

Mantle Network distinguishes itself with a unique three-layer modular blockchain structure.

Ethereum handles the settlement and consensus layer in this structure, EigenDA ensures data availability, and Mantle Network serves as the execution layer.
2/ Stats:

Mantle Network is in its Testnet phase; however, it has experienced significant adoption in recent months.

The network processes ~ 63.5k transactions daily, accumulating a total transaction count of 12M. Additionally, there are 897k unique wallet addresses.

There's an ongoing proposal to turn on fee switch for Uniswap.

This proposal highlights a few key pointers for how the fee switch could be carried out:

- Gradual Rollout
- Revenue Accumulation in Stables/ and or ETH
- Voluntary Staking Modules
- Risks Involved

A summary: Image
1/ What does the proposal entail?

The proposal suggests implementing a protocol fee equal to 1/5 of the pool fee across all Uniswap v3 pools and enabling the fee switch for Uniswap v2.
2/ The main objectives of the proposal is as follows:

- Introduce fees for Uniswap pools,
- Establish a system for claiming earned fees,
- And selling the fees for an asset chosen by the UNI community.

🧵 An overview of @tapioca_dao + findings:

Tapioca is building an omnichain money market utilizing LayerZero message passing.

Tapioca is introducing usd0, an omnichain stablecoin using LayerZero’s OFT standard.…
1/ Short Recap of Layer Zero:

LayerZero is a modular and highly customizable cross-chain messaging protocol that works via a Relayer and an Oracle, rather than a blockchain with an intermediate consensus layer like Polkadot’s Relay Chain.
2/ Downfall of Liquidity Mining:

Liquidity Mining was spearheaded by the launch of Compound V1.

When the liquidity mining program launched, Compound’s TVL skyrocketed over 600%.

ZK-EVMs could be the endgame for blockchain infrastructure.

Although none of the ZK-EVMs is live on mainnet, we are already starting to see interesting applications and infrastructure in the ZK-space.

Spent the holidays reading up on ZK-EVMs, here's a 🧵 on some findings: Image
1/ Back to basics..

What are ZK-Rollups?

ZK-Rollups is a L2 Ethereum scaling solution, using validity proofs to identify whether or not transactions are valid.

It works by performing computation and storage off-chain, which is later batched and posted into the main chain.
2/ Some of the advantages include:

- The ability to compress multiple transactions into one, freeing up space allowing for more scalability
- Utilises cryptography for enhanced security
- Reduces Ethereum L1's congestion issues by moving computation and state-storage off-chain
