What's the value of being able to verify the beacon chain consensus data? At it's most basic, if you have a light client that can track the head of the chain, you know the current state of the whole Ethereum world through the "stateroot" contained in the most recent block, which is a 64 hexadecimal string that magically assures that you can verify anything else anybody else tells you about the current state of the world (e.g. what's my wallet's ETH balance? how much USDC does Circle actually have minted, etc)

So let's start with "What is a CL lightclient"? We need to define two things. 1) CL - Consensus Layer - this refers to the part of the Ethereum tech stack also known as the Beacon Chain. It's where the validators do their job of proposing and attesting to (i.e agreeing to valid) blocks. 2) Light client - a piece of software that only validates the "consensus" data of a blockchain and not all of the execution layer logic. Clear as mud, right?

So why does anybody care about "syncing a CL light client"? Basically, it's a key part of the whole Ethereum vision, which revolves around the idea of being able to transact and interact without relying on depending on one centralized provider. Will break this down in casts to come.

Succeeded. Ever wanted to sync your own CL light client but don't want to bother with the Beacon Chain? Now, with Ultralight, you can sync one from Portal Network data.

Was going to explain SSZ but...that'll be a future thread. Today is for navigating the deep waters of trying to run Verkle blocks in a client that only sort of supports them.

So I wasn't able to really sync a light client on just Portal Network data yesterday because of one problem. SSZ types that magically change at a hard fork. More on that tomorrow

Success with some hackery. Hopefully next week we'll have active nodes tracking the of CL without actually touching the beacn chain.

I'm hoping to try and sync a Lodestar light client purely from the Portal Network today. Pair that with an EVM and what can't we do?

Time to try and make this a habit. Can I cast every day? Lessee. For now, I leave you with this. https://github.com/ethereum/js-team-organization/pull/37 The roadmap and I have a job on it. 😅

Who doesn't like a git commit as a progress report - https://github.com/ethereumjs/ethereumjs-monorepo/commit/05552af56d1601124bae7c4580e3a823242401ee

So I might be done with Zerion. Used to be a super clean, super easy to use app. For some reason the web browser is now super slow and it took me 10 minutes just to figure out where the bridge button had gone. And then the bridge option didn't even work. What other wallets should I try on Android?

Happy to report that the Paraswap team returned my funds from the whitehack draining of wallets associated with their faulty router contract. Lesson learned from this experience, revoke approvals after you're done making a swap, especially on L2. We need a smart contract wallet for this.

I guess I've finally earned another stripe on the road to being a web3 native. Have lost funds (small amount) in one previous hack but got hit by my apparent first whitehat hack in the paraswap kerfuffle this morning. Lessee if the tokens come back.

Who says you can't post blobs from the browser? https://holesky.beaconcha.in/tx/4ff708f670c32e20e43ff86d8f636b0956ed72369671b7b9272ee7d636eb077e

Are any other Protocol Guild members anxious about the Bankless guys inviting Justin Sun to make a donation to the PG as a means of atonement? Not sure how I feel about very questionable funds being active solicited for PG donations.

Who says you can't send blob transactions from the browser. Can't guarantee it will be included in a block, but progress is progress. https://sepolia.etherscan.io/tx/0x857ef5e518b7dad2ea54d910343e9f2a92f4afa371f6b6066be263b31c6f0ba6
