It is time to fix the crypto talent shortage. I am launching a free 8 week course on cryptocurrencies with a special focus on layer-2 protocols. Hopefully I can help the mass-exodus of web2 into web3 companies. It'll start Q1 next year - sign up today:

An interesting trend is that companies are now offering compensation (job offers) without a 12 month cliff for equity/tokens. Makes me wonder - what is the point of a cliff? Seems to benefit org over employee.

I’ve put together a deep dive on How Proof of Stake on Ethereum works. - Epochs & Slots, - Voting Protocols - Inactivity Leak, - Does it meaningfully replace PoW? - And much much more! An accumulation of 3-4 months of deep diving. Hope you enjoy it!

We made a lot of improvements to our ZK architecture, lowering our prover memory requirement from 870GB to 275GB, nearly a 68% improvement. Getting our system requirements as low as possible allows for the democratization of the decentralized prover network.

Balrog V Gandalf is the perfect depiction of rollup security. One honest party who can fend against and defeat the most powerful adversary imaginable. On behalf of everyone - you shall not pass!

Bookmarked for later! I still know so little, but that just means there's tons of room to grow:

Great explanation of mechanics of proof of stake. 10/10 would do again

Only worked on it because I thought it’d be fun and important to learn. Appreciate others helping to spread it with likes/retweets - hopefully it’ll be a nice resource to help devs/researchers/technically minded to get started. Also - do drop comments with questions!

I realised, a long time ago, even if I had the money to retire tomorrow and never work at a company again -- I'd probably still sit in a coffee shop (like I am right now) working on articles about crypto. Maybe i'd pick up piano, that'd be the only difference. lol

yo, , m8, the number 1 priority for the UK government in regards to crypto is to issue a GBP coin on Ethereum and allow us all to pay taxes to HMRC with it that will have the greatest and widest impact thx, ur fren

Removing liability is key to its success. Who is responsible for protecting the assets? - NOT the system operators for the other blockchain, - NOT the bridge operators Only 1 honest party with open-membership + a smart contract, the absolute minimal trust assumption possible.

The subtle difference is critical. Not only do rollups protect assets sent to the layer-2 chain, but it protects ALLLLLL actions performed on them! Only one honest party -- who could be you -- can contribute towards protect the integrity of all cross-chain/transferred assets.

A cross-chain bridge relies on a set of trusted validators to protect assets sent from one chain to another chain. The validating bridge - rollup - is very different. All assets, and any actions performed on them, only relies on 1 honest party + a smart contract to protect it.

If there was only a single takeaway from the past 10 years — it is the need to unlearn early lessons. The saddest outcome is becoming stuck in your thinking. No longer able to appreciate how the industry as a whole has moved forward. A willingness to learn makes crypto fun. 🥰

Thanks to a quirky path, I have spent most of my adult life happily immersed in the field of crypto. It has been remarkable, and a once in a life-time opportunity, to witness the rise of Bitcoin, Ethereum, ICOs, DeFi Summer, and all the craziness that comes with it.

This is a detailed functional Ethereum model including long-term roadmap items Flexible to easily run any scenarios/timing (eg, when 4844, danksharding, rollup data compression rates, staking rates, fees, MEV burn, issuance, etc)
