In a nutshell, roll ups are separate blockchains where all the computation is done to decongest the Ethereum Mainnet. Transactions are highly compressed before being posted on the Mainnet, in order to optimize space blocks. There are two types of roll-ups that distinguished themselves on how the information posted on L1 is verified: Optimistic Roll-ups (OR) and Zero-knowledge proof Roll-ups (ZKR). In OR, it’s pretty simple, we are... optimistic: we assume that all the transactions are correct...

Every time I help new friends diving into crypto serves as a friendly reminder on how disastrous Web3 User Experience (UX) is. « What are those 12 words? I thought everything was dematerialized and you’re telling me my entire invest rely on that scrap of paper.. » They always doubtful when I tell them it relies on high level cryptography and actually, I understand them: it’s just a paper that can be easily lost. The worst thing is that this first insight through wallet installation is just th...

Few weeks ago, Ethereum’s testnet “Kiln” merged. The community seems thrilled about the so-called Merge, but what’s “The Merge” exactly? In a nutshell, it’s just an Ethereum upgrade. Until now, miners were validating transactions by accumulating computing power to be the fastest to find the nonce of the block (Proof of Work). When the Merge occurs, no more miners but validators who put at stake 32 $ETH will be randomly selected to secure the network. (Proof of Stake) The Merge is just the nam...

Dear NFT collectors, I’m pretty sure that you own items from collections that can be spoiled. How is this possible? Shouldn’t be stored endlessly on this immutable thing we called blockchain? Not really, and let be clear on one thing about JPEG NFTs: Your image is never rarely on the blockchain, it would be way way way too expensive to upload it directly on Ethereum. In broad terms, what you own on the blockchain is just a file with your name on it and a link that points to the place where yo...

Would you trust @adam or @Simeonledoggo314159 more on Instagram ? That’s crazy how what we call an OG username - one word, no number, no underscore, 3-4-5 letters - could inspire way more confidence than any other letter combination. This halo effect encourages bunch of people to pay crazy amount of money for their name or their business name on:Web1 (website URL). fb.com was purchased 8.5m $ back in 2010. http://mostexpensivedomain.name/Web2 (social media nickname): the username @metaverse w...

Last November, my friend bought a ticket to go to Mexico for 150$. The same day, he interacted with an Ethereum smart contract and it costed him the same price. It’s on this day that I deeply understand how true was the ETH-as-digital-oil narrative.We burn oil to make moves in the physical world the same way we use ETH to do stuff in the Metaverse.Oil price and Ethereum gas fees are thorny issues we’ve been talking for months at the moment. Yet, while the oil situation seems not to have short...
