In the last two blogs, we looked at the pieces that make a blockchain work and how the network agrees on what is true. In here, we will look at how all those pieces sit together as layers, how blockchains are structured, and how Layer 1 and Layer 2 actually differ in practice. Once we know what each layer is responsible for, concepts like rollups, sequencers, proofs and scaling start making sense....
Decentralization sounds simple until you realise every node acts on its own. In a blockchain each node holds its own copy of the ledger and processes data independently. Nodes see transactions at different times, some go offline, some behave incorrectly and some may try to cheat. Without a way to agree the network would split into a thousand truths. Consensus is what keeps all those independent nodes and all those independent ledgers marching in the same direction....
If you’re still asking ‘Why do I even need to learn Blockchain security?’ No worries. I wrote this blog to answer exactly that. Give it a read, then come back and we’ll dive into Blockchain 101 together. Now that you are here, let’s start by understanding what is Blockchain? But wait, a bit of warning, there is way too much text in the entire blog - I tried putting some AI generated images (which make sense for the blog), but they also were not able to do much, so all the best!...
In the world of AI, I’m gonna go rebel and talk about Blockchains. Why? Because I’ve been learning and tinkering with it, and I thought it’d be fun to share. Honestly, this is as much for my own notes as it is for anyone reading. Blockchain isn’t as shiny as AI right now, but it’s still a big deal. Here’s the thing: blockchain is too important to ignore, but too risky to approach without understanding security....
