L2s inherited Ethereum's speed. The sequencer never made the trip. Arbitrum, Base & Optimism each run on ONE sequencer: a single node orders every transaction. That node can censor a wallet, reorder any trades, or halt the chain. Which L2 decentralises its sequencer first?

Sustainable creator economy is the future of NFT innovation. We looked for a chain with embedded royalties at the node level and didn’t find one. So we launched our own. RARI chain, Arbitrum L3 with sequencer level royalties enforcement is live on Mainnet 👇🏻

1/ From the very first day, we were promised that an #Ethereum node could run on any consumer device. In 2024, you can run on a $200 ARM64 board using ~10w: - 1 Archive node + a validator client - A Supernode (L1+L2 on the same device) This is called decentralization. +info👇

🚨The word is out! We’re bringing Chain Abstraction to CoW DAO🐮 Arcana Wallet aggregates your assets across chains and makes cross-chain swaps as easy as a single click. In the demo: 🔹Despite having no USDT on Arbitrum, Mayur | Avail swapped USDT to ETH on Arbitrum. 🔹Arcana Wallet fetched the needed liquidity from his USDT on Optimism, transferred it seamlessly to Arbitrum, and confirmed the transaction. The result? A frictionless swap experience that abstracts away chain complexities for the user. Try it yourself👉

Deploy Avail Node Without Any Coding/Commands Smoothly 24/7 Uptime You can also run a node on mobile No need for a PC or laptop. Avail Official Twitter also tweeted about this Node. Here's the guide 👇 1. Open this link on Trust Wallet or a browser: 2. Connect your wallet. 3. Go to the dashboard and buy an Avail Node; it costs around $14.99 and can be bought with any crypto. 4. Go to Active Nodes. 5. Reveal the phrase key and save it in your notes. 6. Copy the Avail public address. 7. Download the Polkadot JS Extension from 8. Import the key or create a wallet and copy the public address. 9. Go to and claim the faucet. 10. Then go to 11. Connect your Polkadot Wallet and complete all social tasks. Use the public address you copied from the Mintair | One Click Infra Node to claim the NFT. That's it! You don't need to worry about uptime; the node provider handles everything automatically.

This is the first teaser of the promised product updates we’re going to deliver for you soon. Transaction times were too slow on EOAs — and so users wouldn’t be able to take advantage of the real time transaction methods enables. Now, we’ve drastically improved the transaction processing times for both EOA wallets by implementing 7702 throughout the entire product and implementing the real time transaction API. Everytime you use GTE, your transactions will take only the time it takes to round trip between you and the sequencer. This is usually around 200ms if you’re across the world from the sequencer (which is about as fast as you blink). Now, there is no difference between using GTE and a CEX. This is what it means to be the fastest decentralized exchange in the world. You’re going to have fun trading on GTE!

How Gitbank Works Your GitHub issues just became a treasury. Sign up once at Gitbank deploys a smart contract vault on Base L2 permanently tied to your GitHub ID, not your wallet address. That ID never changes, can't be renamed, can't be spoofed. Connect your repos. Then run commands directly inside any Issue, PR, or Discussion: gitbankbot deposit 0.001 WETH. The bot executes the transaction on-chain and replies instantly with a full receipt amount, fee, tx hash, and a Basescan link to verify everything yourself. Gitbank pays all the gas. Every time. 🔗

Graph Convolutional Network by hand ✍️ ~ 12 steps walkthrough below Graph Convolutional Networks (GCNs), introduced by Thomas Kipf and Max Welling in 2017, are the tool for data shaped like a graph: social networks, recommendations, biological networks, drug discovery, molecular chemistry. I drew and calculated a simple GCN entirely by hand. Goal: run a two-layer GCN, then a small classifier, on a five-node graph, filling in every cell yourself. 1. Given A graph of five nodes, A to E, with edges between some of them. 2. Adjacency matrix (neighbors) Put a 1 wherever two nodes share an edge, in both directions. 3. Adjacency matrix (self) Add 1s down the diagonal, one self-loop per node. That is just adding the identity matrix. 4. Messages Multiply each node's embedding by the weights and biases, then ReLU. Negatives become 0. 5. Pooling Multiply the messages by the adjacency matrix. Each node gathers the messages of its neighbours and itself. 6. Visualize Node A pools [3,0,1] + [1,0,0] = [4,0,1]. 7. Second GCN layer Messages again: weights, biases, ReLU. 8. Pooling again Pool over each node and its neighbours, once more. 9. Visualize Node C pools [1,2,4] + [1,3,5] + [0,0,1] = [2,5,10]. 10. Fully connected layer Weights, biases, ReLU. This time there are no neighbours to pool, just the node itself. 11. Linear layer One more: weights and biases. 12. Sigmoid Squash each score to a probability (≥ 3 → 1, 0 → 0.5, ≤ -3 → 0). That is the classification for each node. You have just classified every node in the graph by hand. ✍️ The outputs: A: 0 (very unlikely) B: 1 (very likely) C: 1 (very likely) D: 1 (very likely) E: 0.5 (neutral) The takeaway: a GCN layer is two parts. The top part pools each node with its neighbours through the adjacency matrix. The bottom part is an MLP that transforms each node on its own. A transformer layer has the same two parts, with an attention matrix where the adjacency matrix was. Both matrices do one job, mixing across positions: attention over tokens, adjacency over nodes. In my class I call the GCN the transformer's little cousin: a bit more stubborn, because its attention is fixed by the graph rather than computed from Q, K, and V. Draw the two side by side and the resemblance is hard to miss. 💾 Save this post! #AIbyHand #GraphNeuralNetworks #DeepLearning

7 steps and 2 clues created a woman who was bought a drink by a stranger. She doesn't exist. A stranger sat at a club bar last week. She picked out a man, started a conversation, bought him a round. He smiled back. The whole scene lived in a 6-second clip that pulled comments asking who she was. She was never there. No club, no drinks, no face that belongs to anyone. Here is the full build, 7 steps end to end. Open Pinterest, search “girl selfie,” save one image. Open Nano Banana Pro and swap the face with a single prompt. That photo now belongs to no one. Move the image into a node editor. Create 3 nodes: a reference image node, a text node, a video generator node. Drop the photo into the image node. Write 1 video prompt into the text node, the line that turns a still frame into motion. Connect text to text-in, image to image-in. Select Kling 2.6, set duration, switch sound on. Hit generate. 2 prompts. One face that exists nowhere. A 6-second clip people argued was real. The next person who buys you a drink at a bar might run on a text prompt.

ComfyUI Tutorial for Beginners: Text-to-Image & Image-to-Image Workflows One graph, two workflows and Module 2 is where you build it node by node instead of loading someone else's. We start from a blank canvas and wire every connection, then change a single value and turn the same graph into image-to-image. What you'll learn: → The 5 core nodes, connected one at a time — checkpoint, CLIP encode, KSampler, empty latent, VAE decode → Why the data flows the way it does, not just where the wires go → Every KSampler setting: seed, steps, CFG, sampler, scheduler → Denoise from 0.9 to 0.0 — the one value that decides how much of your source survives → Locking seeds and generating takes instead of chasing one perfect image → Preview vs. save, and why every image carries the graph that made it → Reopen any result in your asset library as a live workflow → The 6 errors that break Comfy most often → How to read a red node like a sentence Click the links below to run the workflow ⬇️

What if you could own a piece of the world's first orbital pharmaceutical laboratory? Acme Space is not a crypto concept or a whitepaper promise, it is a real aerospace program with NASA wins under its belt, launching actual hardware into orbit for its first physical space mission, and bringing space exploration, decentralized science, and DePIN infrastructure on-chain via Base. ACME's orbital supercomputer is designed to run pharmaceutical research in microgravity, unlocking drug discovery that is physically impossible on Earth, with Ankr now live as the official infrastructure partner powering its RPC and node layer. August 17th at 1PM UTC, ACME and Ankr are hosting a major AMA, and the Phase 1 Node Sale opens August 18th at 15:00 UTC for a strict 48-hour window.
