Ouroboros "short" Leios Protoyping simulation & visualisation work in progress demonstrated by Duncan Coutts. Full P2P network running Leios Visualisation. You can see 100 different nodes and messages flowing between them all, with representation of Input Blocks (Top left, Endorsement Blocks (20 seconds In these increment), Votes (20 seconds... in these increment as the pipeline hits a vote stage) You can see the votes continue to burst at roughly 20 seconds, input blocks also increase, the smoothness of message flows to reduce these bursts is something Duncan details they are working on to improve as-well as resource usage. Input Blocks (IB) - These blocks contain the raw transaction data submitted by users to the blockchain. Endorsement Blocks (EB) - These blocks reference multiple Input Blocks and are used by nodes to validate and vote on the readiness of transactions for inclusion in the blockchain. Votes- Nodes cast votes to achieve consensus on the state of the ledger, enhancing the speed of transaction finality. I believe this is completely off-chain so does not incur transaction costs (Someone keep me honest please) Keep an eye on the diffusion latency chart, as Duncan mentions this is very important, this refers more to time taken for propagation of information across the network I believe. This was an extract from a larger demonstration, really exciting, massive credit to the team working on this. It's going to be extremely impactful to Cardano and I will share as much as I can about it, I really like seeing these visualisations especially during a prototyping stage. What I find interesting is that the visualisation vote count is so much it slows down the browser rendering. Great work! web3innovationnerds & Duncan Coutts what a demonstration that was., keep them coming!show more

Voting consensus offchain really excites me. Look at how bad Solana is architectured from this perspective, most of their blocks are full of voting transactions. To be a validator you need to spend thousands of dollars to vote for consensus, also that's excluding hardware requirement cost to run the validator which is significant. Their blocks contain vote transactions which directly limits their throughput. Leios to the rescue.

A nice graphic here to represent the TX, with a Input Block & Endorsement Block, vote flow.

@ItsDave_ADA Watching the Ouroboros 'short' Leios prototyping is like witnessing a digital ballet, where every node pirouettes with purpose and precision. Duncan Coutts must be the choreographer of this blockchain masterpiece, ensuring every message flows seamlessly.

Looks awesome! As a non technical person, is there a current best guess on what this translates to in terms of transaction finality time (both assumed finality and final settlement time), and how about total throughput in tps? You are a legend in this space Dave!

:) appreciate the kind words. No idea as the prototype is a work in progress but the results I am seeing are great. I'm expecting significant throughput increase.

Zcash engineer Evan Forbes explains how they're working to overcome a fundamental limitation of proof of work to enable much faster blocks and higher throughput “One of the fundamental problems with proof of work comes from its superpower. Proof of work is permissionless. It's censorship resistant and that means that anyone can produce a block” “As you produce a block, it can happen that someone else produced a block at the same exact time and this is problematic because now you lose money effectively” “It's basically the fundamental problem of two people producing blocks at the same time. This is the bound on making things lower” “There's different approaches. You have this DAG approach where we simply let all blocks contribute to the chain or most blocks” “There's a separate approach that we're working on now which is similar to autobond, which is another thing from proof of stake that we're sort of adapting for proof of work” “Both of these things allow us to make the blocks much, much, much faster and much, much higher throughput”

How Cardano's Leios upgrade turns one block every 20 seconds into 65x the throughput Today every transaction waits on a single block every 20 seconds. Leios adds two layers beneath it. Input blocks bundle transactions every 0.2 to 2 seconds, and endorser blocks validate them in parallel every 5 seconds. The 20-second ranking block still anchors final order, so Praos security carries over intact. Cardano Community's Musashi Dojo testnet is live now, with the mainnet fork targeted for November. $ADA

Seattle Seahawks HC Mike Macdonald - Pressure vs Duo Scheme - "I want to take blocks they're going to have and I want to move them. So the guys that are getting single blocks, I want to wipe those blocks. A lot of times I'm moving into the Duo, so I can wipe the Center's block and Edge pressure away from where the TE is. Or I want to create space in the C gap and I can try to penetrate it there." - "But any time we're looking at early down run pressures, it's all about the blocks you're going to get & how you can move/manipulate those blocks to try & get someone running free or attack those run schemes."

Andrej Karpathy on autoresearch with an untrusted pool of workers: "My designs that incorporate an untrusted pool of workers (into autoresearch) actually look a little bit like a blockchain. Instead of blocks, you have commits, and these commits can build on each other and contain changes to the code as you're improving it. The proof of work is basically doing tons of experimentation to find the commits that work." The idea that distributed & permissionless autoresearch ~= proof-of-useful-work remains a high-level intuition for now, but it is extremely intriguing to say the least. Someone needs to take this further. See QT for more on what's missing.

We are excited to announce that the latest tests related to the Mazze Devnet have been a resounding success. In this post, we have attached a video demo showcasing the seamless process of running a node on the Mazze Devnet. You will see interactions with both the DAG address and the EVM address, but most importantly, you will witness the impressive speed capabilities of Mazze. In these tests, the chain achieved over 30 BPS (blocks per second), operating with just 2 nodes. Due to the nature of the EVM, each block can include approximately 1,500 simple transfer transactions, resulting in a total capacity exceeding 45,000 TPS (transactions per second). It is important to note that these tests are designed to demonstrate the blockchain's capabilities. Achieving such a high number of blocks per second requires adjustments to mining reward parameters to prevent excessive inflation. Also, the number of blocks generated per second must be tailored to the network's needs. Most importantly, this breakthrough opens new horizons and possibilities. The current structure of the chain, with the EVM layer running above a DAG layer, paves the way for future projects to develop Layer 2 solutions on top of Mazze, benefiting from the exceptional speed of our blockchain. We are confident that this is just the beginning. The results from these tests underscore our commitment to innovation and performance. We believe that Mazze is poised to become a leading platform in the blockchain industry, offering unparalleled speed and scalability. Stay tuned for more updates as we continue to push the boundaries of what is possible with Mazze. Thank you for your continued support. Together, we are building the future of blockchain technology.

Let's address the DDoS concern regarding Cardano's Linear Leios upgrade. There is a concern that if the network is forced to discard endorsement blocks, it could waste SPO resources and act as a denial of service vector. It’s a valid point, but the architecture accounts for this. When a block is dropped, the actual transaction validation work isn't lost, it simply carries over to the next one. Watch the short clip below for our full thoughts on this 👇

Introducing A tool that allows you compute anything. Think of how programming languages work. You are not restricted to a certain type of program rather you are given the building blocks to build whatever you want. That's the goal for A turing-complete math platform that gives you the building blocks to calculate, experiment and build deep computational flows. This is the first of many demos. Try it out and join me on this journey as I build the best math and computation platform.

Last night I built and deployed a live visualisation of Cardano. It now shows SPO block production in real time. You can SPO's minting blocks as they happen, with an approximate geographic view, current live stake, pool logo, mission description and search, stake amount and more. I will extend it as and when I get more time. No one is funding this. It is built in my own time, and funded by myself, because I wanted to showcase Cardano and it's SPO's visually in how they run a global decentralized blockchain from all corners of the world, whilst allowing users more visibility over researching SPO's. If you find it useful and want to support the work, you are welcome to delegate to DAVE stake pool. Cardano is global, hope you like it. 💙

How does voting on amendments work? Note: Video attached, links to the video and sources on all platforms in the second tweet. I would appreciate you subscribing to me on YouTube and TikTok as well. In the decentralised world of the XRP Ledger, there isn’t a single entity or authority dictating the rules or making unilateral decisions. Instead, the ledger relies on a process involving a select group, known as the Unique Node List (UNL) validators, to navigate its course, particularly when making changes or updates, known as "amendments". Amendments for the XRPL are proposed alterations to functionality and can encompass various aspects, such as introducing new features, enhancing existing functionalities, or rectifying issues. While the network is open to everyone, the 35 UNL validators hold the voting power to decide whether these proposed amendments get a green light. The network independently tallies these votes and determines if an amendment has garnered enough "yes" votes to be instituted as a new rule. If an amendment secures a "yes" from enough nodes for a continuous two-week period, it becomes activated, making the introduced change or feature available. The threshold is 80% of all eligible nodes. An intriguing aspect of this process lies in the evolution of rippled itself. In earlier software versions, servers would automatically vote "yes" to any amendments they understood unless configured otherwise by their operators. However, in more recent versions, such as 1.9.2 and newer, the default to voting was changed to "no" for new features, except for changes to fix bugs. Regardless of whether the default vote is "yes" or "no", it’s imperative for the operators, those who manage the servers, to assess the impact of amendments diligently. They ought to decide their vote based on their best judgement and the criteria they deem significant. This information is pivotal in sharing insights on amendments and elucidating how validators should cast their votes. When a rule has been in place for two years, it can be "retired". This means it becomes a standard part of how things work and isn’t considered an amendment anymore. It's like the rule becomes so normal that it's just a regular part of the game. If you are curious to see how validators vote and the progress of certain amendments is, you can check the visualisation on xrpscan. Please remember that UNL nodes can be added or dropped at any time, which means the number of nodes can change. The threshold in percent remains the same. In simpler terms, the XRPL employs a democratic approach to implement changes, albeit with voting power concentrated in the hands of the 35 UNL validators. Amendments, or proposed changes, need a substantial amount of "yes" votes, from 80% of all eligible nodes, to become a permanent part of the ledger’s operation. It’s crucial for server operators to thoughtfully consider how they vote on amendments, ensuring the network remains secure and operates effectively for all participants. The unwavering commitment of UNL node operators is sole to the XRPL, irrespective of the preferences or wishes of any particular party. All participants tirelessly endeavour to ensure the ledger remains secure and operational at all times. NOTE: As voting is a hot topic, I quoted the AMM Tweet, allowing you to see the process in action.

I made this tool 4 years ago for helping with customer support emails. Instead of typing, it allows you to compose an email by dragging from predefined blocks with variables. So you only write your blocks once, and then you only combine them with drag and drop into an email. You can also save a set of email blocks as a template. When you choose that template, it lets you fill the variables of the template like a form, and then send it. We only use it internally and now with all the gpt stuff going on it seems pointless to release it. or is it? 🤔

New short course: LLMs as Operating Systems: Agent Memory, created with Letta, and taught by its founders Charles Packer and Sarah Wooders. An LLM's input context window has limited space. Using a longer input context also costs more and results in slower processing. So, managing what's stored in this context window is important. In the innovative paper MemGPT: Towards LLMs as Operating Systems, its authors (which include the instructors) proposed using an LLM agent to manage this context window. Their system uses a large persistent memory that stores everything that could be included in the input context, and an agent decides what is actually included. Take the example of building a chatbot that needs to remember what's been said earlier in a conversation (perhaps over many days of interaction with a user). As the conversation's length grows, the memory management agent will move information from the input context to a persistent searchable database; summarize information to keep relevant facts in the input context; and restore relevant conversation elements from further back in time. This allows a chatbot to keep what's currently most relevant in its input context memory to generate the next response. When I read the original MemGPT paper, I thought it was an innovative technique for handling memory for LLMs. The open-source Letta framework, which we'll use in this course, makes MemGPT easy to implement. It adds memory to your LLM agents and gives them transparent long-term memory. In detail, you’ll learn: - How to build an agent that can edit its own limited input context memory, using tools and multi-step reasoning - What is a memory hierarchy (an idea from computer operating systems, which use a cache to speed up memory access), and how these ideas apply to managing the LLM input context (where the input context window is a "cache" storing the most relevant information; and an agent decides what to move in and out of this to/from a larger persistent storage system) - How to implement multi-agent collaboration by letting different agents share blocks of memory This course will give you a sophisticated understanding of memory management for LLMs, which is important for chatbots having long conversations, and for complex agentic workflows.

If you're worried that voting for me as an Independent candidate will split the vote in Chingford and Woodford Green, you shouldn’t be. I’ve spent years fighting IDS and the last thing I want is to see him keep his seat. So if you know someone that wants to vote for me but is worried by national polling, share this video and tell them these three simple things: 1. Two of the biggest tactical voting sites in this country have withdrawn their recommendation of voting Labour here to get the Tories out. 2. Our data, from thousands of random conversations in the constituency, show that I’m ahead in the race. The Faiza Shaheen campaign has the most votes pledged. 3. Labour are going to win in a national landslide, so we need a critical voice in Westminster holding them to account. Don’t risk Iain Duncan Smith getting back in, vote for the person actually invested in our community. Vote Faiza Shaheen, Independent, on 4 July.

If you're worried that voting for me as an Independent candidate will split the vote in Chingford and Woodford Green, you shouldn’t be. I’ve spent years fighting IDS and the last thing I want is to see him keep his seat.

What actually happens behind a transaction on Kryvora? When you click confirm, it may look like a simple action. But behind that single click, multiple layers of infrastructure can be working together. I like to imagine Kryvora as a financial city built on blockchain. 🏪 Swap is the marketplace. It gives users a place to exchange one digital asset for another. What looks like a simple asset swap on the interface is part of a larger system processing that transaction. 🌉 Bridge is the connection between regions. Digital assets can exist across different blockchain ecosystems. Kryvora Bridge acts as the connection that enables supported assets to move between supported networks, helping different ecosystems interact instead of remaining isolated. 🖥️ Nodes are the infrastructure behind the city. This is the layer users may not see, but it plays an important role behind the scenes. Nodes can operate around the clock, receiving, checking and updating information according to the network’s rules. And the more distributed the infrastructure becomes, the less the system needs to depend on a single point of operation. Think about a city with only one control station. If that station goes offline, the entire city could be affected. Now imagine many independent stations working together. Some may experience problems, but others can continue supporting the network. That is why Node operators are more than just participants. They contribute computing resources, connectivity and infrastructure that can help keep the network operating. And incentives can encourage more people to contribute those resources. So the bigger picture starts to become clear. Bridge connects ecosystems. Swap connects assets. The application connects users with the tools they need. Nodes connect those activities back to the network. Together, these layers create something much bigger than what we see on the screen. A transaction that looks like one simple click can involve digital assets, blockchain networks, applications and independent infrastructure working behind the scenes. That is the part I wanted to explore in this video. Because the interface shows us what we do. The infrastructure reveals what makes it possible. And as Kryvora continues to evolve, the more interesting question may not be what this infrastructure can do today, but what it could make possible tomorrow. This is my entry for #KryvoraCommunityChallenge2026, created to break down the technology in a way that is easier to understand. #Kryvora #Kryvorians @KryvoraNetwork The most important part of a network is sometimes the part you never see.

And here is the impact of that three car wreck, shown below by Andrew Leyden as it blocks access to the tunnel. Delays begin at the Pentagon on I-395N.
