Sui consensus skips the certification round that older designs required Validators on Sui all propose blocks at once instead of taking turns. Older designs required each block to collect signatures from a quorum of validators before it counted, and that's where the time savings lived. Mysticeti cuts the wait,...

Category Labs is proud to introduce Cadence, our multiple-concurrent-proposers (MCP) consensus protocol that matches the optimal good-case latency of single-leader consensus while supporting arbitrarily short block intervals. When combined with BTX, our design for encrypted mempools, this represents a significant step towards solving the problem of MEV at the protocol level. In nearly every blockchain today, a single party ends up in control of each block: it decides which transactions get in, and can reorder them at will. MCP is the natural fix, but most recent designs pay for it with a separate aggregation phase, adding two extra communication rounds per block. Cadence makes the proposers part of consensus itself. Its fast path finalizes in an optimal three communication rounds, even when proposers are offline. Cadence also offers speculative finality, similar to MonadBFT, after just two rounds, revertible only if a proposer provably equivocated. In a simulation using estimated network delays between Monad mainnet's 200 globally distributed validators, finalization takes 219 ms on average, speculative finality 167 ms. Cadence pushes pipelining to the extreme: each block is proposed and finalized in its own independent consensus instance, without waiting on preceding blocks. The block interval then becomes a protocol parameter that can be arbitrarily small. At our initial target of 100 ms, a transaction waits on average just 50 ms to enter a proposal, and oracle prices, liquidations, and auctions can update every 100 ms. Cadence dynamically throttles the opening of new instances to bound the number of outstanding slots even during periods of network instability. When the network is healthy (under synchrony), a transaction included by an honest proposer can be neither dropped nor deferred (short-term censorship resistance), and no proposer can see the others' proposals in time to react (hiding). We prove both, together with safety and liveness under partial synchrony at the optimal 3f+1 fault bound. The Cadence protocol is modular: each module is simple on its own, and any of them can be swapped out without touching the rest. Cadence also builds on components already being deployed: proposals are disseminated as erasure-coded chunks over Deterministic RaptorCast, now rolling out on Monad, and validators vote on proposal digests, so voting does not wait for the full data to arrive. Start with the interactive tutorial: Full paper: Joint work by Kushal Babel, Fatima Elsheimy, Lioba Heimbach, Mohammad Mussadiq Jalalzai, Tobias Klenze, Jovan Komatovic, Jason Milionis, Mike Setrin, and Victor Shoup.

Trust is the hardest thing to build in finance. This is why ADI Chain is building it twice. Every transaction batch on ADI Chain gets verified by zero-knowledge proofs before it settles. That path has carried the chain since day one, and the cryptography behind it underpins the chain's settlement guarantees. A second verification path is now taking shape alongside it. The same verifier runs inside Intel TDX, hardware that seals off the code and can prove to the outside world exactly what was loaded. Inside that sealed environment, the verifier replays the batch, signs off using the approval format the chain already accepts, and returns the result through the route it always takes. Trust in financial infrastructure is rarely built on a single guarantee. Institutions moving real value want to know that if one check fails, another one still holds. Zero-knowledge proofs confirm the math is correct. A hardware-isolated verifier confirms that the environment producing the result is the one it claims to be. Two different jobs, and neither one replaces the other. This is how ADI Chain is designed to serve the institutions moving onto it.

Every man lives two lives. The second begins when he realises that he can max out hypertrophy in 15 second sets. Four or five reps build muscle. The last four or five, where the bar slows on its own whether you like it or not. That is where the high-threshold motor units finally get called up. Where the cross-bridges are attached in maximum number at once. Where the fibre takes the tension it has been waiting all set for. Mechanical tension is the only language the muscle reads. It does not have a second one. Everything either side of that is filler, and somebody is paid to sell you filler. Tempo is filler. You are 30 to 50 per cent stronger lowering a weight than lifting it, so no descent on earth is slow enough to threaten you. Drag it out and all you have done is put a lighter weight on the half that counted. The pump is filler. Lactate infused straight into the blood grows nothing. Blood flow restricted on a resting muscle grows nothing. Swelling is a feeling and it gets no vote. The mind-muscle connection is filler. You cannot instruct a muscle in which fibres to use. You tell it to contract. The load decides the rest. So: a weight where the fourth rep slows by itself. Drive it. Stop one short. Rack it. Fifteen seconds. That set has already delivered everything your three sets of twelve spent forty minutes promising. Nobody has ever built a business on fifteen seconds of hard work, so they built one on everything you could bolt onto it.

Pectra Upgrade: Official Statement Not every upgrade goes as planned, and that’s how progress happens. ⚙️ Pectra was meant to push our EVM layer further. For a week, everything ran flawlessly… until we hit a rare consensus edge case that caused block forks under heavy load. Instead of patching on the fly, we made the call to roll back to the previous version, prioritizing stability and learning from the failure. Now we’re working closely with the Substrate team to pinpoint the cause and come back stronger with a safer, faster, and smarter upgrade path. Every failed upgrade is a step toward a flawless one. 💥 Big thanks to our validators, devs, and community for the quick reaction and resilience.

DIVINE CHAPTER - First looks at early designs! The first one is Ray of Retribution which is a beam of light sent out as an attack, and that also applies “sin” The second is Hopeless Exile, a separate Realm the Killer pulls you into. It will have Pillars of Light (also seen in third image) you have to dodge, and “blue lights” you have to collect to help you escape this mini-realm. The last one is an early animation for praying at the Killer’s shrine(s) to remove sin from yourself!

I'm not sure about you, but I had no idea until now that the ending of Psycho (released across the USA on this day, September 8, 1960) involves a superimposition of three elements that many people fail to notice. The last shot of Norman Bates’ face has a still frame of a human skull superimposed on it. That skull is his Mother’s. This dissolves into a shot of the chain pulling out Marion’s car out of the swamp. The chain is placed so that it appears to be moving through where Norman/Mother’s heart would be, symbolically showing that the two are tied together. I have slowed down the movie frames considerably so you can see the superimposition for yourself.

TIMED DIALOGUE IN A NIGHTCLUB. THREE WALLS FALL AT ONCE. Nightclub sketch, cut in two halves. Black-and-white first - a couple making out on a couch, someone laughing off-camera. Then color reveals the setup: guy walks up with a drink, delivers a line, she gives him a one-sentence answer that changes the picture, he pauses, then kisses her anyway. None of them exist. It's fully generated, both halves. - What used to be four problems is now one clip Character consistency across a cut - same two faces in B&W and in color. Two-person dialogue with alternating lip sync - three separate English lines, all on time, all matching mouth shapes. Nightclub lighting - low light, saturated color wash, moving sources - was the last hard lighting environment for AI video to render without collapsing into noise. And a kiss - two faces contacting without merging into each other, which has been one of the persistent tells. Any one of these has been solvable for maybe six months. All four in one sketch was still a demo-reel problem in early 2026. - The B&W cut is doing two jobs The editing choice isn't style. It's engineering. Splitting a 15-second sketch into two 5-7 second clips means the model only has to hold consistency inside each segment, not across the whole thing. Monochrome also hides small differences between the two generations - if the girl's face is 3% off between the halves, B&W flattens the delta. Color grading in the second half does the reverse job. Two seams, both hidden by the aesthetic. - The comic beat is the actual craft Generating a kiss is one problem. Generating a kiss that lands as a punchline is a different one. The half-second where he pauses, processes, and decides not to care - that timing has to be prompted specifically. The default output of every current model is a rushed sequence with no beats. Deadpan comic delivery out of AI video means the operator wrote the prompt the way a screenwriter would - pauses, reactions, holds, all specified frame by frame. - What it costs Two 5-7 second clips at $3-5 each with in-model audio. Locked character references for both actors so the faces match across the cut. Prompt structured as a mini-script with beat notation. Realistically 40-60 rerolls to land the timing on all three spoken lines and the kiss. Under $200 in compute. A weekend from concept to publish-ready. - What this actually opens Short-form comedy has been the one segment of content nobody was making with AI video yet, because you can't fake comic timing when your output has drift and glitches. That barrier just came down. Which means every sketch account, every meme page, every stand-up clip factory now has a pipeline that doesn't require booking actors, renting a location, or getting a laugh out of a live crew. That's a real shift in a market that produces billions of views a month.

🔥Another lonesome Russian invader dressed as a penguin was destroyed by the Armed Forces of Ukraine When the MoD of the Russia said that they would issue a new "Arctic" uniform, Private Ivanov did not expect that it was just a prop from an abandoned children's theater. Now he is the only one in the position who looks official - as if he was going to a session in "Madagascar", but instead of "smile and wave" it turns out "freeze and lie down".

Apparently, I saw this video online and I decided to share. What this worker is applying is called bitumen, or what many of us know as bituminous coating. Most people think a wall is a solid, impenetrable block, but in reality, it is more like a sponge. Concrete and blocks have microscopic pores that pull water from the earth through a process we call capillary action. This thick black substance is the shield that stops that water from climbing up into the house. It is not about making the wall look good because this part will be buried under the dirt forever. It is about creating a skin that water cannot breathe through. When do you need to do this? The need for this arises because the soil is a very aggressive environment. Water is not your only enemy.. The ground also contains salts and sulfates that want to eat away at the cement. If this moisture finds its way to the steel bars inside the columns, those bars will start to rust. And when steel rusts, it expands, and that expansion is what cracks the concrete from the inside out. This coating is the only thing standing between your foundation and that kind of slow destruction. Thats is why if you see wet patches at the bottom of your walls inside your house, it usually means someone skipped this step or did it poorly during construction. You can apply this anytime you are building parts of a structure that will stay in contact with the ground. It is common in areas where the water table is high or where the soil stays damp for most of the year. This is a one-shot opportunity. Once you backfill the soil, you can never go back to fix it without a lot of expense and a lot of digging. It is about having the foresight to protect the heart of the building while it is still exposed. Please don’t ignore this if you need to. If you ignore it now to save a bit of money, you will be funding the future decay of your own home. I hope this helps.

This is just one of the parts of my secret sauce that makes up ⚡️ Hyper Realism on Photo AI and Interior AI Really high definition crispy details at up to 24 megapixels and very fast too and the most detailed upscaler out there now Kinda obvious but just going super high in resolution solves most of the problems of AI photos because every tiny detail (like a tiny hair on a skin) becomes a 640x480 block that can be generated by AI much more accurately than trying to do it as a few pixels It's made by my old AI dev philz1337x and for everyone to use at clarityai .co, I'm not affiliated but he's my friend and I use it!

From International Space Station, we have a unique vantage point to observe lightning storms from directly above them. Much like from the ground, they appear as rapid, intense flashes that are over as quickly as they started. But, with the help of handheld cameras and a bit of practice (and, admittedly, some luck), we can capture these intense flashes with a very high frame rate then slow them down to see how the lightning propagates. It's lightning, in slow motion. This is one that occurred over Indonesia on 6/28. I shot it for a half second at 1/120 frame rate, so, 60 separate frames. I then compiled those frames into two videos: the first, in real-time, and the second, slowed down so that each frame is a half second to highlight the progression of the flash. Note the incredible burst of light in one frame, which includes what is likely a TLE on the upper left. A TLE, or Transient Luminous Event, is an electrical discharge that happens in the upper atmosphere above lightning storms (if you haven’t seen Ferry Farhan TLE photo from last week, head over to her page). As their name implies, these are transient, or short lived, phenomena – it appeared in only one frame of the sequence, lasting for no more than 1/120th of a second. The last photo is that single frame. Absolutely incredible.

It doesn’t matter what material you build your house from, when a fire, fueled by high winds hits, it’s not being saved. This is from a “small” recent fire in Gatlinburg area that got close to a house I owned. Took out quite a few homes. The wind just carries the sparks everywhere and often the fires start at the roof level (not the ground or side of the house). Once the roof area is hit, it’s all over. The fire will burn the house from the inside out. And it doesn’t matter if it’s a metal roof…think of all the wood components that metal roof attaches to and the eaves, soffits, etc. Just one spark can start a fire. When the wind is blowing at 60-80 mph gusts, you’re getting millions of sparks. The fires also get into the tree tops (especially of pine) and then balls of fire can also start raining down in clumps onto houses below as well. ICF, poured walls, concrete block….all irrelevant when you have a massive fire coming your way.

And it doesn’t matter if it’s a metal roof…think of all the wood components that metal roof attaches to and the eaves, soffits, etc. Just one spark can start a fire. When the wind is blowing at 60-80 mph gusts, you’re getting millions of sparks. The fires also get into the tree tops (especially of pine) and then balls of fire can also start raining down in clumps onto houses below as well. ICF, poured walls, concrete block….all irrelevant when you have a massive fire coming your way.

This was all streamed from Bitcoin using Ordinals. The 3D world supports real-time multiplayer interactions, and decentralized land ownership. All this is on-chain on Bitcoin, and as immutable and secure as Bitcoin itself. The weather in the world reacts to Bitcoin fees, clouds are linked to transaction volume, and time in the world is determined by block height. Makes sense for a Bitcoin world. Real-time multiplayer interactions is one of the newest features. This is particularly difficult to do because Bitcoin block times are ~10 minutes. Bitcoin has been around for 17 years, and we're now seeing fascinating new things being built on top of it.

**Traditional Engine Order Telegraphs:** The bridge unit and the engine-room unit are connected by two chains (or wire cables) that run through conduits over sprockets, forming a continuous loop. When the bridge officer moves the handle, it turns a sprocket that pulls the chain, which in turn turns the corresponding sprocket and pointer in the engine room. This classic system does not require electricity; it relies on a direct physical linkage, ensuring that both dials always mirror each other. Here’s a typical sequence of operations: The bridge officer grabs the handle and swings it to the command position, for example, "Half Ahead." This movement not only moves the engine-room pointer but also rings a bell or gong to alert the engineers. The engineers then adjust their own handle to match the position indicated by the bridge officer; this movement serves as an acknowledgment and rings the bell back on the bridge, confirming that the order has been received and understood. Only after this acknowledgment do the engineers work the throttle and reversing gear to carry out the order. It is common practice to first execute a full sweep of the handle, moving it all the way to one extreme and back before settling on the actual command position. This exaggerated motion serves two purposes: it rings the gong loudly and unmistakably, ensuring everyone is aware that a new order is coming, and it checks that the mechanism and chains are not stuck or slack. On some ships, this full sweep also signifies an important or urgent change (such as switching from ahead to astern), emphasizing to the crew that they need to pay attention because the situation is critical. After completing this sweep, the handle is adjusted to the desired position. This telegraph is from the Steamship Shieldhall (video credit as well). Go check her out on

A friend of mine just recently got his first gun, a striker fired Glock 19. He is terrified to leave a round chambered. To anyone reading this who has this same fear, I want to alleviate your concerns. I'm going to explain why there is nothing to be afraid of. First and foremost, I fully understand your concern. It's not irrational. And you're not stupid for being nervous about a bullet being aimed at your leg with the striker cocked back under spring tension about an 1/8 of an inch from the primer. I get it. I shared this concern when I was new to carrying. But your fear is due to a lack of understanding of the internal safety features of a modern striker fired handgun. On a properly maintained modern striker fired pistol the striker CANNOT hit the primer on the chambered round without the trigger being pulled. Can't. Not shouldn't. Can't. (If you have any good Sig P320 jokes, this is the proper place to share them) There is a block that the striker will hit and stop if it is released without the trigger being depressed. It works just like a lock and key. There is a channel in the blocker that the striker can pass through if it is in the fire position. It only goes into the fire position if the trigger is pulled which pushes the blocker into the fire position. A spring keeps the blocker firmly in the block position until then. The blocker is a solid piece of steel that won't break. And if your gun is securely in a hard sided Kydex holster nothing can move the trigger unless it is unholstered. Many guns like Glocks have a trigger safety that prevents the trigger from moving due to force of dropping. Your finger has to be on the trigger safety to move it. So the gun cannot fire unless you pull the trigger. And it's easy for you to test this safety feature to see how it works! See the video below. You can try to push the striker forward by moving that piece at the back of the slide forward. That piece is the back of the striker. Push it forward and it will stop. The tip won't come out through the breach. You see it trying to come through but it gets stuck. Now push that little button in. That is the actual blocker. When you push it in you will now be able to move the striker forward through the breach and see how it will strike the primer. You can test this easily every time you disassemble your pistol to verify it is still working. You can break this safety feature by removing the blocker or losing the spring. But if it's there it will work. (You would be the first person in firearms history who has ever lost a spring. Literally the first one. It has never happened before. 😐) But it doesn't come out as part of regular maintenance. You have to disassemble the firing assembly to get it out. That won't happen by accident. And if you do that on purpose you should do this blocker test when you reassemble it to make sure the safety feature is working. My video shows a Glock slide. All Glocks will look like this. Other brands may put the blocker in a different spot or it may be a slightly different shape. But they all (mostly) have the same design. If you test yours as demonstrated and it works like mine does, your gun WILL NOT fire without pulling the trigger. (If you just thought of another P320 joke, this is another good place to toss that out there)

🇺🇦🇷🇺 A Ukrainian F-16 just shot down a Russian drone, and it's being hailed as a gamechanger Rather than using an interceptor missile that costs hundreds of thousands, it shot the drone down using its rotary Gatling gun that fires standard ammo costing around $34 a round Here's why it isn't as effective as it sounds The gun fires around 6,000 rounds a minute, which means it goes through $3,400 of ammo per second Still cheaper than an interceptor, even taking into account fuel and maintenance costs for the F-16, but... The real problem is Ukraine has less than 40 F-16s, and even with all its other jets, they have less than 140 If Russia launches a drone swarm, the likelihood of intercepting them with fighter jets is low, especially when you take into account the difficulties of getting that many jets into the air and managing the battle space so they don't hit each other Writer: Ian
