After an incredibly successful week at Token2049, the highlight was undoubtedly presenting our SPIN whitepaper at the Bleeding Edge Summit! While still waiting for the official video, we would like to share a recording from the audience. With SPIN, we're introducing a revolutionary approach to building proof-of-stake blockchains. There is a well-known chicken and egg problem when it comes to launching a new proof-of-stake blockchain. You need high value at stake to achieve economic security, but at the same time, for achieving that, you already need to be secure. With SPIN, you can borrow security from well-established networks such as Polkadot or Ethereum. Unlike a Layer 2, which completely gives up chain sovereignty and frequently sacrifices scalability and throughput to satisfy Layer 1 validation protocols, SPIN maintains full sovereignty of the Fast Chain while still benefiting from the security of the Anchor Chain. Our SPIN protocol addresses this fundamental challenge by enabling a fast, sovereign chain to maintain and grow its economic security with its own validator network, while simultaneously leveraging an established anchor chain to provide a second layer of finality. With SPIN, we take an unlimited set of stakers, reduce it to a limited set of validators who can run very quickly, producing a consecutive sequence of blocks during their staker period. This design allows for blocks with very small block times, as low as 0.1 seconds and beyond. Our full SPIN whitepaper will be released soon.

Everyone talks about how Web3 will change the world. But the truth is: if you can’t make it work with the systems that already run the world TODAY, it doesn’t matter. Sometimes it feels like we "own" the Multiversᕽ blockchain. Not because we control it, but because every time we start researching a new module or flow, a new chain upgrade lands at the right moment, unlocking the exact functionality we need to build that idea. At Vero, we believe blockchain should stay invisible to the user. The real magic happens when it works silently in the background, even with old Web2 hardware, the kind that’s still required by law. In Romania, for example, every onsite sale needs a fiscal receipt. No exceptions. At the start of the year, we built a way for each point of sale to issue blockchain-connected fiscal receipts. But that meant one printer per station: expensive, inefficient, hard to scale. Now, after months of working, we’ve fixed that. Multiple POS stations, all connected to Web3, can now print on a single fiscal printer. Each receipt includes a unique station ID, a transaction hash, and is fully compliant with tax regulations. And we didn't stop there. We also built a full merchant module that handles both card and cash payments. VeroPay is now running as a SaaS infrastructure for any merchant, in any industry. With the latest MultiversX chain upgrades, this module is 100% live on mainnet. This is what we focus on at VeroPay: Not building DeFi tools that maybe 1% of Web3 users will ever try, but making sure blockchain works today, with the infrastructure that 99% of businesses already use. Maybe in 5 to 10 years everything will be on-chain, and that future is coming. But until then, the winning move is connecting invisible Web3 to the regulated Web2 systems already in place. That’s where real adoption begins. PS: Next up, we're working on a flow to export reports from explorer directly into major bookkeeping software format 👀

The “scientific consensus” talking point was succinctly dismantled by Dr. Judith Curry in her interview with John Stossel back in October. 𝗝𝗼𝗵𝗻 𝗦𝘁𝗼𝘀𝘀𝗲𝗹: “The overwhelming scientific consensus. That’s what people still believe.” 𝗗𝗿. 𝗝𝘂𝗱𝗶𝘁𝗵 𝗖𝘂𝗿𝗿𝘆: “. . . when you talk about ‘scientific consensus,’ like the Earth orbits the sun, you don’t need to say ‘There’s a consensus that the Earth orbits the sun,’ it’s a well-known fact. When you’re talking about consensus, it’s usually on a topic where there is disagreement, and a government has asked a group to come to some sort of an agreement on what’s what. You see it in science, you see it in. . . medical boards. . . So, it’s a manufactured consensus. It’s a consensus of scientists, which is different than a scientific consensus. . .” Dr. Curry goes on to explain that there is no consensus on the most contentious issues of climate change, such as extent of human contribution and the impacts. 𝗗𝗿. 𝗝𝘂𝗱𝗶𝘁𝗵 𝗖𝘂𝗿𝗿𝘆: “. . . there’s a true scientific consensus on very little of this, you know that, • The temperatures have been increasing for over a hundred years. • That burning of fossil fuels emits CO₂ into the atmosphere. • And, CO₂ has a radiation spectrum that sort of keeps the Earth’s surface warm, all other things being equal. Beyond that, there’s no real big consensus on anything. The most consequential issues we don’t have a consensus on: • How much of the recent warming is caused by fossil fuels? We still don’t know. • Is fossil fuel and is warming dangerous? This is the weakest part of the argument. There’s no agreement as to whether warming is dangerous.” 🔗 You can watch the full 40+ minute interview here:
