OmniSet is expanding support for one of the strongest ecosystems in Web3. @solana assets will now move across OmniSet with unified liquidity, cryptographic guarantees, and sub 100ms finality! This gives builders a faster and more flexible way to work across chains.

Blockchains don't need to be fixed. They just need to be replaced. 🫳 🐴

@RosuGrigore @CryptoHayes @keoneHD @MaelstromFund Okay, but you cannot batch it until that data actually arrives at that node, and is de-conflicted... Which node generates which batch for which accounts? This little detail is extremely critical and determines the actual performance of the system.

Arthur Hayes@CryptoHayes·
I think @keoneHD made a valid point that @MaelstromFund past / present portcos that we advise and/or invested have big locked token supplies. My advice to founders is always get to 100% vested for the team and investors asap , ideally immediately. Then one of two things happens: 1. The price nukes to close to zero, and stays there if there is no organic demand based on usage. 2. Or the price dips and recovers because there is organic usage. I hope we have done our job as investors to only back projects that generate organic usage and thus in the medium run we will make money, and if we failed at our job we deserve to lose all our money. Unfortunately, no founder has taken this advice so I can’t point to a successful outcome based on this theory. Maybe Monad can be the first to prove me right, and the amazing tech can generate the usage to challenge $ETH and $SOL.

It's great pleasure to be on this exciting panel. Agentic payments and micropayments will put much higher demand on the throughput/TPS of crypto systems. Are we ready?
House of ZK@HouseofZK

This feature panel from Verifying Intelligence 3.0 breaks down why the new x4O2 payment standard is emerging as critical infrastructure for the agent-based economy and maps where zero-knowledge proofs extend X4O2 - enabling compliant yet privacy-preserving payments, verifiable identity without exposing sensitive data, and secure facilitator-free flows where trust is replaced by cryptography. Featuring: • @alicelingl, Host at @HouseofZK@0xThiru, DevRel Lead at @MetisL2@aurobindo_arman, Solutions Architect at @ZKVProtocol@bensepanski, CSO at @VeridiseInc@chenxiaohong, CTO at @pisquared Watch the full panel to understand why x4O2 is becoming foundational for autonomous payments and the future AI economy: youtube.com/watch?v=RwiK9P…

A total ordering of all the transactions is NOT necessary for decentralized payments or preventing double spending. Crypto ≠ Blockchain.

Basically you get the best from both optimistic rollups and ZK rollups: low fees, instant finality, with the highest level of security.

@bread_ when you say multi client is it dual-client validation between megaeth own validators and pi2 verifiers?

Some light reading for nerds amongst you. Mega will leverage Pi2 to have something akin to a multi-client implementation live day 1. Complete list of chains in this category: - Ethereum - Solana - MegaETH Interesting.

The h402 protocol makes it easier for existing web2 applications to integrate into web3 payments, as they just need to know how to compose HTTP responses without bothering with the blockchain details.

@CoorvinuuS @RosuGrigore But if an account really wants to break w.i. and somehow gets stuck, it needs to send a special message that asks all validators to reset their local lock on that account.

@RosuGrigore That makes perfect sense correctness guaranteed by construction is far stronger than fixing errors after the fact. But, If an account breaks weak independence and ends up in an inconsistent state, how will recovery work for that account?

@CoorvinuuS @RosuGrigore Good question. Firstly, we do believe that the weak independence property is sufficient for lots of applications, including payments and auctions. So one should really think twice before stepping out of this safe zone.

X Space Recap: FastSet isn’t just about being faster. It’s built to be limitless and verifiably true, the first protocol in Web3 designed for real scalability, real decentralization, and real trust. Every computation is correct by construction, meaning it runs with mathematical precision from the start, removing the room for errors, bugs, or malicious behavior. Why payments first @RosuGrigore brought it back to the original Web3 promise: peer to peer payments without intermediaries. Most blockchains still top out at tens, hundreds, or a few thousand TPS. FastSet is built to settle payments at the speed of the internet, with no built-in cap on throughput. Infinite scalability in plain terms When Pi Squared says infinitely scalable, they mean capacity grows linearly as you add validators and parallelism. The protocol has no theoretical TPS ceiling. In practice you are bounded by bandwidth and local hardware, not by global consensus mechanics. Numbers so far Recent public runs crossed ~140,000 TPS with sub-100 ms settlement. The plan is to mainnet at 1 million TPS and scale to 10 million TPS within a few years as validator hardware and bandwidth improve. The big shift: from total order to parallel settlement Blockchains prevent double spend by forcing a single global order. That is powerful and also the main bottleneck. FastSet uses strong eventual consistency with local per-account order, so independent actions settle in parallel. Result: fully parallel claim settlement where one claim does not wait on another. Separation of roles FastSet cleanly separates verifiers and validators. 🟣 Verifiers check computations in their native semantics and sign the claim that state S1 can become S2. 🟣Validators verify those signatures and settle the state change quickly and in parallel.Think judges checking a signed statement instead of rewatching the entire footage. Programmability without barriers Developers are not locked into one VM or niche language. FastSet is designed for any programming language through language SDKs and verifier modules. EVM and WASM come first, with RISC-V and LLVM on the roadmap. Use Python, Rust, Java, C++ or Solidity and plug into the same settlement layer. Correct by construction FastSet executes verifiably as it happens. Every computation carries its own proof, making correctness part of how the system works from the start. Verifiers ensure mathematical precision, and validators deliver instant finality. What ships this to users 🟣 Payments for people and AI agents that settle instantly 🟣 Stablecoin issuers that want uncapped throughput and native cross-chain access via OmniSet 🟣 DeFi that benefits from parallel settlement while apps that truly need total order can implement their own fair sequencing Key quotes “There is no cap on how many payments per second can be settled.” “Strong consistency is the killer of performance. Once you discover strong eventual consistency, you will not go back.” “The validator does not need to know the language. It checks the verifier’s signatures and settles the claim.” “We do not verify after the fact. We generate executions correct by construction.” What to watch next 🟣 Sustained six figure TPS as a floor, not a peak 🟣 Mainnet aimed at 1 million TPS 🟣 Rapid expansion of language support through verifier modules 🟣 Payments as the first major wave, with AI micropayments close behind Try it yourself See parallel settlement in action. Explore the FastSet tools, kick the tires, and tell us what you think. pi2.network/fastset-network
