Cubane is a SaaS-infrastructure Layer-1 RDBMS blockchain designed to bring the new power of decentralization to industries like insurance, media-IPR, RWA and beyond. We’ve developed our own proprietary Cubic Consensus Mechanism (CCCM) a hybrid technology that combines on-chain timestamping, equity-based validation, and advanced protocols like PoS, PoET, HLTC, FHE, ZKs, and an on-chain relational custom query database management system.

AxiomPay is a privacy preserving protocol for Stablecoin payments The stablecoin market is growing rapidly on Ethereum but true adoption of stablecoins for payments is still limited by a lack of privacy on the blockchain. With the constant improvement of on-chain tracking & analysis tools, we see three key problems with Stablecoin payments: (1) Account Balances Leaked (2) Transaction data details Leaked (3) Disclosure of payment execution relationship Graphs AxiomPay aims to expand…

The ecosystem includes Decentraclasses (Learn-to-Earn platform), BlockDevs (developer cohorts), and InstaLearn (AI tutor). AcadLayer provides modular APIs and SDKs for easy integration, fostering a permissionless, on-chain education economy.…

Colibri is a fully stateless, trustless verification client for Ethereum and other blockchain networks. Instead of blindly trusting RPC providers, Colibri allows wallets, dApps, AI agents, IoT devices, and backend systems to verify blockchain data locally using cryptographic proofs. The client validates both execution-layer data and consensus-layer correctness without syncing the chain, storing blockchain state, or relying on trusted infrastructure. Colibri brings proof-based verification…

Contract Level Compliance (CLC) embeds regulatory compliance directly into smart contracts. It achieves this by using Chainlink to check if an onchain user has completed KYC (Know Your Customer) with a licensed entity, before executing custom smart contract logic on their behalf. This ensures only compliant users can participate in regulated smart contracts. No user data is ever revealed onchain except for a "yes" or "no" to the question "Has this user completed KYC with a licensed…

Onchainsupply is building modular, composable on-chain infrastructure designed to empower the next generation of developers, enterprises, and autonomous agents. By providing a stack of interoperable tools—from smart assets and encrypted storage to gasless smart accounts and prebuilt dApps—we enable seamless, secure, and efficient on-chain interactions without complexity. Our platform acts as a foundational layer that bridges the gap between core blockchain infrastructure and usable…

Guardian Account Abstraction is a blockchain security infrastructure protocol that aims to enhance the overall security and usability of smart contracts in the development of decentralized applications. The protocol's key features include: - Multi-phase security architecture - Role-based access control - Time-delayed operations - Meta-transaction support Guardian AA aims to have the following impacts: - Improved security for digital assets by reducing the risk of private key…

## 🌀 Resi Protocol **Resi Protocol** is a **zero-knowledge-first**, algorithmic stablecoin platform that combines **real-time machine learning**, **adaptive monetary policy**, and **resilient oracle security** to create the next generation of DeFi stability infrastructure. --- ### 🔐 Foundational Principles Unlike previous stablecoin attempts, Resi is designed from the ground up with two core innovations: - **Zero-Knowledge Proofs (ZKPs)** integrated at every layer — from governance and…

ethOS is the first eth-based mobile OS. It integrates L2s, Light nodes and a system level wallet at the operating system layer, enabling crypto to break free of the mobile duopoly. Our recent dGEN1 device has over 6000 pre-orders, bringing an onchain portal to the palm of your hand and making ETH a first-class citizen on the device.

Due to emerging risks affecting Ethereum, core development, and its validator set, a group of teams and individuals is working on Commit-Boost, a public good initiative. Commit-Boost is an open-source Ethereum validator sidecar designed to standardize the final stage of communication between validators and proposer commitment protocols. Developed from scratch in Rust with contributions from over 20 teams across Ethereum, Commit-Boost is built with safety and modularity at its core. It is…
