Shido has many important milestones ahead this year, with... the most significant being the launch of Nova EVM for the Shido Network, including both testnet and mainnet deployments. Nova is a complete rebuild of the Shido Network, featuring a new consensus protocol and a modular stack. This new design will enable Shido to unlock a range of powerful protocol-level features that support real-world use cases and institutional adoption. The Nova mainnet roadmap not only enhances the chain for DeFi and general computation, but also specifically optimizes it for privacy, stablecoin payments, and financial accounting. Key features on the Nova roadmap: • Gas fees paid in stablecoin at a fixed rate, with automatic conversion to the native Shido token. This optional feature removes gas price volatility and makes accounting and cost forecasting easier for businesses. • Optional privacy transactions designed with compliance in mind. While the Shido Network remains a public chain by default, it can support confidential transfers for users when required. • Reserved blockspace for stablecoin transfers. This ensures guaranteed throughput and enterprise-grade reliability for all stablecoin transactions. • Fee sponsorship, enabling gas-free payments for users when sponsored by applications, service providers, businesses, or the foundation. • An optimized token standard designed to support structured data. As Shido moves forward in 2026, detailed milestones and timelines will be announced for specific features and upgrades to the network. Learn more atshow more

"You're BlackRock and you send JP Morgan money from... one bank account to another. Would you want everybody to be able to see that?" "A lot of these chains, seeing the success of Canton and others, realize that institutions are not going to participate in crypto unless privacy is a given. Privacy, or we could even call it confidentiality in this case, like developing confidential transfers" "The problem with public blockchains is that you may not know it's my bank account and your bank account, but everybody can see where some money was sent, and with any decent onchain analysis, probably tie that to you. Institutions can't do that. The largest institutions on the planet need to know their transactions are completely confidential" "Ethereum Foundation researchers are launching an institutional grade privacy system called ETH Systems. They're developing confidential transfers, private bond issuance, privacy preserving identity, and confidential settlement systems designed specifically for institutional users"show more
