LBank पर Umbra (UMBRA) कैसे खरीदें

There are two distinct projects in the Web3 space associated with the name "Umbra" or "UMBRA". One project, often referred to as Umbra Protocol, is a privacy-preserving tool for the Ethereum blockchain and other EVM-compatible networks. This protocol introduces stealth addresses, which allow a sender to transfer Ether or ERC20 tokens to an address controlled by the receiver without revealing the receiver's identity on the blockchain. On-chain, such transactions appear as simple transfers to an unused address. Off-chain, the sender uses a public key to generate this new, unique address by encrypting the data used for its creation. The Umbra Protocol aims to enhance transaction privacy and supports Layer 2 networks, including Polygon, Optimism, and Arbitrum. It was developed by ScopeLift, led by Ben DiFrancesco, and originated from an ETHGlobal HackMoney hackathon in May 2020, officially launching in June 2021. It is described as a grant-funded public good project. The second project, referred to as UMBRA Network, is a sovereign Layer 1 blockchain primarily built for stablecoin applications, with a focus on speed, low costs, and privacy. This UMBRA Network aims to provide an infrastructure for efficient, secure, and reliable value transfer using stablecoins. Key features include high transaction speeds, with reported capabilities of 5,000+ transactions per second and 1-second confirmation times, along with zero transaction fees for stablecoin transfers. It also incorporates optional privacy features, allowing users to control their financial privacy while maintaining compliance. The UMBRA Network is designed for cross-chain interoperability and includes a built-in wallet and its own USUD stablecoin. This specific privacy protocol, powered by Arcium, aims for "auditable privacy" and supports both Solana and EVM networks. It has garnered significant attention, including through an Initial Coin Offering (ICO) on MetaDAO in late 2025. The native token associated with this blockchain is also referred to as UMBRA. अधिक जानकारी हासिल करें
