How do top investment banks use blockchain? Aren't they afraid of leaks? Although not as exaggerated as many Hollywood blockbusters, traditional financial institutions do have a lot of confidential information, especially when it comes to transactions, customer identities, and so on. I am curious, blockchain is open and transparent. How can banks use blockchain? If a private blockchain is used, wouldn't ordinary people be unable to participate? Even with a private blockchain, how can privacy be protected? Let's dive in! ⬇️ A cruel fact: most of the high-quality financial assets on Earth are locked in the private networks of banks, serving only super large corporations, conglomerates, governments, and tycoons that ordinary people cannot access. Oh, maybe you can see it in movies and TV shows. These 'hidden' assets and transactions also need to constantly embrace new technologies, and blockchain has become the industry's preferred infrastructure. In this world visible only to a few people, a hidden version of blockchain is strongly driven by @ Raylslabs. The design concept of Rayls is very clever, it is not to demolish the wall mentioned above, but to install a "smart door" on the wall that is both safe and participatory. Extract keywords: safety, participation. safety This has to mention Rayls' core technology Enygma. This is a programmable privacy layer that integrates fully homomorphic encryption, zero knowledge proofs, private message labels, and key pair control systems. It can enable confidential transactions and data sharing on an EVM compatible blockchain, allowing both individual users and large enterprises to use Enygma to ensure that their data is always secure, private, and verifiable. Enygma has two core functions, namely confidential transfer and cash to money/payment to payment, both of which are relatively unfamiliar financial terms. Confidential transfer refers to the private and secure payment or token transfer that banks can achieve; Cash to money/payment to payment is a private asset exchange that allows for the exchange of cryptocurrencies, stablecoins, and even NFT assets. participate Returning to the beginning, ordinary retail investors are unable to participate in high-quality assets and products in traditional finance. Thanks to the dual track system of privacy nodes and public chains, Rayls has broken through this wall, allowing retail investors to also participate. Specifically, in terms of architecture: On the private side, in simple terms, this is the exclusive 'privacy node' of financial institutions. Financial institutions can operate fully private, EVM compatible blockchain. Here, sensitive hidden assets are safely tokenized for the first time. All transaction data is 100% confidential and fully complies with existing financial regulatory and compliance requirements, which can completely solve the core fear of data leakage for banks. The public side can be understood as an open global liquidity layer. This is a high-performance EVM Layer 1 public chain that gathers DeFi protocols and liquidity from around the world. Here, ordinary retail investors can directly participate through a public chain compatible with EVM and complete the vast majority of Defi operations. However, the current products and services are bank level and enterprise level. / Rayls is not just having ideas. In fact, Rayls has already created $1 billion in revenue through a super institutional level, interest bearing asset channel, and partner AmFi; Carry out large-scale integrated business with Nimofast in Brazil; Tether is also a partner, and its core developers are supported by Tether. In the future, I will pay more attention to blockchain+traditional financial projects. I believe this is one of the main branches of the future direction, and currently, the vast majority of people in the cryptocurrency industry are not very familiar with it, which can be considered as a differentiated content positioning.
