The cross-border payment market is close to $200 trillion in size and is one of the largest financial flows in the world. Even today, payment and financing still rely on inefficient and expensive infrastructure: there are numerous intermediary links in banks, paper documents remain the core of trade financing, and there is a lack of instant trust verification between enterprises and banks. In this market, there are at least $2.5 trillion of cross-border financing pain points that have not been resolved for a long time. Recently, I have noticed that a decade old public chain @ iota has become active again. It has established a decentralized digital finance solution called Salus, which attempts to change cross-border finance and global trade order by endowing physical companies with digital identities, NFTs trade contracts, and smart data contracts. IOTA does not enter out of thin air, but relies on its two core advantages: Technical Base Upgrade -In May 2025, the Rebased mainnet upgrade will be completed, supporting 50000+TPS and 0.4 second confirmation time. -Dual virtual machine architecture: MoveVM L1+EVM L2, balancing security and programmability. This means that complex trade and financial activities worldwide can finally be settled in seconds on the chain. Compliance and Trust -Collaborate with compliance provider Lukka to integrate real-time compliance monitoring and risk assessment. -Obtained Islamic financial certification and government level endorsements such as the UAE Technology and Trade Fund. -Signed a cooperation agreement with GLEIF (Global Corporate Identity Foundation) to create verifiable on chain trust for enterprise interaction and trade networks. IOTA has built a Global Trade Information Network (TWIN) in collaboration with multiple government agencies, with the aim of achieving real-time and secure data sharing between global supply chains and enabling paperless cross-border trade. In the TWIN pilot results, transaction costs have been reduced by 80%, efficiency of small and medium-sized enterprises has been improved by 35%, and border processes have been significantly simplified, resulting in increased trade efficiency. Ten years is considered a long life for a blockchain project, and relying solely on narrative hype cannot survive for so long. It is necessary to continuously update the technological architecture to meet the real needs of the real world. IOTA proves that blockchain is not only a reconstruction of the financial system, but also can change productivity. We look forward to the implementation of more real use cases in the future. At the same time, I have also developed an interest in established public chains and will explore new trends in some of the older chains that are still being built.
