- Tiger Research said the network Maroo has been unveiled to reflect South Korean financial regulations directly on a blockchain.
- It said Maroo uses a Legal Oracle Committee and a Programmable Compliance Layer (PCL) to apply regulatory changes across all services on the network at once.
- Tiger Research said Maroo’s potential use could grow with the adoption of the won-based stablecoin OKRW and the February 2027 implementation of the Electronic Securities Act, along with discussions on institutionalizing won-based stablecoins.
Forecast Trend Report by Period
A new blockchain network designed to embed South Korean financial regulations directly into its protocol has been unveiled. The network, called Maroo, is led by Hashed Open Finance, an affiliate of Hashed. Its core feature is that when regulations change, every connected service adopts the new standards simultaneously.
Tiger Research, a Web3 market research firm, said on Sept. 17 that it had published a report analyzing Maroo’s structure and potential applications. The report said compliance systems at South Korean financial firms are currently dispersed across each company’s code base. As a result, companies must separately revise their systems whenever rules such as the travel rule are changed.
Maroo is designed to solve that problem by applying compliance standards at the blockchain level rather than within individual services. A “Legal Oracle Committee,” formed on the premise of participation by supervisory authorities, financial companies and legal institutions, sets the regulatory data. A “Programmable Compliance Layer,” or PCL, checks every transaction against those standards before execution. Transactions that violate the rules are blocked before they are recorded on the blockchain.
When regulations change, only the relevant parameters need to be revised for the new standards to be applied across all services on the network at once. Tiger Research said the structure could see strong use in South Korea, where virtual-asset transactions are required to transmit sender and recipient information regardless of amount.
Another key feature is the adoption of the won-denominated stablecoin OKRW as the network’s base settlement unit. On blockchains where fees are paid in volatile crypto assets, user costs can jump when network congestion coincides with rising token prices. Maroo was designed to use a won-based asset so fee volatility is limited to network congestion. Issuance authority for OKRW will be managed by the protocol’s governance.
Maroo also established a separate mainnet to secure control over the network. In emergency situations such as hacks or illicit fund transfers, the protocol can freeze or recover assets, or reissue them to provide redress for losses. Transaction data is disclosed only to the parties involved through zero-knowledge proofs. Supervisory agencies, however, can review the details with an audit key if legal requirements are met.
The project’s partners include ShardLab, which has built stablecoin payment infrastructure in Southeast Asia, and Delight Labs, which has experience operating multiple mainnets. All three organizations, including Hashed Open Finance, have development teams in Seoul.
Tiger Research said Maroo’s potential use could expand as South Korea’s Electronic Securities Act takes effect in February 2027 and discussions on institutionalizing won-based stablecoins advance. The two frameworks could be linked as the market develops settlement tools for tokenized securities, creating demand for infrastructure that can accommodate a range of regulatory scenarios.
“It is difficult to secure enough time to gain a market lead if institutions wait until the rules are finalized before choosing infrastructure,” Yoon Seung-sik, head of research at Tiger Research, said. “A more practical task for institutions is to validate in advance infrastructure that can reflect whatever direction regulation ultimately takes.”
