Rather than operating as an independent blockchain network, JSM is identified as a blockchain currency implemented through Mun ERC-20 smart contracts on Ethereum. Its stated purpose is to support activity inside Joseon, including government transactions, public services, commercial activity, and broader economic use. Outside Joseon, the project positions JSM as a foreign currency and as part of a legal and jurisdictional framework for crypto-related entities. Technically, JSM is best classified as a token rather than a standalone blockchain. The available data identifies an Ethereum contract address, Etherscan visibility, and Ethereum ecosystem classification, while no independent validator set, mining network, native consensus system, or node infrastructure was documented. Security therefore depends primarily on Ethereum's settlement layer and the integrity of the JSM smart contract. The DScore extraction notes that JSM uses Mun ERC-20 smart contracts and is established on the Ethereum blockchain. It also notes that CoinGecko warned that the smart-contract owner can mint new tokens, which is an important technical and tokenomic consideration for users evaluating supply certainty and governance risk. The project's described use cases center on currency functions within Joseon and a bridge between traditional financial systems and cryptocurrency. The source summary states that JSM may be used for government transactions, public services, commercial activity, international trade, and investment. Ecosystem visibility is largely market-data oriented: CoinMarketCap, CoinGecko, and TradingView provide price, supply, market, and chart information, while Etherscan provides contract-level visibility. Wallet support is broad for an ERC-20 style asset, with hardware, desktop, mobile, and browser-extension options listed, including Ledger, Electrum, MEW, MetaMask, Argent, Phantom, and Chrome Web Store extension support. Exchange access is entirely centralized in the provided data, with listings on Coinbase, Kraken, BitMart, LBank, DigiFinex, Biconomy.com, and LATOKEN. JSM's supply model is capped in the available market data at 2.4 trillion tokens, with the same figure reported as both total and maximum supply. Circulating supply was listed as 316.47 billion JSM, equal to 13.18625 percent of maximum supply in the extracted snapshot. No ICO amount, token sale terms, insider allocation, public initial distribution percentage, fair-launch evidence, treasury policy, or ongoing development-fund mechanism was documented. The token is therefore not described as a fair-launch asset in the source material, and the initial distribution remains opaque. Market milestones in the summary include an all-time high of $0.01509 on July 9, 2024, and an all-time low of $0.0001252 on March 19, 2026. Governance appears to be off-chain and tied to Joseon's national governance framework rather than a token-holder DAO. The DScore extraction explicitly says no on-chain DAO was found and references the Code of National Governance as the stated governance framework. No CEO was identified, no venture-capital funding information was found, and no official GitHub repository or open-source license information was present in the provided data. Development activity is therefore difficult to assess from the master summary alone. The main roadmap-like signals are narrative rather than technical: Joseon's cyber nation positioning, JSM's intended role as national currency, and continued market infrastructure support through analytics platforms, exchanges, and Ethereum contract visibility.
