Samsung is becoming increasingly active in the cryptocurrency space. In addition to investing $2.9 million in Ledger, a popular cryptocurrency hardware wallet manufacturer, Samsung's blockchain task force is currently developing a blockchain mainnet based on ethereum and may also later launch its own cryptocurrency, "Samsung Coin." Although these developments are still in their early stages, the tech giant's patent portfolio, as diversified as it is, is making its way into the Cryptocurrency sector. There was a surge in blockchain-related patent application filings in early 2018, suggesting that Samsung only recently set its eyes on the crypto market.
