Samsung SDS has landed a contract to build a blockchain platform for Korea Securities Depository (KSD), the country's central securities depository. The platform will handle tokenized securities, putting infrastructure in place ahead of South Korea's updated regulatory framework for digital assets, which takes effect in 2027.
What the platform will do
The system is designed to issue, trade, and settle tokenized securities — think stocks or bonds represented as digital tokens on a blockchain. Samsung SDS, the IT and blockchain arm of the Samsung conglomerate, will develop the underlying ledger and integration with KSD's existing post-trade infrastructure. KSD itself acts as the central hub for clearing and settlement in Korea's capital markets.
Why 2027 matters
South Korea has been moving deliberately on digital securities regulation. The government plans to amend the Capital Markets Act to formally recognize tokenized securities and set licensing rules for issuers and platforms. That change is expected in 2027. By starting work now, KSD is making sure the plumbing is ready before the law kicks in. The timing isn't accidental — early movers in other jurisdictions, from Singapore to Switzerland, have shown that infrastructure often lags behind regulation.
Inside the deal
Samsung SDS brings enterprise blockchain experience from previous projects with Korean banks and logistics firms. For this contract, it will likely use its own Nexledger platform — a permissioned blockchain tailored for high-throughput financial use cases. The deal hasn't been publicly valued, but it signals that KSD sees tokenized securities as a core part of its future rather than an experiment.
The depository also runs Korea's existing electronic securities system, so this isn't a replacement from scratch. The new platform will probably run in parallel, handling only tokenized instruments at first. Over time, regulators and market participants will decide how much of the legacy system migrates.
KSD and Samsung SDS haven't disclosed a timeline beyond the 2027 regulatory deadline. But building a production-grade blockchain platform for a central securities depository typically takes 12 to 18 months. That means testing and pilot launches could begin as early as late 2026. The real question is whether Korea's brokerages and asset managers will have their own systems ready to plug into KSD's new rails in time.
