According to a blog post by The Israel Times, central banks around the world are acquiring mature blockchain infrastructure built through massive private sector investment and trial-and-error at extremely low or even "free" costs. The article states that from November 2021 to the end of 2022, the total market capitalization of the crypto market fell from approximately $3 trillion to about $800 billion, but the underlying technical architecture was still preserved. Currently, projects such as the Bank for International Settlements' (BIS) mBridge initiative, the European Central Bank's digital euro prototype, and related tests of the Israeli digital shekel are all built on technological achievements refined over years by the private sector to varying degrees. The article points out that this model—where the private sector bears the costs of trial-and-error and central banks take over the results once mature—may weaken the motivation for future financial infrastructure innovation.
