Yet these distributed ledger solutions keep being rolled out by enterprises in various settings – mostly still in experimental phases, but, increasingly, with real money at stake. And while they fall short of the public blockchain ideals of censorship resistance and permissionlessness, these contained, private experiments are extremely useful to the development of the overall blockchain industry.
While crypto investors lick their wounds in a bear market and developers plug away at scalability fixes for public blockchains, we can learn a great deal from how economic actors behave in these controlled situations where transactions involving multiple non-trusting parties are collectively recorded in a shared ledger.
One example came last month, with a first-of-its-kind blockchain bond issuance by the World Bank.
