We then discuss the public blockchain ledger and various solutions to two important problems that are constraints on the public blockchain’s trustless consensus, viz. “mining” costs in proof-of-work and governance issues. We speculate that foreseeable institutional implementations will often involve integration of permissioned blockchains with public blockchains. We then discuss exchanges for trading cryptocurrencies, the second component of the crypto blockchains, and in particular their “teething problems” along with the evolution of a subset of them into increasingly “industrial strength” entities. We suggest that with a more industrial strength infrastructure in place, self-executing smart contracts are virtually natural counterparts for more traditional passive investment products. We end with a discussion of Security Token Offerings (STOs) and the newer Initial Coin Offerings (ICOs): STOs are an interesting hybrid between the ICOs and traditional IPOs; they could conceivably pave the way to a long-time-coming “direct electronic IPO” market.TOPICS: Currency, exchanges/markets/clearinghouses, exchange-traded funds and applicationsKey Findings• A set of crypto exchanges are evolving into institutional-strength entities with law-of-one-price, clearing and settlement, custody services, and user algorithms to deal with fake inflated trade volumes.• Pure public blockchains with well-known “blockchain trilemma” problems like high energy consumption, low performance, governance shortcomings, and no clear “how-to-pay” mechanism for ledger-updating in non-crypto applications, are inexorably leading towards hybrid public/permissioned blockchain networks.• Despite their rocky start, STOs and ICOs are leading to direct or electronic IPO markets, while smart contracts running on blockchains with securities trading identifiers and data seem ideal vehicles for administering passive investment products.
