| Old thread, I know. But there are a few: * Transaction throughput. * Efficiency - allowing small scale players to participate in verification and block production. * Inter-chain communication - some networks are explicitly designed as connected swarms of chains (Cosmos and polkadot for example) and some evolving into that direction outside of the protocol level (Ethereum). How do execute transactions that span the networks is an ongoing research topic. * Privacy - how to execute transactions in private. How to attest that something is true, say that you have a certain credential, without exposing your account information. Blockchain has been why zero knowledge (and now homo-morphic encryption it seems) cryptography are becoming an active field of research. * Identity, authentication, account recovery. - these tie into cryptography but generally research on applied cryptography with good UX. For example the first time I've seen social-recovery accounts with any amount of usage (now a feature in Apple accounts) was in a blockchain application. * Monetary research - far from everybody involved in crypto believes that a fixed-supply rare item makes for good money. "Fiat" money is basically a "token" with governance attached to it. This has lead to a wave of experimentation with other forms of tokens - ones that are algorithmically tied to other assets, ones that are backed by an organization, local currencies, etc. * Organizational research - since smart contracts can effectively be transparent community banks there's has been a plethora of experiments with building organizations that manage their own treasuries. Horizontalism, organizational transparency and cooperation is something that's been at the core of many crypto projects, the idea being that something cannot be both a reliable public good and controlled by a single party. It's not an easy task, but some cool organizations have come out of this. For an example look at pocket: https://messari.io/report/governor-note-proof-of-participati... |
