Public blockchains allow insertion of arbitrary data. Even specific-purpose blockchains like Bitcoin already contain a lot of non-financial data. Although this data insertion can be beneficial in some use cases (e.g. proof of existence), it can also cause damage. If a blockchain contained videos with instructions on how to torture someone, there would immediately be broad consensus that this data must be deleted. But since blockchains are supposed to be immutable databases, the question is: what can be done if this happens?

Another approach uses cryptocurrencies in the blockchain, having the advantage of allowing exact […]

The crypto market is still inefficient. Cryptoassets have different rates on different exchanges. The big question is how we can profit from that inefficiency. One approach is making transactions between exchanges, but if we buy a cryptoasset on one exchange, by the time we can sell it on another, the price difference may no longer […]
