In the 90s, the UN thought a lot about e-commerce and the Internet. Unlike most, they had a place to start from.

Every agreement requires at least two utterances, an offer and an acceptance. That is the minimum requirement for a meeting of minds.
It is not necessary that these utterances are directed towards a specific party, but they do need to have a known origin. Ex. I can make an offer to sell my Mars bar to anyone, but someone accepting it cannot answer as humanity in general. They may answer to humanity in general, since this includes me.

Here is, in the author’s opinion, the simplest smart contract we can write in Solidity that has any use as an agreement or contract.

A while ago I was in a group discussion about how to make gold a decentralised currency on the internet. Ultimately we couldn’t find a structure which accommodated decentralised issuance while remaining a fungible currency.

Like the much maligned GOTO statement, the private blockchain, as a means to data privacy or tighter governance, should be considered harmful. (Although like the GOTO statement, it might still sometimes be a lesser evil.)
Why? Because the security properties of blockchains (and many other distributed data structures) rely on all transactions being visible to all participants. Once a system has enough participants to be useful, at least one of those participants will have included a compromised device.

This is a proposed blockchain powered online privacy standard. It came from discussions I had with Simon Deane-Johns [our lawyer at Zopa and a contributor to the Midata initiative]. The nicer legal wording is to his credit; any design errors are to mine.

(I am going to assume the reader is a software developer who's interested in programmable blockchains. If you feel confused by smart contracts etc, go read
Programmable Blockchains in Context by Vinay Gupta, who explains them far better than I do!)

I gave a little talk on Ethereum at the Bitcoin Assembly at the Chaos Communication Conference in Hamburg this year. Mostly because I was surprised not to see it covered. Not sure about my delivery, but people asked questions afterwards so I guess I didn't do to badly :-)
