An important paper was published this week: If you’ve followed Bitcoin for any time, you’ll know this is a seriously eminent group of authors It describes a way to build “pegged sidechains”. Sidechains themselves are not new – the idea, and how to build them, has been discussed for some time and the key breakthrough was outlined earlier in the year. But this paper gives more detail on the concept and has attracted a lot of comment. But what are they? A mental model for Bitcoin The key to understanding most innovations in the Bitcoin space is to make sure you have the right mental model for how Bitcoin itself works. To help with this, I came up with an analogy for Bitcoin earlier in the year, based on thinking of Bitcoin “unspent transaction outputs” as parcels of land. But in this piece, I’ll skip the analogy and net it down to the basics. When you “move” Bitcoins, what you’re saying is: Fine. Like this:

Sidechains And Lightning, The New New Bitcoin The great thing about Bitcoin, for a tech columnist like me, is that it’s simultaneously over-the-top cinematic and technically dense. Richard Branson recently hosted a “Blockchain Summit” at his private Caribbean island. There’s a Bitcoin Jet. In case you’ve been living in a Faraday cage: a blockchain is a distributed peer-to-peer ledger system, (generally) safeguarded by cryptographic proof-of-work, initially devised by a mysterious entity called Satoshi Nakamoto … who released Bitcoin, the world’s first blockchain network/protocol/application/currency, in 2009. To most people, Bitcoin itself is already deeply esoteric (and many still find it risible.) Sidechains Elements Alpha The distributed Bitcoin mining network performs quadrillions of calculations every second that maintain the integrity of its blockchain. I’ve written about this before. Their “Sidechain Elements” are a collection of blockchain features that go well beyond Bitcoin’s blockchain, including (among others):
Smart Property Smart property is property whose ownership is controlled via the Bitcoin block chain, using contracts. Examples could include physical property such as cars, phones or houses. Smart property also includes non-physical property like shares in a company or access rights to a remote computer. Making property smart allows it to be traded with radically less trust. This reduces fraud, mediation fees and allows trades to take place that otherwise would never have happened. Smart property was first proposed by Nick Szabo in his 1997 paper, "The idea of smart contracts". Background Primitive forms of smart property are already common - if you own a car, it probably comes with an immobilizer. Although these are victories for cryptography, the potential of cryptographically activated property has not been fully explored. Theory This section assumes you are familiar with the Bitcoin protocol, and have a good understanding of contracts. Let's start with the example of a car. Loans and collateral
