Andy Murray ‘eternally grateful’ to Ivan Lendl after mutual split

Blockchain is a form of distributed ledger technology, a digital system in which data is recorded across multiple places at the same time. Unlike traditional databases, DLTs have no central administrator or centralised data storage. They are transparent because the data is visible and, because they are automatically replicated and impossible to be tampered with, they are secure.

The main difference between blockchain and other forms of DLT is the way data is stored as ‘blocks’ – new transactions are added to the existing ‘chain’ of past transactions, hence the name ‘blockchain’. It is impossible to delete or modify information on the chain due to the replication of blocks across various locations.

Blockchain is mostly associated with cryptocurrency Bitcoin. Due to the inability to tamper with transactions, advocates say this makes the currency more secure and safer than traditional systems. It is maintained by a network of people referred to as ‘miners’, who receive rewards for solving complex mathematical equations that enable transactions to go through.

However, one of the major problems that has come to light has been the presence of illicit material buried in the Bitcoin blockchain, linking it to the dark web.

Other blockchain platforms can offer things like smart contracts, which are automatically implemented when specific conditions from all interested parties are reached, cutting the time involved and the risk of mistakes. Another use could be storing medical records, as patients can be confident their information cannot be changed. The technology can also be used in supply chains, voting and has the potential to used for storing property records.

The verdict from the nutritionists is damning. But does a cheesecake frappuccino taste good enough to merit the indulgence?

My advice is to only go there if you have unusually sweet tooth. I like my puddings, but this was a bit much even for me. The first hit is a winner, but it's downhill, slowly, from there. Each sip is a little less satisfying than the last, and maybe it was just all that sugar, but it isn't long before the rush is replaced by a creeping remorse. And half of the thing is still left.

The caramel version is far superior to the blueberry, too. If someone put a full caramel cheesecake through a liquidiser and scooped out the contents, it would probably taste something like this. Blueberry, on the other hand, has more of an artificial taste. It's like someone has tried to invent this drink in a lab, and while early results were promising, they're still in the testing phase. It isn't terrible, but something isn't quite right either.

So if you want an experience, go for a small, and opt for the caramel. But if you want a cheesecake, it's probably more satisfying, and not quite as unhealthy, to just order the real thing.
