The Bitcoin affair: Craig Wright promises extraordinary proof

Craig Wright

The man who has identified himself as the creator of Bitcoin plans to provide further proof of his claim.

Craig Wright's spokesman told the BBC that the Australian would "move a coin from an early block" known to belong to the crypto-currency's inventor "in the coming days".

The entrepreneur announced he was behind the pseudonym Satoshi Nakamoto on Monday.

Critics have said that the evidence produced to date is unconvincing.

In a new blog - published after I first wrote this article - Dr Wright said it was right that the public was sceptical about his claims, but added that he would soon present "extraordinary" evidence to support his case.

Meetings with Satoshi

It was in a conference room above a coffee shop a fifteen minute walk from BBC Broadcasting House that we first met the man who says he is Bitcoin creator Satoshi Nakamoto.

As we walked in, three or four people were waiting around a table - but which one, I wondered, was the father of Bitcoin?

There is a word that you never heard anyone use 20 years ago. But today, according to research from Lancaster University, which examined millions of words of casual conversation, it crops up more frequently than "clever", "eggs", "fridge", or "death". That word is Google.

To search is to Google, to Google is to search.

Rise of the Robots - and Donald Trump

Over the past year we have seen plenty of warnings about the potential impact of robots and artificial intelligence on jobs.

Now one of the leading prophets of this robot revolution has told the BBC he is already seeing another side-effect of automation - the rise of politicians such as Donald Trump and the Democratic presidential hopeful Bernie Sanders.

Powa failure - where did the money go?

Last month I wrote about the collapse of the UK tech "unicorn" Powa Technologies, a firm I called a textbook example of how not to run a business. Back then it was hard to see how Powa had run through so much money so quickly - but now a report from the administrators has provided some clarity.

Deloitte was appointed in February by Powa's main backers Wellington Management after the firm failed to repay the money it owed the Boston-based firm. The administrators have to produce a report which covers the measures they have taken to recover any money for creditors - and what they found out about the state of the business.

Meetings with Amy - and other bots

In more than 30 years in the BBC I have never had a personal assistant, or anyone to help fix my busy schedule (extraordinary, I know). But this week I took on a PA with a specific brief to organise my meetings. She's called Amy Ingram, and I regret to say her work so far leaves a little to be desired. But then again she is a virtual assistant, or bot.

Amy is the product of two years of work by a New York based artificial intelligence start-up called Its co-founder and chief executive Dennis Mortensen tells Tech Tent in an interview for this afternoon's programme that the idea was to prove that artificial intelligence could now handle a single useful task. "We've reached this inflection point where AI can do very specific jobs," he explains. "They can't do everything but if you have one very well-defined job you want done you can give it to the agent and they can do that for you,"

Drone racing - sport of the future?

Media captionDrone races will soon be broadcast on ESPN's TV network

At Wembley last night I experienced what could be the sport of the future. Tiny drones raced out of the players' tunnel and did three laps of the stadium, weaving their way through a slalom course.

The races were hard fought and - according to the commentators - full of thrills and spills.

Amazon Kindle Oasis: Does the world want a £270 e-reader?

It has a good claim to being the most daring and innovative technology company of the last 20 years. It has launched at least two world-changing businesses - an online retailer of breathtaking scale and efficiency and a cloud computing service that has changed the way thousands of businesses work. But why on Earth is Amazon launching another Kindle, and who on Earth is going to pay £270 for it?

That was what came into my head as a group of Amazon executives showed me their latest e-reader this week. I'd come to the warehouse in Hoxton - London's Hipster Central, where Amazon's fashion division is based - on the promise of learning about the tech firm's next giant leap forward. I'd rather hoped to hear that the Echo, a fascinating product which puts a virtual assistant inside a speaker, was coming to the UK.

UK hits broadband target… maybe

Good news on broadband - the UK has hit the target of making a superfast connection available to 90% of homes, as promised back in 2010. But the bad news is that the world has moved on since then, and this achievement won't have anyone cracking open the champagne.

The target was set in 2010 in the early months of the coalition government and came with a pledge that the UK would have "the best superfast broadband in Europe" by 2015. Both aims were later modified as the process of handing over subsidies to BT for rolling out fibre connections in rural areas took longer than expected - 90% by 2015 turned into 95% by 2017 and "best in Europe" turned out to involve a scorecard comparing us on various measures with the larger European countries.

WhatsApp and the backdoor battle

If you've used the messaging app WhatsApp today you should have seen a message saying this: "Messages you send to this chat and calls are secured with end-to-end encryption."

What that means is nobody - not the police, hackers, GCHQ, not even WhatsApp or its owner Facebook - can read the conversations between you and your contacts.
