the headlines... a third case of the new omicron variant of coronavirus has been detected in the uk — the government urges people to get their boosters and to follow new rules — from tuesday on mask wearing in england. the government says pupils in year seven and above in england should wear masks in communal areas of schools from tomorrow morning. the south african president has criticised the decision to put the country on the international red list. tens of thousands of homes and businesses are still without electricity — in the wake of storm arwen. four european countries agree to deploy a plane to patrol the french coast — to help prevent migrants crossing the sea to britain. and sir frank williams — who created one the great formula one teams — has died aged 79. coming up in a moment on bbc news it's sportsday — but first, here's click. are you ready for today's teaser? go on, then! right, what does this penguin, this building in iceland, a huge digital artwork and this slamming basketball block all have in common? ah, our most loyal viewers might know! yes, they will. they've all turned up in our attempts to explain the blockchain — the buzzword of the decade, the thing that every business needs. does it really? no, but go with me. and the thing that's currently burning through more electricity than the country of argentina as people use blockchain technology to try and get rich on cryptocurrency. so, the blockchain is a way of storing ownership records. it can prove that you own a bitcoin, a house or even a video clip. that proof is a unique token that is non—changeable, non—fungible — it's a non—fungible token, or nft. personally, i've always been sceptical of whether nfts are a sensible idea, but there are plenty of people who've bought into them, literally. ownership rights for some digital artworks have gone for millions of dollars, and collins dictionary has just made nft its word of the year. and just last week, a new development — a group of people got together and tried to crowdfund enough money to buy a printed copy of the us constitution at auction. they were outbid despite claiming to raise $40 million. but had they been successful, each of the thousands of contributors would've had the right to vote on what happened to the historic document next. so they could vote to put it on public display. oooh! they could vote to sell it on, or anything in between. yes, and whatever they voted to do would have been handled by a decentralised autonomous organisation - a dao. but what on earth does that mean? a dao is similar in some ways to some of these financial flash mobs or crowdsourcing activities, where you get a bunch of people coming together, they put some money into something to buy an asset. the difference is that in one of those activities, there are people who are recognise — recognisably running the show and are in charge of thinking it through. in a dao, we are defining it all upfront and then we're letting it run its own course. and this idea can be used for anything. a group of people have got together on the internet to raise funds for a dao to buy this area of woodland in wiltshire, in the south of england, and they can decide how it's managed. so a dao is a way of setting up an organisation that is — that uses the blockchain to sort of manage membership and let people organise around a particular cause or project. the treedao is this project to buy a woodland and then let the local community sort of take control of that woodland and vote on what happens to it, using the blockchain, using smart contracts. smart contracts, they sort of run automatically, so instead of having to appoint a treasurer and a secretary, people can use their membership tokens to vote on things. it's about being able to determine that you hold a vote in the governance of the forest, so you can determine, you know, what's allowed to happen here and you can vote on, you know, making sure it doesn't get turned into firewood. i've been fascinated by the technology and how daos is a new way of organising people around projects and i really wanted to see what you could do in terms of — like, there are daos that, you know, just live on the blockchain and don't interface with the real world, and i really wanted to see what you could do, whether a dao could own a real—world asset like a forest, and so this was sort of an experiment to see how this sort of new blockchain technology could interface with the real world. and i was just very lucky that, you know, i sent out a tweet on monday morning and we'd raised 100 f — which at the time was about £100,000 — by thursday morning, and then we had to go and find a forest to buy, so we actually raised the money before we — before we started looking for a forest. yeah, a dao could be used for — for anything. it could be used for organising around a particular cause, or you could buy a football team or you could use it to advocate for a particular change in the law. it — like, i think daos are gonna be a new way of people organising for sort of any — any reason, really. anyone can buy into the forest by purchasing an nft. it'll come with the gps co—ordinates of an exact spot in the woodland. but if people who live locally buy in, it also means that they have a say in an area that they use and love. i mean, one of the — one of the joys of the internet has always been that you can raise your hand and find people like you, wherever they are in the world. you know, tisbury�*s catchment area's like 6,000 people. the advantage of this is that we can reach to anybody as far as you like who wants to protect woodlands. yeah, as you walk around the, you know, the woodland, as an owner, you know, it — it's subtle, but a really important, you know, feeling. like, it feels like it's ours and i think the exciting thing is we can now bring that sense of �*ourness' to other people — anyone who becomes an nftree holder. we've been waiting for this for 20 years and, you know, here it is. like everything to do with crypto and blockchain, there is a huge buyer beware to getting involved. some initiatives are legitimate, but others are scams, and sometimes, it can be very hard to tell the difference. treedao says that what it's doing shows how this new way of running things could be used responsibly and effectively. but it's early days for these ideas, so what daos really end up being used for could surprise us all. now, do you remember yourfirst mobile phone? oh, the nostalgia and the battery life! well, now, over 2,000 old models have been put in a mobile phone museum for safekeeping. and although it is generally an online venue, chris fox went to its glitzy london launch this week. i'm here at the launch of the mobile phone museum in london, a collection of more than 2,000 unique mobile phones from history, and i'm here with the curator, ben wood. you're gonna to take me down a little trip on memory lane. i'd love to show you all 2,120 phones, but what we're gonna do today is pick a few out, and we've got some collections that we've curated for the museum tonight, and the first one is what we consider one of the ugliest phones in the collection. oh, ok! wow. whoever designed this will be upset! oh, not this! laughs now, i think i knew people at school who had this and it looks very cool, but just totally impractical to text on. so this is the nokia 7600. it was nokia's first commercial 36 phone and, as you said, it was at the time when texting was very popular and i guess there was an idea that you could text using your thumbs down the side, but it was counter—intuitive. but look at it — i mean, it's not really a thing of beauty. other phones in the ugly collection include the ntt personal, which won a design award back in 1995, but due to its shape is now known as �*the toilet seat phone'. and this is the i—kid's sf from 2006, which has rabbit ears to make it appeal to children. 0h! gasps wait, is this...? is this from tomorrow never dies? it is! ah! i love this! and this must open up into... gasps i remember this — you can drag yourfinger across and drive the car. also, we have the fingerprint scanner here, so you may remember in the film that was done. also, there was a magical screwdriver that you could use to open a safe. does it also do the, "recall, three, send"? the piece de resistance, which is very difficult to make in a model... yeah! the taser! both laugh other movie phones in the collection include the nokia 8110 banana phone from the matrix, nokia's first slider phone. the version in the movie was spring—loaded but the real one, you had to open by hand. and this white sony ericsson is another bond phone — this one owned by vesper lynd in casino royale. i want to show you a phone which was the phone which the first mobile phone call in the uk was made on. this is the vodafone vt1. a phone call was made onjanuary 1, 1985. so the numbers are on here... yep! ..and then you... hello? just check out the weight. oh — oh, wow, ok. so where do i put the apps? oh, you might struggle with the apps on that one! this was my favourite category because there were so many world firsts, like the ibm simon, blending computer—style features with a phone. it's widely considered one of the first smartphones of a sort — although it wasn't branded as one in 1993. sharp's j—phone from the year 2000 is considered by the museum to be the first full—camera phone. terribly low resolution by today's standards, but it sold out in two weeks injapan. it had a mirror on the back for taking selfies. first android looked very different from today's phones with a full physical keyboard, but in many ways, the first iphone doesn't look that different from today's devices. and this was the first pocketable phone from 1986, at a time when mobiles were typically still bricks. its designer, nils martensson, was one of the special guests i met at the museum. we had commissioned stanford research in america to forecast how many cellular telephones there would be in america year 2000. and they came back with the expensive report and said, "we think that there may be as many as 30,000 in america "by year 2000." and i think had they said 30 million, they would have been a little off the mark, even with that figure. everyone�*s going to know this one. we're on bestsellers. is it going to be the 3310? let's see. there it is, yep. old and trusty. trusty and hardy. 3310. controversial — i actually think the 3210 looks better. that's the one i had and i never upgraded because i thought the other one looked — like, this looked cheapersomehow, but... but a phenomenal commercial success — 126 million phones sold, the equivalent of the japanese population. every single person would have one. it's iconic. and do you know what? it's the one phone, when i take it to the museum and show people, everyone knows the 3310. and that's it for the short version of the programme. the full—length show can be found on iplayer. and throughout the week, you can keep up with the team on social media. find us on youtube, instagram, facebook and twitter — @bbcclick. thanks for watching. bye—bye. hello and welcome to sportsday — i'm holly hamilton. coming up on tonight's programme. one of formula one�*s most influentialfigures, sir frank williams, dies at the age of 79. we look back at his remarkable life. the battle at the bridge. jadon sancho gets his first goal premier league goal as manchester united cling on to take a point at chelsea. and they didn't make life easy for themselves — but great britain are through to the davis cup quarterfinals. good evening and welcome to tonight's programme. we start with tributes to a formula one legend, one of the most successful team owners in history — sir frank williams — who has died at the age of 79. founder and former team principal of williams racing, his team won nine constructors�* championships and seven drivers�* titles and is often described as one of the sports most infuential figures. lizzie greenwood hughes looks back at his remarkable life. in a sport so dominated by global big business, frank williams made formula 1 a family affair. the former salesman was a pioneer, building up his motor racing team from nothing, starting in an empty carpet warehouse in oxfordshire and going on to become the best in the world. seven wins for frank williams�* team. up to the chequered flag and passed it goes alanjones. i have had a wonderful life, i wouldn't change anything, truthfully. an exciting business with something to worry about. which can be quite healthy, actually. it's been very good to me. in total, a williams racing won nine constructors world titles and seven drivers titles. mansell finishes and he is world champion.
