the high environmental costs at the end of things because that now that creation transactions consume large amounts of energy plus some predict the sky high sums currently paid for certain items are a bubble waiting to. receive people who understands the concept of earning their true assets more and more i think we'll just see this grow as a generation of people coming generation is going to grow up and they're going to be much more interested in buying something that stage 4 than they are buying something physical. these are still pretty neat schmeichel until they could become a global trend again why do i feel as an investor. and i'm moving on to perhaps more pressing issues what could a covert 900 test have to do with crypto currency or the verification off a vaccination certificate quite a lot actually there are

a lot of instances where this technology that seems abstract to the average consumer is already at play in our everyday life so take a look. the day begins as it does for many of us in germany with a coronavirus test. the pandemic is part of everyday life you need to take a test to go shopping see family or go to work if it's negative you have a sudden if temporary sense of freedom here it is the cover test result negative fortunately but is such a certificate really trustworthy. can such documents be faked yes they can a quick search online soon reveals there's a flourishing market for fake negative test results it's not all that surprising it's easy to scan a test report tweak it with image editing software such as photoshop printed out and write in any name you like another photoshop expert that you and i can do. you

purchase a start up in cologne devoted to ensuring data security and integrity its c.e.o. stefan nala. sent you an email can you open it and we start with a little surprise. you syria negative test result. you could you make it secure absolute can absolutely that's why we've developed our technology in a case like this we would attach a q.r. code to the result is a digital signal of off intensity. you can think of it as a kind of digital notarization as soon as the test comes out of the machine a microsoft ticket is generated and digitally signed by the lab. if you then present the results somewhere else they can all be checked and verified. cuba has worked on the certification of test results in the health care sector using technology from the e.o.

to foundation cryptocurrency developer based in berlin now it's developing a fake proof fisher german vaccination certificate in cooperation with ivy. yota is a readily accessible public block chain that fulfills all requirements. it's been built for precisely the kind of things we do namely the internet of things measurement data and such rather than transactions involving value. it's about the persistence of data. that means the availability of unchanged data over a long period of time. is a co-founder and develop this technology given the little surprise to. very convincing negative. of course he was joking so we will take another at that corona virus test. and just like with block change we verify each other's result. that's been confirmed by both parties trust has been established. as probably the

problem is that i can't trust the systems currently in place. i can't trust this piece of paper because the signature could have been faked. i can't verify that the text is legitimate. or not the same problem exists in the virtual world. the foundation's mission is to make data into digital are trustworthy. and should enable the secure sharing of medical data that was 1st of antiquated by responsible authority or doctor encryption ensures that they can't be tampered with control of the access would be in the hands of the individual. however this only works if the data is actually authentic. as we've seen with photoshop you can easily change a test report on paper. you can also manipulate data in the virtual world.

change a couple of bytes and all of a sudden you have a negative test result even though you in fact tested positive. the aim of our technology is to encrypt and secure data so it can't be changed. and the process of. authenticating and securing sensitive data doesn't sound very exciting but it's incredibly important in health care and in the burgeoning internet of things. now own encrypted currency is turning many people's lives upside down just imagine you own hundreds of millions of dollars worth of bitcoin but then you lose the password to access your account you try everything but every password you enter is wrong eventually axes will be denied for good your money gong sounds like a film script but it really happened and to add insult to injury to

a computer programmer in our last report for today we share the stories off to coin owners and how bitcoin changed their lifes. i got to a point where i was at my absolute and. and i hit rock bottom. and all that corn will replace the euro and other currencies it's the sound choice and stay away from the other crap for now. 'd the value of bitcoin has been rising rapidly for months. and for a long time have made a lot of money entrepreneurs invest as they're being taken most seriously in but then i met a pioneer it's the same the owner of the legendary bitcoin 77 cents 2011 you've been able to pay field bagus and be a hero with a big calling. from your 53 years old and i'm the one who turned this bar into

a big coin holding. this in for me are standing in front of the 1st venue in the world where bitcoin was accepted. to the bar got a certain amount of fame and cult status. coin and when i discovered bitcoin known among bitcoin is as the big coin moment you think my god it's finally here this is it somebody has to do now we've got digital cash. logical to say ok we want to accept this payment here to you and your bitcoin your kind of put up a sign we accept big here. and then back then no one knew what it was there were maybe one or 2 berliners online also interested so i met up with one of them here go and then he paid for his burger and beer and bitcoin and wow that was an incredible feeling. i didn't realize at the time but it was also an historic moment because it was the 1st time that i knew when i would use big money to pay for something physical and a bricks and mortar store. became

a meeting place for big point fans from. another well known 1st generation. he lives in the u.s. but his story is tragic he's also the possibility he's digital big point one it's and can no longer access usenet less of me and. it was it was i didn't know what to do but as a developer and a tech person of course i thought about ways to restore the data there are all kinds of recovery options. i spent the next 2 to 3 weeks 24 hours a day trying out different possibilities even hard disk recovery in the end i realized it probably wasn't going to work. now he has just 2 more possible but attempts ative already been used it's about 7002 big coins. as good doesn't need decisions that are so there's still a chance that i'll get access just have to wait and see. but i'm trying not to get

my hopes up too much so that i'm not devastated later if it doesn't work. i don't think it was random. low points the fact that i had such a low point gave me a lot of motivation and clarity about what i want to achieve in life. to give i take every opportunity to talk about bitcoin you know about financial access to let more people participate in the financial system. i'm grateful for this platform with us and use a platform. yeah it doesn't reveal whether he still i. mean demond is a big point ex-pat already almost number of nice guys who drive lamborghinis but the narrative that i find completely uninteresting to me well that means having enough and that doesn't have to be a cost a little not to be allowed for gaining numbers i don't need to have more than others what's so important with bitcoin it's not that individuals get rich but that

everyone becomes better off today yet i. don't know dozens owns i invest. his by mistake. because as a new system that's what he believes and. i want to own isn't personal responsibility is a huge topic which many understandably also shy away from. because they say a banker has always looked after my money and i was insured and i was supposed to do it myself. and i can understand why people say that's stupid i'm going to be me but other people like me think that's fantastic it's something you should deal with . quite simply that the sooner the better when you feel that if. and that's all for this hopefully not too cryptic cryptocurrency edition of made why don't forget of course you can always comment on all of our stories on one of our social media channels we always look forward to hearing from you in the

meantime from me and the team in berlin thanks for watching stay safe.

play. this is deja vu news life from bernie and yours president joe biden delivers his 1st speech to a joint session of congress he declares america is rising and new threats highlights the progress made against the current barrister and then make and unveil details of a 1.8 trillion touch of families and education also coming up another tragic pandemic record in india the death toll from cover 19 has passed 200000 infection numbers are rising and the crisis is being compounded by shortages of oxygen

medical supplies and hospital staff also coming out. german chancellor angela merkel presses china on human rights and expresses concern over beijing's treatment to tweek a muslim minority and pro-democracy activists. i'm here in the home of 12 to the program joe biden has outlined what he called his blue blueprint to build america and his 1st speech to congress as u.s. president biden discussed his plans to reduce poverty and invest in infrastructure to create jobs. he also stressed the need for the u.s. to reassert its place in the well it's both economically and politically we all know life can knock us down but in america we never ever ever

stay down americans always get up today that's what we're doing america's rising to do choosing hope over fear truth over lies and light over darkness after 100 days of rescue read old america is ready for takeoff in my view we're working again dreamy again discovered again and leading the world again we have shown each other around the world that there's no quit in america non. these all of the scientists joins us from washington d.c. so all of the what did you make of the speech. well certainly a speech of reassurance and all fold and what we really saw there was the joe biden has an agenda and that is strengthening the middle class because this is exactly where his voters are as a whole tonight he spoke about unveiling

a massive family aid plan worth $1.00 trillion us dollars to help those working and middle class families and that is largely funded by tax hikes on wealthy americans so really a sweeping redistribution from the rich to the middle class also he wants to fight climate change and in doing so create new jobs but then we also heard a lot of america 1st. so the policy under donald trump that he'll of course joe biden calls by america now but that in an off itself is the same kind of protectionism that we have already seen in the policies of joe biden's producer now to revise his economic plans biden has a tough task ahead when it comes to winning over the republican party do you think his speech was able to do that that is highly unlikely the case if you took a closer look to the ranks there in the house of representatives republicans were

not applauding simply what biden is laying out there is contrast in republican values so raising taxes for the wealthy if you think back a couple years ago when donald trump took office he copped taxes for the wealthy joe biden now raising the then spending another almost 2 trillion u.s. dollars. certainly not nothing the republicans can support they want a rather slimmer state so they're heavily opposing these measures that we've heard here tonight as they are largely built on debt and turning to a focus to the international stage he said the united states is in competition to win the 21st century but he also said the u.s. needed to work closely with its allies what was that message about. as a what he was trying to paint here is that picture of a struggle of political systems 2 the question of will democracy prevail and certainly looking at china and russia what he's trying to do here is winning

western allies over for a tougher stance on russia and china if you look at europe for instance there is this ongoing dispute between the u.s. and germany over the north stream to pipeline a gas pipeline from russia to germany also a dispute on the economic relations between germany and china germany is certainly not interested in changing any of that because the german position here is that germany's benefiting from its exports u.s. is clearly not doing so because of its trade deficit so we are seeing here some very different interests in different positions when it comes to the future of foreign policy that is one of the sort of speaking to us from washington d.c. thank you all of the. well let's take a look at other stories making headlines around the world former new york mayor rudy giuliani's home and office in manhattan have been raided by u.s. federal agents it's a major escalation of the investigation into his business dealings the oil former

and now she is not really big the body. was ill yesterday in the night it became 6 pm now it is. a long line outside the supply of people doing what they can to save their loved ones some get the oxygen they need. for there isn't enough to go around. saying go home and if someone is dying there then let them they have nothing to do with our pain they have no one in their house who's ill. the state of delhi is reporting one death from covert 19 every 4 minutes and the hospitals can't cope with the growing numbers of patients so the commission grounds are struggling to cope with the rising number of deaths. the funeral pyres a burning day night. delhi is one hotspot of india's covert 1000 emergency maharashtra state in the city of mumbai is another here

china to open its markets even farther that's a key issue for the intergovernmental talks that are being held virtually this time due to the corona restrictions german chancellor angela merkel called for more transparency regarding vaccine production and the reciprocal vaccine approval process and says merkel the contentious topic of human rights should be on the agenda. we've always managed to broach this topic in the past and i'd like to see us get a human rights law going again as soon as possible. but tensions remain the e.u. has accused china of persecuting the muslim minority weekers but what beijing critics are calling reeducation camps the chinese government says are simply vocational schools the body. especially in these intergovernmental talks we have to make clear which values we represent there can be no compromises there we have to

make it clear to beijing that upholding human rights is non-negotiable and if $100.00 buys chinese premier league chang admits to differences but says seamless cooperation is possible if both sides respect the other's core interests and refrain from meddling in internal issues it's a statement that seems to highlight the 2 countries problematic relations. british prime minister bars johnson has denied any wrongdoing after an independent watchdog launched an investigation into how he paid for the renovation of his downing street flats electoral commission says there are reasonable grounds to suspect that an offense has occurred it's the latest in the series of allegations against johnson and his party. this may well have been the most unpleasant day in boris johnson's political career so far and the reason is located in downing street itself his apartment he had it refurbished in this style for about 60000 euros and it's
