HK Blockchain Week 2020 - Keynote Speech by Roberto Capodieci (CEO, Blockchain Zoo)

When a blockchain has no points. Here comes the need to the kobold blocked me from cryptocurrencies for GolfTEC, GolfTEC and this is not just me improvising, and this is exactly what Roberto couple of the edgy, the CEO of blockchain zoo is going to tell you about just a few and I am the CEO of a block pencil. Would like to talk to you about today is the adoption of blockchain outside. The the use of cryptocurrencies and there is born as to make Bitcoin possible. But the

government, the one product blockchain need the blockchain to be separated the from cryptocurrency. In the two separate blockchain from cryptocurrency with the basis that the blockchain as today 7 Alicia. if you think about the way that aspect, Bitcoin is secure because of the value of the currency compared to the cost of a 50% of that renting enough power to attack. A blockchain based on proof of work is directly proportional to their market cap of the currency of that

blockchain. We saw that the wide Bitcoin remain quite solid and very expensive to attack mine or proof of our blockchain such as if you don't classic got attacked several times 51% and 51% of tigers that attack where I can rent enough ice power to be able to rebuild a huge chunk of blocks over the last block without the is on transaction. Is there a way to double spend money in a blockchain? And that old security boys, down in the cost of such a tax compared to the economy of the total value of the coins of the blockchain?

And I'm still kind of a protocol is proof of stake and stake. It means the amount of coin that the same account in order to have the authority to create blocks the basis of a proof of stake and blockchain. Security is the fact that to make an attacker to the block Shane the cost of staking enough coins, make it so that it will only damage that attacker and not much that I still the economy because 12 tap the blocks I need to own the majority of the economy of the blocks in itself. So one more time is on the

cost of that that compared to the value of the coin in the blockchain. The moment a blockchain is used for different use cases. For example, the management over medical record rather than the transfer of title of ownership of real estate or Delta reservation for leaves of employees, rather than grades for the school for students or many of us kids. If they don't have it, direct connection to a currency in the blockchain or shoot me a higher value of the currency of the blockchain

work, at the handle grades for students who are the currencies used gesture to To have it there because his dad in the blockchain that is being thrown to make this project. Well, it won't take very little for smart students. That got a bad grade probably 9 mathematics, but in history or geography, verse a to get dinner for ash power in the river. I said the last part of the blockchain removing the bed radio station. As much as you for a blockchain is handling titles like the ownership of real estate complex that is worth billions of dollars and the title. It's a

silicone ice as we go by the government. Once somebody make the sales and received the payment, then can easily attacked the blockchain and removing the transfer of the title that is being recorded in the blockchain, and their property remains is on property, neither of a different circumstances mechanics is. So it's not just a matter of a government. GolfTEC read text to adopt blockchain. Genital the method of Block Chain has a mechanic. So security, there is no connected to finance. The value of the coin of the

blockchain. For this reason, we have implemented the Brookfield Zoo but there is a natural evolution of love. Saying that the me to happen and we are happy to open conversation with many, or this year, is having a blockchain. Who is that consensus is basing, its security, not on a coin, but something else. So now is more parentheses to understand what is the consensus McDonald's in a blockchain. Well as we know how blockchain is a decentralized system, which means

that there are many notes possibly run by the different parties that are taking advantage by using the blockchain itself known of Pisa computer. The make the night worker is more important than the others is very important to cold in the South a logical choice in front of a possibility of two different. Why is the word consensus that? Give us the idea of people coming together talking and a green on the common out camera on a common decision. In the temple Sciences, is deeply different.

The notes don't come together to sit and discuss it and make a decision, then nothing Factor. Don't ask any other noteworthy, think about an option for a choice, but they make a choice based on how they been coded. So if somebody can trigger the softer of the know they making the decision, that is correct, the base of the code but is brown base. On the desire of the choice is hacking is attacking the blockchain. For example of 51% of doctor in a proof of the blockchain

tricks, the node to believe that the temper blockchain is a more solid, more important so that don't they know the ball. Drop that block, Shane the adults in the one provided by the doctor and this is the base pretty much over every Spawn a blockchain preparing. It's always said that the new things is better than the choice that they already know. So the security that is made the ornata block. Shane, the defendant financer is usually based on their finances back. What we need is a blockchain with the security in the consensus. Mechanics is so way for the note to choose which is a better

blockchain is not related to anything. Financial or anything related to a coin in the blockchain. So what we have created them what they needed. The next step in the evolution of a blockchain. Is it who sang Sushi? The days, is it Security on the participation of the nodes in the blockchain? So evaluate I don't know, it's behave in the night worker and give the score on the noses for being there, for the blockchain for up, keeping the block saying, if we keep in the blockchain solid

and Safe in His Way, didn't olds have a certain score and their decision has a weight. That is a more or less important. They organise themselves to the consensus mechanics in such a way that The Inferno, the cheat and get out of this mechanic is poolish the score that Lord & Taylor's kicked out. So let's pretend the Consortium of hospital. For example, for a government situation, where is Providence a city Ransom note to contain a set of information that they need to be sure

that is correct. The when these exchanges between one of the other party Call Simply to be part of the nitrogen, the nursery secured by a mechanic. So, for this reason to study move the from group of workers, prefer proof of a capacity, proof of and there are many different proof to approve of participation accountability and the decentralized in management over the information in the doctor because he and that they are in need of a system to keep data stable. So think about this time,

he's all about the blockchain but the we need to think of all the technology is going to evolve. How is technology is going to go to the next step before the large adoption? Outside the decentralized finance outside all day. I c o r e o and all those things that are there to satisfy the requirements of the party. The one third of the need to adapt to avoid in the information. In this next stage, that is the decentralization. I always say, we are in the early

days of a blockchain. As a technology is like it. When cars, the first invented, somebody need to spin the things in front of an order to start the engine and that was never mind. If we look at the use of the fuel or electric literally hundreds of years and years, since the first God has been produced. So, Is true that there is a lot of money. The people is happy to make it when they followed his hives, all over ice, your Defiance on and so forth. But the technology need answered as well that they evolved in this technology from the bottom app.

What are more easily take a blockchain, the use coins, or to do a solution that has no need of coins. We always fall into the financial regulation and they will later they're going to step in and make the process are there. Many people think the blockchain is cryptocurrency. Real Change Is Now crypto currency is like to say that database is our fault them for that, Arista or the debate matchmaking, or a dead. Did the engine behind the lot of illegal things, which can be, but this is just a tool, is just a technology. So this is for, this is the case

of blockchain routine is not cryptocurrency. It can be used for cryptocurrency but blockchain is a technology that can be adopted in user to ratna many different kind of a business. Let's think how many use cases don't need to really coins in a blockchain to function properly, but the blockchain is really the technology they need. They think about International Trade, stink about business management partnership franchises in the world. Document management, agreement signature old, the legal aspect of a documentation between different country between different

parties, to resolve the issue tracker, and all the accused cases that are connected to the paperwork or title title of ownership. Are you the government to put mayonnaise on the blockchain, the police officer? Give us a fine which is recorded on the Block, is the title of the car, the licensure, and so on and so forth. In the consensus mechanic is just the tip of the iceberg blockchain added me to survey, use cases, where the cryptocurrencies node are, they required to provide a lot of older functionality. For example, allow a third party to approve or disapprove a transaxle. The same

purchasing a car and there is a notary or a government employee of the office of records of cars that approve, the transfer of ownership and they can be something as we actually did this thing with great satisfaction to sign transaction on the blockchain with the meid. So their identity cards and now we're coming with a capacity to digitally sign to sign with the private key, private key to sign x to the card blockchain transaction transaction, for example, closing the contractor

for rent. Is valid in Portobello in case one of the party doesn't pay. So I leave you with this listing, Cerf to the evolution of blockchain, they stink at to the technology and I'll just do the high. But that the maids a lot of us broke or rates based on the lack of the, we have thank you very much and that you can come have a chat with us to our boot blocks and zoo. And that's okay with us about our technology to BC.
