Why learn Blockchain?
Blockchain is a revolutionary technology. It is an ordered back linked-list data structure of blocks of transactions stored in a decentralized peer- to-peer network. It is the underlying infrastructure for bitcoin, a popular cryptocurrency. In near future, many companies will be adopting blockchain technologies for trading publicly. Apart from bitcoin, it can be used for a wide variety of applications such as tracking ownership, digital assets, physical assets, or voting rights. It can also store and run computer code called ‘smart contracts’. However, blockchain is still new and the communities are still exploring the best ways in which it can be used.

By far one of the BEST BlockChain tutorials on the Tube or anywhere I referred. I am a newbie and as such have few questions, which maybe trivial, from the Demo if you could help me with: 1. When you set up go-etherum in your the Ubuntu box with a genesis block, it meant to be the first block for a brand new chain (means there was no chain before). For a miner to validate and add a block, there needs to be transfers or transactions in the system between accounts. Since this is a blockchain which no one knows about and brand new how come there were transactions which the started miner was mining. Also in a new blockchain how does someone transfer ethers if there arent any as its the very beginning(as minting happens to provide incentives to miners if I understand correctly). 2. Secondly how does the ether generated/minted by this Demo system corresponds or convert to any real world currency like USD. Or what will it take to make these ethers to be sold for actual money. 3. If you kill this Linux box then will the blockchain will cease to exist. 4. How can anybody on the outside transact on this Demo blockchain? Thanks for all your good work! Love it!

What can be the size of the block and what number of transactions can be added in one block?
@edurekaIN
@edurekaIN 6 жыл бұрын
Considering the fact that you are talking about Bitcoin Blockchain, as mentioned in the protocol, the size of the block is 1 MB. The number of transactions that can be included depend upon the miners. In general, miners like bigger fees and smaller transactions and may prioritize them that way. Hope this helps :)

Thanks for watching the video, Sijin. Bitcoin brokers are selling you bitcoins from their reserves, and they need to buy and sell bitcoins to maintain their reserve. So, based on the behavior of the exchanges they use, bitcoin brokers will set a buy price that lets them replace their reserve bitcoins for the same or less than what you paid to buy them.

In the context of AML (Anti-Money Laundering) procedures, there seems to be an opportunity with blockchain transactions/ledgers to both, simplify AND accurately determine who owns what (as well as for more accurate credit monitoring), AND conversely to make it more difficult to do AML as the actual identity of those involved in the transactions are anonymous. How is AML to handle these potential, unscrupulous characters and their shifting capital? Great video, by the way! I learned quite a bit and I also really love that it was instructional as to the 'mining' process. I was just primarily interested in the 'explained/tutorial' portion, but the training was a nice surprise. Thank you!

Its not the vote on the ledger. It's the number of confirmation of a particular block. Also to keep in mind here, the confirmation field is not mentioned in the block. block confirmation" count of a block is simply how many other blocks build on top of that block. Take for example the following three-block-long blockchain. Hope this helps :)

Hi, great tutorial, I am currently going through it and am at 31:00. I need to understand that since the max number of bitcoins that can be generated is capped at 21 million, because of which the blockchain system makes it increasingly difficult to mine the bitcoins, over a period of time, wont the reward proportion be reduced? And if the profit towards mining becomes negative, what will be the incentive for the miners to mine? Moreover, after 2040 (or whenever mining is not financially lucrative), since there will no more bitcoins available, who will act as miners and who will validate the transactions?
@edurekaIN
@edurekaIN 6 жыл бұрын
Hey Chandraneel! Yes the mining reward will reduce over time as the number of miner will increase and so will the value of bitcoins. As the minners will stop making profit from the actual bitcoin reward, they will make money from the transaction fees attached with these transactions. Hope this helps. :)

This votes then will be validated by the government authority by cross-checking the user to their ID and their vote. Once the vote is validated, it gets cast and the total number of votes for each candidate gets updated. If you are interested to know more, you can check out followmyvote.com/ for the complete details on the implementation. Happy learning

How do you add money to your wallet or buy bitcoins to add to your wallet?
@edurekaIN
@edurekaIN 5 жыл бұрын
Hi Yadira, To buy or earn free bitcoins, you first need to download a bitcoin wallet, which is software that allows you to securely send, receive, and store funds in the bitcoin network. And, then use websites like Coin ATM Radar to help you find a Bitcoin ATM, which works very similarly to a regular ATM, except you trade your cash for bitcoin. But make sure you do more research on this before transferring money.

As it is decentralised.. Where the ledger will be saved? .
@ryanshannon7703
@ryanshannon7703 6 жыл бұрын
Among the 'Ledger holders' being validated by the 'blockchain miners', as there are multiple 'ledgers' that are kept within the system. Think of it as a public ledger where multiple entities have open access to it. This is explained around the 20 to 24 minutes mark. There are variations of blockchain systems that handle transactions as validation differently, but still utilize the same fundamental idea. I believe Etherium uses a slightly different approach for greater transaction volume.

You have mentioned that mining involves lot of Mathematical Problems to solve , but what I understood is only miner.start() and miner.stop() , its a matter of just giving computing power is that so? Well my understanding is this please let me know about this
@edurekaIN
@edurekaIN 6 жыл бұрын
miner.start() and miner.stop() is only on the test environment where no computational power is required(obviously because you are the one who is doing the transaction and it is correct).It is only to show that how mining happens in the actual environment.In the real time environment a lot of transaction is happening and mining is done to verify the records for that we need high computational power. Hope this helps :)

how much incentives expected for miner for creating a blockchain
@edurekaIN
@edurekaIN 5 жыл бұрын
Hey Ram, sorry for the delay. Firstly, miners don't create blockchain. They are the key participants of the blockchain network who are incentive's for verifying and validating transactions across the network.As of now miners receives 12.5 BTC for mining a block plus the transaction fee associated with each transaction that are included in the block. Hope this helps!

Hey Manav, Firstly, you need to understand that everybody participating in the network has a chance at validating a block. So by semantic logic everybody can validate. But, some people have invested in high performance GPU's to have a better chance at validating blocks by solving the prrof of work.

In 2016, ICICI Bank announced that it had completed a cross-broder transaction via BlockChain. You can either look for a job in this sector or look for starting up something on your own with currency mining or trading in these currencies.

Hey Naveen, Yes this does lead in a delay but when banks implement the blockchain as part of the environment, the customize it in a manner where there is no need for a miner to validate the transactions.

There is no passing law that makes bitcoin and other crypto currencies illegal. The major issue here is that our money is regulated, managed and maintained by banks. In crypto-currencies, banks have nothing to do with it. Therefore, they are not regulated by a central authority (like banks). This is a major game changer as banks have complete monopoly over all our monetary property. Since, it is unregulated people involved in bitocoin have to be very careful about everything they do with it.

Hey Amit, In order for a group for a group of hackers to manipulate the Blockchain, they need to have access to more than 51% of the resources. Let's say a public Blockchain is running on 100 system, the hackers need to gain access to at least 51 of these systems in order to completely manipulate the Blockchain network. Since the current Bitcoin Blockchain is using resources across the globe, it is not possible for a group of hackers to gain 51% majority to manipulate the Blockchain. Hope this helps!

why cannot a miner edit the transaction details as he/she is the one who validates the transaction?
@edurekaIN
@edurekaIN 5 жыл бұрын
Hey Puneet, sorry for the delay. For a transaction to be validated, at least 51% of the network nodes should accept that transaction. If a miner changes the data then other nodes in the network will reject the transaction and hence the changes made by the miner will not be in effect. But if 51% of the nodes in the network agree on a fake transaction then the data can be changed. Hope this helps!
