As the implications of the invention of have become understood, a certain hype has sprung up around blockchain technology.
This is, perhaps, because it is so easy to imagine high-level use cases. But, the technology has also been closely examined: millions of dollars have been spent researching blockchain technology over the past few years, and numerous tests for whether or not blockchain technology is appropriate in various scenarios have been conducted.
Blockchain technology offers new tools for authentication and authorization in the digital world that preclude the need for many centralized administrators. As a result, it enables the creation of new digital relationships.
By formalizing and securing new digital relationships, the blockchain revolution is posed to create the backbone of a layer of the internet for transactions and interactions of value (often called the ‘Internet of Value’, as opposed to the ‘Internet of Information’ which uses the client-server, accounts and master copy databases we’ve been using for over the past 20 years.)
But, with all the talk of building the digital backbone of a new transactional layer to the internet, sometimes blockchains, private cryptographic keys and cryptocurrencies are simply not the right way to go.
Many groups have created flowcharts to help a person or entity decide between a blockchain or master copy, client-server database. The following factors are a distillation of much of what has been previously done:
Is the data dynamic with an auditable history?
Paper can be hard to counterfeit because of the complexity of physical seals or appearances. Like etching something in stone, paper documents have certain permanence.
But, if the data is in constant flux, if it is transactions occurring regularly and frequently, then paper as a medium may not be able to keep up the system of record. Manual data entry also has human limitations.
So, if the data and its history are important to the digital relationships they are helping to establish, then blockchains offer a flexible capacity by enabling many parties to write new entries into a system of record that is also held by many custodians.
Should or can the data be controlled by a central authority?
There remain many reasons why a third party should be in charge of some authentications and authorizations. There are times when third-party control is totally appropriate and desirable. If privacy of the data is the most important consideration, there are ways to secure data by not even connecting it to a network.
But if existing IT infrastructure featuring accounts and log-ins is not sufficient for the security of digital identity, then the problem might be solved by blockchain technology.
As Satoshi Nakamoto wrote in his (or her) seminal work, “Bitcoin: A Peer-to-Peer Electronic Cash System”: “Merchants must be wary of their customers, hassling them for more information than they would otherwise need. A certain percentage of fraud is accepted as unavoidable.”
Private key cryptography enables push transactions, which don’t require centralized systems and the elaborate accounts used to establish digital relationships. If this database requires millions of dollars to secure lightweight financial transactions, then there’s a chance blockchains are the solution.
Is the speed of the transaction the most important consideration?
Does this database require high-performance millisecond transactions? (There is more on this point in our guide: “What is the Difference Between a Blockchain and a Database?”).
If high performance, millisecond transactions are what is required, then it’s best to stick with a traditional-model centralized system. Blockchains as databases are slow and there is a cost to storing the data – the processing (or ‘mining’) of every block in a chain. Centralized data systems based on the client-server model are faster and less expensive… for now.
In short, while we still don’t know the full limits and possibilities of blockchains, we can at least say the use cases which have passed inspection have all been about managing and securing digital relationships as part of a system of record.
Lee said in March 2017 that this transition partly explains his creation's success: litecoin 'got lucky where, when bitcoin mining went from GPUs to ASIC, all the bitcoin GPUs were looking for a coin to mine, and litecoin just happened to have transitioned from CPU to GPU at that time.' Soon enough, however, ASICs were developed for Scrypt, and today it would be difficult if not impossible to turn a profit using anything but ASICs. One popular ASIC for Scrypt mining is Bitmain's Antminer L3+, but batches tend to sell out almost immediately, meaning you have to watch Twitter like a hawk; the company only accepts bitcoin cash and USD wire transfers (for some batches it only takes the former). Innosilicon is accepting pre-orders for a competitor, the A4+ LTCMaster. Other options are available, but the newest ASICs tend to run at least $2,000 and sell out quickly. Older ASICs may not be competitive, making it hard to turn a profit.The energy it will consumeBlockchain is capable of making the voting process easy, efficient, and secure. It negates the chance of election fraud as each vote will be given a unique ID. Governments can improve the efficiency of tax collection and filing processes by taking advantage of blockchain. Furthermore, this technology opens the door to better regulatory oversight on businesses and organizations, allowing prior detection of red flags and lack of compliance.

Either and each are secured and validated by the same mechanism and by the same rules. Everyone has equal rights. Regardless of the economic value, each bitcoin (and bitcoin address) is treated identically within the bitcoin network. If a valid signature is produced, the transaction is valid and it will be added to the blockchain (if a transaction fee is paid). If an invalid signature is produced, the network will reject it as invalid. It does not matter how powerful or how weak any particular participant may be. Bitcoin is apolitical. All it validates is keys and signatures. Someone with more bitcoin may be able to pay a higher fee to have a transaction prioritized, but all transactions are validated based on the same set of consensus rules. Miners prioritize transactions based on value and profitability, nothing else. If a transaction is equally valuable, it will be prioritized based on a time sequence. But importantly, the mining function, which clears transactions, is divorced from ownership. Bitcoin is not a democracy; ownership is controlled by keys and every bitcoin transaction is evaluated based on the same criteria within the network. It is either valid or it is not. And every bitcoin must have originated within a block consistent with the 21 million supply schedule in order to be valid.It’s for everyone: Cryptocurrencies are open to every person on the planet.

If Friend A guesses 21, they lose because of 21>19. If Friend B guesses 16 and Friend C guesses 12, then they've both theoretically arrived at viable answers, because of 16<19 and 12<19. There is no 'extra credit' for Friend B, even though B's answer was closer to the target answer of 19. Now imagine that I pose the 'guess what number I'm thinking of' question, but I'm not asking just three friends, and I'm not thinking of a number between 1 and 100. Rather, I'm asking millions of would-be miners and I'm thinking of a 64-digit hexadecimal number. Now you see that it's going to be extremely hard to guess the right answer.bitcoin crush Cryptocurrencies make tracking donations easier and have the potential to allow donors to see how their money is used (financial transparency).вики bitcoin
