What is Blockchain?
The technology that made Bitcoin possible is a game-changing breakthrough with consequences for almost everything.

Blockchain technology.
Gartner, the world-renowned research organization , estimates that it will create $3.1 trillion in new business value by 2030.
Goldman Sachs calls it the “new technology of trust.”
Why is blockchain being talked so much? And what about it is so new and different?
Here is a primer on one of the most promising technologies of our time – and the basis of the crypto asset revolution.
The history of blockchain technology
How did it all begin?
Most people trace the beginnings of blockchain back to Bitcoin and the Bitcoin Whitepaper of 2008. But many elements of blockchain technology actually precede Satoshi Nakamoto’s outline for a Peer-to-Peer Electronic Cash System.
Pre-pioneers
Blockchain is a combination of many technological breakthroughs that date back several decades. Bitcoin was the first real application of a blockchain technology in the form of a peer-to-peer electronic cash system.
In 1991, two scientists named Stuart Haber and W. Scott Stornetta brought out a solution for the time-stamping of digital documents. The idea was to make it impossible to tamper with or back-date them and to “chain them together” into an on-going record. Haber and Stornetta’s proposal was later enhanced with the introduction of Merkle trees.
But time-stamping alone didn’t lead to the birth of blockchain. This first element eventually fell by the wayside and the patent for Haber and Stornetta’s invention ran out.
A second major, missing element was a way to secure the network. Today’s Bitcoin network uses what is called Proof-of-Work to do this. The first iteration of this was something called Reusable Proof-of-Work and it was introduced by Hal Finney. Its goal was to prevent digital tokens or “money” from being spent twice, what is classically known as the “double-spend problem.”
Although Satoshi Nakamoto’s Bitcoin was eventually the innovation that would bring blockchain to the masses, these early pioneers weren’t forgotten. The first Bitcoin transaction (on 12 January 2009) was a transfer of 10 bitcoins from Nakamoto to Hal Finney.
Why is blockchain unique?
So why all the fuss about blockchain? Is it really that important?
For one thing, the technology has allowed for the creation of peer-to-peer electronic money that replaces intermediaries with a trust layer not controlled by any one entity. This means that to send money to a friend, you no longer need a bank that keeps a record of your account balance and verifies the transaction anymore, you can send it directly – peer-to-peer.
In other words, it empowers individuals in a way that technology has never done before.
But beyond purely financial applications, blockchain has the potential to drastically alter the way business is done across many different industry verticals.
A quick example
For a quick comparison, consider Google Docs.
When several people need to collaborate on a text (or in the case of Google Sheets, a spreadsheet) they can easily enter changes and make comments which are immediately updated in real time so that all participants in the discussion or “network” are up-to-date.
Think for a moment about how this has changed the way people do work.
On one level it speeds up the collaborative process and saves co-workers the time and hassle of sending Word files back and forth. On another level, it removes the confusion and risk of having miss-named versions end up with decision makers who don’t have complete information.
Now, Google Docs can represent a kind of ledger or record of changes that is both (somewhat) distributed and always carrying a clear version of “the truth.” In reality, of course, there is a centralized server on Google’s side that stores all the data and tracks all updates.
Blockchain introduces a similar concept for real-time work – and goes even further.
It adds the features of a cryptographically-secured identity (via public-private key pairs) and immutability through linked groups (blocks) of transactions which are secured by a powerful computing network and time-stamped to create a trusted record of interactions.
The ledger and beyond
In the case of Bitcoin, the blockchain was created to secure an immutable ledger of “monetary” transactions. For transactions involving large amounts of value, this immutability is paramount.
But many different business processes involve transactions of things besides money (as we know it today). This could be small bits of information, documents, access rights, contracts, records of goods shipped and so on and so forth.
Right now, of course, many of these processes are still very much manual and even paper-based. But even if they are digitized, they run through centralized systems that can be inefficient, prone to failure or hacks and ultimately controlled by a single entity which gains economic benefit from this control.
Blockchain changes all of that. Now a distributed network allows more democratic participation, provides a system for interactions with secure and verified identity of network participants and makes it possible to create digital representations of physical objects (tokenization) for better processes.
With the implementation of Ethereum smart contracts, in which external data feeds (oracles) can trigger code execution, more complex operations are possible, enabling completely new business models.
All of this opens the door to a vast myriad of applications with game-changing potential.
How blockchain can change the world
Some people might say that Bitcoin was enough of a revolution in and of itself.
But as we explore blockchain’s potential, we see even broader horizons.
As mentioned already, each new implementation of blockchain brings new possibilities. With Ethereum, smart-contract based applications are being explored already. Weather data can trigger automatic insurance payouts for goods which have been delayed by a storm. Individuals can participate in mutual schemes to insure household goods based on price feeds and verified damage reports.
Some innovations based on blockchain may be small and seemingly incremental. With big banks like Santander, this is, perhaps, understandable. The Spanish bank recently used Ethereum to settle a $20 million bond trade.
Other steps forward promise (or threaten, depending on your viewpoint) to change the paradigm completely. Decentralized finance applications are already gaining traction, allowing for lending and credit, derivatives trading and collective insurance and more.
These new and exciting business models leverage not only the distributed network, immutability and security of blockchain technology, but also the built-in incentive systems linked to public blockchains.
What does this mean? Take once again the example of Google Docs.
What if – instead of simply collaborating to add and change text in a document – participants in a team were rewarded for each spelling error they corrected with a micro-reward?
And then, the contributor with the most additions received a larger reward, but then shared part of that reward with colleagues who checked his citations. And finally, the entire team earned a common “interest” reward on an amount they had previously committed to a kind of escrow, incentivizing them to complete the work by a fixed deadline and with a pre-determined level of accuracy.
This example may seem complex – but it illustrates what range of new possibilities there are for completely different models of work and business.

In the Bitcoin network, anyone can join the network and become a bookkeeping service provider i.e., a validator. All validators are allowed in the race to become the block producer for the next block, yet only the first to complete a computationally heavy task will win. This feature is called Proof of Work (PoW).The probability of any single validator to finish the task first is equal to the percentage of the total network computation power, or hash power, the validator has. For instance, a validator with 5% of the total network computation power will have a 5% chance of completing the task first, and therefore becoming the next block producer.Since anyone can join the race, competition is prone to increase. In the early days, Bitcoin mining was mostly done by personal computer *****Us.As of today, Bitcoin validators, or miners, have opted for dedicated and more powerful devices such as machines based on Application-Specific Integrated Circuit ('ASIC').Proof of Work secures the network as block producers must have spent resources external to the network (i.e., money to pay electricity), and can provide proof to other participants that they did so.With various miners competing for block rewards, it becomes difficult for one single malicious party to gain network majority (defined as more than 51% of the network's hash power in the Nakamoto consensus mechanism). The ability to rearrange transactions via 51% attacks indicates another feature of the Nakamoto consensus: the finality of transactions is only probabilistic.Once a block is produced, it is then propagated by the block producer to all other validators to check on the validity of all transactions in that block. The block producer will receive rewards in the network’s native currency (i.e., bitcoin) as all validators approve the block and update their ledgers.bitcoin purse monero spelunker tether обзор bitcoin rotator книга bitcoin

blacktrail bitcoin than block rewards).decred ethereum Over the past few years, there have emerged a number of popular online file storage startups, the most prominent being Dropbox, seeking to allow users to upload a backup of their hard drive and have the service store the backup and allow the user to access it in exchange for a monthly fee. However, at this point the file storage market is at times relatively inefficient; a cursory look at various existing solutions shows that, particularly at the 'uncanny valley' 20-200 GB level at which neither free quotas nor enterprise-level discounts kick in, monthly prices for mainstream file storage costs are such that you are paying for more than the cost of the entire hard drive in a single month. Ethereum contracts can allow for the development of a decentralized file storage ecosystem, where individual users can earn small quantities of money by renting out their own hard drives and unused space can be used to further drive down the costs of file storage.The blockchain is maintained by a peer-to-peer network. The network is a collection of nodes that are interconnected to one another. Nodes are individual computers that take in input and performs a function on them and gives an output. The blockchain uses a special kind of network called 'peer-to-peer network' which partitions its entire workload between participants, who are all equally privileged, called 'peers'. There is no longer one central server, now there are several distributed and decentralized peers.search bitcoin bitcoin client bitcoin комбайн arbitrage cryptocurrency flypool monero bitcoin краны bitcoin trojan bitcoin машина monero fr аналоги bitcoin monero logo 1 ethereum оплата bitcoin

The majority of mainstream economists accept the equation as valid over the long-term, with the caveat being that there’s a lag between changes in money supply or velocity and the resulting price changes, meaning it’s not necessarily true in the short-term.
