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.

bitcoin check bitcoin википедия This idea of a ledger is the starting point for understanding bitcoin. It is a place to record all transactions that happen in the system, and it is open to and trusted by all system participants. Bitcoin converts this system for recording payments into a currency. Whereas in banking, an account balance represents cash that can be demanded from the bank, what does a unit of bitcoin represent?

The higher the difficulty rate, the less likely that an individual miner is to successfully be able to solve the hash problem and earn bitcoin. In recent years, the mining difficulty rate has skyrocketed. When bitcoin was first launched, the difficulty was 1. As of May 2020, it is more than 16 trillion.34 This provides an idea of just how many times more difficult it is to mine for bitcoin now than it was a decade ago.bitcoin взлом автокран bitcoin

If there’s anything I hope to communicate with this post, it’s that design features of Bitcoin that appear odd, ugly, or broken tend to have good justifications beneath the surface. This doesn’t make them unimpeachable: there is certainly a case to be made for the alternatives, and that design space is being actively explored by thousands of projects.paypal bitcoin trezor bitcoin bitcoin trade bitcoin mmgp bitcoin club bitcoin обменник алгоритм bitcoin метрополис ethereum bitcoin начало bitcoin word ethereum упал space bitcoin форк ethereum bloomberg bitcoin bitcoin автоматический бесплатный bitcoin payoneer bitcoin 'Bitcoin 2'кран monero

total cryptocurrency bitcoin trading arbitrage bitcoin tether обзор bitcoin gif bitcoin x2 Monetary commodities have high stock-to-flow ratios, which refers to the ratio between the amount of that commodity that is stored (aka 'the stock') and the amount of that commodity that is newly-produced each year (aka 'the flow').asics bitcoin In all perceived-to-be successful applications today, money is issued by a central bank; it is relatively stable and capable of near infinite transaction throughput; it facilitates day-to-day commerce; and by the grace of god, its supply can be rapidly inflated to meet the needs of an ever-changing economy. Bitcoin has none of these traits (some not presently, others not ever), and as a result, it is most often dismissed as not meeting the standards of modern-day money. This is where overthinking a problem can cripple the highest of IQs. Pattern recognition fails because the game fundamentally changed, but the players do not yet realize it. It is akin to getting lost in the weeds or failing to see the forest through the trees. Bitcoin is finitely scarce, it is highly divisible and it is capable of being sent over a communication channel (and on a permissionless basis). There will only ever be 21 million bitcoin. Rocket scientists and the most revered investors of our time could look at this equation relative to other applications in the market and be confounded, not seeing its value. While at the same time, if posed with a very simple question, would you rather be paid either in a currency with a fixed supply that cannot be manipulated or in a currency that is subject to persistent, systemic and significant debasement, an overwhelming majority of individuals would choose the former all day, every day.bitcoin bcc эфириум ethereum bank cryptocurrency
