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.

Far from helping 'trusted' institutions, it is an effort to organize economic activity without the need for such intermediaries, who have been shown in recent history to ***** authority. Further, we will show that digital currency systems developed for-profit are inferior to free and open source systems like Bitcoin, and that if successful, systems like Bitcoin benefit small and medium businesses and undermine large enterprises.Enter the cost of your electricity in kWh.

Bitcoin is finding more and more niches for early adoption, which further supports its market price, providing confidence to holders that it will retain value, and this further lends Bitcoin to be used for still more purposes. It’s an organic and messy process, full of trial and error, potholes, brilliant innovations and terrible failures. But that’s what an open marketplace is, no? Every day a more resilient economy is being built, and not at the point of a gun, but voluntarily — not by decree of Bernanke, but by spontaneous, self-interested private order.статистика ethereum mooning bitcoin yota tether 0 bitcoin bitcoin pool bitcoin conf проект bitcoin bitcoin machine форумы bitcoin bitcoin конвертер bitcoin казино bitcoin алгоритм ethereum habrahabr tracker bitcoin bitcoin значок visa bitcoin github ethereum доходность ethereum андроид bitcoin shot bitcoin bitcoin софт delphi bitcoin bitcoin руб cryptocurrency charts bitcoin banking bitcoin мерчант bitcoin bitrix bitcoin knots elysium bitcoin avatrade bitcoin uk bitcoin карты bitcoin bitcoin fasttech blogspot bitcoin bitcoin froggy bitcoin cny bitcoin государство bitcoin 10 bitcoin crash ethereum pos express bitcoin bitcoin bounty bitcoin вклады script bitcoin bye bitcoin bitcoin value bitcoin converter ethereum chaindata monero difficulty ethereum zcash tether криптовалюта bitcoin блокчейн ethereum логотип rotator bitcoin ферма bitcoin аналоги bitcoin лото bitcoin

The Bitcoin currency had to be worth something before it could bear any amount of real-world payment volume. This is the classic 'chicken and egg' problem with new technology: new technology is not worth much until it’s worth a lot. And so the fact that Bitcoin has risen in value in part because of speculation is making the reality of its usefulness arrive much faster than it would have otherwise.bitcoin мерчант How do you store cryptocurrency?тинькофф bitcoin инструкция bitcoin KEY TAKEAWAYSbitcoin girls 1HistoryThe goods cannot be transported easily, unlike our modern currency, which fits in a wallet or is stored on a mobile phone.pos ethereum ico bitcoin bitcoin darkcoin simple bitcoin

Venezuela isn’t the only place where people can use Bitcoin as an escape valve. In Zimbabwe, Robert Mugabe printed endless amounts of cash and inflated the savings of his citizens into nothing, but his successors can’t print more bitcoin. In China, Xi Jinping can track all of your transactions on Alipay and WePay, but he cannot orchestrate mass surveillance on all Bitcoin payments. In Russia, Vladimir Putin can target an NGO and freeze its bank account, but he can’t freeze its Bitcoin wallet. In a refugee camp, you might not be able to access a bank, but as long as you can find an Internet connection, you can receive bitcoin, without asking permission and without having to prove your identity.bitcoin китай monero hashrate счет bitcoin что bitcoin

Blockchains themselves do not have the ability to connect to outside applications in a trusted manner. Chainlink’s decentralized oracles allow smart contracts to communicate with outside data so that the contracts can be executed based on data that Ethereum itself cannot connect to. faucet ethereum bitcoin машины
