So, to help our reader know the Blockchain history and understand the Blockchain evolution, here we bring a detailed guide to the history of blockchain technology with its detailed evolution.
How did blockchain emerge? Stuart Haber and W. Scott Stornetta envisioned what many people have come to know as blockchain, in Their first work involved working on a cryptographically secured chain of blocks whereby no one could tamper with timestamps of documents. In , they upgraded their system to incorporate Merkle trees that enhanced efficiency thereby enabling the collection of more documents on a single block.
However, it is in that Blockchain History starts to gain relevance, thanks to the work one person or group by the name Satoshi Nakamoto. Satoshi Nakamoto is accredited as the brains behind blockchain technology. Very little is known about Nakamoto as people believe he could be a person or a group of people that worked on Bitcoin, the first application of the digital ledger technology.
Nakamoto conceptualized the first blockchain in from where the technology has evolved and found its way into many applications beyond cryptocurrencies. Satoshi Nakamoto released the first whitepaper about the technology in In the whitepaper, he provided details of how the technology was well equipped to enhance digital trust given the decentralization aspect that meant nobody would ever be in control of anything.
Ever since Satoshi Nakamoto exited the scene and handed over Bitcoin development to other core developers, the digital ledger technology has evolved resulting in new applications that make up the blockchain History.
A very common question, when was blockchain invented? Also Check: Blockchain Fundamentals Presentation. In simple terms, Blockchain is a peer-to-peer distributed ledger that is secure and used to record transactions across many computers. It can also be envisioned as a peer-to-peer network running on top of the internet. In layman or businesses term, blockchain is a platform where people are allowed to carry out transactions of all sorts without the need for a central or trusted arbitrator.
The created database is shared among network participants in a transparent manner, whereby everyone can access its contents. Management of the database is done autonomously using peer-to-peer networks and a time stamping server.
Each block in a blockchain is arranged in such a way that it references the content of the previous block. The blocks that form a blockchain hold batches of transactions approved by participants in a network. Each block comes with a cryptographic hash of a previous block in the chain. Read our previous article Ultimate Blockchain Guide to know more about blockchain technology. Most people believe that Bitcoin and Blockchain are one and the same thing. However, that is not the case, as one is the underlying technology that powers most applications of which one of them is cryptocurrencies.
Bitcoin came into being in as the first application of Blockchain technology. Satoshi Nakamoto in his whitepaper detailed it as an electronic peer-to-peer system. Nakamoto formed the genesis block, from which other blocks were mined, interconnected resulting in one of the largest chains of blocks carrying different pieces of information and transactions. Blockchain runs on specialised computer software that operates behind the scenes, automatically distributing information to the database as new transactions are made.
Most individual users will not see a blockchain performing and this instantaneous nature means there is little to no window of time for someone to alter a transaction before it is recorded on to the ledger.
A blockchain database consists of blocks and transactions. Each block contains the hash of the block before it, which links the two and forms the chain. When a transaction takes place, its details are encrypted and a unique multiple-character transaction number is generated. Instead of other users in the blockchain being able to see the exact details of the transaction, this number is recorded in the ledger as a placeholder. All the users of the network will be able to see that the transaction has taken place but only the parties involved in the transaction can access and view its details.
All this makes any fraudulent activity easier to spot. An external hacker would have to gain access to every computer that holds a copy of the blockchain database, and at the same time, in order to tamper with it. Blockchain technology has been around for a number of years and its most well-known use so far is Bitcoin , the virtual currency that came to prominence in The uses of blockchain are not limited to financial transactions, though, and enthusiasts are looking into other ways applications for the technology, especially for the types of transactions where there are often disputes or trust issues, such as with land rights.
As an emerging technology, blockchain enthusiasts are hopeful it could be the next big development disruptor. In providing a transparent, instantaneous and indisputable record of transactions, its potential to remove corruption and provide transparency and accountability is one area of intrigue.
But there are still many questions around how to apply the technology. Many Zimbabweans have already turned to Bitcoin as a hedge against their national currency, thereby driving the Bitcoin price up on the local crypto-market. In the short term, such efforts might prove very successful. However, many of these early projects will inevitably fail due to the early stage of the technology which is yet to mature and due to lack of in-house knowledge by a respective government in charge.
In a lot of these cases, such experiments will be unintentional. In other words, governments moving forward with a cryptocurrency project may not realize that they are test subjects in their own experiments. Due to the lack of requisite expertise internally, these governments will turn to external consultancies, some of which are newly formed and with limited resources.
As a result, many governments will end up victimized by hackers, due to inadequate or incompletely implemented practices regarding private-key management and related processes. This situation parallels the early days of the Web, where major companies that were successful in commerce but not familiar with e-commerce made mistakes in initial implementations, resulting in loss of data and funds.
In the long run, however, successful cases will emerge. Next generation blockchain technology will resolve many current limitations, such as scalability, privacy controls, toolset maturity, and interoperability. Price-stable tokens regulated by monetary policies and backed by collateral will start to gain traction as they become more reliable as a means of exchange and as a store of value. Prediction 2: Trillion-Dollar Protocols. By , there will be more trillion-dollar tokens than there will be trillion-dollar companies.
There is a race among the four most valued companies in the world based on stock market valuation as to which one will be the first to reach one trillion dollars in value. This new-ish economy is one based on the decades-long transition to digital business and online connections.
The old traditional, pre-internet economy is analog, brick-and-mortar, based on oil and resource extraction, on manufacturing of raw materials and cultivation of foodstuffs and accoutrements, and on the transportation and sale of these through traditional physical channels. Obviously, the real world will not disappear. It is where we live, breathe, eat, and ambulate. But its economic role has declined in the grand scheme of things.
The new-ish economy is a layer of value on top of the physical substrate. It has not yet fully diffused through all corners of the globe and economic sphere. Its impact will continue to grow, hence the high and growing valuation in stock markets.
It is possible that after the first trillion-dollar company, others will also cross that threshold, and there may be three or five. But the next era is emerging, and that may follow a different pattern than previous waves of economic transformation. What the old economy and the new-ish economy have in common is that they are both predicated on the notion of a company.
In business there is a long-standing notion of the theory of the firm, articulated in by Ronald Coase. The theory of the firm seeks to address questions as: Why do firms exist?
Why do they grow? How are they structured? What are the different functions of a firm? And so on. In our view, looking at a company resembles looking at a single-cell organism, looking at its internal subsystems, and at the semi-permeable membrane that permits the flow of certain substances across that boundary. Other transactions and processes must cross the boundary to do business with other entities , but certain functions naturally gravitate inside the walls of the organization or organism.
Blockchain technology changes the nature of this equation. It dramatically reduces the costs of transactions and information flows. Where there was friction and impedance, these levels are lowered. Doing so erodes the traditional rationale for a firm, especially a trillion-dollar firm.
Large firms exist, in part, because there is a huge schism between processes that occur inside the walls versus those that cross to the outside. Blockchain technologies change the equation and favor frictionless flows of tokens and other digital assets.

Blockchain technologies change the equation and favor frictionless flows of tokens and other digital assets.
We are in the dawn of that era, and there will be more trillion-dollar tokens in 10 years than there will be trillion-dollar firms. Prediction 3: Blockchain Identity for All.
By , a cross-border, blockchain-based, self-sovereign identity standard will emerge for individuals, as well as physical and virtual assets. Identity systems, as we know them today, are highly dysfunctional, operating in silos, and insecure.
Blockchain-based identity systems will solve these problems. Blockchain-based identity decentralizes the data collection, cross-verifies the collected data via a consensus mechanism, and stores this information on a decentralized immutable ledger. It enables reduced risk of security breaches, significantly higher efficiencies, higher reliability, and most importantly self-sovereignty. According to various data sources, 1.
Blockchain-based self-sovereign identity platforms will provide the disenfranchised population with tools to obtain and maintain legal documentation.
The new identity platform will be more secure and reliable since it will be stored on a distributed ledger rather than being in the possession of a central authority. Blockchain-based identity platforms will also enable self-sovereignty, which ultimately means individual privacy. With recent Facebook data-breach scandals dominating the news, blockchain-based identity creates a viable and important solution to many data privacy issues.
Some use cases for the types of data stored on a blockchain-based identity platform include but are not limited to :. While it is unlikely that, by , a clear end-to-end solution will emerge as a clear winner, a high degree of interoperability among identity platforms will enable ease of use and global cross-verification. Furthermore, a blockchain-based asset identity platform will collect, store, and share data for both physical and virtual assets. More than 20 billion IoT devices are projected to exist by By their nature, IoT devices are continuously connected to the internet.
They collect, store, and transport unique sets of data. Blockchain will provide a secure, reliable, and efficient mechanism for these devices to transact among one other. Blockchain will keep an immutable record of all interactions and will enable instantaneous payment settlements e. One example of virtual assets would be crypto kitties, fictional cats existing in a virtual game and living on the Ethereum blockchain.
With the power of blockchain, these virtual objects are turned into tokenized assets which, similarly to physical assets, will have their unique identity. Ultimately, blockchain will enable an automated operating system seamlessly connecting individuals with assets in physical as well as in virtual worlds. Prediction 4: World Trade on a Blockchain. By , most of world trade will be conducted leveraging blockchain technology.
One of the most promising areas where blockchain can provide significant business value is global supply chain. In its current state, world trade is conducted via a chaotic, fragmented set of business relationships among parties that are untrusted. This results in inefficiencies, errors, and fraud. This is a set of real-world business problems that are currently unsolved and cannot be fully solved without using blockchain technology. Some examples of real-world supply chain problems that need to be solved are:.
As is evident, the problems in global supply chains are significant and, in some cases, life-threatening. According to WHO, tens of thousands of people die from counterfeit drugs every year. The solution to these problems is difficult because the business ecosystems are fragmented, siloed, only partially automated, and lacking a trusted central authority with jurisdiction, resources and credibility to track provenance and certify authenticity.
Unlike the example of the banking industry, where there is an existing system SWIFT that works correctly and reliably, in the supply-chain examples, there is no proven, working system. July 18, Play outline.

Transactions are recorded on this block and it is added to the existing chain of blocks. It became easy for developers to create DApps when Ethereum introduced a standard token protocol that supported smart contracts.
Smart contracts allow users to transact and perform tasks without third parties supervision. They are basically self-executing contracts that help reduce disputes and contract breaches. Cryptocurrencies are a decentralized virtual money, as such, no government or bank controls their supply or flow. Primarily, cryptocurrencies are mediums of instant transactions or payments that are not limited by geographical locations.
Since cryptocurrencies are not subjected to any central entity, it is impossible to create them the way fiat currencies are minted. Instead, participants miners of blockchains perform specific tasks in order to create cryptocurrencies. The completion of these tasks creates a specific amount of the coin which is allocated to the miner that successfully completes the task.
This process is what we call bitcoin mining. And each blockchain has specific mechanisms that it utilizes to mine its coin. The distributed nature of the blockchain is one of the major selling points of the technology. Distributed applications DApps operate on a network of computers and coordinate its functionalities by sharing a memory or distributing each activity across its nodes. See all upcoming events.

Unlike the example of the banking industry, where there is an existing system SWIFT that works correctly and reliably, in the supply-chain examples, there is no proven, working system.
There is no order, only chaos. Therefore, disruption is not an option, because disruption implies disintermediating or dismantling an existing system. In effect, one is constructing an ERP system for a business ecosystem, which means it will take longer and be more difficult than building an ERP system for a single company. Also, as mentioned earlier, the technology does not yet have the functional scope, flexibility, performance, efficiency, and maturity.
Once it matures, the problems in supply chains are real enough, and important enough that solutions will eventually be built, and blockchain will play a critical role in these future solutions. Prediction 5: Blockchain4Good. Poverty and income discrepancy are arguably the hardest problems for humanity to tackle. More than 2 billion people are considered to be unbanked and have no access to financial services. Blockchain technology has the potential to shrink the poverty gap.
It can be done by increasing financial inclusiveness, reducing corruption, and enabling decentralized access to value-creating assets. Here are three examples. Financial inclusiveness is the most obvious benefit of cryptocurrencies like Bitcoin. As is already evident today, Bitcoin and blockchain enable the unbanked population to get banked, and therefore, get paid.
One no longer needs to rely on a centralized institution, such as the government or a bank, to give you permission to open a bank account. You can buy and sell Bitcoin on an open market provided access to a crypto exchange with access to a smartphone. A number of merchants around the world already accept cryptocurrencies. By , cryptocurrency will serve as a de facto standard, similar to how the US dollar is widely accepted today.
Second, blockchain technology reduces corruption by creating transparency of official records. Whether you are a farmer in rural Latin America or a house owner in Russia, you will no longer be driven out of your land by a corrupt official tampering with the land registry.
All assets, including land, will be recorded on a transparent, tamper-free distributed ledger open for the public to see. Solving this problem alone will have massive financial implications on the global economy. Uncertainty around asset ownership reduces asset price and tradability potential.
Therefore, by creating a transparent, tamper-proof property and asset tracking system, blockchain technology has the potential to increase global wealth.
