What is the blockchain?
As with most technologies, cryptocurrencies like Bitcoin still rely on a database that can track large volumes of transactions and secure them. The solution used by many of the largest digital currencies in the world is the blockchain.
First implemented in 2009, the technology consists of "blocks" that contain batches of time-stamped transactions, each block is linked to the previous one by cryptography, forming a chain.
As the world becomes increasingly smart and interconnected, cryptocurrencies have become an increasingly attractive proposition for growing markets that may not have traditional banking infrastructure. Several Third World developing countries have introduced blockchain-based national currencies. This technology is also used by several major charitable projects to help people without a bank account.
However, blockchain also offers the possibility of creating an anti-fraud system for exchanges. This gives it enormous potential for use outside of the realm of digital currency, which not only appeals to traditional financial institutions, but also to areas as diverse as manufacturing, food production, and much more. 39; others.

How does Blockchain work?
A blockchain system consists of two types of records, transactions and blocks. Transactions are simply the actions performed at a given time, they are stored together in a block.
What makes the Blockchain more unique is that each block contains the cryptographic hash of the previous one, thus forming a chain. A cryptographic hash takes the data from the previous block and transforms it into a compact string. Since these strings are impossible to predict, this means that any alteration in the string is easily detected.
This method means that the blocks do not need serial numbers, the hash allows them to be uniquely identified and verify their integrity. Each block confirms the validity of the preceding one up to the "genesis block" at the beginning of the chain.
However, linking blocks is not the only thing that secures the chain. It is also decentralized. Each computer the software is installed on has a copy of the blockchain that is constantly updated with new blocks. There is no centralized server that holds the transactions, and since each new block has to meet the chain's requirements, no one can overwrite the previous transactions.
Other transaction requirements can be added to define what constitutes valid input. In Bitcoin, for example, a valid transaction must be digitally signed, it must spend one or more unspent outputs from previous transactions, and the sum of the transaction results cannot exceed the sum of the inputs.
What are some of the largest blockchain databases?
Blockchain's popularity has exploded in recent years, gaining financial backing in the areas of technology and finance.
Far from Bitcoin, which is still the best known and probably the most widely used network, this has led to a number of alternative blockchains that have appeared lately.
This includes R3, which is developing a blockchain technology that can be used by major banking institutions. In May 2017, it raised € 107 million in funding from donors such as Intel, HSBC, and Bank of America.
Hyperledger is another major player, an open source cross-industry collaboration created by the Linux Foundation to popularize blockbuster-based books.
The so-called "big four accounting firms" also said they were testing blockchain technologies, although to date only Ernst and Young have gone public with their technology, making a digital wallet available. of all its Swiss employees.
In March 2017, IBM announced the creation of its own Hyperledger-based "blockchain-as-a-service" offering, which will allow clients to create secure networks.
Earlier this year, the London Stock Exchange also revealed that it was about to start using blockchain to improve transparency of stock information among unlisted companies, hence showing the impact of the technology.
What is the security level of blockchain?
Thanks to its advanced cryptographic protection systems, blockchain theoretically offers a much more secure experience than traditional banking.
The fact that the technology is decentralized and cannot be modified or modified retroactively is ideal for financial transactions and storage of important information.
Blockchain also takes the opportunity to preserve user privacy, which has unfortunately made it increasingly popular as a preferred method of payment for cybercriminals, since a Bitcoin network node is not to reveal the identity of the person receiving. the payments.
