Block chain technology is a decentralized data management technology.
Blockchain technology uses composer modeling language. System devoloping front end ( client ) applications using composer API.
It is a distributed ledger technology (DLT) makes the history of any digital asset. This technology records the provenance of a digital asset.
Blockchain technology is the brainchild of Satashi Nakamoto (Pseudonym of Inventer of cryptocurrency) , which enables digital information to be desrupted. A network of computing nodes makes up the blockchain.
Blockchain are often described as * Collection of records.*In which data stored in blocks, each block linked with one another. *Strongly proof against alteration.* Protected using encryption.
Blockchain and other crypto currencies and their wallets are created by computer experts , without taking permission from any government or centre.
Durability, robustness, success rate, transparency, incorruptibility are enticing characteristics of blockchain.
By design Blockchain could be a decentralized technology which is employed by a world network of the pc to manage Bitcoin transactions easily.
Many new business applications will end in the usage of Blockchain like crowd funding, Smart Contracts, Supply chain auditing etc.
Bitcoin and Blockchain concepts have applications in business situations.Building compelling Blockchain applications is finished by using the Ethereum Blockchain.
Moving towards application point of view, one should devolope a strong grasp of core Blockchain platforms, understand what Bitcoin is and the way it works , should learn key vocabulary and ideas commonly used when discussing Blockchain and understand why engineers are motivated and creating technologies using Ethereum.
Designing, testing and deploying secure smart Contracts are done usually by using latest versions of Ethereum development tools. Developing hyper ledger Blockchain applications are done by using composer frame work.
Leverage composer rest server to style web based solutions. Blockchain Designing Hyperledger fabric composer business networks. Here we’ve to grasp actuality, purpose and capabilities of Ethereum and solidity.
By inherent design , the info on a blockchain is unable to be modified , which makes it legitimate disruptor for industries like payments , cybersecurity and healthcare .
The technology is unalterable and transparent through the utilization of decentralization and cryptographic hashing.
Blockchain is more complicated than a Google Doc , but the analogy is apt because it illustrates these critical ideas of technology .
Bocks : Every chain consists of multiple blocks and each block has these basic elements.
1) The data in the block 2) A 32-Bit whole number called a nonce . The nonce is randomly generated when a block is created , which then generates a block header hash. 3) The hash Is a 256-bit number wedded to the nonce . It must start with huge number of zeroes . (ie. Be extremely small )
Miners :Blockchain “mining” is a metaphor for the computational work that nodes in the network undertake in hopes of earning new tokens. In reality, miners are essentially getting paid for their work as auditors. They are doing the work of verifying the legitimacy of Bitcoin transactions.
Crypto is one of the main application field of blockchain.
Cryptocurrencies are a kind of digital or virtual currency.Crypto currencies are proof against counterfeiting, don’t require a central authority.Protected by strong and sophisticated encryption algorithms.Transaction details are permanently inscribed within the blocks.
Blockchain records for crypto also holds the amount of bitcoins each of the account holder holds their own. A hacker won’t be ready to alter the info within the blockchain because * each user features a copy of the ledger.* the info within the blocks are encrypted by complex algorithms. All of this is often made possible with the assistance of blockchain technology.
Every user within the bitcoin network has two keys.
Public Keys : address that everybody within the network knows of.
Private Keys : Unique address that only the user has knowledge of.
Different Cryptocurrencies use different HASHING Algorithms.
BITCOIN : SHA256
ETHEREUM : ETHASH
Blockchain technology has applications in Medical records, E-Notary, Collecting taxes.
As an example Walmart uses the technology of blockchain for supply chain management. In each step from farm to supermarket blocks are used and within which data encrypted. (Farm>>Storage>>Transportation>>Processing>>Distribution Centre>>Supermarket ).
And if any error happened in supply chain, it is easy to determine where the failure occurred and can be corrected easily.
