Blockchain pertains to a method wherein information is recorded. This makes it difficult or impossible for the system to be manipulated, changed or hacked. A blockchain refers to a distributed ledger. It duplicates and distributes transactions throughout the network of computers existing in the block-chain. It's a structure that accumulates transactional records of the public in various databases. This storage is generally called a digital ledger.
Every transaction happening in this ledger gets authorized by the owner's digital signature. This authenticates the transaction as well as safeguards it from any tampering. The information contained in the digital ledger is highly secure. It's like a Google spreadsheet that's shared among multiple computers in a network. The transactional records here are stored according to actual purchases. Anybody can see the data but cannot corrupt it.
After this blockchain overview, let's move on to what this blockchain tutorial covers. The term 'blockchain technology' has become quite famous in the past few years probably around cryptocurrencies like Bitcoin. Every enthusiast aims at understanding this tech better.
Blockchain is growing and becoming more user-friendly by the hour. Learning this technology can help prepare for the future. This article covers many questions like why blockchain and how to become a blockchain developer. Let's get started.

The question of the hour is why does one need block-chain. There are many reasons behind the rise of this tech and its continued growth. Here are top reasons why block-chain is a good pick.
Data is crucial and sensitive, and block-chain significantly alters how this critical information is viewed. Block-chain creates an unalterable and end-to-end encrypted record to help prevent unauthorized activity and fraud. Personal data can be anonymized to address privacy issues on the block-chain. Permissions are used to prevent access.
Every organization will have to keep a distinct database without blockchain. It employs a distributed ledger to record data and transactions identically in various locations. All permissioned access network participants view the same information simultaneously for full transparency. Every transaction is immutably recorded with time and date stamps. Members can view the complete transaction history and virtually eliminate any fraud opportunity.
This technology creates an audit trail to document an asset's provenance throughout its journey. This helps provide proof where consumers are concerned about human or environmental rights issues regarding a product. Sharing data about provenance is also possible directly with customers. Weaknesses in any supply chain also gets exposed with traceability data.
Traditional paper-oriented processes are prone to human mistakes, require third-party mediation and are time-consuming. Transactions can be completed faster and more efficiently by streamlining such processes with block-chain. Documentation can be stored on the block-chain with transaction details without the need to exchange paper. Clearing and settlement are much faster since reconciling multiple ledgers is not needed.
Smart contracts automate transactions to increase efficiency and rev up the process. Next step in the process or transaction automatically gets triggered once the pre-set conditions are fulfilled. These lessen human intervention as well as reliance on third parties for verifying the fulfillment of contract terms.
How to become a blockchain developer is one question that's asked quite often. There are many things one must do to become a developer in this tech. The obvious beginning being understanding its fundamentals. This blockchain tutorial covers the often-traced steps to success in this field.
