What data structures are at the core of blockchain technologies?

For starters, let's first learn what is blockchain technology. Logically, a blockchain is a chain of blocks which contain specific information, but in a secure and genuine way that is grouped together in a network. In other words, blockchain is a combination of computers linked to each other instead of a central server, meaning that the whole network is decentralized.

To make it even simpler, the blockchain development company concept can be compared to work done with Google Docs. You may recall the days of tossing over the doc. documents and waiting for other participants to make necessary edits. These days, with the help of Google Docs, it is possible to work on the same document simultaneously.

The blockchain technique allows digital information to be distributed, instead of copied. This distributed ledger provides transparency, trust, and data security.

Blockchain architecture is getting used very broadly within the financial industry. However, these days, this technology is employed not only for cryptocurrencies, but also for record-keeping, digital notary, and smart contracts.

The traditional architecture of the World Wide Web uses a client-server network. In this case, the server keeps all the required information in one place so that it is easy to update, due to the server being a centralized database controlled by a number of administrators with permissions.

If in the case of the distributed network of blockchain architecture, each participant within the network maintains, approves, and updates new entries. The system is controlled not only by separate individuals but by everyone within the blockchain network. Each member ensures that all records and procedures are in order, which results in data validity and security. Thus, parties that do not necessarily trust each other are able to reach a common consensus.

To summarize things, the blockchain is a decentralized, distributed ledger (public or private) of different kinds of transactions arranged into a P2P network. This network consists of many computers but in a way that the data cannot be altered without the consensus of the whole network (each separate computer).

The structure of the best blockchain development company in India uses the technology which is represented by a list of blocks with transactions in a particular order. These lists can be stored as a flat file or in the form of a simple database. Two vital data structures used in blockchain include:

Pointers - variables that keep information about the location of another variable. Specifically, this is pointing to the position of another variable.

Linked lists - a sequence of blocks where each block has specific data and links to the following block with the help of a pointer.

Blockchain architecture can serve subsequent purposes for organizations and enterprises:

Cost reduction - lots of money is spent on sustaining centrally held databases (e.g. banks, governmental institutions) by keeping data current secure from cyber crimes and other corrupt intentions.

History of knowledge - within a blockchain structure, it's possible to see the history of any transaction at any moment in time. This is an ever-growing archive, while a centralized database is more of a snapshot of information at a specific point.

Data validity & security - once entered, the data is hard to tamper with due to the blockchain’s nature. It takes time to proceed with record validation since the process occurs in each independent network rather than via compound processing power. This means that the system sacrifices performance speed, but instead guarantees high data security and validity.
