Top Blockchain Development Companies of 2021: At a Glance

Top blockchain development companies do not stop at delivering quality blockchain solutions. They seek growth through collaboration and encouraging other industries to switch to this technology.

Understanding the Blockchain

Blockchain was initially operated as an underlying technology to cryptocurrencies. Built on the principles drawn from cryptography, game theory, and peer-to-peer networking, it is a networking technology, similar to world-wide-web (www), that enables a decentralized exchange of data. Therefore, in a wider sense, blockchain is a distributed database (ledger), which maintains a continuously growing list of timestamped and encrypted transaction records organized in blocks, with each block being linked to a previous block, forming a chain.

Blockchain comes with some native features

Synchronized: All activity on the blockchain is automatically reflected across the network in near real-time.

Traceable: The transaction timestamp is recorded in a block, i.e. all data exchanges can be verified to have taken place at a point in time.

Decentralized: It is a distributed network of databases with potentially no central authority.

Immutable: Validated data is irreversible and cannot be tampered with preventing fraudulent or accidental overwriting. Moreover, it is built-in hashing, linking and consensus algorithm prevents change of historical records.

Secure: All recorded transactions are individually encrypted, but the transactions can be traced back through their cryptographic identities. 

Scalable: A new participant can be rapidly added to the network and a full copy of the ledger will be replicated in their node.

Collaborative: All network participants agree to the validity of each of the records. A new block is only adopted by the network once a majority of its participants agree that it is valid.

Auditable: Provides visibility into transactions through digital signatures, which binds each party to the data exchange in real-time. The digital signatures can be tied back to real-life identities depending upon the implementation. 

Programmable: A concept is known as “smart contracts” allows for instructions to be embedded within nodes, allowing automated rules to be executed for each transaction when predefined conditions are met. 

Permissiononed And Unpermissioned Blockchains

Bitcoin was the first proven implementation of blockchain technology. Therefore, this was followed by the launch of other cryptocurrencies. By now, most people are somewhat aware of how blockchain technology is applied in the context of public network infrastructure, also called “unpermissioned blockchains.” Over the past few years, industry focus has shifted to private and consortium distributed ledgers, commonly referred to as “permissioned blockchains”. Therefore, the “permissioned blockchains” are usually faster. Therefore, this is due to simplified consensus protocols relying on a smaller number of trusted nodes. Thereafter, maintaining and validating ledgers’ integrity.

How Does Blockchain Help Your Business?

Moreover, the need to transfer shares of ownership using the current model would require stacks of paperwork, a legal advisor, or a trusted entity.

Now, in the case of transferring a digital asset such as an art piece. Moreover, it is not possible to prevent people from duplicating the file and sending others a copy. Since there is no way to verify the transfer of assets publicly, there exists no way to enforce the authenticity. Here’s where the blockchain comes into play. Therefore, blockchain is the only technology that allows for the transfer of digital assets in a decentralized and secure way.
