Blockchains are digital ledgers that use cryptography to record transactions and assets – both tangible and intangible – across a network of peer-to-peer computers.
Data storage capabilities extend beyond public-private key pairs and digital signatures; they can also be used for issuing, paying, exchanging, escrow and retirement purposes.

It is a decentralized database
Blockchains are decentralized databases that store data in blocks. Each block includes an immutable timeline that links together into an unchangeable sequence of records.
Distributed databases represent an alternative to traditional, centralized databases that can be vulnerable to hacking or tampering, with each node validated for every transaction occurring within. A distributed database makes manipulation more difficult since all nodes must confirm when one takes place.
This database allows businesses to reduce costs and risks by bypassing intermediaries like banks and credit card companies, for instance instantly disbursing payments to vendors once conditions have been fulfilled.
Blockchain can also be used to track assets such as food shipments, intellectual property rights and patents. Today, various industries are exploring how blockchain technology can streamline business processes and ensure secure transactions.
How to Make Blockchain More Secure
Blockchain is a distributed database, storing transaction information across an interconnected network of computers. This makes it more secure against manipulation, and harder for hackers to break in since if any one copy falls into malicious hands, only that copy will be compromised.
Blockchain’s core principle is immutability – meaning all transactions should be recorded securely so no one can alter them later.
However, blockchains do present various security threats that make the system vulnerable to hacker attack, including routing attacks that intercept data as it travels between nodes in a blockchain network.
These attacks can expose confidential data or extract currency without the user’s knowledge, but there are ways to combat the threats of these attacks; using secure routing protocols and regularly changing passwords are two great examples; also, educating employees about cybersecurity best practices can also help ward off these attacks.
It is tamper-proof
Though blockchain may seem an attractive solution for your data storage needs, there can be risks and security concerns associated with its use. Phishing attacks, code exploits, routing attacks and more all pose potential security threats that may compromise its integrity and jeopardize its safety.
Blockchain technology stores data in blocks connected by unique hashes of each previous block, making it virtually impossible to alter any individual block without also altering every other one in the chain.
Additionally, the consensus algorithm employed by the network ensures that no individual can alter data on the blockchain without receiving approval from all members of its community. This prevents hackers from seizing control of it and making changes to its database.
It is scalable
Blockchain scalability is an integral component of building any blockchain network. Scalability determines how many transactions the network can process per second based on factors like block size and node count in the network.
Current solutions proposed for blockchain scalability issues include sharding, state/payment channels, segregated witness and others.
Scalability issues were once an obstacle to blockchain’s wider adoption; however, these concerns are slowly being addressed by the community as a whole.
Scalable blockchains can increase their throughput and transaction processing time without compromising decentralization or security, providing more opportunities for mass usage.
The blockchain industry has made great efforts to address this challenge, with various solutions emerging that attempt to address it – but all come at the cost of other areas that are essential.
