For a public blockchain, the decision to add a transaction to the chain is made by consensus . This means that the majority of “nodes” (or computers in the network) must agree that the transaction is valid. The people who own the computers in the network are incentivised to verify transactions through rewards.
Read moreWhat are transactions in a blockchain?
Blockchain is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system. A blockchain is essentially a digital ledger of transactions that is duplicated and distributed across the entire network of computer systems on the blockchain .
Read moreWhat is Blockchain technology a step by step?
A blockchain is a distributed database, meaning that the storage devices for the database are not all connected to a common processor . It maintains a growing list of ordered records, called blocks. Each block has a timestamp and a link to a previous block.

Ethereum is the best secure block chain based secure crypto currency platform . I helps to develop secure transparent crypto currency solutions for our customers. Hyperledger Fabric is one of the most permissioned blockchains.
Read moreWhat does a blockchain need?
Because of its open nature, these blockchains must be secured with cryptography and a consensus system like proof of work (PoW) . A private or permissioned blockchain, on the other hand, requires each node to be approved before joining.
Read moreWhat are Blockchains technology?
Blockchain technology is most simply defined as a decentralized, distributed ledger that records the provenance of a digital asset . By inherent design, the data on a blockchain is unable to be modified, which makes it a legitimate disruptor for industries like payments, cybersecurity and healthcare.
Read moreHow data is written to a blockchain model?
Blockchains are write-only data structures with no adminis- trative permissions for editing or deleting of the data . The data structures are known as blocks and are distributed in a P2P network. Each block contains the cryptographic hash function of the previous block and is used to develop a link between them.
