Keeping transactional data safe

​The Datacentrix digital experts solve real-world problems using blockchain as a reliable system for recording information and transactions to guarantee information accuracy, integrity, security and consistency throughout the network without fail.
 
As a concept, blockchain is a distributed public ledger where transactions are governed and maintained by protocols through consensus of the nodes participating in its network.

• The data structure comprises blocks that are linked together as a chain
• Transactions are grouped together to form logical containers

 
Blockchain is a peer-to-peer distributed network where all the nodes in the network are deemed equal to each other.
 

• Nodes perform the exact same set of operations and maintain the exact same copy of the ledger across all nodes
• Transactions are maintained through mutual consensus among the participating nodes on the network
• A block of transactions is only added into the distributed ledger when a majority of the nodes approve its validity.
• Once a block of transactions is added to the distributed ledger, it becomes immutable and cannot be changed by anyone within the network.

 
Public blockchains

• Blocks are public as long as participants have network access and can identify themselves to the network.

 
Private blockchains

• Access is administered by a central administrative entity within the network.
