Blockchain is a distributed ledger technology that combines with IoT to make machine-to-machine transactions possible. It uses a set of transactions that are recorded in a database, verified by multiple sources and entered in a common ledger distributed across every node.
What is block chain in IoT?
IoT enables devices across the Internet to send data to private blockchain networks to create tamper-resistant records of shared transactions. IBM Blockchain enables your business partners to share and access IoT data with you — but without the need for central control and management.
What is an example of an IoT Blockchain system?

IoT and blockchain are working together in unison to make the world a better-connected place. Examples of IoT and blockchain include everything from ledger security on industrial IoT equipment to blockchain being used as a method to track-and-trace IoT-enabled shipping containers.
What is block chain concept?
Blockchain is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system. … Each block in the chain contains a number of transactions, and every time a new transaction occurs on the blockchain, a record of that transaction is added to every participant’s ledger.
What is Blockchain in simple words?
A blockchain is a digital record of transactions. The name comes from its structure, in which individual records, called blocks, are linked together in single list, called a chain. … Each transaction added to a blockchain is validated by multiple computers on the Internet.
What are the advantages and disadvantages of IoT?
Save time: As it reduces the human effort then it definitely saves out time. Time is the primary factor which can save through IoT platform. Enhance Data Collection: Improve security: Now, if we have a system that all these things are interconnected then we can make the system more secure and efficient.
Which one of the following describes a Blockchain?
blockchain, originally block chain, is a growing list of records, called blocks, that are linked using cryptography. … The blockchain has been described as “an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way”.
What are the components of Blockchain?
The four (4) main components of any blockchain ecosystem are as follows:
- a node application.
- a shared ledger.
- a consensus algorithm.
- a virtual machine.
Do you think Blockchain is a good solution to IoT security?
Blockchain, which is most familiar for bitcoin and Ethereum, offers an intriguing solution for IoT security. Blockchain contains strong protections against data tampering, locking access to Internet of Things devices, and allowing compromised devices in an IoT network to be shut down.
Which model describes how data is written to a Blockchain?

What is Blockchain used for?
A blockchain is a decentralized, distributed, and oftentimes public, digital ledger consisting of records called blocks that is used to record transactions across many computers so that any involved block cannot be altered retroactively, without the alteration of all subsequent blocks.
Who invented Blockchain?
Blockchain has the potential to grow to be a bedrock of the worldwide record-keeping systems, but was launched just 10 years ago. It was created by the unknown persons behind the online cash currency bitcoin, under the pseudonym of Satoshi Nakamoto.
Where is Blockchain data stored?
Blockchain is decentralized and hence there is no central place for it to be stored. That’s why it is stored in computers or systems all across the network. These systems or computers are known as nodes. Each of the nodes has one copy of the blockchain or in other words, the transactions that are done on the network.
What is Blockchain in plain English?
Blockchain has been defined as a digital ledger in which transactions are recorded chronologically and publicly. … A blockchain consists of a number of blocks, hence the term.
