BlockchainTechnology_Introduction-merged

Blockchain is a collection of records linked to each other, strongly resistant to alterations, protected using __________ with a foundation of distributed processing.

cryptography

A __________ is a collection of data and a unique alphanumeric value generated using the data called Hash.

Block

The __________ Hash is a code generated based on the data in the Block and is always unique, even though the data could still be the same.

Hash

Each Block contains a Hash of the __________ Block to make it a chain of Blocks.

previous

The first Block in the Blockchain is called a __________ block and won’t have a Previous Hash populated.

Genesis

Consensus model prevents malicious alterations in a Block by requiring nodes to reach a __________ before adding a new Block to the chain.

consensus

In Blockchains, __________ are used to motivate people to run them, often in the form of cryptocurrency.

incentives

Public Key Cryptography (PKC) uses pairs of keys—public keys, essential for identification, and __________ keys used for authentication.

private

Once a Block is written, it’s __________, meaning it cannot be altered.

immutable

Blockchain takes decentralization to an all-new level, ensuring that no single person or body owns any of the __________.

networks

Distributed ledger technology (DLT) removes the need for a __________ to verify transactions, allowing for real-time visibility and accuracy.

central authority

Smart contracts are self-executing contracts with the terms of the agreement between buyer and seller directly written into __________.

lines of code

Public blockchain is a completely decentralized public ledger where __________ can participate.

everyone

Private blockchains can process transactions faster due to a __________ number of nodes involved.

limited

Proof of __________ is a consensus algorithm used to secure the network and prevent double-spending.

Work

The __________ of a transaction ensures that it cannot be altered once added to the blockchain.

immutability

In a __________ blockchain, a group of organizations rather than a single entity governs the network.

consortium

The __________ algorithm used in Ethereum is known for being more energy-efficient than Proof of Work.

Proof of Stake

__________ proofs allow one party to prove to another party that a statement is true without revealing any information apart from its truth.

Zero-knowledge

The practical requirement that most users must lock some of their cryptocurrency to participate in validating transactions is known as __________.

staking

The Ethereum network is primarily used for building and deploying __________ applications that run on blockchain technology.
