What is Blockchain

A decentralized ledger of all transactions across a network, enabling secure, transparent, and tamper-proof data storage and transfers without the need for intermediaries.

Blockchain is a state-of-the-art solution saving the growing list of records of any online activity or action as pieces of blocks using cryptography.

A chain of blocks containing data that is bundled together. This database is shared across a network of computers (so-called distributed ledger network). Each data block links to the previous block in the blockchain through a cryptographic hash of the previous block, a timestamp, and transaction data. The blockchain only allows data to be written, and once that data has been accepted by the network, it cannot be changed.

It is a distributed and immutable ledger that provides tracking of assets or information in a network.

Tamper evident and tamper resistant digital ledgers implemented in a distributed manner, usually without a central authority.

An encrypted ledger that protects transaction data from modification.

Blockchain is a decentralized, immutable, secure data repository or digital ledger where the data is chronologically recorded. The initial block named as Genesis. It is a chain of immutable data blocks what has anonymous individuals as nodes who can transact securely using cryptology. Blockchain technology is subset of distributed ledger technology.

A blockchain is a distributed database that is shared among the nodes of a computer network. As a database, a blockchain stores information electronically in digital format. Blockchains are best known for their crucial role in cryptocurrency systems, such as bitcoin, for maintaining a secure and decentralized record of transactions. The innovation with a blockchain is that it guarantees the fidelity and security of a record of data and generates trust without the need for a trusted third party. One key difference between a typical database and a blockchain is how the data is structured. A blockchain collects information together in groups, known as blocks, that hold sets of information. Blocks have certain storage capacities and, when filled, are closed and linked to the previously filled block, forming a chain of data known as the blockchain. All new information that follows that freshly added block is compiled into a newly formed block that will then also be added to the chain once filled. A database usually structures its data into tables, whereas a blockchain, like its name implies, structures its data into chunks (blocks) that are strung together. This data structure inherently makes an irreversible timeline of data when implemented in a decentralized nature. When a block is filled, it is set in stone and becomes a part of this timeline. Each block in the chain is given an exact time stamp when it is added to the chain.

A blockchain is a decentralized, distributed, and public digital ledger that is used to record transactions across many computers so that any involved record cannot be altered retroactively, without the alteration of all subsequent blocks. This allows the participants to verify and audit transactions independently and relatively inexpensively.

Blockchain refers to a decentralized history of transactions shared between various participant. The blocks of a blockchain are connected chronologically where each block is linked to the previous block. Changing an arbitrary transaction requires altering every block, while the rest of the network is following the longest chain.

It is based on Distributed Ledger Technology(DLT), which works on the principle of game theory, cryptography, and P2P technology.

An expanding list of cryptographically signed, irrevocable, time-stamped transactional records shared by all participants in a network, containing reference links to previous transactions useful for tracing transactions.

List of blocks distributed and linked via cryptography such as a digital ledger.

The term for a system of recording information in a way that makes it difficult or even impossible to change back or cheat the system. A block chain is essentially a digital ledger of transactions that is duplicated and distributed across the network of computer systems on the block chain. Because all parties involved in the production and distribution of the goods or services see every transaction simultaneously, not only is system integrity enhanced, so is speed of movement, facilitating planning based on estimates of costs of inputs and profit targets, etc.

A blockchain is a continuously expandable list of data records, which are linked together by cryptographic methods.

Blockchain, in computer terminology, refers to an ever-growing register of transactions held by blocks linked in a chain. The warehouse where these blocks, which are peer-to-peer, stores the transaction records, is called the digital ledger.

Is a technology that combines several mathematical, cryptographic, and economic principles that support the existence of a ledger distributed among several participants.

This is a distributed network infrastructure based on protocols, which archives and manages information in a network of devices. The blockchain establishes logical guidelines for the arrangement of blocks in an electronic protocol for distributed processing. Linked together, successive authorized transaction blocks form a chain of exchanges, known as a blockchain.

A system in which a record of transactions made in a cryptocurrency are maintained across several computers that are linked in a peer-to-peer network. The ledger is immutable, which means that the data entered is irreversible. This means that transactions are permanently recorded and viewable to anyone.

Refers to an advanced database mechanism that allows secure and transparent information sharing within a network.

It is a recording system made up of blocks which are connected using cryptography, making the system a lot more secure.

Can be defined as a shared ledger system or an established record of data not owned by a single entity and is used to record data transactions across multiple computers. Other than bitcoin which propagated the idea of Blockchain, the factors as to why the technology has gained popularity are that any digital asset or transaction can be inserted as a block of data (e.g. block) which are securely bound to each other using cryptography (e.g. chain), the industry does not matter. The block is made up of data, hash (A cryptographic fixed output through a mathematical algorithm from an input of any length) and previous hash. Every other member of the network is responsible for verifying the data being added to the Blockchain is real. This is done using a system of three keys (private, public, and the receiver's key) that allow members to check the veracity of the data while also confirming whom it comes from.

A blockchain is like a digital ledger or record book. It's made up of a chain of blocks, where each block contains a list of transactions.

In simple, a blockchain is just a data structure that can be shared by different users using computing data communication network (e.g., peer-to-peer or P2P). Blockchain is a distributed data structure comprising a chain of blocks. It can act as a global ledger that maintains records of all transactions on a blockchain network. The transactions are time stamped and bundled into blocks where each block is identified by its cryptographic hash .

Blocks of data where each block is chained to the next through the use of hashes.

As a technology is a process of continuous recording of transactions keeping them unchanged; as a database it is a decentralized storage of cryptographic information consisting of blocks.

Blockchain is a peer-to-peer distributed ledger technology for a new generation of transactional applications that establishes trust, accountability and transparency while streamlining business processes. Think of it as an operating system for interactions. It has the potential to vastly reduce the cost and complexity of getting things done. The key to Blockchain is assuring data integrity and data lineage (Why Create The Project, 1 st paragraph).

A blockchain platform allows users and developers to create novel uses of an existing blockchain infrastructure.

A ledger filled with a time-stamped series of immutable data records managed by a cluster of servers not normally owned by any single entity. Each of these blocks of data is secured and bound to each other using cryptography. The primary distinction between the public and private blockchains is that private blockchains control who can participate in the network, execute the consensus protocol that decides the mining rights and rewards, and maintain the shared ledger.
