All the Blockchain Glossary Briefing: From A – Z

What is 51% Attack?

When up to half CPU power of a digital currency network generally dominated by any one or more group, sometime it may cause create problems for transaction and harm the network. Also probably the cause the malicious intend to do so.

What is Cryptocurrency Address?

For cryptocurrency transaction you must need an address to send or receive money transaction on the network. Generally, we call it wallet address and address present as a string of alphanumeric characters.

Definition of ASIC

‘Application Specific Integrated Circuit’ briefly ASIC. It is likened to GPUs, ASICs particular use for mining and also assist to saving power significantly.


Bitcoin is a digital cash and peer to peer networking system. It is fully decentralized cryptocurrency and there has no central authority to control. Also, it is the first electronic cash that first ledger started on January 3 2009 by someone apparently name Satoshi Nakamoto.

What is Block?

Blocks are stored on the Blockchain network. Moreover, blocks are packages of data that carry permanently recorded data on the blockchain network. Also blocks consist with a single or more state or data declaration.


Blockchain is an open ledger where every transaction is recorded. This transaction is permanently recorded by appending blocks. The Blockchain indicate all the transaction history that ever occurred, all the block like a genesis block in the recent block and it call the Blockchain. Read the article what is Blockchain?

What is Block Explorer?

It is a helpful online tool to see all the transaction. You can see present, past transaction on the Blockchain network. Additionally, you able to see useful information like network hash rate and the transaction growth.

What is Block Height?

The Block Height refers how many blocks added to the blockchain network. For instant, current Bitcoin block height is 554725.

Block Reward

In a word, Block Reword is an incentive bonus for completing a mathematical problem solve in a block during mining. The miner calculates hash to validate a block in the blockchain network to add new coins. For doing this miner get rewarded a portion of the transaction.

Central Ledger

The central ledger mean, that is maintain by central authority.


The successful act of hashing a transaction and adding it to the blockchain network.

What is Consensus?

Consensus refer all the network member are agreeing to validate a transaction on the blockchain. Additionally, it’s insured everyone are getting copies of the ledger.


Cryptocurrency is a digital currency. For example, Bitcoin is a cryptocurrency. Many of us known as a token or coin those are digital assets.

Cryptographic Hash Function

Cryptographic hashes turn out a fixed-size and distinctive hash price from variable-size dealing input. The SHA-256 procedure rule is computational algorithm example of a cryptographic hash.


(Dapp) decentralized application store the data on the blockchain network. Any central authority is not controlling it. Moreover, it is managed by autonomously. Dapp is fully open source moreover, every can use it and incentives in the form of cryptographic tokens and operates on a protocol that shows proof of value.

Train to Become A Blockchain Developer


It is a decentralize organization that not interfere by any human and all the activities are not control of a single authority. All of the process handling by incorruptible set of business rules.

What is Distributed Ledger?

It is not carry its own currency and perhaps permission and privets. Also, it’s store all the data on the network nodes.

Distributed Network

The distributed network refers to spread all the data among the nodes and not centralize the data.


Actually, difficulty indicate on the blockchain world, how easily calculate and solve mathematics problem. It’s also refers how transaction easily adds a block to mined successfully.

Digital Signature

A web code created by public key encryption that is included to an electronically transmitted document to validate its data and sender identity.

Double Spending

One per transaction cost two time and we called it double spending. Sender and receiver gets fees for one transaction.

What is Ethereum?

Ethereum is an open source blockchain base platform and smart contact featured functionality to protect third party censorship, fraud and control. Founder and author is Vitalik Buterin.

What is EVM?

The Ethereum Virtual Machine (EVM) may be a Alan Turing complete virtual machine that enables anyone to execute discretion EVM computer memory unit Code. Each Ethereum node runs on the EVM to keep up consensus across the blockchain.


Fork refers to another version of the block chain also, to blockchain network work simultaneously on various parts of the network.

Genesis Block

The first origin block or first few blocks of a blockchain.

Blockchain Glossary To Understand Blockchain Tecnology

Hard Fork

Through hard fork all the previous invalidate transaction render to validate and vice versa. To do hard fork there will be need all the nodes and members of that blockchain upgrade to the latest session of the protocol software.


Basically hash function works and performs to output data. It’s need to insure coin transaction. However, It is one of the inportant blockchain glossary.

Hash Rate

Hash rate calculates of operation in the Bitcoin code and the speed of the next block to complete mining process.

Hybrid PoS/PoW

A hybrid PoS/PoW permits for each Proof of Stake and Proof of work as agreement distribution algorithms on the network. Making a system of community-based governance by each insiders (holders) and outsiders (miners).


It’s validating the blockchain transaction. This validating process declares the incentive for the miners. However, miner gets awarded as a validator. Mining is a lucrative business in the cryptocurrency sphere. If you have powerful hardware you can earn a reasonable amount of money.


It is provided an extra security layer by the need of many keys authorize a transaction.


A single copy of the ledger from the blockchain network handling by a participant. Nood is one of the inportant blockchain glossary.


Its performance as a ghat between the real world and the blockchain network by giving data to the smart contracts.

Peer to Peer

Peer to peer (P2P) refers to the decentralize interactions between 2 parties or additional in a very highly-interconnected network. Participants of a P2P network deal directly with one another through one mediation purpose.

Public Address

It is a cryptographic hash of a public key. You can imagine with an email account that can be present for anyone and, unlike private keys.

Private Key

A private key is a string of data that allows you to access the tokens in a specific wallet. However, privet key should secret.

Proof of Stake

A consensus distribution algorithm that rewards earnings based on the number of coins you own or hold. The more you invest in the coin, the more you gain by mining with this protocol.

Proof of Work

A consensus distribution algorithm that requires an active role in mining data blocks, often consuming resources, such as electricity. The more ‘work’ you do or the more computational power you provide, the more coins you are rewarded with.


It is like cryptographic algorithm. Also, it is used by Litecoin. Similar with SHA-256 that is quicker as it do not use up much processing time.


SHA-256 is a particular cryptographic algorithm. Basically used for crypto, for example Bitcoin.SHA-256 need huge computing power. Need process time and enforcement of mining pool to the blockchain network.

Soft Fork

A soft fork is a slit different form the hark forks. It makes an invalid previous transaction. All the past nodes execute in the new block as valid. It is important for a soft fork for backward compatibility. To complete this fork miner need upgrading moreover a hard for need all the nodes to agree with the recent version.


It is a programing language and it’s use on the Ethereum to develop a smart contract.


A test blockchain used by developers to prevent expending assets on the main chain.

Transaction Block

Many transitions are stored in a block after then be hashed and final run on the blockchain.

Transaction Fee

To transact any amount of crypto there has a little charge. Basically to complete this transaction, it adds up the block. Miner get reward for it.

Turing Complete

Turing complete refers to the flexibility of a machine to perform calculations that the other programmable laptop is capable of. AN example of this can be the Ethereum Virtual Machine (EVM).


Simply, wallet refers a store of crypto money. Used file in a place with privet keys. Wallet as act a software client where the user has access to see transaction on the relevant blockchain network.

Finally, Blockchain technology is a new revolution in the internet. Blockchain glossary help you understand blockchain technology. It makes you a good sense about cryptocurrency. So, read every day at lest one blockchain glossary.
