Blockchain Glossary: Blockchain Terms and Terminology

In an age dominated by the digital revolution, few terms have garnered as much intrigue and attention as “blockchain.” Blockchain promises to decentralize everything from data to security to payments. 

Yet, for many, the labyrinth of terminologies surrounding this innovation can be daunting. This is where a “blockchain glossary” comes into play.

This glossary simplifies complex jargon so that novices and experts alike can understand and participate in the blockchain conversation.

51% Attack 

Suppose a group of miners collectively control over half of the mining hash rate on a given network. This dominance poses a threat to the security and integrity of that network. Such a dominance-driven scenario, particularly associated with Bitcoin, is known as the 51% Attack.

A – All About A’s 

A is for Address

Think of this as the postal address for your cryptocurrency. An address is either an alphanumeric sequence or a scannable QR code, vital for transmitting and receiving transactions. Born from a private key, it’s your unique identifier in the vast world of crypto.

Airdrops Explained

Ever wished for free tokens? Well, in the blockchain world, that’s what airdrops are! Blockchain projects, often Initial Coin Offerings (ICOs), distribute tokens—sometimes with incentives and sometimes without. It’s a strategy to foster community growth, rectify glitches, or promote positive engagement.

The Accidental Fork

Mining can be competitive. Sometimes, multiple miners hit the jackpot and select a block at the same time. As one chain grows longer, the network discards shorter ones, labeling them as “orphaned blocks.”

Agreement Ledger

Picture a shared ledger used by various parties to hash out an agreement. That’s the essence of an Agreement Ledger.

Altcoins – Beyond Bitcoin

Any cryptocurrency introduced post-Bitcoin falls under the umbrella of “Altcoins.” While Bitcoin was revolutionary, Altcoins like Litecoin, LEND, NEO, and EOS bring their own set of features to the table.

ASIC – A Powerhouse Chip

Engineered for a specific task, the Application Specific Integrated Circuit (ASIC) offers enhanced efficiency compared to traditional hardware like CPUs and GPUs. It’s the ace up the sleeve for Bitcoin miners.

API – Building Bridge

The Application Programming Interface (API) acts as a bridge, facilitating seamless interaction between distinct software applications.

Attestation Ledger

Need proof of a transaction? Turn to the Attestation Ledger. It’s a record-keeping tool, confirming transactions and commitments.

B – Blockchain Basics

Blockchain Techonology

Imagine a chain of records, each cemented in place and shielded from alterations. Blockchain operates as a transparent, accessible ledger, immortalizing everything from identities to agreements. Bitcoin and Ethereum are just a couple of its myriad applications.

Bitcoin – The Trailblazer

The OG of cryptocurrencies, Bitcoin is a decentralized currency operating on a peer-to-peer network. While it’s a technological marvel, it also serves as an incentive for miners.

Decoding Bitcoin

• Bitcoin with an uppercase ‘B’? You’re talking about the network.
• bitcoin with a lowercase ‘b’? That’s the cryptocurrency token.

Bounties

In the tech world, businesses often encourage positive contributions through bounties. From fixing bugs to crafting content, bounties reward proactive inputs.

All About Block

Blocks are the building blocks of blockchain, recording digital transactions. Once engraved in the chain, they’re unchangeable.

Earning with Block Rewards

For miners, cracking a block can be lucrative. Successful decryption fetches them a block reward. Depending on their contribution, miners might also share this bounty.

Height Matters – Block Height

The chain’s length, measured in blocks, is termed as its Block Height. The inaugural block? That’s the Genesis Block at height 0.

Understanding Block Ciphers

Encryption can be intricate. Block ciphers operate by encrypting chunks of text using a specific algorithm and cryptographic key, rather than bit by bit.

C – Crypto’s Core C’s

Navigating Central Ledgers

Think of a central ledger as a book that’s held by a main body or organization. It’s where they note down all essential details.

The Magic of Chain Linking

Imagine two different chains being able to talk to each other. Chain linking lets different blockchain systems, like Bitcoin, interact and swap assets with other blockchains.

What’s a Confirmation?

When a transaction happens on the blockchain, the network checks and verifies it. This check is termed a “confirmation.” The more checks a transaction undergoes, the harder it becomes for any foul play, like double-spending.

Achieving Consensus

When everyone in a network nods in agreement that a transaction is genuine, that’s consensus. It’s like everyone giving a thumbs-up, ensuring all records match.

Diving into Cryptocurrency

Digital money crafted using complex mathematics. Think of them as virtual coins or assets, with popular names being Bitcoin, Ethereum, and Litecoin. There are numerous ways to get them, from buying to mining or even being gifted.

Consortium Blockchain Explained

Here’s a special kind of blockchain. Only a select group gets to validate transactions. Imagine a clubhouse where only certain members can vote. The records might be open to all or just a few. This model is sometimes called “partially decentralized.”

Cryptoanalysis & Cryptojacking

Cryptoanalysis is all about decoding secret messages without a key. On the other hand, crypto jacking is like someone secretly using your computer to mine virtual coins.

Chilling with Cold Storage

Want a super safe place for your digital coins? Cold storage is like a digital vault. Whether it’s a scannable code, a USB, or a special device, it’s designed for maximum security.

D – Digital Ledger Details

D for dApp and More

dApp is short for “decentralized application”. Imagine a game or app that runs on various computers and isn’t controlled by a single entity. Then there’s “A DAO”, think of it as a company that runs on its own without humans, based on set rules. “The DAO”, on the other hand, is a unique fund model on the Ethereum platform.

Decryption & Distributed Ledgers

Decryption turns coded messages into readable text. Distributed ledgers, meanwhile, are like databases scattered everywhere—from one city to a whole country.

Signatures & Spending in the Digital World

A digital signature is a unique code ensuring a document is genuine and comes from a legit source. Double spending? That’s someone trying to use the same digital coin twice.

Digital Assets & Identities 

A digital commodity is something valuable you can’t touch but can transfer electronically. Meanwhile, a digital identity is the online face of a person, device, or company.

DYOR & Difficulty

DYOR stands for “Do Your Own Research”, a crucial mantra for investors in the unpredictable world of cryptocurrency. Difficulty? It’s how tough it is to validate and verify blocks in the world of blockchain mining.

E – Essential E’s

Making Sense of Encryption

Imagine you’re sending a secret message. Encryption scrambles that message, turning it into a jumble of characters only specific people can understand.

Unpacking Ether (ETH)
