Most bitcoin wallets as well as the blockchain itself are zero knowledge software. XPub is short for xPublic Key and the key used to generate all of your bitcoin addresses. A Bitcoin Transaction is https://www.tokenexus.com/ recorded on the blockchain when any user sends bitcoin from one address to another. A transaction can be sent from as little as a single address and sent to a single address or multiple addresses.
Fork Choice Rule
A permissioned ledger is much easier to maintain and considerably faster than a public blockchain. For example, Quorum or Hyperledger Besu are permissioned ledgers that can be more easily set up for large enterprises. In contrast, the public Ethereum blockchain is a permissionless ledger which anyone can access. JSON-RPC is, quite simply, a method used to move data around computer systems, and predates public blockchain technology. Even though this prefix is originally Greek, our current usage comes from cryptography. Technologies that are referred to with the blanket term of “crypto” tech are underlain by cryptographic tools and processes (such as public/private key pairs) that enable innovative functionality and security.

Every once in a while, an old block hash is hardcoded into Bitcoin software. Checkpoints prevent various DOS attacks from nodes flooding unusable chains and attacks involving isolating nodes and giving them fake chains. Satoshi announced the feature here and it was discussed to death here. When you have the private key you are responsible for and have complete control over the crypto contained in your wallet.
A Glossary of all the Cryptocurrency Terms you need to know
There were 50 bitcoin mined in the Genesis block and they are still in at the same address to this day. An Exit Scam is when a company runs away with other people’s bitcoin or cryptocurrency. Dusting Attacks are an attack on bitcoin Bitcoin Vocabulary privacy by sending tiny amounts of bitcoin to addresses that have been used in the past in an attempt to link owners of old addresses to new addresses. A Distributed Ledger is one of the primary characteristics of a blockchain.
DDoS attacks are a common way for hacker groups to attack a website in an attempt to overwhelm the server with bot traffic. The Dark Web is a part of the internet that requires special tools to access and usually deals in black market goods and services. Although the dark web has a reputation for illicit activity, not everything sold on the dark web is illegal. The purpose of decentralized/distributed apps is to provide a solution to a problem without a central server or point of failure. Cloud Mining services offer the ability to rent miners in remote locations around the world.
It can be a struggle to find definitions for crypto terminology, especially if you’re in the early stages of exploration. Here’s a blockchain lingo guide to help you navigate the exciting frontier of Web3. ExchangeTraditional exchanges facilitate the sale and purchase of assets such as stocks, bonds and currencies.Cryptocurrency exchanges allow parties to buy and sell digital money. Bitcoin protocolThe software, or ‘rules’, that governs the Bitcoin network.All computers forming the Bitcoin network run the same software via the internet, connecting them in a decentralised network. So, with the hope of helping to ‘decrypt’ the cryptocurrency world and its language, here we explain some common concepts, terminology and jargon. Memory pool, files with data about valid transactions that are not included into the block as they are unconfirmed.
Blockchain Transmission Protocol (BTP)
A strategy for selecting which outputs to spend that avoids merging outputs with different histories that could leak private information. An identifier used to uniquely identify a particular transaction; specifically, the sha256d hash of the transaction. Signature hash type that signs the output corresponding to this input (the one with the same index value), this input, and any other inputs partially. Allows modification of other outputs and the sequence number of other inputs.
- Used in Bitcoin to authorize spending satoshis previously sent to a public key.
- Each piece of software connected to the main Bitcoin network is called a node.
- For example, the genesis block has a height of zero because zero block preceded it.
- Bitcoin Improvement Proposals (BIPs) are formal documents that propose changes, enhancements, or additions to the Bitcoin protocol or related processes.
ERC-20 is a technical standard for smart contracts which is used to issue the majority of tokens (in particular, cryptocurrency tokens) extant on Ethereum. This list of rules states the requirements that a token must fulfill to be compliant and function within the Ethereum network. DecentralisedMost cryptocurrencies are by very nature, decentralised. A private key is a combination of letters and numbers that is used in cryptography, similar to a password.
- Navigating crypto taxes can be a challenge as crypto investors often deal with multiple wallets, transactions across various exchanges, and complex on-chain activities such as staking, airdrops, DeFi and NFT trading.
- For Bitcoin or Ethereum, the total market cap is a reflection of the current existing supply times the market price.
- Each block is ‘chained’ to the next block using a cryptographic signature.
- Centralized exchanges, operated by companies like Coinbase and Gemini, function as intermediaries, while decentralized exchanges do not have a central authority.
- Transaction time in Bitcoin refers to the amount of time until a transaction is confirmed.
Medium of Exchange
A small fee imposed on transactions sent across a blockchain network. These fees are used to pay network validators or miners for their participation in consensus, and thus ensure that a blockchain network is self-sustaining. A full node is a computer that can fully validate transactions and download the entire data of a specific blockchain. In contrast, a “lightweight” or “light” node does not download all pieces of a blockchain’s data, and uses a different validation process. An internal transaction on the Ethereum network is one that occurs between smart contracts, rather than between addresses.
