A second-layer solution that reduces the total on-chain transactions necessary by moving the transactions off-chain and letting participants sign to the main chain after multiple off-chain transactions.
The percentage of crypto in a particular account that can be traced to another account.
A blockchain alternative developed by IOTA using acylic graphs which only builds in one single direction and in a way that never repeats.
Technical Analysis/Trend Analysis (TA)
A method of evaluation that makes use of charts and financial instruments to create a statistical analysis of market activity, such as price and volume.
An alternative blockchain used for testing purposes by developers.
Timelock / Locktime
A term used to describe a condition in which a transaction can only be processed at a certain time or block on the blockchain.
A stamp used to identify when a certain transaction has occurred. The stamp typically includes the date and time of day with an accuracy to fractions of a second.
Token Generation Event
Refers to the time in which a token is created and issued.
The process in which a real-world asset is converted into digital value called a token.
An cronym for The Onion Router, TOR is a free software that allows a user to communicate anonymously on the internet.
Refers to the total amount of cryptocurrency in existence in the present time.
A fee deducted for using the blockchain to transact.
Tron is a blockchain project dedicated to building the infrastructure for a decentralized Internet. While the project initially started as a decentralized entertainment platform with distributed storage technology, the project's ambitions have grown to closely resemble those of Ethereum.
TRX is the native token of the Tron blockchain protocol. While the token was initially used only to pay content creators for digital content on the Tron platform, TRX has evolved into a more broadly accepted payment method across Tron's evolving service ecosystem.
A fundamental principle of a blockchain where no participant needs to trust any other participant for transactions to be enforced as intended.
An alternative term for a mixing service.
Refers to the ability of a machine to execute calculations that any other programmable computer is capable of. An example of a Turing-Complete program is the Ethereum Virtual Machine (EVM).
Refers to a state where a transaction has not been confirmed on the blockchain.
Similar to a public blockchain.
Unspent Transaction Output
Unspent Transaction Output (UTXO) is the amount of cryptocurrency that remains after a transaction is executed. Each UTXO represents a chain of ownership, which is represented as a chain of digital signatures in which a transaction originator signs a message transferring ownership of their UTXO to the recipient's public key.
Within the context of blockchain technology, a validator is an entity responsible for verifying and approving transactions submitted by users and/or blockchain clients. Each blockchain protocol has its own parameters for what constitutes an acceptable validator and how these validators operate.
A crypto address where a user can customize their public address with custom letters and/or numbers.
A crypto project that is never actually developed.
A form of private equity provided to fund small, early-stage firms that are deemed to have high growth potential.
A Bitcoin that has never been spent.
Within a marketplace context, volatility refers to the degree of variation an asset's trading prices undergo relative to its mean price over a certain period of time. The more volatile the price of an asset is, the greater the frequency and number of its price changes.
A cryptocurrency wallet is a device or service that stores users' public and private keys, allowing them to interact with various blockchains and to send and receive crypto assets.
Refers to the smallest fraction of an Ether.
A list of interested participants in an ICO.
A white paper is a document produced by blockchain projects which outlines the purpose of the technology they propose to create or have created, and describes how the technology will be implemented, typically in technical terms.
An extended public key. You can think of this as a “view only” wallet. It allows you to see all the transactions, addresses, and balances in a specific wallet. This however does not allow you to spend the bitcoin at all. To be able to send, you need the private key. The XPUB does not hold your private key at all.
This is an extended public key that belongs to wallets following BIP49. This details a backward-compatible addressing scheme for Segregated Witness, or better known as Segwit.
Zero Confirmation Transaction
Alternative phrasing for an unconfirmed transaction.
Zero-Knowledge Proofs are a cryptographic method that provides users with a higher degree of privacy when engaging in digital transactions. In essence, zero-knowledge proofs enable one party to prove to another party that they know a specific value, without conveying any other information apart from the fact that they know that value.
Zero-Knowledge Succinct Non-Interactive Argument of Knowledge (zk-SNARK) is a type of cryptographic proof used to ensure privacy on blockchain-based distributed ledger systems.
