What is NFT? Non-Fungible Token (NFT) is a kind of blockchains.
What distinguishes NFTs from fungible , and ownership of the NFT is often associated with a license to use the underlying asset.
There are standards or convensions for NFTs on blockchain. For example, ERC-721 is a standard for representing non-fungible digital assets on the Ethereum blockchain, and SimpleAssets is an digital assets standard for NFTs, FTs and NTTs on EOSIO blockchains.
A cryptographic hash function is a hash function that satisfies the properties of pre-image resistance, second pre-image resistance and collision resistance. Here, a hash function is a mathematical algorithm that maps data of an arbitrary size (or “message”) to a bit array of a fixed size (the “hash value”, “hash”, or “message digest”), that is,…
Bitcoin is the world’s first cryptocurrency on the Bitcoin blockchain network. BTC has gained significant popularity since its inception in 2009. It functions as a decentralized, peer-to-peer electronic cash system, allowing users to make transactions without the need for a central authority. Bitcoin History Bitcoin’s story begins with the release of a whitepaper by an…
Proving ownership of a Bitcoin (BTC) address is a crucial aspect in various scenarios, such as verifying identity in a transaction or demonstrating holdings without revealing private keys. This guide explores how to prove ownership for different BTC address types, including algorithm specifications and step-by-step methods. BTC Address Types P2PKH (Pay-to-Public-Key-Hash) P2SH (Pay-to-Script-Hash) P2WPKH (Pay-to-Witness-Public-Key-Hash)…
Multisig, short for “multisignature,” is a cryptographic mechanism that requires multiple signatures to authorize and execute a transaction. What is Multisig Multisig ensures that multiple parties must collaborate and approve a transaction before it can be deemed valid. It provides an additional layer of security requiring multiple parties’ signatures to spend or transfer the crypto…
Cryptographic tokens, or crypto tokens, are tradable digital units of assets that reside on blockchains. These tokens have become increasingly popular in recent years due to the rise of cryptocurrencies and the growing interest in non-fungible tokens (NFTs). Both fungible and non-fungible tokens play a significant role in the world of blockchain technology and digital…
Linear consistency models are crucial in ensuring reliability and coherence in distributed computer systems. These models help manage how systems handle data and operations across multiple nodes, ensuring consistency without sacrificing performance. What is a Linear Consistency Model? In distributed computing, a linear consistency model ensures that operations on distributed data appear as if they…
