Block size is crucial for the scalability and speed of transactions on the blockchain. A Block Explorer is a tool that allows users to view information within a blockchain. This means they are purchased directly Bitcoin Vocabulary from miners who mined the bitcoin directly. Groups of cooperating miners that agree to share Bitcoin block rewards.

• Bit is a common unit used to designate a sub-unit of a bitcoin – 1,000,000 bits is equal to 1 bitcoin (BTC or B⃦).

The root node of a merkle tree, a descendant of all the hashed pairs in the tree. Block headers must include a valid merkle root descended from all transactions in that block. A variation on HD wallet extended keys where only the hardened extended private key can derive child keys.

Internal Transaction

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.

Client-Side is when information is stored in the user’s hardware or device. Private keys on most desktop wallets keep the user’s private keys on the client while private keys stored under the custody of a third party are server side.

• Stablecoins are cryptocurrencies that are backed by government currencies, like the US dollar or euro.
• Both bitcoin and Nostr operate on decentralized, peer-to-peer networks.
• Blocks whose parent block has not been processed by the local node, so they can’t be fully validated yet.
• Initial Block Download (IBD) is the process by which a new node downloads and verifies the entirety of the blockchain history.
• Lambo is most commonly used in relation to when the price of 1 bitcoin will be able to buy a Lamborghini.
