Multi-signature wallet: A cryptocurrency wallet that requires multiple private keys to authorise a transaction, increasing security. Businesses use multi-signature wallets to ensure no single person can move funds without group approval.
Bitcoin halving: An event that reduces the reward for mining bitcoin by half, occurring approximately every four years. This mechanism is built into bitcoin’s code to control its supply and make it a scarce asset, similar to gold.
Hash rate: The total computational power used to process and secure transactions on a blockchain network. A higher hash rate makes a blockchain more secure, reducing the risk of attacks. Investors monitor it to gauge network health.
Bitcoin blockchain: A decentralised digital ledger that records all bitcoin transactions securely and transparently.
Off-chain: Anything done outside of the main blockchain network by a secondary layer or chain.
Lightning Network: A second-layer solution for bitcoin that enables faster and cheaper transactions by processing them off-chain, making it practical for everyday purchases.
Exchange Traded Funds (ETFs): Investment funds that trade on stock exchanges, allowing investors to buy shares representing assets like stocks, bonds, or cryptocurrencies. Investors use bitcoin ETFs to gain exposure to bitcoin’s price movements without directly buying or holding bitcoin.
