- "OP_RETURN": Bitcoin transactions include an option called "OP_RETURN," which can be used to permanently embed short messages or data into the blockchain.
- Bitcoin Forks: Several alternative coins (altcoins) have emerged from Bitcoin as forks. Examples include Bitcoin Cash and Bitcoin Gold.
- Testnet: In addition to the mainnet, where real funds are transferred, Bitcoin has a test network (testnet). This network is often used to test new features and conduct experiments.
- Bug Discovery: In 2010, a critical bug was discovered in the Bitcoin protocol. This bug temporarily made it possible to generate an infinite number of bitcoins.
- Unique Addresses: Bitcoin addresses are designed so that no two addresses are ever generated twice. As a result, the probability that someone else will accidentally generate an address identical to yours is practically zero.
- Unconfirmed Transactions: If transaction fees are too low or the network is congested, Bitcoin transactions may remain unconfirmed.
- Block Size: The size of Bitcoin blocks has long been limited to 1 MB, but attempts are being made to increase or modify this size limit through forks such as Bitcoin Cash.
- Bitcoin’s scripting language: Bitcoin has its own scripting language, which can be used to customize transaction conditions.
- Time Lock: Bitcoin transactions feature a function called a “time lock,” which delays the transfer until a specific point in time.
- Cold Storage: To prioritize security, many users and exchanges store Bitcoin in an offline environment, known as “cold storage.”
