The blockchain trilemma is the challenge of balancing three key properties: decentralization, security, and scalability. Achieving all three simultaneously is difficult, and compromises are often made in one area to improve the others.
Blockchain is a decentralized digital ledger technology that records transactions across multiple computers in a way that makes them tamper-proof and immutable. Each block contains a list of transactions, and these blocks are linked together in a chronological chain using cryptographic hashes. This technology enables trustless and transparent transactions without the need for intermediaries.
A block explorer is an online tool that allows users to view and search blockchain transactions, blocks, addresses, and other data.
A block reward is the incentive given to miners for successfully validating and adding a new block to a blockchain.
A burn address is a cryptocurrency address where tokens are sent to be permanently removed from circulation.
A blockchain fork occurs when a blockchain splits into two separate chains. Forks can be classified as hard forks.
