Blockchain has become one of the most talked about technologies in recent years. This decentralization innovation has the potential to transform many industries, from finance to supply chains. One key concept in blockchain is the chain block. But what exactly is a chain block? As Malaysia market, perhaps they ask about apa itu chain block? Let’s explore further.
Chain Block Definition
A chain block is a fundamental component of blockchain. It is a group of transactions recorded in chronological order into a block. Each new block added to the blockchain contains the cryptographic hash of the previous block. This creates a chain linked to each other, hence the term “blockchain”.
Structure For Chain Block
Each chain block has a unique data structure:
- Block Header: This contains metadata about the block itself including the block hash, timestamp, and block number.
- Block Size: The size of the block in bytes. The maximum block size varies across blockchains.
- Block Transactions: These are the actual transactions stored in the block. Can be hundreds or thousands of transactions depending on the blockchain platform.
- Nonce: A value used in cryptographic block mining.
All this information is stored permanently in the chain block. If any detail changes, the block hash will also differ. This helps protect the integrity of blockchain data.
Chain Block Roles
Chain blocks play several important roles in blockchain:
- Recording Transactions: The core function of chain blocks is to record and validate transactions in a decentralized manner. For example, transferring crypto coins between users.
- Providing Transparency: Every node in the blockchain network can view the contents of each chain block and transaction. This creates transparency.
- Adding Security: Linking each block with a cryptographic hash makes blockchains extremely difficult to manipulate or alter.
- Correcting Errors: If an error occurs in one block, other nodes can compare their hashes to validate the correct data and achieve consensus.
- Storing Data: Blockchains can store any data in the form of transactions, including medical records, land titles, smart contracts, and more. Chain blocks enable this.
- Generating Rewards: Some blockchains reward new coins to miners who successfully add a new block. This provides incentives to contribute computing resources.
Creation Process Of Chain Block
How is a new chain block created? Here are the basic steps:
- Miner nodes collect pending transactions waiting to be confirmed into a candidate block.
- They initiate the mining process by trying different nonce values for the block until a valid block hash is found. This requires high computing power.
- The first node to solve this cryptographic puzzle can add their new block to the blockchain.
- Other nodes validate the mining work and accept the block if everything is correct.
- The new block is linked to the previous block and continues building the chain. The process repeats for every subsequent block.
- Thus, chain blocks enable distributed consensus among nodes in a peer-to-peer network. This allows blockchains to continue growing, secure, and decentralized.
