# what is blockchain

in one Blockchain (English: blockchain or block chain) is a series of transaction records (also known as blocks) that are connected and protected by cryptography.  Each block contains the encrypted hash of the previous block, the corresponding time stamp and transaction data (usually represented by the hash value calculated by the Merkle tree algorithm), which makes the content of the block difficult to tamper with. The distributed ledger connected by the blockchain allows two parties to effectively record the transaction, and the transaction can be permanently verified.

The relationship between bitcoin and blockchain?

Bitcoin is only possible with blockchain technology. Blockchain is a cryptography technology, and p2p technology and other technologies work together to reach a consensus mechanism to form a distributed ledger, so that every participant has an equal opportunity to keep accounts and prevent chains. Online tampering, so that the economy is not united, through this trust mechanism to create a trusted chain running on the computer, using consensus to prevent attacks. While running on the blockchain, cryptography technology creates a value product, which is Bitcoin. The so-called mining is only used to prove who has more accounts. Any node has the right to collect the latest transaction records and put them in a block. block, and then submit this block for voting review.

What technologies are included in the mysterious blockchain technology?

1. Data blocks for storing data and technologies such as digital signatures and time stamps on them 2. Consensus algorithms for supporting p2p networks and maintenance systems 3. Mining and proof-of-work mechanisms 4. Anonymous transaction mechanisms and Bitcoin Wallet 5. UTXO 6. Merkle tree 7. Double payment 8. Hash function 9. Encryption algorithm 10. Digital signature
