- Blockchain is a decentralized ledger used to securely exchange digital currency
- Distributed database that maintains continuously growing tamper-proof data structure
- The Blockchain metadata is stored in Google’s LevelDB by Bitcoin Core client
- The individual blocks are identified by a hash which is generated using secure hash algorithm (SHA-256)
- Decentralized and no central authority has full control
- Transaction is broadcasted over Bitcoin network to inform everyone that new owner of these coins
- Buy Bitcoins
- Trade based on bitcoins
- Avoid visibility to institutions
- Set your own values for bitcoins
- Finally based on current rates reverse back or buy something property / material
- Avoid any tracking / Value of transaction
- Distributed databases
- Broadcasted to all nodes
- Decentralized
- Everyone has common access across ledgers which are consistemt
- Once we get into the system / datanases
- Keys to decrypt
- Every transaction may have its own hashkeys / token
- Hard to crack without getting complete details as token may play a key role to deter breaking into ledgers
- peer-to-peer version of electronic cash without going through financial institution.
- DCS (Decentralization, Consistency, Scalability) theorem for the blockchain systems
- Consistency - Any read in the distributed system gives the latest write on the nodes.
- Availability - A Client always receives a response at any point of time irrespective of whether the read is the latest write.
- Partition Tolerance - In case of partition between nodes in the distributed system, the system should still be functioning.
- Decentralization - There is no trusted entity controlling the network, hence no single point of failure
- Consistency - The blockchain nodes will read the same data at the same time.
- Scalability - The performance of blockchain should increase with the increase in the number of peers
