This database server should be a dedicated machine, that is provisioned to only act as a database server for POS Terminals. This is the usual setup that you see at large supermarkets or department stores. All POS terminals are configured to access the same database server. Some establishment use a redundant server for fail-over purposes.

Hyperledger Context We are witnessing the transition from centralized computing, storage, and processing to decentralized architectures and systems.

Distributed Ledger Technology DLT A distributed ledger is a type of data structure which resides across multiple computer devices, generally spread across locations or regions.

Distributed Ledger Technology includes blockchain technologies and smart contracts. While distributed ledgers existed prior to Bitcoin, the Bitcoin blockchain marks the convergence of a host of technologies, including time-stamping of transactions, Peer-to-Peer P2P networks, cryptography, and shared computational power, along with a new consensus algorithm.

In summary, distributed ledger technology generally consists of three basic components: Blockchain is a peer-peer distributed ledger forged by consensus, combined with a system for smart contracts and other assistive technologies. Consensus refers to a system of ensuring that parties agree to a certain state of the system as the true state.

A block refers to a set of transactions that are bundled together and added to the chain at the same time. In the Bitcoin blockchain, the miner nodes bundle unconfirmed and valid transactions into a block. Each block contains a given number of transactions.

In the Bitcoin network, miners must solve a cryptographic challenge to propose the next block. Transactions The record of an event, cryptographically secured with a digital signature, that is verified, ordered, and bundled together into blocks, form the transactions in the blockchain.

Cryptography has a key role to play both in the security, as well as in the immutability of the transactions recorded on blockchains. Cryptography is the study of the techniques used to allow secure communication between different parties and to ensure the authenticity and immutability of the data being communicated.

For blockchain technologies, cryptography is used to prove that a transaction was created by the right person. It is also used to link transactions into a block in a tamper-proof way, as well as create the links between blocks, to form a blockchain.

Timestamping is another key feature of blockchain technology. Each block is timestamped, with each new block referring to the previous block. Combined with cryptographic hashes, this timestamped chain of blocks provides an immutable record of all transactions in the network, from the very first or genesis block.

A block commonly consists of four pieces of metadata: The reference to the previous block The proof of work, also known as a nonce The timestamp source: It is an anti-tamper mechanism to ensure that the large dataset has not been changed.An inventory turnover of means that the inventory turns over about times a month, or 18 times a year.
