Basic concepts of blockchain

Decentralized ledger technology that effectively records transactions between computer networks, ensuring transparency, consistency and reliability.

A. Sections:

• Blocks are the core components of the blockchain.

• Each block contains a list of transactions, along with a time stamp and a description of the previous block.

• Cryptographic algorithms are used to generate the hash data in the block and create a unique identifier for that block.

• Blocks are linked in a chain, where each block points to the hash of the previous block, forming an immutable record of timelines and transactions

B. Muscles:

• Nodes are individual computers or devices that participate in the blockchain network.

• Each node maintains a copy of the entire blockchain ledger.

• Nodes communicate with each other to verify transactions, propagate new blocks, and keep the blockchain consistent across the network.

• A blockchain network consists of different types of nodes, including standard nodes, which maintain a complete copy of the blockchain, and lightweight nodes, which rely on complete nodes for authentication

C. Outsourcing services:

• Decentralization refers to distributing authority and control across multiple nodes in the blockchain network, rather than concentrating it in one central authority

• In a decentralized blockchain network, no single entity controls the network or can change the rules unilaterally.

• Decentralization increases the security, stability and reliability of the network, as it removes single points of failure and reduces the risk of censorship or tampering.

• It encourages integration and fosters innovation by allowing everyone to participate as a node in the network or contribute to its development.

How does blockchain work?

A. Distributed Ledger

1. Recording Communication:

• In a blockchain network, transactions are recorded in a distributed ledger, which is a decentralized database shared across many nodes.
• When a participant initiates a transaction, it is propagated across the network and divided into blocks with other pending transactions.
• Each block contains the cryptographic hash of the previous block, which is a chain of blocks, hence the name “blockchain”.
• Once a block is created, it is verified by network nodes before being added to the blockchain. This validation process ensures that the connection works and complies with the network rules.

2. Concept strategies:

• Consensus mechanisms are protocols used to achieve consensus among network nodes on the validity of transactions and the order of inclusion in the blockchain

a Proof of work (PoW):

1. In PoW, miners compete to use computational power to solve complex mathematical puzzles.
2. When solving a puzzle, the first shooter reports the solution to the network, which is then verified by other nodes.
3. Once verified, the new block is added to the blockchain, and the miner is rewarded in the form of cryptocurrency.
4. PoW ensures network security by requiring miners to install electronic resources, making attacks costly to carry out.

B. Proof of acknowledgment (PoS):

1. PoS appoints validators to create new blocks based on the amount of cryptocurrency they hold and are willing to “deposit” as collateral.
2. Validators are selected probabilistically, with higher stakes increasing the probability of being selected.
3. Acceptors are encouraged to act honestly, as misconduct can result in the loss of their gambling assets.
4. PoS is more energy efficient than PoW and provides scalability while maintaining network security.

B. Crypto Confidential Information

Hash Functions:

• Hash functions are mathematical algorithms that take an input (or ‘message’) and produce a fixed-size string of bytes.
• The output known as hash value or digest is different from the input data.
• In a blockchain, hash functions are used to generate a unique identifier for each block by hashing the block’s data, including transaction details and the hash of the previous block
• This hash value acts as a digital fingerprint for the block, ensuring data integrity and unalterability.

Digital Signature:

• Digital signatures are cryptographic techniques used to ensure the integrity and authenticity of messages or transactions.
• Each participant in a blockchain network has a public-private key pair.
• To create a digital signature, the sender uses its private key to encrypt the transaction information, generating a unique signature.
• Recipients can use the sender’s public key to verify the signature, and confirm that its message was indeed sent by the owner of the private key and that the message has not been altered.

C. Smart contracts

1. Smart contracts are self-executing contracts where the terms of the contract are written directly into law.

• The terms of the contract are self-implemented and enforceable upon fulfillment of predetermined conditions, without the need for intermediaries.
• Smart contracts are typically implemented on blockchain platforms that support smart contract functionality, such as Ethereum.

Execution:

• Smart contracts are executed by blockchain network nodes according to rules defined in their code.
• Once implemented, the code of the smart contract is immutable and transparent, which means it cannot be changed or modified, and its validity is transparent to all participants in the network
• Smart contracts can interact with blockchain data, trigger actions, and transfer digital assets based on pre-defined conditions.
• Can be used to create functional systems, such as financial transactions, supply chain management, voting systems, and decentralized applications (DApps).

Steps in Blockchain Business

A. Starting the project:

1. The participant initiates a transaction by creating a digital message containing information such as the address of the sender, the address of the recipient, the amount of cryptocurrency or assets to be issued, and any other required data a the story seeks him to be .

2. The sender creates a digital signature by signing the transaction with his private key, ensuring the authenticity and authenticity of the transaction.

3. Once signed, the transaction is sent to the network for processing.

B. Research conducted:

1. Upon receipt of a transaction, network nodes verify its authenticity and integrity using a digital signature using the sender’s public key

2. The nodes also verify that the sender has sufficient funds or licenses to perform the transaction and that the transaction complies with the rules and regulations of the network.

3. The validated services are then propagated to other nodes in the network for further validation.

C. Recordings in one volume:

1. The acknowledged transactions are collected in a block, along with a timestamp and a description of the hash of the previous block.

2. The hashed segment data is generated using cryptographic algorithms, including the transaction information to create a unique identifier for the segment.

3. The hash portion is added to the blockchain ledger, creating a timeline and immutable record of transactions.

D. Changes in Blockchain:

1. Before adding a new block to the blockchain, there is a consensus check of the network nodes’ consent and authentication

2. Proof of Work (PoW) In conceptual approaches, miners compete to solve complex mathematical puzzles to validate and build new blocks.

3. In proof-of-stake (PoS) consensus strategies, authenticators are selected to produce additional pieces based on the amount of cryptocurrency they hold and are willing to “put a stake” as collateral.

4. Once consensus is reached, the new block is added to the blockchain and the transaction is considered confirmed.

5. The addition of a block to the blockchain is propagated to the network, and all nodes update their copies of the blockchain accordingly.

6. The transaction is now finalized and cannot be changed or rolled back, ensuring the integrity and security of the blockchain ledger.

Security measures in blockchain

A. Constants:

• Immutability means that data cannot be changed or altered once it is recorded on the blockchain.

• Each block in a blockchain contains the cryptographic hash of the previous block, creating a chain of interconnected blocks.
