Ethereum: a technical explanation of Bitcoin’s cryptography science

Bitcoin is usually misunderstood as a simple digital currency, but its underlying architecture depends on advanced cryptographic techniques to ensure safety, scalability and reliability. In this article, we will deepen the technical aspects of Ethereum’s cryptography science, exploring how it works to make it robust, reliable and scalable.

What is cryptography?

Encryption is the safe communication process between the parts using math algorithms and protocols to protect data from interception, tampering or spying. The term “cryptography” comes from the Greek words “kryptos” (secret) and “graphens” (written), and has existed since the sixteenth century.

Bitcoin cryptographic architecture

Bitcoin uses an open source decentralized protocol that depends on cryptographic algorithms to protect transactions, control new units and regulate the network. The main components of Bitcoin’s encryption architecture are:

• Hash Functions: Hash functions are unidirectional reversible transformations that map input data for fixed size output data. In Bitcoin, hash functions are used to create exclusive digital signatures for transactions.

• Digital Subscriptions : Digital signatures are mathematical representations of the content of a transaction that proves the identity and authenticity of the sender. In Bitcoin, digital signatures are created using the Digital Curve Digital Signature Algorithm (ECDSA).

• In Bitcoin, public key encryption is used to change keys between customers and us.

• Blockchains : Blockchains are decentralized and distributed systems that record transactions in a block sequence. Each block contains an exclusive identifier, transaction data and an anterior block cryptographic hash.

Ethereum cryptographic science

Ethereum is built on Bitcoin’s blockchain architecture, but has several new features to improve safety, scalability and usability. Some -chave aspects of Ethereum’s cryptography science include:

• They are a crucial component of Ethereum, allowing decentralized applications (Dapps) that are executed on the network.

• Proof of Participation (POS)

  : POS is a consensus algorithm used to validate transactions and create new blocks. It is more efficient in terms of energy than traditional work proof algorithms (POW), making it suitable for high traffic networks like Ethereum.

• This feature is essential for safe and anonymous transactions.

Cryptographic concepts -chau

To understand the intricacies of Ethereum’s cryptography science, we need to understand various concepts -chave:

• Cryptition : Cryptography is a process of conversion of simple text into ciphered text to protect them from unauthorized access.

• Decritional : Decriptography is the opposite of encryption; It involves reversing the encryption process to recover original simple text data.

• Hash Functions: Hash functions are used to create exclusive digital signatures and check data integrity.
