#### Solution By Steps***Step 1: Immutable and Transparent Nature*** Blockchain's security primarily comes from its immutable (unchangeable) and transparent nature. Once data is recorded on a block and added to the chain, it cannot be altered without consensus from the network.***Step 2: Decentralization*** Another key aspect contributing to blockchain security is decentralization. Instead of a single central authority, blockchain relies on a network of nodes to validate transactions, making it more resilient to attacks.***Step 3: Cryptographic Hash Functions*** Blockchain uses cryptographic hash functions to secure data. These functions create unique, fixed-size outputs for any input, ensuring data integrity and authenticity.***Step 4: Consensus Mechanisms*** Consensus mechanisms like Proof of Work (used in Bitcoin mining) or Proof of Stake help validate transactions and secure the network against malicious activities.#### Final AnswerBlockchain's security primarily comes from its immutable and transparent nature, decentralization, cryptographic hash functions, and consensus mechanisms.#### Key ConceptBlockchain Security#### Key Concept ExplanationBlockchain security is ensured through immutability, transparency, decentralization, cryptographic hash functions, and consensus mechanisms like Proof of Work or Proof of Stake. These features collectively safeguard the integrity and trustworthiness of the blockchain network, making it resistant to tampering and fraud.
FAQs
Where does blockchain security come from? ›
Blockchain security is ensured through immutability, transparency, decentralization, cryptographic hash functions, and consensus mechanisms like Proof of Work or Proof of Stake. These features collectively safeguard the integrity and trustworthiness of the blockchain network, making it resistant to tampering and fraud.
Where does blockchain's security come from quiz answers? ›Blockchain's security primarily stems from its decentralized and cryptographic nature. Here are a few key points: 1. **Decentralization**: Blockchain operates on a distributed network of nodes, with no single point of control.
Where does blockchain's security come from Wikipedia? ›Blockchain systems use asymmetric cryptography to secure transactions between users. In these systems, each user has a public and private key. These keys are random strings of numbers and are cryptographically related. It is mathematically impossible for a user to guess another user's private key from their public key.
Does blockchain's security come from the concept of the design? ›Blockchain security is ensured through its immutable and transparent nature, design concept, and decentralized consensus mechanisms, safeguarding data integrity and preventing unauthorized alterations.
Where does blockchain's security come from mission Z? ›#### Solution By Steps ***Step 1: Identify Blockchain's Security Source*** Blockchain's security primarily stems from its design, which is immutable and transparent. This means once data is recorded, it cannot be altered without altering all subsequent blocks and the network's consensus, making it secure.
Where does blockchain come from? ›Blockchain has the potential to grow to be a bedrock of the worldwide record-keeping systems, but was launched just 10 years ago. It was created by the unknown persons behind the online cash currency bitcoin, under the pseudonym of Satoshi Nakamoto.
What is blockchain Quizlet? ›Blockchain is an encrypted, distributed database shared across multiple computers or nodes that are part of a community or system.
How does a hash help secure blockchain technology in EverFi? ›EVERFI Crypto Foundations Quiz Duestion 4 of 10 How does a hash help secure blockchain technology? Hashes do not allow any new blocks to be formed on a chain or new data to be added. Hashes block all changes. Hashes are like fingerprints that make each block of data unique.
What is the purpose of blockchain technology everfi? ›The Purposes of Blockchain Technology EverFi
Blockchain technology serves as a digital fortress in the realm of cyber e-commerce. Beyond its secure links, blockchain provides a multitude of purposes. From improving data security to facilitating the transmission of digital currency, its uses are wide and flexible.
Blockchain's security primarily comes from: B. Its immutable and transparent nature: 1. **Immutable Nature**: Once data is recorded in a block and added to the chain, it cannot be altered without changing all subsequent blocks, making it nearly impossible to tamper with past transactions.
What is the blockchain secured by? ›
Cryptography: Every transaction on the blockchain is secured with cryptographic principles, ensuring data integrity and authentication.
Where did information security come from? ›It is thought to have started in 1971 when Bob Thomas, a computer programmer with BBN, created and deployed a virus that served as a security test. It was not malicious but did highlight areas of vulnerability and security flaws in what would become “the internet.”
How does blockchain provide security? ›In most blockchains or distributed ledger technologies (DLT), the data is structured into blocks and each block contains a transaction or bundle of transactions. Each new block connects to all the blocks before it in a cryptographic chain in such a way that it's nearly impossible to tamper with.
What is the most secure blockchain? ›Ethereum is the best secure block chain based secure crypto currency platform.
Who invented blockchain? ›Blockchain began with a man named Satoshi Nakamoto, who invented Bitcoin and brought blockchain technology to the world back in 2009. Bitcoin aimed to be a viable alternative to fiat currency. A secure, decentralised, global currency that could be used as a medium of exchange.
Is blockchain under cyber security? ›Blockchain technology significantly enhances information security by effectively tackling concerns related to unauthorized access and the rising threat of cyberattacks.
What is the security architecture of the blockchain? ›The blockchain architecture is divided into three main components: the network, consensus, and application layers. The network layer is responsible for communication between nodes on the network. The consensus layer ensures that all nodes on the network agree on the state of the blockchain.
Is blockchain 100% safe? ›Blockchain is a secure, immutable ledger that enables the storage of information regarding digital asset ownership within an efficient consensus-based network. It ensures data remains decentralized and accessible to all users at any given time.
