In this post, we look at what makes blockchains — as applied in the cryptocurrency sector — impervious to security breaches. This eliminates a single point of failure. Each transaction is called a block, and the interconnection of several transactions becomes a blockchain.

Notably, a block has cryptographic elements that make it unique. A network's hashing algorithm determines the details. By making it hard to reverse the hashed value, a transaction becomes inflexible.

Each block in a chain contains a specific set of data from the previous block. Therefore, even if a malicious actor reverse-engineers the hash, the resultant block would be out of sync with the rest of the blocks since it will have a different hash output, thus causing the system to reject it. Another reason why it's even harder to hack a blockchain is that in case the block being re-hashed is at the middle of the chain, the attacker would have to re-hash previous blocks to align their historical stamp with the new block.

In PoS-based systems, stakes determine the strength of the network. To elaborate, this means those users who have delegated or actively locked their native blockchain assets to participate in transaction processing and finding new blocks.

On such systems, an attack occurs when a hacker controls a majority of the stake. Conversely, when the blockchain participants find out you own a majority of the coins, they will likely sell their holdings, thereby crashing the market with excess supply. So far, nobody has single-handedly hacked a blockchain. Instead, it's usually a group of malicious actors or the core dev team that collaborate to breach a blockchain's security. However, as blockchain platforms get stronger through an increase of nodes or stakers, the possibility of hacking a decentralized network is increasingly moving towards zero.

In addition, newer blockchain systems use academically-proven techniques that would need highly-specialized quantum computers to hack. CoinMarketCap News. Why Nobody Can Hack a Blockchain. Table of Contents. What Makes a Blockchain Withstand Hacks? Answer: Hash Rate. By Werner Vermaak. Created 1yr ago, last updated 2mo ago.

A common mistake that new cryptocurrency investors make is to confuse the hacking of a blockchain with that of a digital exchange. Whereas unfortunately centralized digital exchanges get hacked more than they should, decentralized blockchain hacks are very rare, as they are hard to achieve and provide little incentive to carry out.

The blockchains behind most cryptocurrencies are peer-to-peer P2P , open-source and public, allowing everyone with the right equipment and knowledge to peek in under the hood. This is important to foster transparency and attract buyers. A blockchain comprises different technological mechanisms working together towards a common goal. For instance, there are consensus mechanisms such as proof of work PoW and proof of stake PoS that protect the network by mitigating cyber-attacks from hackers.

The architecture of a blockchain determines how the nodes cooperate in verifying a transaction before being committed to the protocol. This becomes prohibitively expensive at a certain point. Therefore, considering the size of established blockchains like Ethereum and Bitcoin , such a scenario is nearly impossible. For reputable networks like the evolving Ethereum 2.

Good question. It boils down to the strength of a network. The Ethereum Classic network uses the PoW consensus algorithm. Although Bitcoin uses the same algorithm, ETC has a much lower number of nodes and miners securing the system. Thus, it has lesser processing power, making it easier for an attacker to take control. ETC has a hash rate of 1.

Ramesh also informed that he had hacked into the Karnataka government's eProcurement site in A year-old accused in Karnataka's alleged Bitcoin scam has informed the police that he had twice hacked Bitfinex exchange during his stay in Netherlands. The exchange was hacked twice, and I was the first person to do so. The second instance was a simple spear-phishing attack which led to two Israeli hackers working for the army getting access to the computers of one of the employees, which gave them access to the AWS cloud account," Ramesh said in his statement to the police. Explaining how he managed to hack the bitcoin exchange, he said, "I exploited a bug in the data centre which gave me KVM Kernel-based virtual machine access to the server. I rebooted the server into GRUB mode, reset the root password, logged in, and reset the withdrawal server passwords and routed the money via bitcoin to my bitcoin address. He said, "I did not save anything.

By Matthew Sparkes. Bitcoin could one day be threatened by quantum computers — but not yet. Quantum computers would need to become about a million times larger than they are today in order to break the algorithm that secures bitcoin , which would put the cryptocurrency at risk from hackers. The bitcoin network is kept secure by computers known as miners that use a cryptographic algorithm called SHA, which was created by the US National Security Agency.

Cryptocurrency is a type of digital currency that generally only exists electronically.

SEC will teach you the essential topics of blockchain and smart contract technology. The course takes a detailed look at the cryptography and transactions behind blockchain and provides the hands-on training and tools to deploy, audit, scan, and exploit blockchain and smart contract assets. In , an anonymous author, under the pseudonym Satoshi Nakamoto, published a white paper outlining a public transaction ledger for a decentralized peer-to-peer payment system entitled Bitcoin: A Peer-to-Peer Electronic Cash System, which is regarded as the "birth" of blockchain. Since then, the use of blockchain has evolved beyond its original implementation as a cryptocurrency. It has gained momentum in recent years, being adopted by some of the largest organizations in the world, including IBM, Amazon, PayPal, Mastercard, and Walmart.

Our Insights

Bitcoin literally jolted the whole currency market and definition of money itself. This was a fascinating concept thbat was brought about by Satoshi Nakamoto, a pseudonym. BTC introduced the world of cryptocurrency and coined the idea of crypto trading. While a few thinkers responded positively to BTC and launched various altcoins and stablecoins to compete with the first large crypto coin, others raised concerned on the legitimacy and security aspect of the digital asset.

Cryptocurrency has been around since , when Bitcoin and the technology that records its transactions, blockchain, were invented. In the last year Bitcoin has become extremely popular in the media and many other kinds of cryptocurrency have started or grown, such as Ethereum. Your cryptocurrency is kept in a digital wallet and is accessed by having a private key, like a very strong password, to approve buying and selling. It gives them free reign to sell or exchange the bitcoin to someone else.

A smart contract is a way to handle business transactions to ensure they are secured, accurate, fast, and cost-effective—all without involving a third party, such as a bank. CEO confirms hundreds of accounts were hacked, hedges on other details

He is also a member of CMT Association. Blockchain, the underpinning technology that maintains the transaction ledger for bitcoin, has revolutionized the way information can be shared on the internet because the data can't be altered or deleted. Bitcoin is probably the most widely known application of blockchain, however that's just the beginning. Blockchain technology can be used to reduce costs, speed up transactions, and improve data security for financial institutions , health care providers, businesses, and more. That's good news for consumers and investors. Although blockchain technology hasn't yet been widely adopted, it has the potential to dramatically change the way we do business by offering a trusted, cryptographic system for exchanging information. Blockchain gets its name from the way in which it stores transaction data—in blocks linked to form a chain.

Blockchain is becoming a legitimate disruptor in a myriad of industries. The technology can revolutionize government , finance , insurance and personal identity security , among hundreds of other fields. We've rounded up 37 interesting examples of US-based companies using blockchain.
