Bitcoin’s Security and Hash Rate Explained

Bitcoin’s Security and Hash Rate Explained
As the Bitcoin hash rate reaches new all-time highs, there’s never been a better time to discuss blockchain security and its relation to the hashing power and the Proof of Work (PoW) that feed the network. The Bitcoin system is based on a form of decentralized trust, heavily relying on cryptography. This makes its blockchain highly secure and able to be used for financial transactions and other operations requiring a trustless ledger.
Far from popular belief, cryptography dates back to thousands of years ago. The same root of the word encryption — crypt — comes from the Greek word ‘kryptos’, meaning hidden or secret. Indeed, humans have always wanted to keep some information private. The Assyrians, the Chinese, the Romans, and the Greeks, they all tried over the centuries to conceal some information like trade deals or manufacturing secrets by using symbols or ciphers carved in stone or leather. In 1900 BC, Egyptians used hieroglyphics and experts often refer to them as the first example of cryptography.
Back to our days, Bitcoin uses cryptographic technologies such as:
  1. Cryptographic hash functions (i.e. SHA-256 and RIPEMD-160)
  2. Public Key Cryptography (i.e. ECDSA — the Elliptic Curve Digital Signature Algorithm)
While Public Key Cryptography, bitcoin addresses, and digital signatures are used to provide ownership of bitcoins, the SHA-256 hash function is used to verify data and block integrity and to establish the chronological order of the blockchain. A cryptographic hash function is a mathematical function that verifies the integrity of data by transforming it into a unique unidentifiable code.
Here is a graphic example to make things more clear:

– Extract from the MOOC (Massive Open Online Course) in Digital Currencies at the University of Nicosia.
Furthermore, hash functions are used as part of the PoW algorithm, which is a prominent part of the Bitcoin mining algorithm and this is what is of more interest to understand the security of the network. Mining creates new bitcoins in each block, almost like a central bank printing new money and creates trust by ensuring that transactions are confirmed only when enough computational power is devoted to the block that contains them. More blocks mean more computation, which means more trust.
With PoW, miners compete against each other to complete transactions on the network and get rewarded. Basically they need to solve a complicated mathematical puzzle and a possibility to easily prove the solution. The more hashing power, the higher the chance to resolve the puzzle and therefore perform the proof of work. In more simple words, bitcoins exist thanks to a peer to peer network that helps validate transactions in the ledger and provides enough trust to avoid that a third party is involved in the process. It also exists because miners give it life by resolving that computational puzzle, through the mining reward incentive they are receiving.

Logical proof that luke-jr is actively hostile to Bitcoin. A response to threats of algo change and associated nonsense.

To any casual reader that had an inkling of doubt that luke-jr is actively hostile to Bitcoin, I present to you a logical proof.
Here and elsewhere, he asserts that the Bitcoin mining algorithm now suffers from the same weakness as IP addresses in the Satoshi whitepaper, because Bitmain has a majority share of the market. Effectively, the argument is that hashpower representation has been subverted by a single interest, Bitcoin is already under a 51% attack, and the answer is to defensively fork to a new PoW algorithm. We are all fairly aware of his position and it is an internally consistent one. It is important, however, to fully articulate the entire argument rather than pick at the individual facets of it, because while the facets are logically sound, it is the premises that are being misrepresented - and I will go on to show that it is internally inconsistent for him to be ignorant of the misrepresentation and still be a Bitcoin user, and the only logical purposes his positions can serve, from his point of view, are with hostile intentions.
First, the core misrepresentation. Let us come back to the Satoshi whitepaper: Proof of Work is a demonstration of a scaled and maintained investment into the security of Bitcoin. As more investments into the decentralized mining network are made, by individual miners deploying hashpower, the system becomes increasingly difficult to subvert. More hashpower means more security, and this is a core fundamental of the functionality of Bitcoin as a fungible store of value. Proof of Work is the innovation that powers Bitcoin. The implementations and respect of, and consensus around, PoW are behavioral; but the idea - the system - is designed to be irreverent to human behavior, and rely only on PoW, and it does so spectacularly. As we say in the engineering field - people fail, systems don't.
Now, it's important to understand that PoW is more than just Proof Of Purchase From Bitmain. This is the misrepresentation at its core - luke implies that hashpower purchased from Bitmain is somehow a point of failure or centralization. This is wholly incorrect, but an easy assumption to overlook when one is presented with the argument in the manner luke prefers to frame it. Bitmain makes the money from the equipment, after all; but it's not the money made that matters to Proof of Work, it's the money spent.
You see, it's not Bitmain operating those miners, it's the purchasers - wide and varied as they are about the globe. Those purchasers are the ones that are invested into the system. Bitmain makes money - and indeed, that revenue model is dependent on growing investment in Bitcoin - but manufacturing equipment by itself does not represent an investment in Bitcoin's security. Mining equipment isn't producing blocks and securing the network until powered and connected to the mainnet - and guess who invests in that? Not Bitmain. Bitmain has no influence on the demand for its products - this is econ 101 guys - and Bitmain's product is mining equipment, not hashpower. Hashpower is produced by mining equipment when the cost of power is paid. You can borrow, buy, or rent the gear; but you always pay for the power - even when cloud mining. This is important because I want to come back to the original comparison between IP addresses and hashes.
IP addresses are very inexpensive to control. Once purchased, they can be freely assigned and used at minimal expense. This makes them a poor choice for security. Hashpower is very expensive to control. After setup, they are a constant maintenance expense and require a continuous investment to maintain. Their purpose is to produce blocks that come with rewards, and those rewards are in turn locked by the system for a short time - ensuring the miners' continued interest in securing their investment negates any potential benefit of, and punishes, hostile behavior. Remember: Proof of Work, not human behavior, secures Bitcoin. A block produced by a Bitmain miner - as well as one produced by any other computing device - is acceptable to the network regardless of the addresses that recover the coinbase reward.
Now note how hostile behavior is treated by the system. If Bitmain-sold hashpower were hostile, or somehow damaging the network, other miners can react appropriately by refusing their damaging blocks. After all, what damages one miner damages all miners, and they have a united interest in stopping it. (failure is not an option, as it renders miners' investments, and by proxy Bitcoin itself, worthless)
See, IP addresses don't have any of these benefits. A simple assertion is not enough; one must prove their vested interest in the security of Bitcoin in order to secure Bitcoin. Our tough customer here either knows this fact, and is intentionally ignoring it when crafting his deceptive arguments, or is genuinely ignorant about the fundamental structure of Bitcoin's security model. If the former is true, his mendacity is a hostile attack on Bitcoin; if the latter is true, and he honestly believes Bitcoin is already compromised, he is not using Bitcoin because he considers it to be insecure - and is thus not a Bitcoin user.
Although, the second option really isn't an option. Clearly, he's fully aware of the technical aspects of the issue; he knows what a hash function is, he knows what a cryptographic proof is, and he understands the process by which blocks are produced. Ignorance of the security model that is serviced by these features is inexcusable at this point - if, by some miracle of human stupidity, he really believes Bitmain somehow controls Bitcoin and yet he controls funds by private key, how can he be trusted at all - for that matter, how could he be trusted if he doesn't? No matter the perspective, his insistence on the position is intent to obstruct. There is no purpose these statements can serve that is beneficial to luke himself or to Bitcoin, even placing him in the position of devil's advocacy for benefit, unless he is personally damaged by forward progress within Bitcoin. He is either obstructing with the intent to damage, or obstructing with the intent to resist progress. Therefore, he can only be actively hostile to Bitcoin in order to produce these statements, regardless of whether they are intentional misrepresentation or misguided assertions.

My experience bitcoin mining in 8 months

I will not describe the charms and shortcomings of service that I've used, you can read one review here or on any other website. Surely if you are on this post - about bitcoin mining you already have some idea and are more likely to find real numbers about it. Well, I have them.
I have been using Hashflare since September 2017.
SHA-256 is Bitcoin's mining algorithm, currently the most profitable of the available algorithms. The most interesting here, of course, is the colossal growth of the bitcoin rate, which has inflated the payback to the skies, 500-600% per year.
The second important point I want to draw your attention to is the daily Hashflare commission. On average, it takes 20-30% of your income. Why is it important to take it here? Yes, because in the reports on profitability in the Hashflare they show the figure without taking into account the commission, that is, it is noticeably overestimated.
The next one is Scrypt, this is the mining Litecoin algorithm. But Hashflare decided not to bother and enigmatic lightcoins convert themselves into bitcoin, and in bitcoins, they also pay a reward. To my taste, not the most honest moment in their work, because the leaps of growth of lightcoin on the yield of Scrypt is not particularly correlated.
Further - ETH. When I only bought power in HashFlare, ETH was the most profitable algorithm with a large margin from all the others.
Then there was the boom of GPU-mining in the world, the complexity of Ethereum network grew, which naturally affected the profitability. For a long time she was hanging out altogether below the 100% mark (that is, the cost of purchasing the contract did not repel herself). Now, with a new jump in the air, everything looks better.
In any case, the contract ETH has long been repulsed and now works in a plus. For all the time, 1.16 coins have been blamed.
I will not write any conclusions on whether to invest in cloud mining, whether it is worth it or it is a bubble that will soon burst. Everyone will make this conclusion by himself. I hope my post will help you in this.

When mining bitcoin, the hashcash algorithm repeatedly hashes the block header while incrementing the counter & extraNonce fields. Incrementing the extraNonce field entails recomputing the merkle tree, as the coinbase transaction is the left most leaf node. The block is also occasionally updated as you are working on it. The process is almost the same as Bitcoin mining, except you use the scrypt algorithm instead of sha256d. There are many other alternative cryptocurrencies to choose from.
