On 29 June 2020, the cryptocurrency trading platform StormGain announced the launch of its own Bitcoin cloud miner. To start mining, all you have to do is to install the StormGain mobile app and register an account. After that, tap 'Start Mining' in the Cloud Miner section, and the app will do the rest. On top of that, it's completely free!
[2]The source of the constants used in SHA-256 is interesting. The NSA designed the SHA-256 algorithm and picked the values for these constants, so how do you know they didn't pick special values that let them break the hash? To avoid suspicion, the initial hash values come from the square roots of the first 8 primes, and the Kt values come from the cube roots of the first 64 primes. Since these constants come from a simple formula, you can trust that the NSA didn't do anything shady (at least with the constants).[3]Unfortunately the SHA-256 hash works on a block of 512 bits, but the Bitcoin block header is more than 512 bits. Thus, a second set of 64 SHA-256 hash rounds is required on the second half of the Bitcoin block. Next, Bitcoin uses double-SHA-256, so a second application of SHA-256 (64 rounds) is done to the result.Adding this up, hashing an arbitrary Bitcoin block takes 192 rounds in total. However there is a shortcut. Mining involves hashing the same block over and over, just changing the nonce which appears in the second half of the block. Thus, mining can reuse the result of hashing the first 512 bits, and hashing a Bitcoin block typically only requires 128 rounds.[4]Obviously I didn't just have incredible good fortune to end up with a successful hash.I started the hashing process with a block that had already been successfully mined. In particular I used the one displayed earlier in this article, #286819.[5]Another problem with manual mining is new blocks are mined about every 10 minutes, so even if I did succeed in mining a block, it would be totally obsolete (orphaned) by the time I finished.Email ThisBlogThis!Share to TwitterShare to FacebookShare to PinterestLabels:bitcoin,math83 comments:Anonymoussaid...You're insane, but amazing.

- One small thing seems MISSING, remains not really clear. While page is titled "mining bitcoin...", then you have "mined a block", found a hash starting with zeroes...However - which of the numbers is the actual "coin" value that was mined / received, and how much of it?
Not long ago, I reviewed one of the most popular cloud mining platforms around: Genesis Mining. I tried to establish whether it would be a profitable investment instead of just buying Bitcoins and holding them (aka hodling).
HashFlare allows you to buy three different types of cloud mining power (also known as Hashrate). Sha256 is used mainly for mining Bitcoin, Scrypt can be used for mining Litecoin, and ETHASH is used for mining Ethereum and Ethereum classic.
I had an account and mining contract with them from 2018 and mined some bitcoin but when the price of bitcoin dropped they blocked my access to any withdrawal. I communicated with them in that time for several times but no response at all. Their website is still online and even I could access to my account some month ago, but no withdraw or action I could do on my account. I wrote to their support again and my email bounced back.. they are big scammers and stole every ones money but no one could catch them or no legal action against them.If anyone here claims that they could contact them and someone there helped them then they are scam too.
The current mishap appears to be at least the second time on record when HashFlare unilaterally altered its contractual commitments. 11 months ago, the platform switched all SHA-256 and Scrypt contracts from lifetime to one-year, on the grounds of global mining hardware scarcity. Obviously, many cloud miners did not appreciate this development and there was even a petition on Change.org with some 2,500 signatures.
On a simple level, hashrate is the way we measure how much computing power everyone around the world is contributing toward mining Bitcoin. Miners use their computer processing power to secure the network, record all of the Bitcoin transactions and get rewarded in bitcoin for their efforts.
The higher the hashrate of one individual Bitcoin mining machine, the more bitcoin that machine will mine. The higher the hashrate of the entire Bitcoin network, the more machines there are in total and the more difficult it is to mine Bitcoin.
Just like winning the lottery, the chances of picking the right hash is extremely low. However, modern bitcoin mining machines have a big advantage over a person playing the lottery. The machines can make an awful lot of guesses. Trillions per second. Each guess is a hash, and the amount of guesses the machine can make is its hashrate.
To understand cloud mining, you first need to understand how Bitcoin works. In the Bitcoin network, there are nodes that validate transactions. These validating nodes are what are referred to as miners in the industry. They received this title because of the energy they exert to maintain the validity of the blockchain. This energy consumption comes with a price tag. In this way, mining for Bitcoin is similar to mining for other precious assets. You need to invest time and resources which adds to the overall value of the asset.
Cloud mining attempts to solve some of the most pressing matters facing Bitcoin miners. Providing users the ability to lease or purchase mining equipment from a third-party cloud provider opened the door for universal participation. Anyone, located anywhere, could utilize a remote datacenter with shared processing power to earn some free Bitcoin.
Along with the elimination of financial barriers to adoption, cloud mining also does away with technical barriers. The early miners had to understand the coding of Bitcoin to download the blockchain and start verifying transactions. These demands increased when GPU and ASIC miners emerged. Now, there were professional manufacturers contributing to the sector.
Cloud mining eliminates electricity-based concerns from the mining equation. This elimination means that people who live in areas with extremely high electricity, such as certain islands in the Caribbean, can mine Bitcoin effectively. Keenly, cloud mining reduces your carbon footprint.
At the center of the cloud mining strategy are large data centers. These mega mining farms were purpose-built to save energy and deliver computational powers were needed. In a cloud mining scenario, you lease your hashing power and in return, you receive a certain amount of rewards per block. Since you have no access to the mining equipment, the data center is solely responsible for maintaining the equipment.
As with everything crypto, there are some caveats and risks that you need to be aware of before you invest in a cloud mining operation. Primarily, you should only work with reputable cloud mining pools to avoid scams.
A perfect example of a cloud mining scam playing out occurred this year. Just this week, the co-founder of an alleged mining scam was extradited from Panama to face charges in New York. According to court documents, Gutemburg Dos Santos promised wild rewards to his AirBit Club members. Of course, to get the best rewards, you needed to simply purchase the lifetime mining club package for $1000.

Before we begin...Before you read further, please understand that most bitcoin users don't mine! But if you do then this Bitcoin miner is probably the best deal. Bitcoin mining for profit is very competitive and volatility in the Bitcoin price makes it difficult to realize monetary gains without also speculating on the price. Mining makes sense if you plan to do it for fun, to learn or to support the security of Bitcoin and do not care if you make a profit. If you have access to large amounts of cheap electricity and the ability to manage a large installation and business, you can mine for a profit.
Sometimes you may want to mine a more volatile altcoin like MWC which is superior for scalability, privacy, anonymity and fungibility by utilizing MimbleWimble in the base layer.With mainnet launching in November 2019 it has risen from $0.22 to over $8.00 in its first two months.Another tool many people like to buy is a Bitcoin debit card which enables people to load a debit card with funds via bitcoins.What is Bitcoin mining?Bitcoin mining is a lot like a giant lottery where you compete with your mining hardware with everyone on the network to earn bitcoins. Faster Bitcoin mining hardware is able to attempt more tries per second to win this lottery while the Bitcoin network itself adjusts roughly every two weeks to keep the rate of finding a winning block hash to every ten minutes. In the big picture, Bitcoin mining secures transactions that are recorded in Bitcon's public ledger, the block chain. By conducting a random lottery where electricity and specialized equipment are the price of admission, the cost to disrupt the Bitcoin network scales with the amount of hashing power that is being spent by all mining participants.
To keep blocks coming roughly every 10 minutes, the difficulty is adjusted using a shared formula every 2016 blocks. The network tries to change it such that 2016 blocks at the current global network processing power take about 14 days. That's why, when the network power rises, the difficulty rises as well.Bitcoin Mining HardwareCPUIn the beginning, mining with a CPU was the only way to mine bitcoins and was done using the original Satoshi client. In the quest to further secure the network and earn more bitcoins, miners innovated on many fronts and for years now, CPU mining has been relatively futile. You might mine for decades using your laptop without earning a single coin. 2ff7e9595c
