Each wallet also has a private key, which is similar to a password and can be used to access your wallet at any time. More commonly, the user will typically be given a seed phrase that encodes the same information as the private key. While the private key is a mathematical number, most users never handle this number. Each digital wallet has a public bitcoin address that users can use to send and receive coins between wallets and bitcoin exchanges.
Below, we look at the top three crypto mining stocks with the best value, the fastest growth, and the best performance. The market performance numbers above and all statistics in the tables below are as of Sept.
Each second NTime increases by one. "NTime rolling" is a getwork parameter indicating how many seconds forward a miner can still consider this getwork valid (by incrementing NTime locally). It is one element on the block header. NTime is the integer timestamp in seconds.

The blockchain is a decentralised, distributed public ledger that records transactions anonymously and securely. The decentralised nature of blockchain technology means that Bitcoin has no central point of control, as with most traditional currencies, and is sustained by individuals in the widespread cryptocurrency community. This creates a trustless payment system, where parties participating in bitcoin transactions can be sure of the information displayed on the blockchain. By recording all transactions made within the cryptocurrency network, blockchain technology removes the need for a middle-person like a central bank, payment app such as PayPal, or any other central authority.
This process creates a new block on the blockchain where transactions are recorded, verified and saved. Unlike fiat currencies, bitcoins are not physical objects. Once 21 million coins have been mined, we won’t be able to make anymore! Bitcoin miners are rewarded for this service with bitcoins and transaction fees. Part of bitcoins value is created through supply and demand, as there is a limited number of bitcoins to be mined. Instead, they exist in the virtual world as snippets of code. New bitcoins, or BTC
, are created through a process called bitcoin mining, where powerful computers solve complex equations. This is set to occur sometime in the year 2140 and it’s what sets bitcoin apart from other popular cryptocurrencies such as Ethereum and Litecoin.
This was a key moment in the crypto space, and has since gained near-mythical status, highlighting the importance of securing your bitcoins in a bitcoin
wallet. When their coins are not being used, people keep bitcoins in virtual wallets for safety. The most famous example is the Mt Gox hack of 2014, when thieves stole more than 700,000 bitcoins. Sometimes hacks occur when bitcoins are not stored properly.
Such mining difficulty adjustments are highly correlated to changes in the mining hashrate — the level of computing power used during mining. The mining difficulty reading is now at 27.69 trillion at a block height of 745,920, the lowest level since March. Bitcoin’s hashrate dropped to 193.2 exahashes per second on Thursday on a seven-day average from a record high of 231.4 exahashes on June 12, Blockchain.com data showed. Bitcoin’s price stood at US$23,039 at 11 a.m. Friday HKT, up 0.7% in the past 24 hours, according to data from CoinMarketCap. Bitcoin mining difficulty is a measure of how hard a miner would have to work to verify transactions on a block in the blockchain, or "dig out" Bitcoins. The difficulty level, which undergoes adjustments about every two weeks, reached a record high of 31.25 trillion on May 11.
An example: bitcoin A pool provides a 100MH miner a block header containing the current ntime, a nonce range of 0 to 2^32 (full nonce) and an NTime Rolling value of 40. Once it has incremented NTime 40 times it must request new getwork. The miner would hash until the local time increments 1 second (roughly 100 million hashes) then it would increment NTime value and continue to hash for btc another 1 second (roughly 100 million more hashes).
In your example I speculate that Slush looked at the pool logs and determined that some miners were requesting work "too often" indicating they were ignoring or incorrectly using NTime Rolling value. Obviously a pool operator would want all miners to use latest protocols such as NTime rolling, and Long Polling as it allows a pool server to handle a higher throughput with same amount of hardware, bandwidth and other resources. Proper use of NTime rolling improves pool efficiency by reducing number of getworks per share.
