Where do bitcoins come from?With paper money, a government decides when to print and distribute money.Bitcoin doesn't have a central government.With Bitcoin, miners use special software to solve math problems and are issued a certain number of bitcoins in exchange.This provides a smart way to issue the currency and also creates an incentive for more people to mine.Bitcoin miners help keep the Bitcoin network secure by approving transactions.Mining is an important and integral part of Bitcoin that ensures fairness while keeping the Bitcoin network stable, safe and secure.Currently, based on (1) price per hash and (2) electrical efficiency the best Bitcoin miner options are: AntMiner S7 4.73 Th/s 0.25 W/Gh 8.8 pounds $479.95 0.1645 AntMiner S9 13.5 Th/s 0.098 W/Gh 8.1 pounds $1,987.95 0.3603 Avalon6 3.5 Th/s 0.29 W/Gh 9.5 pounds $499.95 0.1232 Bitcoin mining is the process of adding transaction records to Bitcoin's public ledger of past transactions or blockchain.

This ledger of past transactions is called the block chain as it is a chain of blocks.bitcoin kaufen und verkaufenThe block chain serves to confirm transactions to the rest of the network as having taken place.bitcoin store promoBitcoin nodes use the block chain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.bitcoin trade scriptBitcoin mining is intentionally designed to be resource-intensive and difficult so that the number of blocks found each day by miners remains steady.bitcoin price projectionsIndividual blocks must contain a proof of work to be considered valid.bitcoin fix sees delays

This proof of work is verified by other Bitcoin nodes each time they receive a block.bitcoin sicher kaufenBitcoin uses the hashcash proof-of-work function.litecoin пулThe primary purpose of mining is to allow Bitcoin nodes to reach a secure, tamper-resistant consensus.illuminati behind bitcoinMining is also the mechanism used to introduce Bitcoins into the system: Miners are paid any transaction fees as well as a "subsidy" of newly created coins.bitcoin send money apiThis both serves the purpose of disseminating new coins in a decentralized manner as well as motivating people to provide security for the system.Bitcoin mining is so called because it resembles the mining of other commodities: it requires exertion and it slowly makes new currency available at a rate that resembles the rate at which commodities like gold are mined from the ground.

A proof of work is a piece of data which was difficult (costly, time-consuming) to produce so as to satisfy certain requirements.It must be trivial to check whether data satisfies said requirements.Producing a proof of work can be a random process with low probability, so that a lot of trial and error is required on average before a valid proof of work is generated.Bitcoin uses the Hashcash proof of work.Bitcoin mining a block is difficult because the SHA-256 hash of a block's header must be lower than or equal to the target in order for the block to be accepted by the network.This problem can be simplified for explanation purposes: The hash of a block must start with a certain number of zeros.The probability of calculating a hash that starts with many zeros is very low, therefore many attempts must be made.In order to generate a new hash each round, a nonce is incremented.See Proof of work for more information.The Bitcoin mining network difficulty is the measure of how difficult it is to find a new block compared to the easiest it can ever be.

It is recalculated every 2016 blocks to a value such that the previous 2016 blocks would have been generated in exactly two weeks had everyone been mining at this difficulty.This will yield, on average, one block every ten minutes.As more miners join, the rate of block creation will go up.As the rate of block generation goes up, the difficulty rises to compensate which will push the rate of block creation back down.Any blocks released by malicious miners that do not meet the required difficulty target will simply be rejected by everyone on the network and thus will be worthless.When a block is discovered, the discoverer may award themselves a certain number of bitcoins, which is agreed-upon by everyone in the network.Currently this bounty is 25 bitcoins; this value will halve every 210,000 blocks.See Controlled Currency Supply.Additionally, the miner is awarded the fees paid by users sending transactions.The fee is an incentive for the miner to include the transaction in their block.In the future, as the number of new bitcoins miners are allowed to create in each block dwindles, the fees will make up a much more important percentage of mining income.

“Avan panthai pidikkavillai, panthe daan avanai pidittade,” thundered Badava Gopi in the hit Tamil flick ‘Chennai 600028’.Translated into English, it would mean — the player didn’t catch the ball, the reverse happened.The 2007 movie offered a ringside view of Tamil commentary in local competitions, but regional commentary in the state had its genesis in the late 1970s.A Test match those days would be held during Pongal and All-India Radio (AIR) pioneered the concept of Tamil audio commentary for these games.One could hear V Ramamurthy, an accomplished IAS officer, providing listeners with the latest action from the ground.Soon, the AIR Tamil commentary team was joined by former Test cricketer C Rangachari, Abdul Jabbar, K S S Mani, P Sivaramakrishnan and P Ganesan among others.These commentators aired their views not only on international fixtures in the city but also at Ranji Trophy games featuring Tamil Nadu and even during the Buchi Babu tournament.This was one of the first attempts made to take the sport to the Tamil masses.

Over the years, Tamil commentary has been embraced by other sporting disciplines such as kabaddi and football during local and corporate tournaments.Nanee Sathyanarayan, a senior commentator feels commentary in local tournaments has an earthy flavour to it.“There is a humour element associated with Tamil commentary at local competitions.In such events, no professionals are involved in the commentary unlike a television channel setup where the people roped in are experienced players and commentators who are well-versed with the language and the game,” Nanee says.In the local games, the commentators are mostly people who have a command over the language and an impeccable sense of humor.Whilst local tournaments revel in their own brand of commentary in the state, television channels — over the past decade-and-half — have joined the bandwagon and tasted success.Tournament-specific Tamil commentary has been provided by channels such as ESPN, Sun TV, Neo Sports and even Zee in the past.

Dr Sumanth C Raman, a renowned anchor with extensive commentary experience in both English and Tamil, believes there is immense potential in this medium.But, he has a word of caution when it comes to the usage of humor in commentary in the vernacular language.“While a healthy dose of humour may be needed, the commentary needs to be as professional as English commentary is,” he says.Nanee says television channels have got smarter over time with regards to the content that gets aired.“If you listen to the Tamil commentary on Star Sports, it clearly has a healthy humour.As commentators, it is our duty to engage with our viewers.We don’t want to crack jokes just for the sake of it but at the same time, we don’t intend to make things too serious as well,” he adds.A significant difference in today’s Tamil commentary vis-a-vis the yesteryears have been in the choice of words.“We use words that a true blue Tamilian uses at home or with friends.I feel it’s the best way to connect with our audience,” says former India batsman Hemang Badani, who is one among the Tamil commentators of recently launched Start Sports Tamil.

As in the case of English commentators, the men behind the microphones have their favourite lines in Tamil too.“Arpudamana shot (great shot) is something I usually use,” says Hemang.His fellow commentator RJ Balaji prefers to go with a phrase that the late Tony Greig made his own.“Growing up, I always enjoyed listening to his (Tony Greig) commentary.And his line — ‘Oh, it’s all happening here’ is something I enjoy saying often,” Balaji says.Balaji and Srikkanth share a great rapport and that comes through when they air their views.“Srikkanth gave me a lot of freedom to express myself, and our commentary together is a reflection of that,” says Balaji.With Balaji in the house, there can be no dearth of quirky moments.“Once in the commentary box, I mistook Hemang for Hrishikesh Kanitkar and asked him about the boundary he had scored to win the match against Pakistan many years ago.I kept saying it on many occasions until Hemang corrected me,” says Balaji.For the broadcasters like Star TV India, launching channels like Star Sports Tamil is an attempt to bring fans closer to the sports.
