Programmer Alex Bosworth paid his phone bill with Bitcoin Bitcoin While some may still be wondering what is Bitcoin, who created Bitcoin, or how does Bitcoin work, one thing is certain: Bitcoin has changed the world.No one can remain indifferent to this revolutionary, decentralized, digital asset nor to its blockchain technology.In fact, we’ve gone a long way ever since a Florida resident Laszlo Hanyecz made BTC’s first official commercial transaction with a real company by trading 10,000 Bitcoins for 2 pizzas at his local Papa John’s.One could now argue that While some may still be wondering what is Bitcoin, who created Bitcoin, or how does Bitcoin work, one thing is certain: Bitcoin has changed the world.No one can remain indifferent to this revolutionary, decentralized, digital asset nor to its blockchain technology.In fact, we’ve gone a long way ever since a Florida resident Laszlo Hanyecz made BTC’s first official commercial transaction with a real company by trading 10,000 Bitcoins for 2 pizzas at his local Papa John’s.One could now argue that Read this Term through a service called Bitrefill, according to Bitcoin.com.

Bosworth said that the test was fully real, but in a limited testing environment - meaning that the payment was made through a mainnet wallet, but the wallet is not yet widely available.

Bitrefill supports SIM card topups to 400+ mobile operators in 100 countries (or 600+ operators in 150 countries, depending on which page of its website you are reading). Payment can be made in Bitcoin or Litecoin.

As Bitrefill says on its website: "Sometimes during high load on the Bitcoin network, and especially with older wallets that don't use proper fee estimations, it can happen that transactions don't confirm for long time. This is an unfortunate consequence of how Bitcoin works."

This is exactly the issue that the Lightning Network was designed to solve. Its website explains that by circumventing the Blockchain Blockchain Blockchain comprises a digital network of blocks with a comprehensive ledger of transactions made in a cryptocurrency such as Bitcoin or other altcoins.One of the signature features of blockchain is that it is maintained across more than one computer. The ledger can be public or private (permissioned). In this sense, blockchain is immune to the manipulation of data, making it not only open but verifiable.

Making transactions off-blockchain is made possible by using the blockchain programme to create separate ledger entries, which are added to the main chain at a later point, when they are closed. As the website describes: "This is similar to how one makes many legal contracts with others, but one does not go to court every time a contract is made."

There are many altcoins which claim to solve the technical issues of Bitcoin. However, Bitcoin has continued to succeed because of perceived value - people generally prefer to pay with Bitcoin than an altcoin, because it is something that they recognise.

More importantly, the problems faced by Bitcoin are a result of its popularity, and it follows that a given altcoin will face similar issues if it becomes popular too. For example, Ethereum, heavily used for ICO generation and a certain cat game, saw its transaction fees rise from virtually nothing to a peak of $0.71 on December 14th, according to a report in Forbes.

Thus, a system like Lightning, which could improve the utility of Bitcoin itself, is very much in demand - Bitrefill actually began testing the network back in August. Now, following the successful transaction, CEO Sergej Kotliar said: "Everything is ready to go on our end, but we're not launching it yet until a Lightning wallet is released for general use on mainnet."
