Bitfury successfully tests Lightning Network transaction using current Bitcoin protocol

The Bitfury Group, a leading full-service blockchain technology company, announced that its developers have successfully tested the Lightning Network on the main Bitcoin network.

Committed to the success of the Lightning Network and the wider Bitcoin ecosystem, Bitfury engineers have been conducting research and carrying out tests to perform Lightning transactions using the current Bitcoin protocol.

After much research, the Bitfury team succeeded in sending a real-time bitcoin transaction on the Lightning Network, which can be seen in a video demo.

Valery Vavilov, CEO of The Bitfury Group said:

“This is a major accomplishment by our technical team and an important step forward for the Lightning Network and the growth of Bitcoin.”

“The Lightning Network has the potential to solve Bitcoin’s scalability issue and provide instant payment functionality. By demonstrating that the Lightning Network can function now, Bitfury has cleared the way to increased transaction processing and further adoption of Bitcoin.”

For more than a year, Bitfury has been supporting the development and implementation of the Lightning Network. In July 2016, Bitfury released a white paper in collaboration with the Lightning Network team detailing the specifications for Flare, an algorithm developed to improve payment routing in the Lightning Network.

In September 2016, the Flare algorithm was successfully implemented and tested by ACINQ. Back in May, Bitfury successfully tested a Litecoin payment using its Lightning Network interface.

The Transaction

The software written by Bitfury developers is based on the LND protocol being developed by Lightning Labs. The link to Bitfury’s modified version can be viewed here.

The setup of the transaction involved three LND nodes, in which two nodes were connected to the third one by payment channels. To carry out the transaction, Bitfury developers first opened the payment channels.

Hashes of the funding transactions, which can be viewed in any Bitcoin explorer, are:


After opening the channels, Bitfury developers could make an indefinite number of transactions between the three nodes without fees, but made just two: one single-hop transaction and one
multi-hop transaction.

After completing the transactions, developers settled the payment channels by broadcasting the closing transactions on the Bitcoin Blockchain.

Hashes of the closing transactions are:
