Twitter co-founder and CEO Jack Dorsey has recently shown off a recently received Bitcoin Lightning Network full node he got from Casa, further showing the entrepreneur’s commitment to the flagship cryptocurrency and its layer-two scaling solution.

The node Jack Dorsey showed off on Twitter is one being sold by Casa for $300, that already comes with a gold membership on the company’s platform, and is already pre-synced to make it easier to set up.

The Casa Node, a plug-and-play solution, is built with Raspberry Pi 3B+ and comes with cables that help users get going. Running a full Bitcoin node helps validate the cryptocurrency’s blockchain, contributing to its decentralization and security.

Since Casa’s node allows Dorsey to participate in the Lightning Network (LN), the cryptocurrency’s layer-two scaling solution, the entrepreneur may also contribute to its liquidity. The LN’s capacity surpassed 50 BTC late last year, and is now over 733 BTC.

Dorsey, who’s also the CEO of Square, the company behind the Cash app, which lets users buy and sell bitcoin, has notably invested in the LN last year, helping it become a reality. Last month, he backed a ‘trust game’ based on it that saw users pass a ‘torch’ worth hundreds of thousands of satoshis to one another.

As CryptoGlobe covered, data from cryptocurrency analytics platform Data Light has shown that 74% of all Bitcoin nodes are located in only 10 countries, with the US alone having over 2,600 nodes.

Behind the US are Germany and France, with 2,016 and 698 Bitcoin nodes respectively. The countries with the greatest Bitcoin nodes per capita were Singapore and the Netherlands, at 17,700 and 32,000 citizens per node.
