“We are excited to have Lionel Messi, the best football  player in the world as the global brand ambassador for Sirin Labs,” he said in the post. “We have identified the potential of blockchain technology and are developing SirinOS to improve the security and user-experience on the blockchain to encourage mass adoption.”

The company has developed an ultra-secure mobile phone using blockchain technology, which is a continuously growing list of computer records, called blocks, which are linked and secured using cryptography.

The company also tweeted the news, saying  that it is  “proud to announce our #official global brand ambassador, the GREATEST footballer on the planet – LEO MESSI. Let’s kick some goals together and bring #Blockchain technology to the mass market.”

There is a Sirin Labs research and development center in Tel Aviv, but the company has expanded globally to include a London site and a company headquarters in Switzerland.

The Argentinean football  star plays professionally for the Spanish team Barcelona. He has won the FIFA Ballon D´Or prize for the best football  player worldwide five times and often is considered one of the world’s greatest players of all time. He will be part of the Argentinean national football  team at the World Cup 2018 in Russia.

While on “peace tour” to Israel with members of the Barcelona team in August 2013, Messi visited the Western Wall in Jerusalem and met with Israeli leaders. In July 2013 he sent a message to the Argentinean Maccabiah team. One year later Messi supported a football  match organised by Pope Francis to promote peace between Israelis and Palestinians, but he did not play in the match due an injury.
