CoinSpark Launches Open Source Messaging Feature for Bitcoin

On Monday, CoinSpark released a new tool that allows bitcoiners to attach private messages to transactions.

Open sourced CoinSpark is a colored coin protocol that allows users to move assets around the blockchain much like Counterparty.

CEO Gideon Greenspan told Cointelegraph:

"The guiding principle of CoinSpark is that users can use a lightwight wallet on their computer. [...] [Both the sender and the recipient] can prove the message exists very easily without having to go to a notary, or without having to go to any kind of a central intermediary."

Oliver Janssens and Jim Harper Win Bitcoin Foundation Seats

The results of the Bitcoin election run-off are in, and Oliver Janssens and Jim Harper are the newest members of the Bitcoin Foundation board.

Janssens was the lead vote getter with 63 % of members approving his inclusion.  Harper came in second with 60 % of members approving his appointment.

Controversial figure Oliver Janssens made a clear claim on Twitter that he is determined to change the way the Bitcoin Foundation is currently operating. Last summer, Janssens put a US$100,000 bounty for a software that could replace the foundation's perceived control over Bitcoin development.

In contrast to Janssens, Harper is a more traditional candidate, and he would like to see the Bitcoin Foundation focus more on development.

Europe's Military Surplus Giant Now Accepts Bitcoin Payments

Taking their lead from a group of Bitcoin enthusiast customers and a “serious, public conversation” on Facebook, Europe’s military surplus giant, Varusteleka, now accepts bitcoin payments.

Using BitPay as a payment platform, the company now aims to ease that friction while opting to still receive the payments at their end in Euros.

Founder Valtteri Lindholm, told Cointelegraph:

"Payments within the euro zone are easy enough, but payments even to EU countries not part of euro are sometime so hard that no business gets done. Euro's not going to gain popularity anytime soon, so there is good room for Bitcoin."

Overall, BTC/USD continued in its uptrend with a weekly price increase of 7.9% .

USD trade volume remains stable, and the number of transactions per day continues its long-term raise, while oscillating between 88,000 and 109,000 transactions on a weekly basis.
