Microsoft has announced a new Plugin for Office10 that makes it possible to store a hash of documents on the blockchains of Bitcoin and Ethereum Classic. With this, you can prove the authenticity of any document – without the need for a notary or a lawyer. Microsoft has potentially created Bitcoin’s first non-monetary killer app.

The new notary app for Outlook is not Microsoft’s first venture into the world of blockchain technology. Microsoft has also developed the Azure Blockchain-as-a-Service (BaaS) platform, which allows companies to collaborate by experimenting with new business processes using Microsoft’s cloud-based distributed ledger platform. Microsoft has also joined the Enterprise Ethereum Network to develop blockchain solutions together with leading financial institutions and has teamed up with startup Tierion to secure identities in digital format on the blockchain. 

The head of the Large Bitcoin Collider, an attempt to crack bitcoin private keys, also spoke to BTCManager: “Yes, I own some bitcoin, and the LBC does not change that. What I personally would not do any longer is to store large sums of bitcoin on a single address. By doing so, you take risks, independently of the LBC. I would not trust a chain of 160 ones and zeros with something like $100 million.”

Litecoin trading volumes have grown over the past week, as SegWit looks almost certain to be locked-in. The price of litecoin moved higher and posted a fresh high just below our target at $17.387 as stated in our previous cryptocurrency market outlook, at $17.353 on the Poloniex exchange. The market has since retreated to $16.00, but the target at $17.387 remains valid while a key support lies at $15. The price of bitcoin has also drifted higher over the week, flirting with the $1250 handle at the time of writing.

This week’s review is compiled from contributions by Alex Lielacher, Christoph Bergmann, and Jamie Holmes.

Be Your own Notary with the new Blockchain Plugin for Microsoft Office10

The new blockchain plugin for Office10 uses the publicly available API of blockchain startup Stampery. The add-on for Outlook creates a hash of something like an e-mail, sends the hash to a Microsoft Azure server, and this server give the hash to the server of Stampery, where it is put in the blockchain of both Bitcoin and Ethereum Classic. The user meanwhile keeps a copy of the hash and likely receives an ID of the transactions.

“Nobody Knows. Some do Say because they are Horrified by the Alternative…”

The Large Bitcoin Collider (LBC) tries to break Bitcoin addresses through a brute force attack. In the few past weeks, the project announced their first success. In an interview with BTCManager, Rico, the head of the LBC, explains that he has found a way to break into bitcoin addresses successfully and recommends not to store large amounts of bitcoin in one single wallet as they are not impossible to break into.

The Russian political party Partiya Rostiya has launched the world’s first blockchain-based social project by issuing its cryptocurrency called Upcoin in collaboration with the blockchain startup Waves to promote blockchain technology awareness and to incentivize its party members to engage in more community-based activities.

Using the Waves platform, ten million digital Upcoins were created. These coins are readily available for people who sign up on the projects portal Ludirosta.
