Investment in bitcoin brought MicroStrategy $ 100 million

Analytical software provider MicroStrategy's Bitcoin assets have risen by almost $ 100 million over the past two months.

In August and September, the company invested $ 425 million in reserve assets in the first cryptocurrency.

Now the cost of investments has exceeded $ 523 million, according to the Bitcoin Treasuries website.

Analyst Kevin Rook noted that MicroStrategy's net profit in the last 3.5 years was only $ 78 million, while the profit from investments in Bitcoin in 2.5 months reached $ 100 million.

Since the first purchase of the cryptocurrency, the company's capitalization has grown by 29.4%, to $ 1.7 billion.

Celsius and Horizen Develop Lending Transparency System

The company will conduct a series of experiments over the next few months to test the decentralization of some of its operations, according to Celsius. Celsius CTO Nuke Goldstein said:

“The biggest problem with DeFi is transparency. How can we prove to the world the accuracy of the numbers we are reporting? "

A pilot project to test the proof-of-reserve concept will take the information that appears on the Celsius website and feed it to the Horizen sidechain rather than Celsius's internal servers.

The app will first display customers' total assets by coin type and will eventually transfer Celsius transaction data encrypted with the Horizen zero knowledge proof suite.

The co-founder of Castle Island Ventures and CoinMetrics, Nic Carter, has previously described the concept of proof of reserves on numerous occasions and has encouraged crypto depository platforms to implement it. He said:

“Since I've never seen a lender implement proof of reserves before, it's hard to imagine what Celsius is trying to do. Zero-knowledge proofs for PoR are familiar to me, but I've never seen their implementation. "

The Celsius CTO said the full implementation would automate the tracking of reserves directly from the blockchain and preserve the privacy of individual accounts so that data would not be vulnerable to reverse engineering.

Goldstein added that the company will initially offer these solutions as part of the retail portion of its loan portfolio. Celsius will also conduct proof-of-concept hackathons in its community.

“We're going to bring ideas and technologies to the point where we can share them with the community and say, 'Try to find vulnerabilities and weaknesses in them. If you find something, we'll pay you, ”Goldstein said.

However, he said, it will be years before customers can take advantage of the technology. Recall that in the spring, the Celsius Network began to cooperate with the supplier of oracles Chainlink to decentralize the flow of quotes when calculating interest rates on loans in cryptoassets.
