IBM to Use Proof-of-Work for Blockchain IoT Devices

IBM aims to patent a method for ensuring that IoT network can securely execute blockchain-based smart contracts

IBM explains in a patent application published Thursday, "one example method of operation may include determining a proof-of-work via a device and using a predefined set of nonce values when determining the proof-of-work, storing the proof-of-work on a blockchain, and broadcasting the proof-of-work as a broadcast message."

An IoT-focused blockchain network couldn't engage in the kind of competitive "mining" that powers the bitcoin network, largely because a smart toaster or lightbulb can't harness the power of a warehouse full of specialized computers. At the same time, a large-scale blockchain mine could conceivably have an easier time of attacking a network of IoT devices and, thus, potentially compromise it.

IBM's proposed solution wouldn't ditch bitcoin's proof-of-work system. Proof-of-work adds a block of data - transaction data, in bitcoin's case - to the blockchain by running it through a hash function. This is a simple process; the "work" comes from the requirement to obtain a hash that meets certain parameters, which calls for running the hash function again and again.

IBM envisions applying this invention to smart contracts, with use cases such as "peer to peer (P2P) energy networks, logistic networks, crowd-sourced weather networks, and the like."

We have recently reported that IBM cooperate with a consortium of gold and diamond companies in the jewelry supply chain to track engagement rings from the mine to the retail shelf via blockchain.

SEC to Accuse Veritaseum ICO of Fraud

SEC believes that project's tokensale, thru which it raised $14.8M back in 2017-2018 had a signs of scam and company misled the investors

The U.S. Securities and Exchange Commission (SEC) has sued New Yorker  and Veritaseum-related companies that have been caught by the agency in conducting an unregistered ICO with signs of fraud. It is reported by Cointelegraph.

According to documents published on the network, the SEC intends to hold Reggie Middleton accountable and immediately freeze the assets of Veritaseum Inc. and Veritaseum LLC.

The Commission claims that the defendants raised about $ 14.8 million through an initial coin offering (ICO) in 2017 - early 2018. At the same time, many investors were misled, as the company distorted information about the conditions of the token sale and deliberately hid some significant details.

The American regulator claims that the project still has about $ 8 million of illegally raised funds. According to the SEC, these assets must be frozen immediately.

Amid this news, the Veritaseum (VERI) rate has fallen by 70%. Now the coin is trading near the $ 5 mark, although at the beginning of 2018 its rate was approaching $ 500.

Veritaseum was created as a financial p2p platform, involving the movement of capital without traditional intermediaries. Also, VERI was positioned as a utility token for use in consulting services and access to various research works.

In 2017, Veritaseum blockchain startup fell victim to hackers, having lost $ 8.4 million from ICO investors.
