A unique risk verification of smart contract developed by Fujitsu

Smart contracts can be automatically checked for vulnerabilities and point to the piece of the corresponding source code

Fujitsu Laboratories Ltd. and Fujitsu Research and Development Center Co., Ltd. today announced the result of its development process. The technology aims to identify vulnerabilities in smart contracts. The precursor of such technology is a special set of algorithms that identify risk-affected transaction sequences on Ethereum. With the aid of the algorithms 6 kinds of risks can be detected and neutralized thus greatly enhancing the development experience.

Those 6 threats go as follows: re-entrancy, authenticating the source of the transaction call, transaction uncertainty due to reliance on timestamp, transaction order transparency, divide by zero and call stack restrictions. Notably, authenticating the source of the transaction call and divide by zero were added as the direct result of the technology. The technology of detection includes virtual execution of transactions under different circumstances, comparison with code patterns of Ethereum that have fraudulent behaviour and checking whether access to transaction records of blockchain is granted or not.

Regarding the performance results, it is reported that while existing verification tools have 67% detection rate, Fujitsu technology had around 88~100%. The technology should contribute to the efficient application of blockchain technology into different areas. Lastly, Fujitsu plans to develop similar verification toolset for Hyperledger Fabric and methods of building secure systems via blockchain.

ICOs to Lose Popularity, Diar Research Say

Diar assumes that in the future unregulated ICOs won't attract significant attention

Although since the beginning of this year, ICO-startups have managed to raise over $ 12.2 billion, the November figure was only $ 65 million, according to data from a new study of the Diar portal.

According to analysts, the once popular method of financing, which allowed startups to attract tens and hundreds of millions of dollars in the absence of any product, exhausted itself against the background of fears about regulators' actions and the general dynamics of the cryptocurrency market, which did not leave retail investors with anything except for an unpleasant aftertaste.

This version is also supported by the data from the TokenData portal, which Diar leads in his research. Even with respect to the October levels, which constituted only a small fraction of what could be collected a few months ago, the November figures were 3 times lower.

Diar assumes that in the future unregulated ICOs as we have known them over the past years will no longer attract significant attention and will give way to regulated platforms of tokenized securities.
