Vitalike Buterin, creator of Ethereum, recently reported about growth of Viper's popularity among GitHub contributors.

What is Viper? 


Distributed database that is used to maintain a continuously growing list of records, called blocks

Viper is an experimental programming language that aims to provide the following features:

  • Bounds and overflow checking, both on array accesses and on arithmetic
  • Support for signed integers and decimal fixed point numbers
  • Decidability - it's possible to compute a precise upper bound on the gas consumption of any function call
  • Strong typing, including support for units (eg. timestamp, timedelta, seconds, wei, wei per second, meters per second squared)
  • Maximally small and understandable compiler code size
  • Limited support for pure functions - anything marked constant is NOT allowed to change the state

This is fairly fresh stuff, but looks interesting. As far as I understood, this language is designed to work good with a lot of numbers and maths. I believe it can be very popular.

If we will look at the "Insights" at GitHub of Viper, we can see that popularity increased meantime.

Societe Generale to Issue ETH DLT Based Bonds

Societe Generale SFH used the OFH security token, based on Ethereum's public blockchain to issue secured bonds for 100 million euros

French banking corporation Societe Generale Group issued bonds in the form of security tokens, using the public Ethereum blockchain.

On Tuesday, the company announced that its division Societe Generale SFH used the OFH token to issue secured bonds worth 100 million euros. According to the investor services of the rating agency Moody’s, Societe Generale turned out to be the “sole investor” of the financial instrument and did not involve any third-party participants in its purchase.

A bond is issued for a five-year term with a 12-month grace period. The security presented by a token gives its holder the same rights as that issued in traditional form.

Moody’s argues that the use of the blockchain can have a positive effect on the rating of a financial institution, in particular due to increased transparency and reduced likelihood of errors resulting from the difficulties and the number of intermediaries involved in the process of issuing secured bonds using traditional means.

PwC auditing company acted as a technology consultant for the project, while French law firm Gide Loyrette Nouel provided legal support.

Earlier this month, Societe Generale-owned private bank Kleinwort Hambros announced the creation of a exchange traded note, intended for investment in the blockchain industry.
