Toutefois, le risque principal est un problème commun à toutes les applications blockchain, Bitcoin compris. En réalité on ne sait pas encore exactement à quel point le système est sécurisé et s’il existe des failles qui pourraient être exploitées par des hackers.

Un problème potentiel autour de la blockchain tient au fait qu’à ce jour de nombreux projets ont été mis en œuvre, tous fondés sur des approches technologiques différentes. IBM, JP Morgan, Intel et d’autres entreprises viennent de lancer l’« Open Ledger Project ». Open Ledger n’utilise pas la blockchain du Bitcoin, mais met en œuvre un schéma différent plus adapté à des entreprises souhaitant restreindre l’accès au réseau blockchain.

Open Ledger Project : blockchain alternative

IBM, Cisco, Intel and some financial organisations are working on an alternative for the blockchain. The purpose is however not (yet?) to come up with an alternative cryptocurrency for bitcoin, but to build a blockchain-like technology that can bring a new level of automation and transparency to a wide range of services in the business world, including stock exchanges and other financial markets.

It has been a while that IBM has been working on blockchain-inspired software to deal with digital “Smart” contracts [1].
IBM is now going to release the code it has developed together with Digital Asset Holdings (DAH), a company that develops software for designing blockchain-technology (#Hyperledge).

The Linux Foundation oversees the Open Ledger Project.

Over the past year, IBM researchers have been developing their own version of blockchain, which the company said could be used to create secure online contracts. Mr. Krishna isn’t sure who, if anyone, would embrace a project the company so far regards as experimental
