Challenges for investment banks 2017 (Part 10): Using Distributed Ledger Technology

For blockchain-based DLT to gain acceptance, banks will need to ensure that their blockchain-enabled solutions comply with all current regulatory mandates.

At the heart of the long-term opportunity for blockchain is the ability for banks to move operational, risk, and finance systems to shared data platforms using blockchain-based distributed ledger technology (DLT) and decommission large portions of their current process and data infrastructure. It will take time and multiple iterations of the platforms to get to that end-state but the potential for material cost and efficiency gains are what is driving the industry's focus and investment.

Blockchain technology could reduce infrastructure costs for eight of the world's 10 largest investment banks by an average of 30 percent, translating to $8 billion to $12 billion in annual cost savings for those banks, according to a new report by Accenture and McLagan, a business unit of Aon plc.

But to be clear-blockchain is not a panacea. It will improve some processes, but not all.  And it is still early days.

There are questions around a broader adoption that need to be addressed from a regulatory angle including: How will standards be created and by whom? As the technology matures over time, how will new standards be changed and adopted to keep pace with the technology? How will governance models be structured? How will expectations around these functions shift in an environment where group consensus is key to success?

Uncertainty remains around the regulatory response to blockchain, but it is likely that regulators will respond to banks and industry blockchain initiatives rather than provide best practice guidance, at least in the near term. For blockchain-based DLT to gain acceptance, banks  will need to ensure that their blockchain-enabled solutions comply with all current regulatory mandates.

 Immutability: Friend or Foe?

One of the most notable features of blockchain is immutability. Yet, this fixed and indelible structure may limit blockchain's ability to meet certain regulations. The fact that data can be entered into but not removed from the ledger has profound positive implications for data lineage, auditing and tracking.

However, to mitigate risk enterprises must have the ability to address fraud, comply with regulatory mandates, and correct errors and omissions, all while maintaining an immutable audit trail-especially in permissioned systems. This requires  a careful balance between preserving the benefits of blockchain and providing a safety valve for authorized administrators.

The Accenture-Ateniese redaction capability offers a way to "edit" standard blockchains, while maintaining the fundamental value of the technology's immutability. Developed in collaboration
