Equity Marketplace A Blockchain Implementation

Equity Marketplace A Blockchain Implementation

About us I am Tullio Menga, ICT architect and developer. I have been working in Capital Market area during last twenty years, specifically in the field of high performance infrastructures. I am currently collaborating with ATS, Milano (IT), having its core business in Capital Market. ATS is Innovation Partner of UCL. We are currently exploring use cases of blockchain technology in OTC derivatives, non-listed equities and several other areas.

Blockchain in brief SECURITY NEAR-REAL-TIME immutable, non-tamperable transactions cryptographic encryption consensus REDUDANCY decentralisation data replication on nodes no single point of failure IMMUTABLE DISTRIBUTED TRANSACTION LEDGER transactions are etched to the ledger as they are processed no need for end-of-day batch processes PROCESS OPTIMIZATION smart contracts to define complex business logics complex transactions execute atomically

Blockchain in Capital Market t+0 t+0 t+y t+x TODAY Several back-offices use different technologies and interact at different times, leading to very complex, slow and non-atomic transactions, possible human errors and slow reaction to failures. FUTURE Distributed ledgers handle complex transactions atomically, in nearreal-time, and share updates at transaction time, leading to safer and faster processes, less human errors and quicker reaction to failures. FINANCIAL INSTITUTIONS Intracompany settlement Loan settlement Trade settlement Trading Collateral management Derivatives clearing Derivatives agreements Cross-border payments REGULATORS Trade reporting Compliance reporting Risk visualisation Transparency regulation Anti-money-laundring

OTC Derivatives and Equities OTC Derivative Trading NON-listed EQUITY Trading Market Engine (book, matching) X X Post-trade settlement X X Contract issuing (master agreement) Contract maturity settlement X X Shares management X X Collateral management X X Instrument pricing Margination management X X Trade-offs Requires more features and more complex More problematic normative aspects (may involve CCP obligations) Requires less features Easier normative aspects (no CCP obligations) focus of this presentation

Why a blockchain? LEGAL PROCESS TECHNICAL IMMUTABLE TRANSACTION LEDGER MANY PROCESSES IMPLEMENTED ON SAME ASSETS TECHNICAL BENEFITS Ownership Provides a reliable register of asset property exchanges Compliance Provides access to auditable data, verified and hard to tamper No Central Counterparty Distributed ledger eliminates need of third-parties such as a CCP, and risk from single point of failure 1 transaction many assets Transactions involving many assets, such as ollaterals can be implemented atomically. 1 asset many transactions Different transactions involving the same asset, such as trading equity shares and using them for collateral allocation, can be implemented atomically. Several participants perform better Consensus is more reliable when the number of particdipants increase, without significantly loosing performance. Near-real-time transactions Can make settlement faster, reducing the need of separate batch accounting processes.

Equity Trading Processes CASH LEDGER asset: currency transactions: amount transfers actor: financial institutions SECURITY LEDGER asset: equity shares transactions: ownership exchanges actor: custodians COLLATERAL LEDGER asset: collaterals transactions: collateral allocations actor: central counterparties blockchain pegging

Equity Trading Ledger EQUITY TRADING LEDGER assets: currency and equity shares transactions: trades and collateral allocations smart contracts: custodian and central counterparty business logics actors: financial institutions only

OTC Derivatives and Equities Private Permissioned Public Permissionless Participants Controlled, trusted. Free, trustless. Potential market liquidity Controlled by participants. All the circulating crypto-currency. Performance (current) Higher (1 block <3s). Low (1 block in minutes). Security Same as any common private network. Relies on anonymous accounts, must be analysed in details. Ledger permissioning Embedded, rules defined by stakeholders. Harder to control (participants can be anonymous). Regulator / normative implications Rules can be defined to meet regulatory compliance. Regulatory institutions can be participants themselves Harder to meet regulator compliance requirements (it is a natively cross-border platform). Trade-offs greater performance finer permissioning control more normative-oriented (CSDs plays a role) more normative oriented consensus basis must be built greater potential penetration greater consensus basis slow performance hardly controlled permissioning harder to meet compliance rules (no CSDs) public code, easier hacker attacks Our choice

C2014 ATS Today

Our Model who does what are the user participants of the platform do trading transactions do collateral allocation transactions manage updating of balances on real-world bank accounts Financial Institutions are the owner participants of the platform are responsible for normative compliance read security ownership exchanges manage updating of their security accounts CSD(s) Bank Accounts Interested in information from the ledger In practice, may receive red information from participants ideally, can be participants with read-only access to the ledger Regulator implement the market engine business logic of CSDs, atomically to trading transactions business logic of CCPs, atomically to collateral allocation transactions Smart Contracts Security Accounts
