STACS BLOCKCHAIN MODEL
How do Financial Institutions fit into the STACS Ecosystem with Blockchain?
STACS Permissioned-Global Networks
Experience synergies in shared networks while preserving proprietary data
Native STACS Scenarios
- An individual Bank A (ie. Native STACS 1 and 2).
- A group of separate Banks A, B and C (ie. Native STACS 3) together
- Read-veto access rights can be configured for the Regulator (ie. Native STACS 4), in a digital ecosystem with an Exchange, Central Securities Depository and supporting institutions
- Permitted access can be given to other participants joining the ecosystem (ie. Native STACS 3 and 4).
Global STACS Scenarios
Market participants can experience synergies in shared networks while preserving proprietary data. Moreover, where needed, a permissioned blockchain (ie. a standalone Native STACS) can be plugged to other permissioned blockchains.

STACS Competitive Advantages
Designed for Finance
- Governance Policy
- Production Ready
- Transaction Finality, Strict Ordering
- Digital Fingerprint
- Integration Focused
- High Availability & Disaster Recovery
- Each node has programmable business logic, based on Java, to ensure adaptable access controls for changing enterprise needs – including privacy, eligibility, permissions, digital identity, domains and other business parameters.
- Java was chosen as a stable, established, secure programming language with a global developer base.
- Ever-changing business requirements are supported via Settlity SMT API connectivity layers and SDKs
- STACS offers speed-to-market by deploying a production-ready underlying ledger, connected together with business-ready supporting enterprise applications.
- Rather than relying on third-party developers to build costly applications, STACS can provide the market-ready full range of applications.
- STACS supports high Transactions Per Second (TPS) of 4,500, as demonstrated in recent stress-tests done with Dell – read the technical report here
- Low cost to scale as every single node maintains the same global ledger state
- Supports both Omnibus and Account-subaccount structure with multiple layers to support B2B, B2C.
- STACS achieves transaction finality with our unique consensus algorithm based on a combination of RAFT and PBFT.
- STACS has a strict lineage order with regards to transaction executions
- STACS provides a single source of truth as all transactions (including configuration and administrative) are on the same single ledger
- The on-chain Digital Fingerprint profile enables the on-chain enforcement of transactions and conditions through smart contracts.
- For instance, the asset’s transferability and trade eligibility will be based on the investor’s suitability or KYC/AML standards, while being in compliance with regulations.
- Staying within data privacy laws, personal information will not be published on-chain.
- Privacy features are available, where information can be encrypted. Institutions can also form “Private Networks”, where only participants can receive these transactions. Transaction integrity and balance checks are maintained for all Transactions
STACS co-develops use cases with financial institutions to ensure they are meaningful for the industry.
- Integrated with existing financial platforms and supporting standards
- Interoperable with other blockchain ledgers – Solidity smart contracts supported, Cross-chain functionality supported with Hyperledger Fabric and Quorum today.
- Integration of STACS Ecosystems – Native STACS ecosystems are integrated with each other through Global STACS layer
A participating organisation in the network can host multiple nodes under one domain.
- Should a node fail in a High Availability (HA) scenario, other nodes will take over. Consensus integrity is maintained with one vote per domain.
- Node Failover handles Disaster Recovery (DR) which also allows the entire network to maintain high uptime service levels
- Simple and cheap to recover, as every single node is on the same ledger state including all configurations.
