  • IT information technology
  • the Digital Asset Modeling Language (DAMLTM) is an expressive language enabling financial institutions to model and execute agreements with certainty and finality.
  • the Global Synchronization Log based on Distributed Ledger Technology (DLT) is a shared, replicated ledger, such as but not limited to a blockchain, with a synchronizing mechanism known as a "consensus algorithm”.
  • a Contract Authorization and Distribution Framework (CADF) supports or includes a service to selectively disclose contracts to parties involved and collect their authorizations for decisions.
  • the presently disclosed Digital Asset Platform supports roles with different abilities to enter into and/or review agreements, or technically support the security of the platform.
  • Unique design decisions while configuring DAMLTM, DLT Log, and/or CADF provide powerful tools to streamline and execute contractual workflows between and within financial institutions.
  • DAMLTM code models an agreement between parties as a model typically eventually referencing further DAMLTM models, which each evolve through a decision by a party into a new model.
  • the new model might involve other parties to or into the contract, might offer new decision choices, or might even be the same as the previous model.
  • Unique properties of the DAMLTM language particularly suited for such purposes include: 1 ) A DAML model enumerates all possible current choices of the parties and their respective consequences. 2) A decision evolves a DAML model into a new DAML model in finite steps after which the new DAML model awaits new decisions to evolve further.
  • a DAML model can be analyzed, to deduce: a) Current parties and their available choices; and b) The set of parties who would become involved in the new contract if a current party would decide for any of its respective current choices. 4) DAML allows for extracting fractions of the model such that those fractions are also valid DAML models on their own, but potentially with a lesser number of involved parties.
  • DAML is human readable and editable, it can be converted into and from a well-defined and unique technical representation called an Abstract Syntax Tree (AST), as shown in Figure 2.
  • AST Abstract Syntax Tree
  • DAML allows for Operators that might combine Stubs or further Operators.
  • An Operator might represent a decision option and its sub-tree might define the effect of the decision.
  • a Stub might be replaced with a model, again represented as an AST, in consequence of a decision.
  • DLT Distributed Ledger Technology
  • DLT presents an alternative to third-party and bilateral bookkeeping. Its primary advantages lie in scalability if compared with bilateral bookkeeping, and lie in attack resilience if compared to third-party bookkeeping.
  • Distributed Ledger Technology introduces multilateral bookkeeping whereby members of the network cooperate to create a reliable shared infrastructure that decides on the order of agreements. Once the order of agreements is definite, contradicting agreements may be resolved by considering only the earlier agreement valid.
  • the DLT Global Synchronization Log is an append-only log of evidence for agreement evolutions. The DLT Log data structure features sophisticated integrity proofs based on digital signatures and cryptographic hashes.
  • DLT Log network can prove to themselves through execution of a consensus algorithm that their copy of the log matches those of the majority of network participants.
  • a benefit of DLT for contractual parties is that if the parties decide that the DLT Log shall include all contracts, it can identify the complete set of current contracts while automatically excluding alternatives.
  • the DLT Log When representing the complete set of current contracts, the DLT Log also acts as a publication channel to announce new contracts to the parties involved. Notification of involved parties is required for the validity of an agreement.
  • the presently disclosed Digital Asset Platform stores notification tokens into the evidence of the new model. Involved parties may monitor for their tokens. To protect privacy of involved parties, the notification token is calculated such that it is known to be linked to the party only by the writer of the log and the involved party.
  • the notification token is a function of a shared secret between the log writer and the notified party. Derivation of shared secrets is made possible by prior announcement of the identities of the log writer and the involved parties on the log. Identities are tied to public keys for which the private key is kept secret by the actor behind the announced identity. The log supports announcement and revocation of identities for regular key rolling or emergency withdrawal after a security breach affecting the party.
  • a Contract Authorization and Distribution Framework (CADF) are used for decisions that require proper authorization by the party who makes a choice.
  • the platform collects digital signatures on business intent formalized using DAML derived ASTs into evidence authorization. Since the DAML might not be authored by the authorizer, it needs to be delivered on demand by the author's network node. Delivery of the AST for signature might be denied if the requestor is not entitled to see the contract, or replied with a partially blinded AST, just sufficient to support the decision process of the authorizer.
  • the platform uses a Merklized Abstract Syntax Tree (MAST) for partial blinding of an AST. Parts of an AST are substituted with the Merkle Hash of their respective sub-tree to create a MAST. Merkle Hashes do not reveal anything about the information blinded. Merkle Hashes are computed such that the digital signature on the complete AST or on any of its derived MAST is verifiable with knowledge of the AST or any of its derived MAST. As a result, parties will hold incomplete sets of copies of models just as they are entitled to see or are required to authorize. Their model storage resembles multilateral bookkeeping, but formalized and properly authorized.
  • MAST Merklized Abstract Syntax Tree
  • the new agreement will be evidenced on the DLT Log.
  • the evidence does not disclose anything about the model's content, but is a fingerprint compiled such that all involved parties are able to prove that the evidence is for a particular agreement.
  • the multilateral model store filtered by evidence on the DLT Log completely and reliably defines the current set of agreements for all parties involved.
  • the various network nodes connected to the shared infrastructure may have different roles.
  • a node may fulfill several roles.
  • a network node that records evidence into the append-only log is a ledger writer. Although technically not necessary, it will most likely also guarantee the contradiction-less recording of evidence and, as a consequence, have full visibility into agreements it records, for which it will have full records in its CADF.
  • the role of the ledger writer might be shared by several nodes, such that a ledger write requires joint authorization by them in desired scenarios.
  • Another role is that of a "ledger reader”. This is a network node that acts in behalf of parties that might be involved in some agreements or for supervising authorities. The ledger reader will watch out for notifications for its served parties on the DLT Log, and aggregate a partial database of agreements through its CADF.
  • Auditor Yet another role is that of an "auditor".
  • the purpose of an Auditor is to keep a check on the ledger writer by proving that agreement evolutions are properly executed and authorized and that involved parties were notified and no contradicting agreements were recorded. Similar to the ledger writer, an Auditor will have some visibility into agreements, but in addition it will also have knowledge of shared secrets for many parties. A breach of protocol by the Ledger Writer would be flagged by the Auditor and handled outside of the described shared infrastructure. Since the Auditor's task is the execution of a checking algorithm that needs no human discretion or oversight, the Auditor may be an autonomously executed algorithm running within a secure computing environment. Communication with the secure environment may be encrypted, and it may be configured so no data may leave the secure environment except for raising a flag on any failed rule validation the Auditor observes.
  • All code, data structures and the like discussed above can be stored in non- transient computer readable storage media.
  • Functional steps described herein can be accomplished by computer code executed on a processor.
  • the various data manipulations described above can be accomplished on stored data structures to create transformed data structures that are processed by a computer processor in a different manner.
  • the various functions of the embodiments allow a computing system to operate in a new manner to accomplish transactions and provide new advantages.
  • the various flowchart steps can be accomplished by software modules executed on a computer processor.
  • Blocks illustrated in the figures can represent data structures, such as databases storing records, which are manipulated in the described manner to allow a computing system to operate on the data and transform the data.
