Abstract: Methods and systems for managing and/or processing a blockchain to maintain data security for confidential and/or personal data are provided. According to certain aspects, the disclosed data security techniques may enable access sharing functionality utilizing the blockchain. For example, access sharing may be utilized to share access to audit data. The policy information may be associated with a smart contract. Accordingly, the audit data may be encrypted using a public key for the smart contract and compiled into a block of the blockchain. In response to a request to provide access to the audit data to a particular node, the private key for the smart contract may be encrypted using the public key for the particular node and compiled into a block of the blockchain.

Abstract: Methods and systems for managing and/or processing a blockchain to maintain data security for confidential and/or personal data are provided. According to certain aspects, the disclosed data security techniques may enable access sharing functionality utilizing the blockchain. For example, access sharing may be utilized to file documents, share policy information, and/or comply with an audit. The data security techniques disclosed herein also enable the use of smart contracts to transfer funds associated with payment obligations and/or other forms of blockchain based payments, comply with anti-money laundering requirements, report industry data, validate interest payments and/or maintain agent sales data. Data security may be achieved through the use of public key/private key encryption techniques.

Abstract: Methods and systems for processing a blockchain comprising a plurality of immutable sales records corresponding to sales made by agents of an entity are provided. According to certain aspects, a transaction request indicating a sale made by an agent of the entity may be received at a first node. A block including a sales record indicating the sale made by the agent may be added to a blockchain and transmitted to another node for validation. The first node may add the block to a copy of the blockchain, where the block may be identified by a hash value that references a previous block in the blockchain that includes at least one additional sales record.

Abstract: The invention relates generally to peptides which decrease the half-life of active plasminogen activator inhibitor-1. This invention further relates to methods and compositions for using peptides which decrease the half-life of active plasminogen activator inhibitor-1. Further, the invention includes methods and compositions useful in clot lysis.

Abstract: A plasminogen, which has a label incorporated into an active site thereof such that said plasminogen is enzymatically and catalytically inactive upon its conversion to plasmin, and an enzymatically and catalytically inactive plasmin with a label incorporated into an active site thereof.A method of making a labelled plasminogen which is enzymatically and catalytically inactive upon conversion to plasmin is provided along with an assay method which utilizes a labelled plasminogen.
