Methods, systems, and devices for data management are described. A client application may receive an input to perform an action at a decentralized exchange. The client application may broadcast, via a blockchain network, messages configured to cause smart contracts on the blockchain network called by the decentralized exchange to verify whether a blockchain address associated with the input is authorized to perform the action at the decentralized exchange. In some examples, verifying may include checking a status managed by an entity different from the decentralized exchange. The smart contracts may perform the action after verifying that the blockchain address is authorized to perform the action, or the smart contracts may fail to perform the action after failing to verify that the blockchain address is authorized to perform the action.

Computing systems are configured to provide a hierarchical organization of blockchain operations, efficiently storing recursive hashes that allow quick verification of received data and data state. Received data from authorized users in associated and stored by representation at a corresponding position in the hierarchy. The computer hashes and tokenizes received data with the hash and stores the same. Each token created is then separately hashed with time and creator into a listing of all such tokens within an object. Such re-hashing is reiterated up each hierarchy level and stored in the containing object. The lists of all hashes at each level can be used to verify a state or individual document that will be reflected in the stored listings is accurate or currently true. Additionally, user actions and histories, as well as state progression and history, can be queried and reported easily with the lists.

A computer system and method for storage and retrieval of multiple encrypted data. The system and method allow a user to first encryption data with a first key only held by the user such that the user solely possesses one of the necessary keys for later decryption of the stored and encrypted data. The firstly encrypted data is then doubly encrypted and stores the data in such a secure manner that the data can be stored on a public blockchain architecture, if desired. Full decryption of the original user data can only be performed with access to the user's initial key.

System and methods for physical authentication using blockchain technologies. A user list is encoded via hashes of respective wallet addresses to construct a Merkle Tree. The Merkle Root of the constructed Merkle Tree is recorded on the blockchain. The Merkle Tree and the Merkle Root are updated each time a user is added to the organization. A user is authenticated by submitting a message to the client, which creates a Merkle Proof and sends it to the blockchain for authentication. The process can be facilitated by a mobile application that generates a Quick Response (QR) code representing the user's wallet address.

Systems and computer-implemented methods for freezing or unfreezing digital assets on a blockchain. A freeze administration service may send a signed freeze request to mining nodes, which maintain two blacklists of digital asset identifiers: a pending blacklist and a consensus blacklist. The digital asset identifiers may be transaction outpoints in some cases. If accepted by the mining node, the transaction outpoints in the freeze request are added to the pending blacklist, which causes rejection of any transactions using those outpoints, but does not cause rejection of any new blocks that include transactions using those outpoints. If a consensus threshold of acceptances is reached based on hash power, the request becomes an order and the outpoints are added to the consensus blacklist, which causes rejection of any transaction or block containing a transaction using those outpoints.

Systems, methods, and computer-readable media disclosed herein relate to reducing computation and computing resources for certain blockchain related transactions. Specifically, software algorithms and architecture allow some transactions to avoid the need for recordation on a blockchain, which can be computationally expensive both for a requesting device and for various nodes on the blockchain. Thus, a computer system may receive indications of incoming transactions transferring digital assets to particular user accounts, and in response to requests from user accounts, the computer system facilitates one or more internal transactions between those accounts. In response to a request from a particular internal user account, the computer system may perform an outgoing transaction transferring one or more digital assets to an external user account from one or more internal user accounts. The incoming transactions and outgoing transaction are recorded on the blockchain, but the internal transactions are recorded on an internal ledger rather than the blockchain, saving computational power and improving computer operations.
