In one embodiment, the decentralized and distributed IT marketplace platform is based on the blockchain technology. In one embodiment, a blockchain-based IT marketplace platform provides a decentralized supply chain for IT assets and financial services and establishes a self-regulating and trustless marketplace of connected consumers, producers, and financiers. In one embodiment, the blockchain-based IT marketplace platform enables developing, executing, financing and monetizing modern, cloud native, enterprise compute infrastructure and software applications.

In an example, an ecosystem is disclosed that may facilitate digital exchange of a digital asset stored as a computer executable file. The ecosystem may include a plurality of participant systems, wherein the plurality of participant systems may include at least one of an asset user system, an asset holder system, and an asset mining system. The ecosystem may include an asset wrapper associated with the digital asset and configured in the form of a multi-layered structure and computer-executable document. The ecosystem may include a codec configured as a computer executable file and associated with the asset wrapper, wherein the codec may be executed when an external request for the asset exchange is initiated. The ecosystem may include a blockchain device to execute a blockchain smart contract for the asset exchange, wherein the smart contract is executed against a pre-defined number of right tokens characterizing a specific cryptocurrency-value.

A system, method, apparatus, and computer software for conducting real-time cross-network counterparty-secure exchange-party-free crypto currency payments, trade, and exchange. The system includes decentralized processing computers operating together peer-to-peer in communication with multiple crypto currency blockchain networks via an internet connection. The method includes requesting a sell or a buy of a Face Value denoted as dx; publishing the request to a market network; accessing transaction data stored in multiple blockchain networks, each of the multiple blockchain networks being different from each other; quoting a value for settlement of the request denoted as dy; verifying the value as according to a predetermined protocol; issuing transactions to effect the request; and producing a trading report. By providing a generalized cryptographic security system, a real-time multiple-access exchange-party-free counterparty-secure exchange is made possible offering a huge market extremely valuable features that are not currently available to crypto currency exchange system users.

Technique introduced here relates to virtual currency related services, and more specifically, to tools for providing crypto or other digital currency (e.g. bitcoin) related services, including bitcoin DNS service, sending bitcoins over social media communication networks, a bitcoin trading platform and secure storage services for bitcoin.

The invention provides a method and corresponding system for controlling the generation of a blockchain transaction, and/or the recipient of a transaction output. It can also be used to control and record the ownership of an asset represented on the blockchain without the need for a separate registry of ownership. The ownership and transfers thereof can be handled and recorded without the need for knowledge of the parties involved or their identities. According to one embodiment, the method comprises the steps of identifying at least one transaction (Tx) on a blockchain which comprises: an unspent transaction output (UTXO) relating to a tokenised asset associated with an asset controller; and an input which spends an output from a previous transaction that is locked by a redeem script hash. For each identified transaction (Tx), an incomplete blockchain transaction is generated comprising: a first output comprising a copy of the redeem script hash; and a second output which is modifiable such that only the asset controller is able to specify a recipient for the second output. The incomplete blockchain transaction is communicated to the controller of the asset. The incomplete blockchain transaction is incomplete in that it is missing a required cryptographic signature. Thus, payment of income relating to the asset can be re-directed by the controller to a destination of their choice.

A computer-implemented includes sending a public key associated with a particular node in a cyclically-ordered set of nodes participating in a blockchain network to an initiator node; receiving, by the particular node from a node immediately previous to the particular node in the cyclically-ordered set, a first value based on public keys associated with each node from the particular node through to the initiator node; determining a locking value based on the first value and the public key associated with the particular node; and preparing using the locking value, a transaction arranged to transmit control of a resource from a source address associated with the particular node to a receiving address of a node immediately subsequent to the particular node. The control of the resource is to be transmitted responsive to satisfaction of an execution condition including supply of an unlocking value corresponding to the locking value.

A system for off-chain management, distribution and auditing of decentralized cryptocurrency is provided. The system enables an organization to mint off-chain, centrally controlled tokens for internal distribution within the organization. The system allows these tokens to be assigned an underlying value in a cryptocurrency and to be associated with distribution rules and withdrawal rules. When a token is distributed to an employee, it does not guarantee that the employee will receive the underlying value in the cryptocurrency. Instead, the token represents the employee's ability to withdraw up to the assigned underlying value in the cryptocurrency, which the organization can approve, adjust or deny. When the organization approves an employee's withdrawal of a token's underlying value, the system can manage the distribution of the token's underlying value to the employee's cryptocurrency wallet and can provide functionality for tracking, reporting and auditing such transactions.

A system and method are provided for modeling and interpreting a modeled digital asset and its evolution with respect to the rights of a plurality of parties, the method comprising: executing an await function instance no more than once using one of at least one choice defined therein for disposition of the digital asset with respect to the rights of at least one of the plurality of parties, said await function instance incorporated upon the consent of the affected parties to fulfil a configured function instance associated with the at least one choice; executing an agree function instance that requires the consent of at least one of the plurality of parties to execute; and storing the results of the executed function instances in an append-only ledger.

Systems and methods for offering and purchasing tokenized securities on a blockchain platform meeting current and future federal, state, and offering and holding entity rules and regulations. Tokenized securities purchased during or after the tokenized securities offering are tradable on a secondary market. The server computer of the tokenized securities provides an automated transfer capability for tokenized securities holders.

An exemplary transaction sharding method comprises splitting a distributed ledger into a plurality of shards; and storing a shard across the subgroup of computer nodes associated with the shard. Such a method further comprises assigning a new transaction to one of the plurality of shards, wherein assigning the new transaction comprises iteratively choosing one of the plurality of shards; in each iteration, determining a transaction-to-shard score measuring a probability that a subgroup of computing nodes associated with the chosen shard for the current iteration would be involved in a same-shard transaction for the new transaction; in each iteration, determining a latency-to-shard score by estimating a confirmation latency of the new transaction under the chosen shard for the current iteration; and selecting the new transaction to be assigned to the shard based on a combination of the transaction-to-shard score and the latency-to-shard score.
