Methods and systems are presented for providing a framework for facilitating token sharing with contract issuers based on processing of smart contract transactions. The framework provides a mechanism for allowing one or more computer nodes within a blockchain network to opt-in to a token sharing agreement with a contract issuer and a mechanism for an opted-in computer node to share tokens with the contract issuer in a decentralized manner. When a computer node has opted-in to the token sharing agreement, the computer node, by executing a smart contract, performs a set of computer procedures that is non-productive to the processing of the smart contract transaction. The execution of the set of non-productive computer procedures provides an additional amount of processing fee based on the processing of the smart contract transaction. The computer node then transfers a portion of the additional amount of processing fee to an account of the contract issuer as part of the processing of the smart contract.

Methods and systems for facilitating sharing of tokens in blockchain transactions

Techniques are disclosed relating to selection of miners/validators in a decentralized cryptographic network. In some embodiments, a request to add a transaction to a blockchain includes a cryptographic signature associated with provision of a second transfer fee, in addition to a first transfer fee, to miners/validators who meet a set of one or more criteria. Disclosed techniques may advantageously allow steering of blockchain requests to a desired subset of miners/validators.

Selection of validators in decentralized cryptographic network

There are provided systems and methods for a carbon neutral blockchain protocol for resolving carbon offsetter payments for cryptocurrency transactions. A service provider, such as an online transaction processor, may provide a green wallet and network protocol that provides carbon offsetting fees and payments to carbon offsetters in order to account for carbon emissions and usage when processing cryptocurrency transactions on a blockchain network protocol. A green wallet may be provided, which allows registration of carbon offsetters and use of green addresses to cause cryptocurrency to be processed in a green transaction. A user's digital wallet may sign an initial cryptocurrency transaction and provide the fee to the green wallet. The green wallet may then resolve the cryptocurrency transaction by further signing the transaction and transmitting the fee to a digital wallet of the carbon offsetter over another cryptocurrency processing network.
