5. The method of claim 1 , wherein the initial channel state may indicate that the first amount of digital asset was deposited into the first smart contract address and include a time stamp indicating a time at which the first amount of digital asset was deposited.

6. The method of claim 1 , wherein the non-custodial trading request includes at least one of a first customer public address, an exchange public key, a first smart contract address associated with the blockchain and the digital asset, or first smart contract instructions.

7. The method of claim 1 , wherein the first smart contract address is:

provided by the first user device;

provided by the digital asset exchange computer system; or

generated by applying an algorithm to one or more of:

a first customer public key;

an exchange public key;

a first exchange public address;

a second exchange public address; or

a first user public address.

8. A system comprising:

one or more processors; and

non-transitory computer-readable media storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:

providing, by an exchange computer system associated with a digital asset exchange, non-custodial trading information to a first user device;

receiving, by the exchange computer system from the first user device, a non-custodial trading request;

verifying, by the exchange computer system, the non-custodial trading request;

receiving, from the first user device by the exchange computer system, an initial channel state indicating a first amount of digital asset has been transferred to a first smart contract address;

confirming, by the exchange computer system, that the first smart contract address has been published on a blockchain and that the first amount of digital assets was received by the first smart contract address;

receiving, by the exchange computer system from the first user device, a first order to sell a second amount of digital asset;

receiving, by the exchange computer system from the first user device, a first transaction request digitally signed by a customer private key;

verifying, by the exchange computer system, the first order and the first transaction request;

generating, by the exchange computer system operably connected as a node of a decentralized digital asset network, transaction instructions including computer code configured to cause a transfer of payment based at least in part on the first order and the first transaction request, wherein generating the transaction instructions includes generating code configured to be utilized by other nodes of the decentralized digital asset network to facilitate the transfer of the payment;

receiving a block value generated by the decentralized digital asset network that is associated with the transaction instructions, the block value representing a block in a blockchain of the decentralized digital asset network;

determining, utilizing data received from a digital asset miner node associated with the exchange computer system, a cryptographic hash function utilized in connection with generating the block value representing the block in the blockchain;

determining, utilizing the data received from the digital asset miner node, that the cryptographic hash function is a high-speed function that is associated with increased computing power for solving new block values; and

providing an incentive to a digital asset miner in response to determining that the hash function is a high-speed function that is associated with the increased computing power.

9. The system of claim 8 , wherein verifying the non-custodial trading request comprises verifying that at least one of:

the first smart contract address is an authorized smart contract address;

a first smart contract instructions are authorized instructions;

a first user public address is an authorized public address associated with the first user device;

a first exchange public address is an authorized public address; or

a second exchange public address is an authorized public address.

10. The system of claim 8 , wherein the initial channel state may indicate that the first amount of digital asset was deposited into the first smart contract address and include a time stamp indicating a time at which the first amount of digital asset was deposited.

11. The system of claim 8 , wherein confirming that the first smart contract address has been published on the blockchain and that the first amount of digital assets was received by the first smart contract address comprises:

sending a call to the first smart contract address; and

receiving a return call confirming existence and published nature of the first smart contract address.

12. The system of claim 8 , further comprising:

receiving confirmation of deposit of the first amount of digital asset; and

depositing, in response to the confirmation, collateral into the first smart contract address.

13. The system of claim 12 , wherein the collateral is usable to impose penalty fees on the exchange computer system based at least in part on first smart contract instructions.
