Proof-of-work challenge to transmit data to a non-authenticated gateway

A method comprising:

• transmitting, from a client to a gateway, a challenge request;
• receiving a proof-of-work challenge, responsive at least in part to the challenge request;
• solving the challenge to generate a solution;
• identifying data to be sent to a server through the gateway;
• transmitting the solution, along with the data, to the server through the gateway;
• and
• transmitting additional data to the server through the gateway for at least a threshold number of times, without the additional data being accompanied by any additional solution to any additional challenge.

A non-transitory computer-readable medium including instructions that when executed by one or more processors, cause the one or more processors to perform operations including:

• receiving, from a device, a challenge request;
• transmitting, to the device, a challenge, responsive at least in part to the challenge request, wherein the challenge is a proof-of-work challenge;
• receiving, from the device, a solution to the challenge, wherein the solution to the challenge accompanies data;
• verifying a validity of the solution to the challenge;
• and
• at least one of storing or processing the data, responsive at least in part to the solution being valid for the challenge,
• wherein the solution to the challenge is valid for one or both of storing or processing additional data from the device for at least a threshold period of time, without the additional data being accompanied by any additional solution to any additional challenge.

A system comprising:

• one or more processors;
• and
• one or more non-transitory computer-readable media storing instructions, which, when executed by the system, cause the system to perform a set of actions including:
• receiving, from a device, a challenge request;
• transmitting, to the device, a challenge, responsive at least in part to the challenge request, wherein the challenge is a proof-of-work challenge;
• receiving, from the device, a solution to the challenge, wherein the solution to the challenge accompanies data;
• verifying a validity of the solution to the challenge;
• and
• performing one or both of storing and processing the data, responsive at least in part to the solution being valid for the challenge,
• wherein the solution to the challenge is valid for one or both of storing or processing additional data from the device for at least a threshold period of time, without the additional data being accompanied by any additional solution to any additional challenge.

A method comprising:

• receiving, from a device, a challenge request;
• determining an Internet Protocol (IP) address of the device;
• determining that prior to receiving the challenge request, higher than a threshold number of additional challenge requests were received from the IP address of the device within a threshold time duration;
• selecting a higher level of challenge complexity that is higher than a lower level of challenge complexity, responsive at least in part on determining that higher than the threshold number of additional challenge requests were received from the IP address of the device within the threshold time duration;
• transmitting, to the device, a challenge that has the higher level of challenge complexity, responsive at least in part to the challenge request, wherein the challenge is a proof-of-work challenge;
• receiving, from the device, a solution to the challenge, wherein the solution to the challenge accompanies data;
• verifying a validity of the solution to the challenge;
• and
• performing one or both of storing and processing the data, responsive at least in part to the solution being valid for the challenge.
