In use, a centralized blockchain marketplace is accessed. Additionally, one or more blockchain offers are selected via the centralized blockchain marketplace, and one or more nodes are selected to process the one or more blockchain offers. Further, the one or more nodes are managed based on progress metrics associated with each of the one or more blockchain offers. ## Claims ### Claim 1 A device, comprising: a non-transitory memory storing instructions; and one or more processors in communication with the non-transitory memory, wherein the one or more processors execute the instructions to: access a centralized blockchain marketplace; select one or more blockchain offers via the centralized blockchain marketplace; select one or more nodes to process the one or more blockchain offers; and manage the one or more nodes based on progress metrics associated with each of the one or more blockchain offers. ### Claim 2 (depends on 1) The device of claim 1, wherein the one or more nodes includes users, miners, hardware systems, or an application specific integrated circuit (ASIC). ### Claim 3 (depends on 1) The device of claim 1, wherein the one or more blockchain offers originate from one of a provider or a developer. ### Claim 4 (depends on 1) The device of claim 1, wherein each of the one or more nodes are associated with a commitment level, such that a pre-allocated amount of available resources is designated for each of the one or more nodes. ### Claim 5 (depends on 4) The device of claim 4, wherein the pre-allocated amount of available resources includes hashing power. ### Claim 6 (depends on 1) The device of claim 1, wherein the centralized blockchain marketplace receives each of the one or more blockchain offers as a mining package. ### Claim 7 (depends on 6) The device of claim 6, wherein the centralized blockchain marketplace ensures that the mining package satisfies a compliance associated with the centralized blockchain marketplace. ### Claim 8 (depends on 1) The device of claim 1, wherein managing the one or more nodes includes allocating hashing power associated with each of the one or more nodes. ### Claim 9 (depends on 8) The device of claim 8, wherein the hashing power is re-allocated at a later time period. ### Claim 10 (depends on 1) The device of claim 1, wherein managing the one or more nodes includes defining a threshold for each of the one or more blockchain offers. ### Claim 11 (depends on 10) The device of claim 10, wherein the threshold is defined by specifying a hashing command hashing power for each of the one or more blockchain offers. ### Claim 12 (depends on 11) The device of claim 11, wherein the centralized blockchain marketplace automatically proposes automatic reallocation of the hashing commands. ### Claim 13 (depends on 12) The device of claim 12, wherein implementing the automatic reallocation is dependent on receiving an approval from a user. ### Claim 14 (depends on 1) The device of claim 1, wherein the progress metrics include at least one of a hashing power associated with each of the one or more nodes, an electricity consumption rate associated with each of the one or more nodes, a processor load associated with each of the one or more nodes, a time to completion associated with each of the one or more nodes, a reward level associated with each of the one or more nodes, a difficulty of the blockchain offer processed by each of the one or more nodes, a collaboration of more than one node of the one or more nodes, a time spent on the one or more blockchain offers associated with each of the one or more nodes, an up-time associated with each of the one or more nodes, a connection rate associated with each of the one or more nodes, or a price per hashing power associated with each of the one or more nodes. ### Claim 15 (depends on 1) The device of claim 1, wherein the one or more processors execute the instructions to display an indication of a completion of one of the one or more blockchain offers. ### Claim 16 (depends on 15) The device of claim 15, wherein, in response to the completion, a payment is processed and delivered to an owner of the respective one or more nodes. ### Claim 17 (depends on 1) The device of claim 1, wherein the centralized blockchain marketplace is used to receive a solicitation or bid for one of the one or more blockchain offers. ### Claim 18 (depends on 1) The device of claim 1, wherein two nodes of the one or more nodes are selected to process the selected one or more blockchain offers. ### Claim 19 A computer program product comprising computer executable instructions stored on a non-transitory computer readable medium that when executed by a processor instruct the processor to: access a centralized blockchain marketplace; select one or more blockchain offers via the centralized blockchain marketplace; select one or more nodes to process the one or more blockchain offers; and manage the one or more nodes based on progress metrics associated with each of the one or more blockchain offers. ### Claim 20 A computer-implemented method, comprising: accessing a centralized blockchain marketplace; selecting one or more blockchain offers via the centralized blockchain marketplace; selecting one or more nodes to process the one or more blockchain offers; and managing the one or more nodes based on progress metrics associated with each of the one or more blockchain offers.
