A computer-implemented method for processing a resource of a block chain, comprising: issuing stake certificates in a block chain based on a set stake certificate issuing mechanism, allocating the stake certificates to stake accounts according to a stake proportion, and storing operation data of the issuing and allocating the stake certificates into the block chain, the stake accounts referring to block chain accounts; issuing circulation resources in the block chain based on a set circulation resource issuing mechanism, allocating the circulation resources to the block chain accounts according to a circulation resource allocation strategy, and storing operations of the issuing and allocating the circulation resources into the block chain, wherein the circulation resource is a digital currency, comprising: acquiring a circulation resource update vote transaction request initiated by a stake account; performing the circulation resource update vote transaction request to request other stake accounts to vote on an update operation for the circulation resource; and performing the update operation on the circulation resource according to a voting result, and storing transaction data of the circulation resource update vote transaction request into the block chain, wherein the update operation comprises additional issuance and an allocation strategy of the circulation resource, and the corresponding update operation is performed on the circulation resource, if a set proportion of stake accounts vote for the update operation; and ascertaining (S103, S209), during operation of the block chain, a block-producing node according to a delegated proof of stake consensus algorithm, by using the stake certificate of each stake account as a consensus certificate. issuing stake certificates in a block chain based on a set stake certificate issuing mechanism, allocating the stake certificates to stake accounts according to a stake proportion, and storing operation data of the issuing and allocating the stake certificates into the block chain, the stake accounts referring to block chain accounts; issuing circulation resources in the block chain based on a set circulation resource issuing mechanism, allocating the circulation resources to the block chain accounts according to a circulation resource allocation strategy, and storing operations of the issuing and allocating the circulation resources into the block chain, wherein the circulation resource is a digital currency, comprising: acquiring a circulation resource update vote transaction request initiated by a stake account; performing the circulation resource update vote transaction request to request other stake accounts to vote on an update operation for the circulation resource; and performing the update operation on the circulation resource according to a voting result, and storing transaction data of the circulation resource update vote transaction request into the block chain, wherein the update operation comprises additional issuance and an allocation strategy of the circulation resource, and the corresponding update operation is performed on the circulation resource, if a set proportion of stake accounts vote for the update operation; and acquiring a circulation resource update vote transaction request initiated by a stake account; performing the circulation resource update vote transaction request to request other stake accounts to vote on an update operation for the circulation resource; and performing the update operation on the circulation resource according to a voting result, and storing transaction data of the circulation resource update vote transaction request into the block chain, wherein the update operation comprises additional issuance and an allocation strategy of the circulation resource, and the corresponding update operation is performed on the circulation resource, if a set proportion of stake accounts vote for the update operation; and ascertaining (S103, S209), during operation of the block chain, a block-producing node according to a delegated proof of stake consensus algorithm, by using the stake certificate of each stake account as a consensus certificate.
