All other embodiments that can be derived by a person skilled in the art from one or more of the embodiments described herein without making any inventive step shall fall within the scope of protection of this document.

One or more embodiments of the present specification provide a method, an apparatus, and a device for delivering an email based on a blockchain, which automatically detect current time based on an intelligent contract deployed in the blockchain, and automatically deliver the email when the delivery time of the email to be delivered is reached without manual intervention, thereby greatly improving the maintenance efficiency of the email and ensuring timely and effective delivery of the email; meanwhile, the authenticity of the electronic mails saved in the block chain and the confidentiality of the non-open mails are ensured based on the non-tampering property of the data of the block chain; moreover, based on the decentralized characteristic of the block chain, the delivery of the E-mail is independent of a certain block chain node, and a plurality of block chain link points provide delivery service together, so that the problem that the E-mail cannot be sent due to the fact that the delivery service is not provided by a certain block chain link point is effectively solved.

Fig. 1 is a schematic view of an application scenario of a block chain based mail delivery method according to one or more embodiments of the present specification, as shown in fig. 1, the scenario includes: the method comprises the steps that a sender terminal device, a first block chain node of an access block chain and a receiver terminal device are connected; the terminal equipment of the sender and the terminal equipment of the receiver can be a mobile phone, a tablet computer, a desktop computer, a portable notebook computer and the like, and the terminal equipment of the sender and the terminal equipment of the receiver are in communication connection with the first block link point through a wireless network.

Specifically, as shown in fig. 2, the terminal device of the sender responds to the delivery request of the sender, and obtains the letter element and the delivery time set by the sender, wherein the letter element includes the destination address of the recipient; and generating the E-mail according to the acquired mail element, and sending a mail delivery request to the first block chain node according to the E-mail and the delivery time. The first block chain node receives a mail delivery request sent by the terminal equipment of the sender, and stores the electronic mail and delivery time association included in the mail delivery request into the block chain; detecting the current time based on the intelligent contract, and determining whether to deliver the electronic mails stored in the block chain according to the current time; the intelligent contract is set to deliver the E-mail when the delivery time of the E-mail is reached so as to deliver the E-mail to the addressee of the addressee. The addressee's terminal device presents the received electronic mail in response to the addressee's mail look-up request. Therefore, on the basis of ensuring the authenticity of the e-mails, the maintenance efficiency of the e-mails is improved, and the timely and effective delivery of the e-mails is ensured.

Based on the architecture of the application scenario, one or more embodiments of the present specification provide an email delivery method based on a block chain. Fig. 3 is a flowchart illustrating a block chain-based email delivery method according to one or more embodiments of the present disclosure, where the method in fig. 3 can be performed by a first block chain link point in fig. 1, as shown in fig. 3, and the method includes the following steps:

step S102, receiving a mail delivery request sent by a terminal device of a sender, wherein the mail delivery request comprises an electronic mail to be delivered and the delivery time of the electronic mail;

step S104, storing the association between the E-mail and the delivery time into a block chain;

step S106, detecting the current time based on the intelligent contract, and determining whether to deliver the electronic mails stored in the block chain according to the current time; wherein the intelligent contract is set to deliver the e-mail when the delivery time of the e-mail is reached.

In one or more embodiments of the description, based on an intelligent contract deployed in a block chain, the current time is automatically detected, and delivery processing is automatically performed when the delivery time of the electronic mail to be delivered is reached without manual participation, so that the maintenance efficiency of the electronic mail is greatly improved, and the timely and effective delivery of the electronic mail is ensured; meanwhile, the authenticity of the electronic mail saved in the block chain and the confidentiality of the non-public mail are ensured based on the non-tampering property of the data of the block chain.

In order to ensure that the delivery time of each e-mail is effectively monitored in consideration of that the delivery time of different e-mails is different, in one or more embodiments of the present specification, a corresponding intelligent contract is deployed for each e-mail; specifically, as shown in fig. 4, before step S106, the method further includes:

step S105, a first intelligent contract corresponding to the electronic mail is deployed according to the delivery time, wherein the first intelligent contract is set to deliver the corresponding electronic mail when the delivery time of the corresponding electronic mail is reached;

correspondingly, as shown in fig. 4, in step S106, detecting the current time based on the smart contract includes: a current time is detected based on the first smart contract.

By deploying the first intelligent contracts in one-to-one correspondence with the electronic mails, targeted time detection and delivery processing can be performed according to different electronic mails. In order to clarify the correspondence between the first intelligent contract and the electronic mails and ensure that the electronic mails can be accurately delivered, as shown in fig. 5, before step S104, the method further includes:

step S103, determining a letter identifier of the electronic letter;

specifically, extracting partial fields of the e-mail, calculating a hash value of the extracted partial fields, or calculating a hash value of the whole e-mail, and determining the calculated hash value as a mail identifier of the e-mail; or, dynamically generating the letter identification of the electronic letter based on a dynamic generation mechanism of the letter identification, wherein the dynamic generation mechanism of the letter identification can ensure that the generated letter identifications are different from each other.

Corresponding to step S103, as shown in fig. 5, step S104 includes: storing the e-mail, the delivery time and the mail identification association into a block chain;

specifically, the e-mail, the delivery time of the e-mail and the mail identifier of the e-mail are recorded in a correlated manner, the recorded information is used as the mail delivery information corresponding to the mail delivery request, and the mail delivery information is stored in the block chain.

Further, corresponding to step S103, as shown in fig. 5, step S105 includes: and deploying a first intelligent contract corresponding to the electronic mail according to the delivery time and the mail identification.

Therefore, the first intelligent contract is deployed according to the delivery time of the electronic mail and the mail identification, so that the delivery time of the electronic mail corresponding to the mail identification is automatically detected based on the first intelligent contract without manual maintenance, the maintenance cost is reduced, the management efficiency of the electronic mail is improved, and the electronic mail can be delivered in time; meanwhile, by storing the letter delivery information into the block chain, the non-tamper property of the electronic letters and the confidentiality of the non-open letters are ensured; based on the letter identification in the first intelligent contract and the letter identification in the letter delivery information, the corresponding electronic letter can be quickly and accurately acquired when the electronic letter is delivered, so that the delivery accuracy of the electronic letter is ensured; specifically, the step S106 of delivering the e-mail stored in the block chain includes:

s106-2, acquiring the electronic mail stored in association in the block chain based on the mail identification contained in the intelligent contract;

s106-4, acquiring a receiving address of a receiver from the acquired e-mail;

and step S106-6, delivering the acquired e-mail to the acquired destination address.

Specifically, based on the letter identification contained in the intelligent contract, corresponding letter delivery information is obtained in the block chain, the electronic letter and the receiving address of the receiver of the electronic letter are obtained from the obtained letter delivery information, and the obtained electronic letter is delivered to the obtained receiving address.

In the method, the current time is detected through the first intelligent contract corresponding to the electronic mail deployment to be delivered, and when the delivery time of the corresponding electronic mail is reached, the corresponding electronic mail is delivered, so that the electronic mail is delivered quickly and accurately.

Further, in consideration of the strong operation capability of the blockchain node and in order to improve the utilization rate of resources, in one or more embodiments of the present specification, only one intelligent contract may be deployed, and for convenience of differentiation, the intelligent contract is referred to as a second intelligent contract, so as to detect, by the second intelligent contract, delivery times of all electronic mails to be delivered, and perform delivery processing. Further, since the delivery time of the e-mail is usually one year, five years, ten years, or even longer in the future due to the slow delivery, in order to improve the efficiency of the e-mail delivery management, in one or more embodiments of the present disclosure, as shown in fig. 6, step S104 includes:

step S104-2, calling a second intelligent contract, and determining a time period corresponding to the electronic mail according to a preset time period division rule;

the preset time period division rule can be set in practical application according to needs, for example, taking the year as a unit, the delivery time of the e-mail is 2021 year, 6 month and 1 day, and the time period corresponding to the e-mail is determined to be 2021 year, 1 month and 1 day to 2021 year, 12 month and 31 days.

Step S104-4, storing the E-mail, the time period corresponding to the E-mail and the delivery time association into the block chain.

Specifically, the e-mail, the time period and the delivery time corresponding to the e-mail are recorded in a correlation mode, the recorded information is used as the mail delivery information corresponding to the mail delivery request, and the mail delivery information is stored in the block chain.

By determining the time period corresponding to the e-mail, in the detection process of the delivery time, the delivery time of the e-mail corresponding to the current time period can be detected only, and the delivery time of all the e-mails stored in the block chain does not need to be detected; specifically, as shown in fig. 6, in step S106, detecting the current time based on the intelligent contract, and determining whether to perform delivery processing on the e-mail stored in the blockchain according to the current time includes:

step S106-8, detecting the current time based on a second intelligent contract, wherein the second intelligent contract is set to deliver at least one electronic mail when the delivery time of the at least one electronic mail is reached;

step S106-10, determining a target time period corresponding to the current time;

and S106-12, determining whether to carry out delivery processing on the electronic mail corresponding to the target time period according to the current time and the delivery time stored in the block chain in association with the target time period.

Specifically, target letter delivery information containing a target time period is obtained from letter delivery information stored in a block chain; comparing delivery time contained in the target letter delivery information with current time, and if the delivery time is consistent with the current time, determining to deliver electronic letters contained in the target letter delivery information; if not, the target letter delivery information contains the E-mail, and the E-mail is determined not to be delivered.

Further, the delivery processing of the electronic mail contained in the target mail delivery information comprises: and acquiring the E-mail from the target mail delivery information, acquiring the receiving address of the addressee from the acquired E-mail, and delivering the acquired E-mail to the acquired receiving address.

For example, the current time is detected to be 2019, month 1 and year 1 based on a second intelligent contract by taking the year as a unit, and the target time period is determined to be 2019, month 1 and day to 2019, month 12 and day 31; acquiring target letter delivery information comprising target time periods from 1 month and 1 day in 2019 to 12 months and 31 days in 2019 from a block chain, and if the delivery time contained in one target letter delivery information is 2019, 12 months and 25 days and is inconsistent with the current time, determining that the delivery processing is not carried out on the e-mail contained in the target letter delivery information; if the delivery time contained in the other target letter delivery information is 2019, 9, 1 and is consistent with the current time, the delivery processing of the e-mail contained in the target letter delivery information is determined, the e-mail is obtained from the target letter delivery information, the destination address of the addressee is read from the obtained e-mail, and the obtained e-mail is delivered to the read destination address.

Therefore, by determining the target time period to which the current time belongs, whether the electronic mail corresponding to the target time period is delivered or not can be determined only according to the current time and the delivery time stored in the block chain in association with the target time period, and the delivery time of all electronic messages stored in the block chain does not need to be detected, so that the delivery processing efficiency of the electronic mail is greatly improved.

Based on any one of the above embodiments, considering that the delivery time of some e-mails may be five years, ten years, or even longer in the future, in order to avoid the problem that e-mails cannot be sent, in one or more embodiments of the present application, a plurality of block chain nodes jointly run an intelligent contract for delivering e-mails, and jointly provide delivery service for e-mails; meanwhile, each block link point providing delivery service is rewarded; specifically, the method further comprises:

step A2, according to the letter delivery request, sending a delivery service providing request to each second block chain node, and determining a target block chain node for providing the delivery service for the electronic letter in each second block chain node through a consensus mechanism;

since the blockchain network includes a plurality of blockchain nodes, for the convenience of distinction, in the embodiment of the present specification, a blockchain node that receives a mail delivery request is referred to as a first blockchain node, and nodes other than the first blockchain node in the blockchain network are referred to as second blockchain nodes; it should be understood that the first blockchain node may be a second blockchain node in some scenarios, and the second blockchain node may also be the first blockchain node in some scenarios.

Further, in practical application, the specific consensus mechanism may be set by itself as needed, for example, the target blockchain node providing delivery service for the e-mail is determined in each second blockchain node through the byzantine fault-tolerant consensus mechanism, that is, a number threshold is set in advance, where the number threshold may be 50% of the total number of the blockchain nodes, or greater than 50% of the total number of the blockchain nodes; after sending a delivery service providing request to each second block link point, recording node information of the second block link nodes returning response data, counting the number of the second block link nodes returning the response data, and determining the second block link point corresponding to each recorded node information as a target block link node providing delivery service for the e-mail when the counted data reaches a set number threshold.

It should be noted that, since the consensus mechanism is a technical means well known to those skilled in the art, detailed processes of the consensus mechanism in this specification are not repeated, and reference may be made to the existing consensus mechanism.

Step A4, obtaining the required evidence of rewarding target block chain node;

in one or more embodiments of the present description, step a4 includes:

step A4-2, determining a first number of target blockchain nodes;

specifically, a first number of target block chain nodes is determined according to a consensus mechanism adopted in practical application; for example, using the above-described byzantine fault-tolerant consensus mechanism, the set number threshold may be determined as the first number of target blockchain nodes.

Step A4-4, determining a second number of certificates needed by rewarding target block chain nodes according to the first number, the delivery time and a preset rewarding mechanism;

wherein, the preset reward mechanism comprises information such as reward period, reward standard and the like, wherein, the reward standard specifies the fourth number of the certificates of the reward needed for providing the delivery service in the unit time interval, correspondingly, the step A4-4 comprises: acquiring current time, and determining the number of unit time intervals required by delivery service according to the current time and the delivery time; and calculating a second number of passes required to reward the target blockchain node according to the determined number of the unit time periods and the fourth number.

For example, in a unit time interval of "year", the reward standard indicates that the fourth number of the vouchers required to be rewarded by one blockchain node for providing delivery service of one year for a certain email is 12, and the first number of the target blockchain node is 20; the delivery time is 2029, 6/month 1, and the obtained current time is 2019, 6/month 1, it is determined that the number of the unit time intervals required for providing the delivery service is 10, and the second number of the evidence required for the calculated reward target blockchain node is 12 × 10 × 20 — 2400.

Step A4-6, according to the second quantity, sending a certificate transfer request to the terminal equipment of the sender, so that the sender can carry out certificate transfer operation through the terminal equipment;

when the terminal equipment of the sender receives the certificate transfer request sent by the first block chain node, the certificate transfer information containing the second quantity is displayed to prompt the sender to carry out certificate transfer operation; and transferring a second number of certificates to the first block link point in response to a certificate transfer operation triggered by the sender.

And step A4-8, receiving the second amount of the certificates transferred by the terminal equipment of the sender.

Further, corresponding to the step a 2-step a4, the method further includes:

and B, performing reward operation on the target block chain node based on the acquired certificate according to a preset reward mechanism.

It should be noted that the predetermined reward mechanism includes a reward period, such as a reward operation performed once a month, or a reward operation performed once a half year, or a one-time reward performed when the delivery time is reached.

Therefore, target block chain nodes for providing delivery service for the e-mails are determined, the corresponding certificates needed for rewarding the target block chain nodes are obtained, and the target block chain nodes are rewarded based on the corresponding certificates, so that the aim of stimulating each target block chain to continuously provide the delivery service for the e-mails is fulfilled; therefore, based on the decentralized characteristic and the reward mechanism of the block chain, the delivery of the E-mail is independent of a certain block chain node, but a plurality of block chain link points provide delivery service together, and the problem that the E-mail cannot be sent due to the fact that the certain block chain link point does not provide the delivery service any more is effectively solved.

Considering that some target block chain points may not provide delivery services until the delivery time is reached, in one or more embodiments of the present application, step B includes:

step B2, determining reward time and a third number of the certificates awarded to each target block chain node according to a preset reward mechanism;

for example, the preset reward mechanism includes a reward period of once every two months, and the reward standard indicates that the fourth number of the certificates rewarded by one blockchain node for providing delivery service of one year for a certain email is 12; and if the date of receiving the letter delivery request is 6/1/2019, determining that the first rewarding time is 8/1/2019, and the third number of the certificates rewarding each target block chain node is 2.

Step B4, when the reward time is reached, determining whether each target block chain node is in the state of providing delivery service for the E-mail;

because the block chain is specifically disclosed with a transparent characteristic, when a certain target block chain does not provide delivery service for the e-mail any more, the first block chain link point can acquire the state information that the target block chain does not provide the delivery service for the e-mail any more.

Step B6, if the target node is in the delivery service providing state, a third number of certificates are sent to the blockchain address of the target blockchain node in the delivery service providing state.

Therefore, before the evidence is sent to the block chain address of the target block chain node, the phenomenon of false reward is avoided by judging whether the target block chain node is in a state of providing delivery service.

Further, in order to effectively trace back the reward process, in one or more embodiments of the present specification, after step B6, the method further includes:

and step C, generating reward record information according to the node information, the third quantity, the reward time, the letter identification and other information of the reward target block chain node, and writing the reward record information into the block chain.

Further, in order to ensure that the e-mail can be delivered successfully, when the number of target block chain nodes in the delivery service providing state is less than the set minimum number threshold, the method further comprises:

and D, the first block link point sends a delivery service providing request to each second block link node except the target block link node in the delivery service providing state, a supplementary block link node for providing delivery service for the electronic mail is determined based on a consensus mechanism, and the supplementary block link point is rewarded based on the obtained evidence.

Further, in order to perform valid statistics on the certificate, in one or more embodiments of the present specification, step a4 is followed by steps of considering that since the target block chain node may not provide the delivery service until the delivery time is reached, and thus the certificate transferred by the terminal device of the corresponding sender may remain after the e-mail is delivered to the destination address:

step A6, generating the evidence obtaining record information according to the second quantity and the letter identification of the E-mail, and storing the evidence obtaining record information into the block chain;

correspondingly, after step S106, the method further includes:

e, judging whether the residual evidence exists according to the letter identification of the electronic letter; if yes, returning the residual pass-certificate to the terminal equipment of the sender.

Specifically, according to the letter identification of the electronic letter, corresponding certificate-passing acquisition record information and reward record information are acquired in the block chain; calculating the total amount of the awarded certificates according to the third amount in the awarding record information and the amount of the node information; and judging whether the calculated total amount of the certificates is less than the second amount in the certificate obtaining record information, if so, determining that the residual certificates exist, subtracting the second amount from the total amount of the certificates, taking the subtraction result as the amount of the residual certificates, and returning the certificates of the amount to the terminal equipment of the sender.

In a specific embodiment, for each e-mail to be delivered, a corresponding smart contract is deployed, as shown in fig. 7, the method comprising:

The foregoing description has been directed to specific embodiments of this disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.

In the 30 s of the 20 th century, improvements in a technology could clearly be distinguished between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Language Description Language), traffic, pl (core unified Programming Language), HDCal, JHDL (Java Hardware Description Language), langue, Lola, HDL, laspam, hardsradware (Hardware Description Language), vhjhd (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.

The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions.
