There is a unique function that has been added on DACPLAY which is called secret note . You may have a chance of drawing a prize from a pool after a note has been written . Let’s take a look at it .

Judging by the name , secret note is a note that contains contents which can only be read by the owners themselves . It’s essentially a private diary just like what you would expect on your mail box. However , there are more to it .

1.   The content of the note is encrypted . It can be assured that no one can see the content except the owner himself .
2.   The content is stored on the blockchain and saved in a distributed manner on the P2P network .
3.   You can freely store any kind of content without censorship.

The feature of safety and freedom on DACPLAY is based on cryptographic . So it’s safe to say that DACPLAY is one of the best tool to store your private information.

But……on the subject of DACPLAY , there must be some element of entertainment in this application .

Well , you can also draw a prize from a secret note . As you all know , there are cost for storeing information on the blockchain , that’s why the note writers must pay certain fees . In DACPLAY , there is also some PLS(token of DACPLAY) required whenever you publish a secret note on the blockchain as fees . However , 70% of the fees collected will be put into a pool where the prize for 8 winners will be returned from there .

DACPLAY will automatically draw 8 winners from those people who participated in writing notes every day . The winners will be rewarded in first , second and third prize . The fairness of the result can be assured since distributed random number generation of DACPLAY is in place . In fact , the function of secret note can be viewed as a prototype of on-chain games . Its economic model is to incentivize people to use the functions provided by the system which in turn would increase the activeness and engagement of the users.

For an on-chain game , parameters like the rule for winning a prize , the allocation of the prize and the frequency for drawing a prize can be set freely . DACPLAY is developing a smart contract function for general purpose . People would expect more games coming online once the function is available , since you can write your own game on DACPLAY with little experience on programming . You can generate streaming income from your game if it was proven popular . You can keep developing more popular games using the funds .

Please keep attention on DACPLAY for some of the interesting functions that will be added in the near term.
