# Anonymity mining
|
||
|
||
***Please, keep in mind, that you read historical deprecated article. Anonymity mining ended more than two years ago and wont be available anymore.**
|
||
|
||
Anonymity mining was an incentive to increase the level of privacy in any coin-joining or coin-mixing protocols by rewarding participants anonymity points (AP) dependent on how long they hedge their assets in a pool.
|
||
|
||
{% hint style="warning" %}
|
||
_Tornado Cash anonymity mining program began on December 18, 2020 and ended on December 18, 2021._
|
||
{% endhint %}
|
||
|
||
Individuals deposit to any one of the anonymity pools that are supported (ETH, WBTC, DAI or cDAI) and are rewarded a fixed amount of AP per block, over the period their deposit remains in the pool. These points can then be exchanged for TORN once claimed.
|
||
|
||
### Anonymity points (AP)
|
||
|
||
_Readers should be aware some lower denomination deposits at the time of writing, do not produce a positive return due to the gas costs required to withdraw, redeem and exchange anonymity points_
|
||
|
||
One of the community members created the resource of [a mining spreadsheet 13](http://web.archive.org/web/20210727093742/https://torn.community/t/anonymity-mining-spreadsheet/720) that helps calculate annual percentage yield’s (APY’s) for each pool and each denomination set within, through estimating the fees required to claim a reward. **It is highly recommended to view this resource and plan one’s course of action before expecting to earn yield.** At the bottom of the spreadsheet, you can view each pool by selecting the associated tab.
|
||
|
||
### How to earn AP
|
||
|
||
1\. Decide what amount and asset to deposit by selecting it through the dropdown menu, before clicking on "Connect" and "Deposit".
|
||
|
||
|
||
|
||
2\. Take a record of your depositing note and back it up safely, **do not share this with anyone or risk losing your deposit and reward.**
|
||
|
||
|
||
|
||
3\. Generate the proof and submit the transaction.
|
||
|
||
4\. Your deposit should now be viewable on the bottom of the page, you can track how much AP it earns here; remember the longer your deposit remains active, the more AP you earn.
|
||
|
||
|
||
|
||
_Notes that are active (not withdrawn) are known as “unspent” notes._
|
||
|
||
### How to claim AP
|
||
|
||
1\. First you must create a mining account and store those credentials on-chain for easy recovery (requires a transaction), **like depositing notes, you should never share your mining recovery key with anyone** and ensure to back it up in a safe place. This feature is not supported by hardware wallets so it’s encouraged to store the information as presented\_.\_
|
||
|
||
|
||
|
||
2\. Take an active deposit through providing an unspent note and withdraw to an address of preference and decide whether to use a relayer or not (_to maintain a deposit’s anonymity it is always advised to use a relayer_), this will bring the note into a “spent” state.
|
||
|
||
|
||
|
||
**Remember to still keep your depositing notes a secret even after withdrawing, as they still retain the ability to redeem AP.**
|
||
|
||
|
||
|
||
3\. Visit the mining route of the application and enter your spent note, you may be faced with one of the following situations.
|
||
|
||
* **The ability to claim your spent note**: click the “Claim reward” button and submitting the transaction either by using a relayer or not, once confirmed your AP balance should update to reflect the action.
|
||
|
||
|
||
|
||
* **The inability to claim a spent note:** _“Warning: The note is not yet ready for anonymity mining. You can wait few days before trying again”_ - This means the Merkle trees are out of sync and require a transaction to be updated.
|
||
|
||
|
||
|
||
Updating the trees can be an expensive process, **it is recommended that users with small deposits wait for the larger miners to update the trees, this could take anywhere from a few days to a week**. If you want to view your event relative to the current pending batches. Click the _“Show mining note information”_ hyperlink, here you can also pay the transaction fees to sync the tree relative to your withdrawal through the “Update trees” button.
|
||
|
||
|
||
|
||
### How to exchange AP
|
||
|
||
1\. Navigate over to the “Swap” tab on the mining page which can be accessed through the second navigation bar from the top of the page.
|
||
|
||
|
||
|
||
2\. Enter the amount of AP requested to exchange or select the “Maximum” option to convert your active balance. Below this input, information regarding the current AP/TORN rate and reward output will be displayed. Provide an address of preference to receive the reward, finalize by generating the proof and submitting the transaction through a relayer or not.
|
||
|
||
|
||
|
||
3\. If all steps were followed correctly, TORN will be transferred to the address of preference provided in step 2 of this section.
|
||
|
||
### Closing remarks
|
||
|
||
Congratulations, you have successfully participated in anonymity mining!
|
||
|
||
It is always recommended to plan when deciding to mine any of the anonymity sets, users should also be aware that the [AP/TORN rate](https://duneanalytics.com/luckyallocator/Daily-AP-TORN-Rate-v2) is dependent on supply and demand, therefore, **the more people that claim the higher the rate becomes, and the less people that claim the lower it becomes**.
