MountainData BDW is working through a dApp, decentralized application, or SmartContract.
Anyone, anywhere in the world can interact with the dApp
It helps you to write some data directly in the blockchain.

When you do so, some fees are needed by the network to secure the transaction and proceed the writing.
The data entry will then be stored in the blockchain forever, without any other fees.

You can build your own personnal database! Why is it interesting ?
You don't need to run a server
No maintenance
No recurrent fees
Awesome isn't it ? :)

No. The data sent on the blockchain are immutable.

No. The data sent on the blockchain are immutable.

The best way is to keep the account address used to insert the data. With this address, you can get back all the entries you sent.
To help you remember the account address, you can create an alias for your address
If you know the ID of your data, you can search for it here Search by ID
If you used a specific keyword or nickname, you can search for it here Search by Keyword

MountainData have a lot of use cases. First of all, it is your own fully decentralized database. You can use it to store any (non private) information that you don't want to lose. These data are forever accessible by multiple ways : By your own website, webApp, app or even Waves dApp. Example, if your website host links or articles, you can easily move these elements on the blockchain by using the MountainData BDW, and get your element through the API. As these records will stay there forever, it's secure, costless and don't require any maintenance.

MountainData can be used as a proof of source, to certify that an article, link or memo is an original one and has not been counterfeit or updated by someone else.

MountainData can be used as a proof of authenticity. Let’s say we’re in 2008 and you just run bitcoin.exe for the first time. You can use MountainData to write « I am Satoshi and I’ve just run the first Bitcoin node with bitcoin.exe for the first time. » As there is a transaction timestamp, that would have been an immutable certification that you are Satoshi.

In the same mind, a watchmaker will be able to certify his watches and publish updates when maintenance occur. So there's no doubt about the origin of the product and how it has been maintained. MountainData can be used as a link database. If your website is using a collection of links, you might consider storing them in the blockchain to secure them. With the API, your website can retrieve your links easily and without any cost. If your website is using a great amount of links, you can cache them to make it quicker and sync them periodically.

If you are a journalist or a political opponent in a country without freedom of speech, you might consider using MountainData to publish your articles or news. MountainData is censorship resistant : No one can prevent you from publishing informations, nor can anyone stop people from reading it. Any question regarding this use case, feel free to contact our Press contact. This contact will help you to publish safely and protect your identity.

If you are a Waves dApp developer, you can use MountainData tu create a static oracle that is static and immuable. It's quicker and cheaper than create a custom dApp, insert the parameter, and secure it.

MountainData can be used as a memo database that will never disappear. So if there is something you want to remember forever this is the right tool.

Yes there is an API. You can use MountainData to get data from from the blockchain for your own website, webApp, App or even Waves dApp.
We will release all the sources so you can build your own API with your own server :)

You can get data from an ID, and list data from a specific account address. See API for more informations.
