Nice to have the planing updates for the day :-).
Thank you.

Hello, I'll translate this thread on Polish. Please notice this reservation in your google spreadsheet. I think that translation will be done around this weekend

MongoDB's speed depends on how you organize your data. If you organize it like a relational database, where every piece of data is in it's own document, then sure, it's not much faster than SQL, and it'll use more resources.

Now, if you store similar data in the same document, it takes much less time to retrieve. Sure, you retrieve more data, but, thats typically less of an issue than the speed at which that data appears.

For example (Simplified):
Say all it took to store the blockchain was a main table (blockchain), and a transaction table. Transactions are parented by blocks, blocks relate to each other by referencing the prior block (this is pretty close to accurate, although there are some other tables that go along with this in most implementations)

In order to pull the transactions of a specific block, you have to query the main table for the particular block ID, then query the transactions table for each transaction that relates to that black. Standard SQL. The entire table of transactions need to be queried.

With a Document Database (like Mongo, or LevelDB), you store the transactions on the block itself, instead of a separate table. In this instance, a query would take much less time, how much less depends on the number of transactions, more transactions, the greater the time difference. Query the block, get the transactions. MongoDB even allows for only pulling back the pieces of the document that you need, so you don't waste bandwidth.

In addition to the speed, you write queries for MongoDB in javascript. So Rise will initially be an entirely javascript stack. We will be supporting other languages for DApp development, but they will be interacting with the DB through Rise APIs, which are all javascript. Any language that can consume a JSON / REST API can be used for Dapp Development, and MongoDB provides the data storage.

Hopefully that makes sense. I'd love to talk to you more about it in our chat if you would like. https://www.hipchat.com/gtjX3uPYE

For Document DBs, there are a couple of options, but I've been working with MongoDB for a very long time, and I enjoy working with it, it's engineers and support staff, and with it's ORMs in NodeJS. I considered Cassandra, as well as CouchDB, but couldn't find enough differentiators to switch at this point. Cassandra would be good if every Node was going to talk to the same database, since it is designed to scale horizontally, but then that defeats the whole purpose of the blockchain.

Thanks the OP has been updated wtih your Indian translation.

Why MongoDB due to centralization of the nodes? Mongo isn't really a fast DB and certainly uses more resources.

Once we have the funds available, there are multiple developers I plan to bring onboard. Just need the funds to do it with.

Yes, we actually had a conversation with Max at Lisk about that briefly a few days prior to ICO. We are going to be moving to MongoDB for the backend, which is more in-line with what we want to do. I wrote about that in the Whitepaper I released on Saturday.

I was originally planning on streamlining some of the processes for SQLite, and hoping to get enough of a performance improvement out of it, but it's not likely that it would be enough to reach the network speeds we want to see.

LevelDB is a good option if we were going to keep to the flat-file based DB system. I'd rather just switch over to a full on OODB and go from there. More flexibility, and has some interesting encryption mechanisms.

Update
If you would like to see what we are currently working on, please take a look at https://risevisionfoundation.atlassian.net/browse/RW-25?filter=10100 - This shows all things currently in progress. Our Jira and Confluence instances are also open to the public for sign up, please feel free if you would like to contribute to sign up and get involved. We are still in the process of migrating over to Jira and Confluence, so it will be a little bit before all of our data and planning items are uploaded. I plan on doing that this week.

Plan for the day:

• Fix Firefox incompatibility
• Add referred transactions to the profile
• Change BTC decimals to 8
• Add the BTC / USD Investment Values to the ICO page
• Add QR code to profile for Investor BTC Address

How many developers are working on RISE? I think you should expand this in the upcoming weeks if you want to get serious about this project - also a friendly note you should start using some other database from the start (levelDB for example) - LISK moved away from SQlite to PostgreSQL as there were some issues with SQlite and since you are using SQLcipher, which is just an extension of SQlite you will run in the same problems as well.

When you fixed a bug with the inability  Join to ICO in Mozilla Firefox, but I should not install a new browser to take part in ICO ?

Let's spread the Word - here is my latest addition to RISE:

@Risevision
Indian (hindi) language translation has been done.

Please update the O.P.

Yes. It works, no mistake with your share but yes, looks strange.

and I sent 0.15BTC for ICO. +25% bonus does not hurt)

I'm still undecided. I'll wait a few more days. 

I sent 0.1BTC for ICO

Very good, congratulation :-).

If there is enough interest displayed during the ICO then the exchanges will just add us. We won't know before they do unless they have questions.

Looking at that closer, the number appears to have 9 digits and not 8. hmm. So it's probably priced at .00000034 ??

Was amaze the price of RISE is already 0.000000336. Hope the value will be more after the ICO.  Which exchange site dyou guys plan to enlist it?

We declined paying him already

Also everyone is encouraged to come and chat with us here... https://www.hipchat.com/gtjX3uPYE ask any questions and just be part of forming the RISE community.

Please, don't pay anithig to this guy to be on his websites (or something else) : it is a bandit.
