ORIGINAL POST
That is it, I want to start the rescue of devtome.com.

A little background about me, I'm proud member of devcoin community, being granted several ongoing shares for my contributions and assignments (Devcoin Share List, Marketing, Investor Administrator, Node Maintenance). I'm really frustrated because my assignment of "Investor Administrator" is currently blocked, since people running devtome.com is not responding, that makes impossible to deploy my code. Also, I like to contribute to the wiki but current annoying bugs make it really hard.

Ok, this is the plan:

1. Diagnose current situation
2. Propose solutions (only what you can actually do, don't expect help from people running devtome.com)
3. Fix this mess
4. Celebrate!

My previous post: "[DVC] What happened to Devcoin leadership!" (https://bitcointalk.org/index.php?topic=1288592), demonstrates that people running devtome.com "just have no interest in keeping them ticking, and don't respond when you try to get them to do their job." as Hunterbunter said already (https://bitcointalk.org/index.php?topic=233997.msg13277774#msg13277774)

First things first, we need to diagnose current situation of Devtome.com, please share your thoughts.

Let's make it happen!
3  Alternate cryptocurrencies / Altcoin Discussion / [DVC] What happened to Devcoin leadership! on: December 14, 2015, 04:35:52 AM
Dear Devcoin leaders,

I joined DVC community because I believe in it. Actually, my project http://ophal.org got an spike in motivation thanks to the Devcoin Foundation, and for sure you know about the several people that write in devtome.com, they created something with amazing potential!

Yet this project needs leadership! devtome.com has a bug that can't be fixed yet, coinzen.com is still dead, ghash.io stopped mining DVC, we only have two exchange markets left, etc.

Btw, 3 or 2 satoshis per DVC are still not 0, we can make something to transform DVC into what it was created for.

Please do it! Raise leadership again!

Kind regards!

5  Alternate cryptocurrencies / Service Discussion (Altcoins) / Is using minergate safe? on: July 04, 2015, 07:10:55 PM
That site looks interesting but I'm not familiar to Cryptonight and webmining. Also, some currencies they mine are dead.

Feedback appreciated.
6  Alternate cryptocurrencies / Altcoin Discussion / What products/services do you buy or would buy with altcoin? on: May 28, 2015, 04:40:16 PM
Proposed products:

- Branded t-shirts
- (Add you idea)

Original post
I'm so tired of all the complains about altcoins. I'm really upset! So let's use that energy for something useful.

Coins become currency when they are used for real stuff, a.k.a: buy/sell products and/or services. Then, why don't you just tell us what would you like to buy.

NOTE: This thread is to request services/product, not to promote the excisting ones. Thanks!
NOTE #2: If you think that altcoins are not for you, please do not comment, we want ideas, not complains.
7  Alternate cryptocurrencies / Marketplace (Altcoins) / I'll buy whatever you offer me for 100k DVC (Devcoin) or 2.5k BURST on: May 11, 2015, 11:25:34 PM
Yes, anything legal! And I can buy several times.

Just offer me a digital product or a service, share your DVC/BURST address and you'll get 100,000.00 DVC or 2,500.00 BURST.

The only requirement is that you have at least 30 points of activity.

NOTE: I'm not willing to buy piracy/cracked/ilegal stuff. Thanks!
8  Alternate cryptocurrencies / Mining (Altcoins) / Should "4commit" be considered another way of "mining"? on: April 09, 2015, 08:47:30 AM
Proof-of-stake coins call it minting instead of mining, and there are coins offering bounty for each commit, say primecoin and peercoin.

Perhaps this deserves to stablish a new name: "4commit", or "4commit mining". What do you think about it?

The current value of DVC is 4 satoshis, and is going down to 3. At first sight it means that nobody wants it, but if we carefully check their community, it looks like they are preparing something big. So it is a good time to buy DVC! Buy cheap sell high = WIN
11  Alternate cryptocurrencies / Announcements (Altcoins) / [SC2] just another Proof-of-Storage coin on: July 24, 2014, 01:00:11 AM
Hey there everyone!

A little background first

My wife is environmental engineer and she hates ASIC miners, I born in the Southamerican Andes and my city is suffering climate change, so anything that is not energy efficient is out of discussion for us. Yet we are not green-tards, we just try to improve our consumption habits. This is a mess! I know!

So, in short, Proof-of-Work is not for us, period. Let's try to build something that is energy efficient.

Proof-of-Storage

There are plenty of gigabytes not used in millions of computers connected to the internet, some of them use BitTorrent, but what about private files? Lets think on system that can compress, split, crypt and distribute several copies of my private data over the Internet, securely. A system where uploads and downloads are always free and where nodes providing storage service get rewarded with SC2 coins.

I spend yesterday afternoon and evening designing the idea, sorry if this is too drafty but guess is time to release the idea since my background on cryptocurrencies is yet too short:


  • file storage, uploads and downloads are always free!
  • 2^21 SC2 "pre-mined" to pay initial seed nodes infrastructure
  • the network makes sure that each file has at least 10 copies of each chunk
  • proof of storage:
     
    • get rewarded to proof storage of files
    • node stores each successful confirmation in the  blockchain
    • 8 confirmations needed each 32 min to consider the chunk is really stored there
  • the confirmation:
     
    • confirmations older than 8 min will be rejected by nodes
    • created by the node that stores a copy of the chunk
    • the node randomly picks 32 positions within the chunk, they are concatenated along with the microtimestamp and hashed with SHA256, which is then used as confirmation key
    • confirmation database:
         
      • chunk id
      • confirmation id: UUID
      • confirmation key
      • microtimestamp
       
  • the blockchain
     
    • a new block is generated every 2 minutes
    • a block contains
         
      • all found confirmations from last 8 min
      • all transactions from last 8 min
       
    • nodes find to each other by broadcast
  • the transaction
     
    • address to send coins from
    • receiving addresses and what amount should each receive
  • the SC2 address
     
    • 'SC' prefix
    • long-random-key
    • 'SC' suffix
  • the node
     
    • stores a full copy of the blockschain
  • the storage node
     
    • just like any other node
    • stores copies of random chunks
  • the wallet
     
    • has a RSA-8192 pair: public-key and a private key
    • the public key is used as the AES key
    • stores the the list of chunks that compose the file tree
  • the chunk
     
    • each chunk is a part of a file
    • compressed with xz
    • crypted with the private wallet key
    • named after its SHA-256 hash: [sha256].xz
    • no need duplicate storage of identical chunks
    • max chunk size starts at 1MB and varies by the total file size, the rules might change overtime as internet connection speeds improve worldwide
  • the file descriptor
     
    • split in chunks
    • named after UUID: [uuid].file
    • JSON format
    • contains:
         
      • filename
      • filesize
      • list of chunks that belong to the original file
       
  • the file tree
     
    • is just another file
    • contains the file tree (directory structure)

And that is it, willing to get your feedback!
