Topic: [ANN] [PASC] PascalCoin, true deletable blockchain - V3 Hardfork on block 210000 - page 354. (Read 990744 times)

 Thanks for all your work and dedication.  My last 1200 coins are on the way to account #1-26

3k Pascal coming your way

Do you mine?
Do you want to profit with Pascal Coins?

If you don't want to help with your time, please help with donations of your mining winnings to Pascal account 0-10 that will be used for future project necessities.

Everybody wants a great future, contribute with time or with donations


Thanks

Note: Account 0-10 will be used, exclusively, for project necessities. Dev will be the guardian of this account.

Miners alert

I've detected that only very few of all miners have 4004 port open.

Please, contribute opening your port!

If you don't open your port, you don't have guarantee to stay correctly connected and perhaps you're wasting time, mining for nothing.

Definately please everyone retweet and give help to the developer we need this to get added to exchange and create other services.

Thanks so much developer, everyone please offer help this is vital to our development!

Its even higher now 120GH/s.

Hi Guys.

JSON-RPC calls are ready! ... but prior to send them to exchanges or third party devs I need 3 things:
- Hard Test (QA)
- Document calls at Wiki
- (optional) Develop a simple (but pretty) website to show something similar than you can see in app wallet: Show Blockchain/Operations/Pending operations ...
  - This website will get data making JSON-RPC calls to PascalCoin

So, I need help!

If somebody is interested in testing/documenting please send me a PM
Note: To develop website, It's important to test RPC-Calls prior to understant how it works.

What will we do?
- I'll send you a binary (Build 1.1 beta) and a File containing JSON-RPC source code with some instructions about "how" to interpret this source code
- PascalCoin will use standard JSON-RPC 2.0 with some changes needed to test properly ( http://www.jsonrpc.org/specification )
- You will test functions that you will find in the source based on examples I'll send:
  - Testing using "chrome" or "Firefox"
  - Testing using terminal
  - If you want to create something better to test RPC calls... perfect  (local website???)
  - When you find a "bug" or something wrong... send me a PM / email
- While testing, you will need to document it in "Markdown" format. I'll tell how-to. It's easy and I'll give you an example

If you help me, next week JSON-RPC calls will be ready!

I think this is a simple help you make to me but a lot of help for PascalCoin comunity

Thanks!

means your GPU is too old......

I've got this

is it possible to know which changes needing for donation 0.1 BTC ?

This application is a Node, a Wallet  "AND A BLOCKCHAIN EXPLORER". (All-in-one)
This message was because in earlier versions there was a bug when saving database information, and crashed application.

Technically, Pascal Coin uses a safebox, modified each time a new block is generated in the blockchain. When this happens, safebox is updated with block operations, and then generates a new "SafeBox hash". After this, the entire blockchain could be deleted without losing double spending efficency, because balance of each account is included in SafeBox. SafeBox size is growing in 5 new accounts per block, so, size is controlled

Do you understand?

Edited: You can check it doing this steps:
- Open Build 1.0.8 (last stable version with an Microsoft access Database)
- Wait until node status = running
- Open microsoft access and open database blockchain (C:\Users\(user name)\AppData\Roaming\PascalCoin\pascalcoinB03.mdb)
- Delete all rows in table "tblockchain"
- Delete all rows in table "toperations"
- App will work properly, but, of course, will not show historical blockchain and/or operations due you've deleted them
- Conclusion: Core does not need historical blockchain
You cannot test it on build 1.0.9 because version 1.0.9 uses a self made database file and I've not developed an database file editor, but you can develop it by yourself using source code at github.

In that case why did pineapples need Lafu's blockchain download to get the wallet working, and why did you instruct users to replace the pascalcoinb03.mdb for a downloaded database to get the wallet working. If it was to fix a temporary bug what was the bug and how did it stop PascalCoin working perfectly without a downloaded blockchain?

Is this nomarly?

Reading White Paper you will see that Pascal coin is not a "mini-blockchain".

PascalCoin core DOES NOT NEED the blockchain. CAN BE DELETED. ALL AT ANY TIME !

But, of course, the blockchain is usefull to see historical operations, but, I say again: You can delete ALL previous blocks from the blockchain and PascalCoin will work perfectly, without double spend problem.

So... that is not a mini-blockchain. Sorry. 

Cryptonite was the first coin to implement a mini-blockchain scheme. It uses a decentralized balance sheet approach to keep the blockchain tiny. I don't understand exactly how the scheme is implemented, or how pascalcoin's lack of historical operations scheme is implemented, but both coins are based on the goal of removing the need to maintain an ever growing giant blockchain. Despite its mini-blockchain scheme cryptonite's not in the top 100 coins. Pascalcoin might need more than a lack of historical operations to get into the top 100.

Because, CUDAminer is not optimized for GTX1070.
On my single GTX 1070 I'm mining average 750 MH/s. I have made some changes in miner source and recompiled.
