AltSheets Block Explorer Extension v0.2.2

 - for Ethereum based coins -




Most important at the beginning: This is not all my own work.
It is a fork of the new "EthExplorer (In Progress)"
(etherparty / explorer 0.1.0)

Then however much extended by AltSheets.

Portable to your Ethereum based coin.
Make a crowd funding session in your thread.
Involve your devs. Then send me a fair offer.

           coefficient analysis needs many coins to iterate their block chains

thx to LaudaM and ndnhc for showing me the way how to do this

What you see is what you get = study the images:

Part 1: My work

Types of pages



actually the most important message - to your community, and to coinmarketcap.
You will stay below rank 605 until you report a /supply/ function.

---



Quizz: How many times has the "on which block are we?"
question been asked in all of bitcointalk?

---



No wonder we let our computers do the work if expressing the
difficulty of last block's lottery needs such a large number.

---



Total number of coins rewarded for producing all that hot air since genesis.

---



All money there is.

---

... if the total gas consumed in the block up until this point exceeds the GASLIMIT, return an error.

(https://github.com/ethereum/wiki/wiki/White-Paper#blockchain-and-mining)

---



More information than most of you might ever want to see.
Still ... this pic is clickable.

---

(New?) Coefficient:
Have a long look at the center 0.6565.
Might only be me - but I had never seen that representation before.
(You know about a table with many coins? --> I do a semiscientific analysis of this coefficient)

The "Total difficulty" is the sum of all difficulties until that block.

The lower part queries the ethereum node about its version, and status.

Footer:

This footer is shown on all new pages contributed by AltSheets.
The links are going to /ABEE/ and /give/.

And the very bottom footer on all pages ... is the original one, and goes to fork me on github.

v0.1.0 is under MIT license, while my 0.2.2 must first generate some money now.
What kind of license is good for that?


Part 2:
Pages existing in v0.1.0

The following pages were ~ ready. I had to understand them all,
to learn how to port this to other Ethereum based-coins.

Then I made a few additions, but not many.

My main work here is the service for you - to port it.


(pic is clickable)

I added:

(previous) (next)
and
Number of Transactions.

NO: The transactions are NOT visible, nor clickable - yet.

YES: Miner's address (see below, part 3), and block number are clickable.


---


(pic is clickable)

Nothing added to the v0.1.0 original.


Part 3:
Work in progress



From what I forked had no address information at all.


As everything here (I am new to node.js) it took me long today,
to code the framework for this page - but now the beginning is done.

And you can see your balance - anyone's balance actually. That's better than nothing.

To continue might be easy, or non-trivial. Of course possible - but more eth learning necessary.
I have not yet found an easy way to just ask web3.eth for the last 10 transactions of an account -->

ERFC #0001

ERFC =ethereum-request-for-code  *lol*
The Ethereum team could please build (for all of us) an easy
web3.eth.Get_Account_Transactions(account) and
web3.eth.Get_Account_Transaction_Ids(account)
(like in NXT or HZ).

But also: Might only be me. It sure exists,
and I have simply not found out about it yet.
Only my first week with Ethereum ...

It really doesn't exist. Ethereum coders must be funny people,
to launch a coin without that function. The only API function for
addresses & transactions is getTransactionCount,
which I have included into my new address page.

Who?

other projects

(AssetGraphs NxtHacks2015 new ready version v2,
ChainCountDown, Shareholders.py,
AssetParser, and B.E.E.f.A, and bamm.py, ...
and most of all: AltFolio, my first and most ready one.
Buy my AAsset if you believe in one of the above.)

Superbusy guy - perhaps that makes it better understandable,
that I am offering you a ported block explorer "as is",
exactly how shown in the pictures here.

Yet uncoded stuff is not part of the ABEE offer - it might or might not happen.

But of course, for 15 dollars per hour, I can code anything for you.
In my known perfectionism - precision, code comments, documentation.

What's next?
Much is possible.
A full blockexplorer like the celebrity ones ... is not done in 2 days.
Not my scope even. I might have to discontinue to work on this - IF no coin buys it.

The original goal was mainly picture #1 at the very top, plus learning how to port it.
But then my enthusiasm got the better part of me - and this is what came out.

You
can get involved:

Help to refinance my immense amount of work to get here
(which will very probably never really pay off, no illusion) ...

... and allow me to extend it further ... by launching this in your
favorite ethclone thread. Do not expect coin devs to solve all
questions for you, and at once. Get active, get some people
together - and spontaneously crowdfund (*) what you wish for:

    ... blockexplorer ... blockexplorer ... blockexplorer ...

was the one repeated outcry when I skimmed through the EXP thread.

Why and How to buy it:

And here is where my ABEE comes in. [ABEE] is NOT a replacement
of a full-fledged block explorer - that can be added in week 3, and
needs deliberation, shopping around, comparing, etc. ...

However, while the devs are superbusy in the first days, my above
ABEE can already help you a lot. And later it can be useful as a
backup block explorer. No, it is not answering all questions,
I am not promising pink unicorns. Transparency honesty fairness trust!

It is CSSed - so your designer can go wild on it :-)

To secure me, I take 50% upfront. Me failing with porting it to your coin is
VERY improbable (~ 1% probability) - in that case, I'll give the money back!

TL;DR: You get what I show above, not more. But ported to your coin NOW.

Of course, for a reasonable time, you also get extensions that
I might or might not write. All conditioned on ... earning money
with this -I feel beautiful- piece of work.

If anything is ambiguous, please ask! Really welcoming your opinion on this.






(*) crowdbounty:
= "How to emancipate yourself from premines, and still get development done --> collectively."

     (1) Mention it: "Let us buy a block explorer together."
     (2) "I pledge _.__ BTC for a block explorer, who else?"
     (3) repeat 1-2-1-2-1-2-1 ... :-) Needs a bit of holding the energy for it, but often works.
     (4) Someone says "why not also our coin?". Yes! (Now the devs might pledge some too)
     (5) The most trusted person(s) become escrows, one BTC one CLONE.
     (6) By now, you have found several options already. Vote, choose one.
     (7) And hopefully, you make me an offer, too. For ABEE. Thanks!

If deal happens, I share 5% each with the two people who had done (1) and (2) first.

How does all this sound?
Thanks a lot for your patience, and attention.

Version v02 added the 50%, and full refund condition, and paid coding price.
Version v03 TOC

[altsheets]

(New?) Coefficient:
Have a long look at the center 0.6565.
Might only be me - but I had never seen that representation before.
(You know about a table with many coins? --> I do a semiscientific analysis of this coefficient)
The "Total difficulty" is the sum of all difficulties until that block.

Let's call it AltsheetsCoefficient - for now.
(Or please show me a publication/thread where it was mentioned/analyzed before.)


I have contacted people, to get my hands on that data.

From one of my answers:

I tried to find some explanations for you:

"The main branch is defined as the branch with highest total difficulty, summing the difficulties for each block in the branch."
https://en.bitcoin.it/wiki/Protocol_rules#Blocks

"The higher the total difficulty, the harder it is for an attacker to overwrite the tip of the block chain with his own blocks"
https://en.bitcoin.it/wiki/How_bitcoin_works#Bitcoin_Mining

> Isn't it something linked to ethereum-based coins?
Yes, also. But:

It is part of Satoshi's original concept.
(The above links lead to bitcoin.it)

Bitcoin has it. The 500++ clones have it. In the mining protocol.
And also newly developed coins (e.g. NXT, ETH) have it.

But as the number itself is even larger than the difficulty ... and (until now,)
most people could not really relate to it ... it is not often talked about, I guess.

Let me see...

I have no bitcoin full node (the current blocksize is too large *muahaha*), but
I have started my mintcoin wallet (which inherited the bitcoin RPC API), to try it out:

Code:

> getblockhash 1711901

}

oops. It is really not in there.

I am surprised.


So then it can only be known by summing up the whole blockchain.
i.e.

Code:

blockheight=1 # not sure if 0 or 1
breakWhenNone="nextblockhash"
printEvery=10000
difficulties={}

try:
    while true:
        blockhash  = coinRPC ("getblockhash", blockheight)
        block      = coinRPC ("getblock", blockhash)
        difficulty = block["difficulty"]
        difficulties[blockheight] = difficulty
        if (not block.has_key(breakWhenNone) or block[breakWhenNone]==""):
            break
        if blockheight % printEvery==0: print blockheight, 
        blockheight += 1
except Exception as e:
    print "exception happened: %s" % e
    print "but at least we could save the results unto here:"

Now calculate the sum, show it, and save the results, to send them to me:

Code:

print
lastblock = max(difficulties.keys())
totalDiff = sum(difficulties.values())
print "Total Difficulty of Block %d is %.1f" % ( lastblock, totalDiff )

import pickle
pickle.dump(difficulties, "coinname-difficulties-%s.pickle"%blockheight) # keep, and send to AltSheets, thx !

import json
define coinRPC(command, parameter):
    answer = somehowAskTheCoinWallet ("%s %s" %(command, parameter))
    return json.loads(answer)

Of course, this is only a rough sketch. Quick.

Additionally I would probably
* catch the exception earlier - when the wallet is temporarily unwilling to answer, then wait ... repeat
* implement it threaded, to ask 1000 questions in parallel
* refine it on the way...

TL;DR:
I have had a -possibly clever- idea. For now, I call it "AltsheetsCoefficient". Scroll to the middle of my OP.
To analyze it, I would like to have a table with the "Total Difficulty" of 200+ coins:
{coin acronym: "ETH", block number: 238999, difficulty: 6405772712069, total difficulty: 1005033336244056811}

I have an instinct, that it might help us all ... to see this analysis & comparison of coins.

Anyone running many different wallets? Let's build this together!

And publish an article together about it on arxiv.org - will be interesting to see what they do with pseudonyms.

...

With the first step of my ABEE I had been targeting at something much less than that -
mostly because I was forced to save time, and money - but still be able to answer the
most urgent questions. Especially reporting the total /supply/ back to coinmarketcap is of
paramount important for a new coin, if it wants to get above rank 600 in the CMC table.

And to see "on which block are we", "how many confirmations has that transaction", "what is
the difficulty", etc. ... a simple (block, transaction, chain) lookup is already more comfortable
... than the empty nothing - right? Plus in 0.2.2: "How many coins does XYZ own" = (address)
lookup now, too. Simple version, but working. (Other clones: contact me!)

In the current state of the code, ABEE is a good alternative, especially for the first days.
And for later, as a secondary block explorer it also makes sense IMHO.

Perhaps driven by my own curiosity, I want to see some fancy analysis of etherclone blockchains.
Might happen, lots to explore. But ABEE's further development is frozen for now, due to lack of funding.

...

But now finally ... back to my own projects.

 

... so ...

But ABEE's further development is frozen for now, due to lack of funding.

... but of course, you can simply directly fund the further development:

Progress!

• ABEE will be ported to SOIL ! Together with crowdfunding, finally
  found agreement with soil&abvhiael of soilcurrency. See SOIL thread.
   
• Upgraded to newest node.js, geth, gsoil, both Win & Linux - whew,
  all this (non-coding) stuff costs so much time ... still syncing chains.
   
• in nodejs/angularjs I coded a clever transaction list for non-empty blocks.
  See below.

ABEE v0.2.2a

new BLOCK page with transactions!




/#/block page now contains transaction list,
and all linked to each transaction page.

Transactions

Proper error page when transaction does not exist (yet):




Blocks

Proper error page when non-existent blocknumber:



Each block can have 0, 1, or 2 uncles included:


Try blocks 320174, 320003, 32, 58, 72, ... or find them yourself:

Code:

for (i=320000; i<330000; i++) { U=web3.eth.getBlock(i).uncles; if (U.length>0) {console.log(i, U);}; if (i%500==0) {console.log(i);}; };

Show transactions in each block:




Chain

Chain-info fully ported to soil; also show average of past 100k blocks:

The mined, and suppy numbers are identical to http://explorer.soilcoin.xyz - Calculated like this:

Code:

var	REWARD_CHANGED_AT_BLOCK = 263707,
	COINS_PER_BLOCK_PHASE1 = 8,
	COINS_PER_BLOCK_PHASE2 = 4,
	PREMINE = 1000000;

var mined  = function(blockNumber){
	var coins = 0;
	if (blockNumber < REWARD_CHANGED_AT_BLOCK) {
		coins = COINS_PER_BLOCK_PHASE1 * blockNumber;
	}
	else {
		coins =  COINS_PER_BLOCK_PHASE1 * REWARD_CHANGED_AT_BLOCK;
		coins += COINS_PER_BLOCK_PHASE2 * (blockNumber-REWARD_CHANGED_AT_BLOCK);
	}
	return coins;
}

var supply = function(blockNumber){ return PREMINE + mined(blockNumber); }

... extracts from a PM, then slightly edited ...

... that you have done some updation to the etherparty EthExplorer

I have indeed.

Using his 0.1.0 base system, from the MIT branch of his repo ...
I have put a lot of work into it, to bring it almost one and a half steps forwards. Not yet two steps, but ... 1.3 steps :-)

So for example, my address balance extension works like a charm.


I have ported it to SOIL, and it is running there since New Years Eve, and without any problems: http://abee.soilcoin.xyz/

My address balance page looks like this.

There is a whole new advanced info page about the chain, the node, supply, etc.

... plus tons of little improvements, on the previously existing pages.

There are also API results pages, about supply, blocknumber, etc. --> which you need to get properly listed on coinmarketcap.

For all possible URLs, click all links in this posting.



Disclaimer: Ethereum does not provide a "getTransactions(account)" function, and I have not had the time nor funding yet to build an additional backend (that would be scanning the whole chain, to collect all transactions of all accounts) ... so the missing "holy grail" is:  transactions-per-account. In ABEE you can NOT lookup the transactions that were sent to or sent from an account. (I was actually really surprised to find out about that missing function, being used to the excellent NXT api ... I could not have imagined that. ETH is still ... work-in-progress, I suppose.)


However, if you know the transaction ID, then of course you can find and see a transaction, how many confirmations it has, etc.

And for each block, all the transactions are now shown too in my version.
    

    

But the EthExplorer can not show the account balance.

Yes.

And when I started I thought: Oh that is easy. ... But in the end, I managed :-)

... to update the EthExplorer ...

It would not be an update, because by now I have changed much too many things.

It would be a completely new thing. Porting my ABEE to your clone.

Please read this whole thread to learn everything about ABEE and ABEESOIL.
TL;DR: What is on the screenshots ... is working.


PM me if you are interested that I port ABEE to your ETH clone.



Enjoy whatever you do

ABEESOIL 0.2.4
AltSheets Block Explorer Extension for SOILcurrency
version 0.2.4 - July 2016

http://178.62.133.174:9001

New in v0.2.4

* address:
  * now also recognized if capital letters in address
  * code comments changed:
     TXs of account would need proprietary backend with all blocks database

* address of contract
  * often code is long, so now table width limited, code is wrapped
  * code length shown
  * code is shown as ASCII too
  * code is disassembled into bytecode, with ASCII conversion of PUSH bytes

* block:
  * timestamp now also shown as UTC time
  * seconds since previous block
  * gasUsed and percent of gasLimit

* transaction:
  * timestamp now also shown as UTC time
  * now also the real gasUsed
  * and correct multiplication to tx price
  * pending tx not showing unused fields anymore
  * if tx has input data, show ASCII converted
  * if tx fired log events, show number of events

* chain
  * better async for the 6 past blocks calls
  * + block time averages for the past 10 blocks


In the following examples & screenshots, I am using the SOIL FAUCET CONTRACT,
see ANN post (there is money in that faucet, by the way). By executing
the command SOILfaucet.getSOIL.sendTransaction({from:"0x..."})
you get 0.5 SOIL sent to you.

Code at contract address
Example here is the SOIL FAUCET CONTRACT.
That contract lives at address 0xdac49860bee0e6d0775f69721459c411d62fd1bc



Note the TransactionCount 0.
In ETH, internal transactions within contracts (here `msg.sender.send(sendAmount)`
inside the `getSOIL()` function) are not registered as transactions of that account.

You can expand the 3 triangles, first to see the code as hex, and ASCII:



And also disassembled into bytecode:



Because PUSH commands sometimes contain readable strings,
for all PUSH commands I am also showing the ASCII representation
of the bytes, behind the // as comments.


Simple address

As example, the donation address for ABEESOIL (please give more, thanks)
at address 0x8da4fc05ca343e6a41646194e91931d9f413a40c



Here, the 4 outgoing transactions are accounted for.

As it is a simple address, not a contract address,
there is no code, and all other fields are suppressed.



Transaction

As example, a recent transaction to that FAUCET CONTRACT
SOILfaucet.getSOIL.sendTransaction({from:"0x..."})
0x0abd2244db18d94db716e3eedbc37ef62e65c64cca86a5f9eeb2960dd3c494f7

PENDING


While the TX was pending, only the provided default gas (90000),
and the offered gas price (50,000,000,000 Wei) can be known.
The `SOILfaucet.getSOIL()`transaction has some data input.

MINED



When the TX is mined, we can know the real gasUsed (48763),
and the transaction fee (48763 * 50gigawei = 0.00243815 SOIL).

The block time is now also shown as UTC time.

That transaction was mined in:


Block

897619



We see the gasUsed (48763), and the percentage of the limit (1.55%).

The block time is now also shown as UTC time,
and additionally, the seconds since the previous block.




Chain, Node, Blockexplorer
By clicking on the 0.2.4 at the top, you get to http://178.62.133.174:9001/#/chain/
with a lot of information. For details see older post about 0.2.3 and post about 0.2.2



Invisible changes: Worked on the asynchroneous past-blocks-queries, to make it faster.
Visible changes: Past 10 blocks.
