Hi

Thanks to a personal email to a developper because after 20-30 mintes of lurcking around and see neither a repüly nor a new-topic button, his reply-email
 pointed me to the fact/politics of this newbie posting restriction.
THIS should be made clearly for each new registered account and then also be indicated which boards (or topics) are newbie postable, IMHO!

Here is my posting/proposal to reason my request -- sorry for the bad style. :-/



Hi

The annoying huge real time to build up the blkindex.dat with the bitcoin-client is the trigger why I finally wrote this posting.
Sadly nowhere is explained neither which exact structure blkindex.dat has, nor
why we need this Berkley-DB-B-tree structure at all and it is extremly slow in
rebuild/updating in our case of bitcoin client.
Indeed I needed more than 23 h to build it from scratch with my 2 GHz Athlon-64 and 4 GB Ram. :-( and almost always the real time is spent by wait-for IO, not
CPU or network-band with limited if you want to catch up to the current blockchain.
Looking at the new bitcoin-client 0.7.99 test-release it looks still similar
slow, see benchmarks at [https://bitcointalk.org/index.php?topic=129861.0].
Thus I totaly agree in "We need to stabilize 0.8 as quickly as is reasonably possible, because people are beginning to avoid 0.7.x due to slowness, choosing instead less secure but faster bitcoin clients." stated by jgarzik in this thread.

I wonder why we need all this overhead-full and version-depending DB-stuff for
using/manipulating the blockchain in the bitcoin client. :-/

Here is an alternative for "blkindex.dat":

Hold the blockchain-indexing data always in memory and organize, it as follows:
Let there be TA-many transactions and DEP-many deposits (response-scripts/out-channels) in all the (valid) blocks in the blockchain.

On 2012-12-27 11:45 UTC we had #blocks= 213849, #TA =  10388275, #DEP = 24173524

The needed data structure consists of 2 tables and 1 heap:

1) A hashtable: we have TA many transactions and this number is steadily growing.
It is not decisive but I choose a hashtable which can store up to 2^26 many
 entries (so current fill-factor is < 1/6). Each transaction gets a 4 byte index, e.g.
made up of the lowest 4 bytes of a transaction-hash (or made by xoring the 32 bytes into 4
bytes) anded with 2^26-1 , ==> this is a 2^28 byte sized table, which each entry is either 0 or
indexs a further table, called transaction table for simplicity.

2) The transaction table has #TA*(32+2+8) bytes = #TA*42 bytes.
   Each entry of this transaction table holds ITS 256 bit doubled SHA-hashed hash = 32 bytes (back-check to the hashtable for index-collision-detection), a 2 byte counter (could be also 4 byte) for number of deposits and an 8-byte pointer into a heap for a specific transaction of a block of the blockchain.

3) the heap of deposit addresses and deposit values has size #DEP*(2*8+8) bytes
   Here the explicit value in Satoshis, the address of the script, and the
   address of the redeemed script is stored (null address if the deposit is
  still availible).
  The value of the deposits are pure luxury and could be saved. This value could
  also be goten from the address of the script decreased by 8. But I liked to
  store this value explicitly (in 8 bytes) and not looked it up each time in the
  blockchain.

The size of these 3 structures sum up to about 1285 Mbytes compared to 1481 Mbytes of the current blkindex.dat. The heap and the transaction table grows simply
by appending new data if new blocks are mined and published.
Searching for a transaction given by its 256-bit hashindex happens in constant time (depends only on the fill-factor of the hashtable) -- in contrast any B-tree needs log_2(#TA). Adding a new transaction with its deposits is of course proportional to the number of deposits involved.

Thus the real time needed to access a deposit is constant. There are the rare
events when we want to delete a orphan block and thus removing transactions with their deposits from our data structure. In this case, the needed real time is
at most proportional to the age of the orphan block respectively number of blocks in the part of the forked chain measured in number of deposits containing in the end part of the forked chain.
The average real-time behavior should be at least as fast as the old
"blkindex.dat"-logic, but probably much faster because we need no log_2-searching factor from the B-trees involved.

I implemented this logic/data structure already as part of a blockchain parser
and a total build up of this new "block-index structure" needed 242 sec real
time and 71 sec CPU-time - most time was spend in reading the blockchain from
disc. BTW: I did not optimize the source-code, already the 2nd program version
needs only these 4 minutes. I recall: Compared to more than 23 hours real time of the
bitcoin-client 0.7.1 needed to rebuild the blkindex.dat via "-loadblock" options. :-(

So the only draw back I currently see is a need of 1.28 GB Ram compared to at most 1/5-th (or less?) Ram in the bitcoin-client + 1.5 GB of blkindex.dat disc-space.
Omitting the Satoshi value of each deposit in the data structure and using only
a 2^25 sized hashtable (currently means a factor of 3.23 of total to used entries)
would result in 0.96 (0.13+0.44+0.39) GB Ram. Of course this data structure could be stored also on disk to avoid rebuilding each time the client starts.

The win is a real-time factor decrease of 350 -- and in absolute units from
many, many hours to a few minutes when building up the index data from scratch
in a bitcoin-client or whatever.  :-)

I like to hear your thoughts/critics.

BTW: If this is not too much nonsense perhaps a member could make a pointer to this posting in the thread/topic "Experimental pre-0.8 builds for testing" in the "Development & Technical Discussion"-board which is forbidden for newbies like me.

Thanks,
smtp

I'd like out, been mining bitcoins since before D-Day (Drop Day from 50btc reward to 25btc reward) on our boy slush's mining pool.  I don't know how the whole infrastructure works for bitcoins, other than it's p2p encrypted virtual currency; still haven't googled why there are typically 8 servers my btc client connects to but meh. 

I can spout a bunch of googled technobable from the bitcoin wiki in here or you can just take me out of newbie land. Actually this may be my fourth post so maybe I met the criteria already Smiley

Anyway, awkward!

Thanks for your time.

Hello,

I want to be whitelisted because i've already minned bitcoins and namecoins, i know how to use the bitcoin and namecoin clients and the guiminer and poclbm miners.
I m not interested in post on the newbie forum because I cant learn anything else as a newbie and i cant post on the spanish forum as a newbie.

Hey,

we're a group of researchers currently looking into Bitcoin from two angles: technologically, and economically (researchers as in University-level research).

We have been reading in this forum for 1-2 months now, and are well past the newbie state. We'd like to have full access so that we can ask specific questions in the appropriate sub-forums.

Thank you,
Arnuschky

Hello!

I've been a bitcoin user for a little while now, but I've only lurked on the forums, without an account.

I've been having a problem with campbx.com and I found a relevant thread I'd like to post in about it. This is that thread: https://bitcointalk.org/index.php?topic=133738.0

I don't really have anything to post about in the newbie area, the 5 post minimum seems to encourage spam. If I could be whitelisted, that would be great!

Thanks

i have been using bitcoin for 8 months. I have spread the bitcoin idea to many people in real life. I mostly use them for poker/casino stuff. i first came to bitcointalk.org to see why my wallet was loading so slow. that was one of many visits i made for information.I am working on a project that i believe will continue the growth of users in the bitcoin community.
i was hoping to create some buzz on this site, as well

thanks

Get me out'a here!

Although I have only just started mining, I have known about bitcoin for quite some time.

I have services to sell.

I plan to sell lessons and private lessons in network security and wireless penetration. WEP/WPA/WPA2 Keys were secure yesterday, not today.

Beginner to Intermediate lessons.
After my overseas holiday I will be opening up advanced lessons.

I will be using bitcoin only as payments for the online lessons.

Lessons will take place in my own private freenode rooms. -SSL is advised.

All legal I can guarantee. I will also be teaching the laws associated with network securi

My name is Pezikrypt, and I am requesting my name to be put on the Whitelist. I don't want to be stuck in the Newbie section for very long.

I've introduced myself here - https://bitcointalk.org/index.php?topic=133986.0

Carried a conversation with 3 other individuals regarding BitCoin and rigs. We came to the conclusion that I need to invest in a ASIC device to continue mining when they are actually released (they being the ASIC devices).

I've also wrote a review over SwiftBitcoins, whose thread can be found here - https://bitcointalk.org/index.php?topic=134013.0

I pointed out his thread's link was incorrect, and we got it fixed. I also tried his service, and it was nice. Could be nicer, but my review it posted on the first page, just have to scroll down a little bit.

Anything else about myself can be found in my thread [Newbie] Mining for BTCitcoin.

I would like to make input to the custom FPGA mining discussions, I am considering making a massively parallel fpga stack.

I have only just joined this forum, but I have been on other bitcoin forums, and have been using bitcoin for 2 years now. mined in pools for a bit, sold some on ebay.

I understand the maths behind bitcoin fairly well, and will provide interesting input to the fpga threads.

Dear Bitcoin Forum,

I think I'm ready to interact with the rest of the Bitcoin Forum beyond the Newbie area. I've been researching Bitcoin for several months nows and I promise not to ask beginner type questions. I've also got a good handle on the community terminology and best practices.

Thanks. I look forward to getting more deeply involved as a merchant planning to accept Bitcoin startin in March.

Best Regards,

-DJohnston
