versions 1.2 to 1.3 looked on my old CPU 1.8 MK / s
For version 1.6 it was already a nice increase in speed, a nice optimization Jean_Luc nice!

Tested Jean_Luc nice, on my old gear the improvement is 65% CPU .... for the GPU I can not enjoy it for the moment CUDA 8.0

I didn't published yet the release as executable downlaod, if you want to test it you have to clone the git repository and compile by yourself.
The new release is coming, I'm currently working on GPU code Wink

Ok actually I was thinking it’s weird too Grin

to 2160/m, the probabilty  ->  probability

the probabilty of finding  -> probability

Thanks Wink
Hope I will be less disturbed by dreamers !

It would be nice (but requires a completely different program --> https://github.com/basil00/pairgen) to exploit the birthday paradox to find 2 addresses with the same very long prefix.

To find 2 private keys (and then 2 public keys) related to the same address, it takes about 2^80 steps. But you can't pick wich address will be.

To find 2 private keys that generate 2 public keys with the same first 100 bits, it takes 2^50 steps.  

https://www.reddit.com/r/Bitcoin/comments/34hjph/generating_partial_address_collisions_using_the/

pairgen as cubitrack are totally different from vanitysearch or vanytigen they have absolutely not the same goal!
Pairgen would actually be the fastest and most efficient program (faster than cubitrack). Using the Birthday Paradox is very effective but it should be optimized much more because currently it only works on CPUs even if it is very fast, make it usable on GPU would give amazing results and optimize its functions like being able to choose an input file -i (several prefixes which one could choose) and a file of exit -o (for each collision found since -i ) and a -continue function or -stop .....
In the current state it is possible to find a prefix of 12 characters without problem see 14 but actually it is not possible to choose the address

ah yes impressive speed but the tesla config is crazy  Shocked ! it also allows to see that despite a software optimizes and the top of the technology it is still not possible to obtain a vanity address of 12 patterns or more in a reasonable delay alas  Undecided
it can already have good fun to create beautiful addresses of vanity if you do not climb so high in the number of pattern remaining within a reasonable time ...

Intéressant tout ceci, blockchain permet 10kE de retrait par cycle de 24h c'est pas trop mal, bon tout dépend des montants souhaité mais au pire entre kraken, blockchain et coinbase il y'a deja de quoi faire en terme de retraits hebdo 😊.
Au final coinbase c'est vrai que c'est tres simple d'utilisation, assez intuitif mais beaucoup trop verrouillé et cher au final. Pas forcément là meilleur des plateformes un tant soit peu qu'il existe une la perfection n'existant pas.
57  Local / Discussions générales et utilisation du Bitcoin / Gros retraits via coinbase on: January 02, 2018, 05:53:10 AM
Bonjour
Voilà mon interrogation est simple mais la réponse est peut être plus complexe. Disons que dans un avenir plus ou moins proche le BTC gravite sur les 30000€ voir 50k ou plus l'unité, disons également que par une chance inouïe j'en possède quelques dizaines acheté aux balbutiements du BTC et que je souhaite en transformer une partie dans le cadre d'un projet immobilier pour concrétiser une partie de ces gains.
Il faudra donc transformer cela en euro car l'achat d'un bien en BTC chez le notaire du coin n'est pas possible (pour le moment). Disons dons je voudrais retirer depuis coinbase 40 BTC au cours actuel cela donne  plus ou moins 420000€, est t il possible d'effectuer le retrait en un seul jet ou pas chez coinbase?
Si la réponse est non quelqu'un a t il tenté de retirer des montants conséquents en une seule fois via son compte bancaire et depuis quel plateforme?
Quel est le meilleur moyen de retirer de gros montants en une seule fois car bon si les sommes en jeux sont importantes attendre 2 ans pour retirer aux comptes goutte ce serait penible d'autant que la volatilité du BTC est assez importante et laisser un paquet d'Euro sur un changeur ce n'est pas terrible.
Y a localbitcoin mais bon faire une transaction de cet ordre au bar du coin avec un inconnu cest bof meme si la bière est bonne , vendre peut etre genre l'ensemble à la maison du BTC est ce possible? Enfin voilà juste par curiosité quelques interrogations si quelqu'un a déjà eu affaire ce type de démarche ou à une expérience personnel sur ce type de transaction, ca m'intéresse.
58  Local / Actualité et News / Re: LITEBITCOIN LBTC Qui connait? on: December 30, 2017, 01:29:17 AM
Bonsoir
LBTC, je connais, j'en ai acheté, j'en détiens quelques milliers.
Pour suivre l'actualité de cette crypto qui est une monnaie ayant pour vocation essentiel le paiement et micro paiement (ultra rapide /sans frais) il y a un groupe Telegram récent dont se trouve le staff dev
Telegram officiel https://t.me/Litebitcoin
Un canal Telegram russe vient d'être également crée.
Le site officiel LBTC cest ici
http://www.lbtc.info
On peut y trouver toutes les infos utiles concernant la crypto ainsi que les divers wallet pour y stocker ses LBTC, actuellement wallet dispo pour Android, Windows et Mac
Il est également possible de la stocker sur paper wallet (ce qui a été mon choix)
Pour acheter la crypto actuellement ce n'est possible que sur cryptopia qui est la seul plateforme à la proposer
https://www.cryptopia.co.nz
Début 2018 d'autres referencement (plateforme) vont arriver les demandes sont en cours et attendent la validation. Un échangeur devrait également arriver dans la foulée ainsi que d'autres News "prometteuses" pour en savoir plus venir sur le canal Telegram poser les questions aux admins et dev qui sont très actifs.
Pour explorateur de block, API, MARKET et diverses infos concernant le minage c'est ici
http://litebitcoins.thecryptochat.net
Attention à ne pas confondre avec lightningBtc ou autre LBTCX qui figure sur Yobit ou tout autre referencement rien qui ne correspond en rien avec LBTC ni à son cours réel .
Sa cotation réel coinmarketcap
https://coinmarketcap.com/currencies/litebitcoin/
En espérant avoir donné un rapide descriptif concernant cette crypto ainsi que quelques infos utiles.
Cette crypto n'est qu'à ses tous débuts  (5 mois à peine) j'ai tenté le paris, un cours de 4000 sato devrait être un strict minimum pour LBTC en 2018 au vu de tout ce qui va arriver la concernant, toute façon  au niveau de cours actuel et au vu de ses perspectives et News le ratio gain/risque est tres  favorable.

yes i still run vanitygen as oclVanitygen from the same folder in which i did the extraction after downloading. In this folder are these 2 files
cacert.pem
calc_addrs.cl
For the file cal_addrs.cl I edited and saved from the link provided above
Here I just update driver and OpenCl library from this link
https://software.intel.com/en-us/articles/opencl-drivers

The intel drivers also support Nvidia cards unless specific extansions are in the code which is not my case.
However nothing changes I exactly the same messages
