Bitcoin Forum

This is a complete rewrite of my old script: Eckmar's Marketplace Script (https://bitcointalk.org/index.php?topic=1879294). The two share some similarities (functional), but new version is written from scratch, meaning no code is shared between them.

About script

Marketplace v2.0 is also written in PHP with Laravel framework. Its using latest standards for encryption (like Sodium library) and security. Its made without use of JavaScript, so its optimized for TOR, but can also be ran normally like any other web app (as you can see on demo).

Requirements

• VPS with at least 2GB of RAM
• Daemon for each coin that is enabled on marketplace

Server requirements: (what software is needed on VPS)

• PHP 7 (recommended and tested on 7.2)
• SQL Database (MySQL,PostgreSQL, SQLite, SQL Server)
• Elasticsearch (Search interface that will keep track of search records and provide great search performance)
• Redis (Optional, but will greatly increase app performance )

Features

Categories
Category system is very dynamic. Categories can be nested indefinitely. Creating, deleting and editing of categories is handled in admin panel.

Detailed home page
There is placeholder text on the home page at the moment that will represent most important features of your marketplace.
On top of that, all users can see Top Vendors (Vendors with most sales), Latest Orders (Products of orders completed most recently, as well as order value, but no information about buyer or seller), Rising Vendors (Vendors with most sales in specified time frame, defaults to 7 days).
Official mirrors is place where you can specify on what other links your website can be reached.

Password reset
Password can be reseted with PGP Key added on account (more about PGP below) or with Mnemonic key provided during signup. Mnemonic key is shown only once and should be written down on paper. During signup it is hashed (bcrypt) instantly and only stored in operating memory for the short time during display after which is cleared from memory manually as addition to automatic PHP Garbage Collection.

PGP
Each user can add their on PGP key which is used for multiple features. Vendors must have PGP and 2FA enabled before they are allowed to upgrade from user to vendor status. If you have active PGP key you can reset your password with it or enable 2FA for your login. Each PGP key must be confirmed before is linked to account, and if you want to add new key you must first sign a message from the old one.
Messages can also be encrypted with user's PGP key if its present (this is not enforced, its user's choice).

2FA (Two-Factor Authentication)

If user has PGP key linked to their account, they can enable 2FA. If enabled, login to marketplace will be prevented unless randomly generated message is signed from the key.

Wishlist

Buyers do not need to save product links for later. On each product there is "Add to wishlist" button that can be used, and they are stored in user's personal list for later.

Vendors

Normal users cannot post products on Marketplace. In order to post products you must become vendor. Before you can upgrade you must have PGP key and 2FA Enabled in your profile. Vendor price can be set in marketplace config. Vendor can use any of the coins available to purchase vendor status. Out of each vendor sale, a percentage of sale value goes to marketplace addresses.

Vendor profile customization

Vendors are able to customize their profile with pre-defined profile backgrounds and short personal description.

Vendor levels and XP

Each new vendor starts at Level 0 and progresses further based on performance. XP and Amount of levels is dynamic and configurable. Multipliers determine how much XP is granted to/taken from vendors for each action. XP is granted/taken by formula: USDvalue*multiplier
Example:
     product_delivered multiplier is 20
     USD value of product is 100$
     When vendor successfully delivers product, he will receive 100*20=2000 XP
     This is example from experience config file:

Feedback

After each completed purchase, vendors are able to leave feedback. Feedback types are Positive, Neutral and Negative and they will affect vendor score as well as product score.

Multiple Coins

Probably the most important system is Coin System. Its completely dynamic, which means new coins can be added at any time. Standard version of marketplace comes with Bitcoin and Monero included. For each coin added, in marketplace config there can be set unlimited amount of marketplace addresses (used for receiving fees from purchases), and in case more than one address is present, address for receiving fee will be choosen randomly (for each purchase).

Product types
There are two product types. Physical and Digital products. Based on the type, different options are displayed during product creating and purchase.
Both Digital and Physical products support offers and custom units of measure (Item, kg, gram, piece ...). With offers, vendors can give discounts on purchase based on quantity. For example:
Price for 1 product is 100$
Price for 10 products is 90$
Price for 20+ products is 80$
Each of those is considered an offer and can be added/removed at any time.

Digital products support automatic delivery which is optional. If checked, autofill system is used. Each line in textarea is treated as single item and will be product's quantity. It will be instantly sent on user upon purchase.

Physical products have delivery options. Each delivery option consists of: Name, Price, Expected delivery duration, Minimum quantity for delivery, Maximum Quantity for delivery. Physical products can also include/exclude countries from shipping.

Markdown styling
Instead of just plain text, product description and rules support markdown styling. Every tag is supported except URL tag.

Purchasing

When user chooses to purchase any product, he is able to pay with any coin supported by market (and vendor, since vendors can choose which coins they want on each product). There is no wallets or anything similar. Users do not need to keep money on marketplace at all times. For each purchase random address is generated, and its used for that purchase only.

Escrow

Escrow is present on every purchase by default. Upon purchase, marketplace address is generated that will hold funds. If purchase is completed if its marked as delivered or dispute is resolved. If buyer is unhappy with purchase he can open dispute and potentially (based on admin's decision) get his money back. Upon purchase completion, based on result money will be sent from temporary purchase address to buyer/vendor and to one of the marketplace holding addresses.

Cart

If user wants to buy more than one product (maybe from different sellers too), they can add them all in a cart and then checkout only once.

Messages

Most important feature of messages is security. Marketplace uses latest algorithms and standards in Public Key Cryptography (like XChaCha20-Poly1305-IETF) to encrypt messages between users. Upon registration, Public and Private keys are created for each user. Based on user's password an encryption key is derived, and that key is used to encrypt Private key, while Public Key is exposed. When user A whats to send message to user B, a key exchange happens. User A encrypts message with User B's public key, and that message is stored in database. Only user B can read that message when he logs in and decrypts his messages with password. This system makes messages secure and unreadable by anyone, including marketplace administrator or basically anyone who can possibly get access to the database.

Messages are organized in conversations. Multiple conversations can be started at the same time.

Notifications

Users will get notifications for most actions that happen on marketplace regarding them. Some of the examples are: New message, Purchase status update (product sent, product delivered etc.), Vendor actions (Feedback) and so on.
They can be read in User Account Panel and deleted at any time.

Bitmessage

Marketplace can possibly connect to Bitmessage daemon. If connected, users can chose to add their Bitmessage addresses and get their notifications forwarded there. This means they will still get notifications even if they are not currently logged in, and they don't need to refresh anything.
Before being able to forward notifications, Bitmessage addresses must be confirmed first.

JavaScript Warning

Optional warning can be enabled in marketplace config. If visitor has JavaScript enabled, a message will be displayed notifying them about security issues.

Support

Users can open support tickets regarding any problem they encounter. Administrators/Moderators will see this tickets in admin panel and can reply, or close them.

Admin Panel

Most of the stuff happening on marketplace can be viewed directly on admin panel. Administrators can access every feature on admin panel.

Moderators
Modular permission system is currently supported, which means admins can give/take some access to moderators (For example, support staff can only answer tickets and resolve disputes, community manager can only send mass messages etc.). Currently supported features:

• Index - Basic information
• Categories - Add/Edit/Remove Categories
• Mass Messages - Ability to send messages to users by marketplace (Can be filtered to user groups)
• Users - View users, search, filter, and edit each user individually.
• Products - View, search, filter by user, or edit product
• Log - Activity log of all Administrators/Moderators inside Admin Panel Example:

• Bitmessage - Status of Bitmessage service (performs test), and view of marketplace bitmessage address
• Disputes - View and resolve purchase disputes
• Tickets - View and resolve support tickets
• Purchases - List of all purchases
• Vendor Purchases - List of vendor purchases

Supported coins

Marketplace currently supports these coins:

• Bitcoin - Included in standard version
• Monero - Included in standard version
• Litecoin
• DASH
• PIVX
• Verge
• Bitcoin Cash

Hi can i get a vouch or discounted copy?

Hello,
I'm not sure why would you be entitled to one as you are brand new here with no reputation and single post ? Vouch copies are for reputable members to leave their review so others can see product is working fine and its done before any sales. I've already sold this item multiple times so I don't feel like I have to do that in order to help my sales.

Hi There! Does it support ERC-20 tokens?

Also, could I have a vouch copy? I will set up a server and extensively test your script and give a honest review of it.

Hello,
It doesn't support ERC-20 Tokens at the moment, but if there is a demand for that payment system it can be added in the future.

As for the vouch copy, my quote from the post before:

yes, i bought 2 old market script from him
- btc version
- xmr version

Eckmar is a good developer, honest worker

Thanks for the feedback :)

Scam and swindler!

You registered on forum just to post this based on what exactly?

A lot of memebers ask for discounts or free copies and think they are entitled to them. This is probably one of the rejected ones. Nothing against those guys, but don't be butthurt when you don't get what you want for free, you have to pay the full price.

I bought V1 of this and can confirm he's a good seller.

Thanks for the feedback, appreciate it !  ;D

Everyone who bought v1 of the script have 100$ discount on v2 if the terms are met.

I like this! would i be going insane or don't i see a actual demo? cheers. (got locked out my old account, don't be alarmed lol)

EDIT: I used my eyes and found it, sorry lol

By any chance do you have a demo running on an onion link so I can see how fast it loads over tor?

Tor link is currently not available due to upgrade from hidden service v2 to v3.

Anyway, app is made with best practices including caching etc so biggest impact on performance will be server specifications.

Whats wrong with you pm-ing me? Sent you msg anyway.

you have admin panel demo link? how you integrate the payment gateway ? thru api like coinbase,blockchain or what?

Visit the demo, create new account then visit demo page and give yourself administrator. Payment is made using bitcoin deamon directly.

Kudos

i need a guy to upload my script to a VPS if u can done that DM me on ICQ:MrRobot

I'm interested in this script. Are there any limitations for upgrading? Does it come with a license key? Like, if I buy it, I dont want something that has features locked behind license keys that you can revoke at will. I'd want the script in its entirety and the ability to change whatever I want when I want.

Source is not encrypted, and the script doesn't come with licence key. After purchase you can modify it freely.

Sounds interesting.

hello I would like to buy your script but impossible to mp you

Hi, looks like your account is brand new, so you have a limit on number of messages you can send in a short period of time. You can contact me on telegram @eckmar

guys, if want support for install version 1 of eckmar script i can help you

eckmar know me and i know eckmar, i do a good job (i've installed 1 in 2020, 2 in 2019, etc)

this because eckmar is fully busy and cant do support for v1


thank you all

You're welcome


Yeah, if anyone needs help with v1 installation (older version), message him, he'll help you out  ;D

I sent you a private message here and a xmpp message

Please add Wickr as a contact method. I was unable to install Telegram in whonix.

I purchase this Script many days ago, works fine but have some code bugs and tutorial is not the best always u need a third party support to install, but the support by @eckmar is the worst this guy just say "I don't, I can't I don't have"
Script experience is good by vendor support is terrible.

If you find any bugs in code, please report them and they will be resolved. I think you confuse code bugs with server issues. Its true I don't help with installation, I also make that pretty clear in my thread. If you don't have knowledge to install it yourself, they by all means pay someone to do it for you. Your inability to understand or install the product has nothing to do with me. Next time, learn to read and study the terms of service before purchasing something, it may come long way  ;D

Thanks for purchase, and have a good day.

Had a quick talk with the seller of this product, and i am actually surprised at the level of support and help he provided, so i felt the need to post this to let others who might be on-the-fence about this script, I DOUBT youll have any problems

I had a good amount of questions about the product, early in the morning too. But, i got an almost immediate response (dont expect this to be the norm, i may have just caught him during a good time). Every question was met by Eckmar with a VERY short, but straight to the point, answer.

I havent bought the product yet, but am planning to by this week's end. But, what definitely sealed the deal was his the way he handles his potential buyers :)

Good, friendly guy.  :D

for a very modest fee I will install and configure the script
telegram: @ebaymx

but why should any one trust you ??  :-\

I don't think any sane person would even consider this. Guys don't let random person access your server and install stuff for you. He can do whatever he want with the server and it may lead to a loss of funds.
This is pretty obvious scam attempt.

Please remove this posts from my thread, or I'll have to report them.

but why do you write like that?
The complaint is specifically about you that you do not support your product.
I try to help you and I see that here you can provide my services.
and you can change all the passwords after the end and setup, I do not see anything complicated in this.

I write like that for multiple reasons:

• 1) I don't trust you
• 2) You just registered on the forum, and your first post is that?
• 3) If you knew anything about server administration, you know that after someone has access to your server, changing password doesn't mean much

So please, don't post here again, or remove your posts if you can.

Your scam attempt is quite obvious.

also to add this guy can easily just steal the script for free from whoever pays him to setup or install it;even if he does the job right he will have full access to the files and script and the owner wouldn't even know

I wanted to buy this script but now I doubt it.
Where can I read customer reviews?
someone used the script for more than six months?
is there tech support? and then judging by the first version, those who bought it a new version did not receive but bought again. Will it be the same with this version?
You wrote about theft here. how can I be sure that the script will not steal my money in half a year or when the turnover reaches a certain amount?
it is strange that you do not allow third parties to the script. maybe they will find something there?
this is not a program for entertainment, it's all the same working with money on a dark network.
and the most important question: this script does not knock on the police? if there are no reviews from old customers, maybe there are no customers anymore?

As I mentioned many times in this thread, I offer support for bug fixes, and any other errors caused by me in the first place. I don't help with installation, if you are unable to do that yourself, do me and you a favor and don't buy this.

Marketplace v2 is a completely new script, anyone who bough v1 would receive a discount on v2. If v3 comes out same thing will happen.

If you mean last few posts, I'm not confident that a russian guy with 0 understanding of english and google translate who never saw my script can do anything to help my customers.

Code is not encrypted in any way, if you don't trust me, you are welcome to purchase the code and pay another programmer to check it out.

As for the customers, those who decided to leave their reviews you can find here and on my last thread. I can't comment on any projects using this script.

Thanks for showing interest, let me know if you are bothered by anything else.

I am worried that only your script is concerned about you and not its installation and further work.
it’s your business to sell, and I understand that. but work with him to us. You are responsible only for the script and not for the store that runs on it. and it really bothers. and you write here that I first need to pay you and then also the programmer. But should he also speak English?
What should I do if the database crashes? Why don't you support customers? can any of the clients give feedback?

I didn't say you have to do anything. You said you have some trust issues, if thats true by all means pay someone you do trust to check the code for you, if you don't want to do that no one is really forcing you.

I'm not selling a business, I'm selling a script, a code.
You are correct, after the sale I'm only interested in code. If your database crashes, or you have server issues it has nothing to do with me or my script. You figure it out yourself, or pay someone to do it for you. Thats how it works, I'm not a system administrator for your project after you purchase the code from me, I'm sorry if you don't like that then don't purchase.

I hope I understood you correctly, since it does appear we have some language issues. I would ask you to please read my post again before replying, do some google searches, see how the world works etc.

(Also based on broken english, google translate, same issues and new account I think packtor=404city so please don't spam my thread, no one is interested in your services)

Dear seller, I ask normal questions about the product.
can someone confirm the operation of your script? not a purchase but a job.
I don’t understand what you are writing about and what does the English language have to do with it.
I as a buyer have the right to ask about the product. I have doubts about your account and about the script.
you are blaming many for fraud and theft. and you act like a con man. and if you continue to behave this way, I will transmit all your false messages to the forum administration.
please answer on the product and do not deviate from the topic.
thank.

You are creating another account to ask me questions in order for someone to contact your last account for support? I would say thats a fraudulent behaviour. English language is important, since I don't really understand half of the stuff you say or what are you asking me exactly because Google Translate isn't good enough for conversation level translation (imho)

I indulged your behaviour long enough. I wont't be answering your questions (because honestly I have no idea what are you asking me lol).

I blamed your last account for potential fraud and potential theft (you forgot to switch them buddy, you are making a post from new one now) because thats what it looks like, and your last few posts confirmed that.

You are welcome to report this and my "false mesasges" lol

Dear seller, please answer the questions regarding the sale of the script that I asked earlier.
I made myself clear?
please write me what question you did not understand
I ask questions that concern the sale of the script and you answer something that is not clear.
Why is it so difficult for you to answer questions that relate to this particular topic?
you always shy away from the answer with different tricks
why?

if anyone needs help (especially with version 1 who has support problems) i am your man

trying to swindle or extort or bribe me is useless, I am in close contact with eckmar

some one try to scam me/eckmar (without buy script from eckmar) this not work, i'll contact for every purchaser eckmar

thats all - i'm professional, fast and seriuos one (not cheaper) i have 360 grade solution for all

Hello
What are you writing about now? What does 1 version have to do with it?
Write in the appropriate branch (it still exists) I am very happy for you and your work, but I'm trying to find reviews for more than a year of sale.
The first ad was created on March 25, 2019. Has anyone really bought one since then? Or bought but can not write a review?
I am very confused by the seller’s sarcasm regarding not knowing English. I know that you are not interested in clients from countries where the FBI cannot make an arrest. Or another reason? :))
Once again I ask: are there people who bought the script and have been working for more than 3 months? (Version 2)
Any feedback on the script? Not buying and installing, namely working.

Hi, there are many customers who bought it and used it more than 3 months. If someone doesn't leave feedback, I don't force it. So what you see on this thread is what you get. If that's not enough sorry, don't purchase then.

I'm not sure why are you spamming this thread with your "questions" ? What do you want to achieve? If you want, you can purchase my product, if you don't, its fine. I don't really care what you do.


If anyone needs help with installation, message him

Sorry, but these are just your words.
I see only the description of the script and not the script itself, which is why I demand feedback from customers who have worked with the script for more than 3 months.
I want to learn about the WORK script, I have the right to do so.


Before buying, I want to find out how the script works.
not how to buy. not how to install. And how it works.
Does it work at all? Is it safe for the buyer and then the owner? Does the script send logs to the police? Is the Bitcoin script stealing? Who can answer these questions besides you? Who can confirm at least something?


If I remember correctly, then the person installs only the first version.
Why do you recommend it in the second version of your product?

of course i can install v2 too
i recommend v2 because it work perfect and dont need update/manual job

v1 is obsolete and with less features

only for this reason

They are just my words. I will not force my customers to leave feeedback so you can read it, sorry. If thats not good enough for you, I don't really care.



I told you this before, so let me repeat it again, maybe it was hard for google translate to understand before or whatever.
So you can:

• 1) Trust me that it works fine
• 2) Check it yourself if you know how (code is not encrypted)
• 3) If you are unable to check it yourself, you can pay someone you trust to check it for you (code is not encrypted)
• 4) Do not buy it, and be done with it. Spend your time thinking about something else

He installs v2 as well, so I do recommend him.

Now, I really hope you can translate this, when I put it in google translate, it seems to do the job fine, but idk. I told you all of this in my previous posts. So before asking any new questions (that you already asked once), please read this post again, and the posts before it. Thanks.

Is this your attitude towards customers? That is, no one can confirm how the script works after 3-6 months?


You offered to buy me to check it without money back guarantees, which is nonsense in trade relations.
And again you will not care :)



Good. How do I check the goods before buying? What guarantees do I have that you are not a liar? Indeed, apart from you and your friend, no one can confirm this. Are your customers arrested? Please answer.

You are not a customer. You never intended to buy my product. You are here just spamming this thread because I accused your other account of potential scam




Since I already answered all of this, and you are either stupid or you honestly don't understand what I'm saying , from now on, I'll quote myself, so you can either understand that or ignore it, and you're right I don't care:

Answers to your questions:

I am not a client. Because he changed his mind about buying your product. Everything is very suspicious and does not inspire confidence.
You have been selling scripts since 2017, and no one can confirm how the script works. This is more than suspicious. I'm trying to warn other people.
The script works perfectly !!! but to the police :))
For 3 years of your activity, no one can endure anything.
All this is strange.

Hello
I have been watching the topic for several days.
I didn’t understand. Are there any feedback from users about the operation of the script or not?

Nice, so you a random russian guy tries to ruin my thread and then sends me stuff on telegram:


And for those who do not understand Russan (including me), this is translated version:


So yeah, fuck you mate, your scam attempt failed. And just so someone doesn't say I took anything out of context, this is the full conversation and explanation: https://bitcointalk.org/index.php?topic=5261047.0

Bump !
Still available for sale. If you have any questions, contact me

Babo i sent you pm

Please.contact.me on Telegram or wickr

I have v2 am eckmar client

It's a good instructional, but without the needed files, I can't use it for anything. I got everything (I thought) for $599 and now it says I am missing files :(

So I will go ahead and say 1/5 stars as I do not have what I need to get things going, and I paid for nothing :(

Was working up until we got to the files in the directory

 sudo chown -R www-data:www-data /var/www/DIRECTORY_NAME/public sudo chmod 755 /var/www sudo chmod -R 755 /var/www/DIRECTORY_NAME/bootstrap/cache sudo chmod -R 755 /var/www/DIRECTORY_NAME/storage
Run:
php artisan storage:link
To link public directory with storage.Make this folder: (for product pictures)
sudo mkdir /var/www/DIRECTORY_NAME/storage/public/products
And give it permissions

Soon as we get here, problems occur, and won't work :(

WHERE ARE THE FILES? I have no link to download files, just install instructions.

Yeah, where do I get the files for the install? I have the guide, but no files? Account is locked for some reason, and now I only have saved files from when I buy. User was Sided*** and now I cannot access messages to get my files, but I don't think there were any.

***ALSO HE WILL SAY TO INSTALL JAVA BUT YOU CANNOT INSTALL JAVA IN THAT METHOD*** THEY DO NOT ALLOW INSTALL OF JAVA INSTALL IN THAT WAY AT ALLL SO SCRIPT IS BROKENNNN*** If you are not familiar with Linux and how to install from different sources then you will have to know what to do when it says E: NO INSTALL CANDIDATE

****sudo apt install oracle-java8-installer
 
To see if Java is installed correctly run:
 
sudo update-alternatives --config java
 
Exit out of the command. You should see the path similar to this:
/usr/lib/jvm/java-8-oracle/jre/bin/java
now we need to use that path and create environment variable****

This cannot be done, try it on your own VPS and watch, you will get an error because Java does not allow install like this since 2018, so this is old.

This is correct way, but he doesn't update:

https://i.postimg.cc/FNHrKDJY/Screen-Shot-2020-09-26-at-12-39-24-AM.png

Where are the files?

Anyone who wants to see script can see here:

https://pastebin.pl/view/422aae0d

There are no files though. I buy, and then my account gets locked (I never used before that purchase, and never use again, I come back after 2 weeks, account locked, and all I have is copy of text, but no links to files, so no way to install. $600 gone. WOW. And then a bunch of account saying WOW GREAT! but there's no demos, nothing to show working site, even though nothing on

If you don't have access to files, you can either message me from account that bought the script or provide me with a txid and signed message from address that sent funds. If you are unable to do that, and are messaging me randomly sorry, you won't get any files.

If you feel scammed, you're welcome to open a thread here (https://bitcointalk.org/index.php?board=83.0)

As for Java, its no longer required as it comes bundled with Elastic.


Edit:
I don't understand, you said you bought the script, but you messaged me today(2 days later) saying

hello there - if anyone need.. i'm official Eckmar support mate for help you to install v1 and v2 too
free feel to contact me if need help or advice

see my trusts for understand i'm good in my job and serious boy

Does that multi coin module support multisig bitcoin and other coins such as zcash? If not, what can be done to add multisig transactions? Do you also help buyers migrate to newer Laravel versions? I'd be very greateful if you answer my questions :)

Hi,
Multi Currency module has nothing to do with coins. Its for multiple fiat currencies (usd to eur, gbp...). Multisig transactions are currently not supported. As for implementing it, or migrating to newer versions, you can message me on telegram/xmpp.

After buying the script, how much money will it cost approx to keep it running? I'm thinking of costs for hosting and domain etc?

It depends on the traffic you have. You can start as low as 5$ a month and go from there. Most .com domains go for 10$/y

I am looking for a skilled developer who can install the https://bitcointalk.org/index.php?topic=5124640.0script  and configure it for me.
I can offer payment in bitcoin also if it goes well more projects will be guaranteed.

Pre-requisites:
-PHP (Laravel) knowledge
-Bitcoind knowledge
-Linux vps setup knowledge

Examples of previous projects required
Picures:

You can message me on Telegram
@cyclonetech

Have you tried contacting Babo? Eckmar seems to recommend him and he has good trust on here.
