--- CPUCOINS DEFINITION

CPUCoins are a virtual credit that can be used only to buy CPU resources in CPUShare.

After a seller starts computing in exchange for CPUCoins, the account will start to get filled with virtual money (i.e. CPUCoins). After gaining the first amount of CPUCoins the seller will be immediately able to buy other CPU resources with the virtual money he gained in his CPUShare account. So the CPUCoins are already useful to the users, in order to use CPUShare as a strict CPU accumulator.

CPUShare will enforce most of the time an huge CPUCoin buy order at a certain price that may vary over time. It is up to the sellers to choose if they accept computing in exchange for CPUCoins or not (CPUCoins must be allowed in the sell order before a seller will start to compute in exchange for CPUCoins).

In the early days the computations executed by the CPUShare system and payed with CPUCoins, will be pure benchmarks to evaluate the power of the Low Cost Supercomputer generated by CPUShare and to tune the system (the statistics will be visible in the cpushare.com website, and they will be hopefully helpful to attract real money into the system so that users will have a chance to sell CPU resources in exchange for real money). Over time the computations executed by CPUShare in exchange for CPUCoins could include the research of Prime Mersenne numbers and hopefully some more useful project. In the very unlikely case that any tangible cash would be generated by the computations that CPUShare has payed to the sellers using the CPUCoins (for example in the very unlikely case that CPUShare would win an award for the research of the Mersenne numbers from http://www.eff.org/), the tangible cash will be fully reinvested by CPUShare entirely in the development of Open Source Software (as defined by the Open Source Initiative at www.opensource.org) that CPUShare will actively oversee.

Like all other buyers, Andrea Arcangeli and cpushare.com are still free to profit from all cash generated by computations paied with Cash (and not with CPUCoins).

CPUCoins are like the credits of a video game and they will worth nothing outside the CPUShare system and they cannot be transferred outside the CPUShare system.

CPUShare reserves the right to enforce anytime real money commissions on CPUCoins orders and to freely increase the CPUCoins denominated commissions on all CPUCoins orders.

If the CPUShare system will financially fail and it will have to be turned off permanently, all the CPUCoins will be deleted (CPUCoins have no value outside the CPUShare system so there will be no refund). CPUShare can start and stop to distribute CPUCoins in any way at any time to anybody, but in order to give more worth to the CPUCoins, CPUShare will try to avoid deleting the CPUCoins logic from the CPUShare system, until all CPUCoins will be consumed as CPUCoins commissions. In order to use the CPUCoins it's still up to the buyer to find sellers that agreed to compute in exchange for CPUCoins in their sell orders (CPUShare has no control on the seller decisions and in turn it has no control on the worth and usefulness of the CPUCoins).

--- CURRENCY FEES AND SERVICES

Creating the account and placing orders at CPUShare is free.

Sellers will never pay anything to Andrea Arcangeli or cpushare.com. Seller costs can only be related to currency conversion or money transfers through PayPal, or increased energy, networking and hardware costs for example related to running the CPUShare global benchmark with the CPUShare software. CPUShare will never charge any fee to the sellers. Sellers can gain CPUCoins or real money in their "wait withdraw" balances by selling their CPU resources.

Only the users entering buy orders will have to pay money to CPUShare if they want to increase their "buy power".

If the buyer disconnects during the transaction CPUShare will transfer the amount from the buyer "buy power" to the seller "wait withdraw" even if the transaction was aborted. If the seller disconnects during the transaction the buyer will not be charged and only the the "buy locked" will be reduced accordingly.

It is the seller responsibility to verify the price he is selling his CPU resources will offset the increased energy costs that the cpu will generate while computing at maximum power instead of being idle, the increased aging of the CPU silicon, and the other energy, networking and hardware costs associated with running the CPUShare software even while not executing any transaction (like the CPUShare global benchmark). It is also the seller and buyer responsibility to verify there are no networking bandwidth costs associated with the traffic generated by the CPUShare client software.

In the first version of the system it will not be possible to be paid for networking bandwidth usage. So only the users with flat rate full time internet connections are allowed to use the CPUShare client software. It is the account owner responsibility to check all his/her networking, energy, and hardware aging costs before considering running the CPUShare client software.

--- MEMBERSHIP ELIGIBILITY

You must be at least 18 years old in order to create your account. If you are 17 years old or younger, you're not allowed to create a CPUShare account. If a CPUShare account owner is found to be less than 18 years old the account will be closed.

It is the account owner responsibility to own the hardware resources, the electric energy and the networking bandwidth that are put on sale using CPUShare. CPUShare has no control on the ownership of the CPU resources/electric energy/networking bandwidth that are offered on sale through the CPUShare system and in turn CPUShare shall not be liable if they're not being sold from their respective owner.

For example one employee has been laid off in the US because he was running seti@home on some server overnight. It was not a seti@home mistake but only the employee mistake, and in turn seti@home was not liable for it. seti@home couldn't even know about it. The same applies to CPUShare.

--- VENUE

CPUShare acts as a venue to allow anyone to sell, and buy CPU resources, at anytime, from anywhere through the Internet. CPUShare has no control over the quality, safety, legality, truth or accuracy of the CPU resources of the sellers, nor on the quality, safety, legality, truth or accuracy of the buyers. CPUShare can only enforce the ability of buyers to pay for the CPU resources that they get from the seller, if there's no error during the transaction. CPUShare cannot ensure that a buyer or seller will actually complete a transaction and CPUShare cannot guarantee that the results of the computations will be correct.

--- IDENTITY VERIFICATION

CPUShare isn't doing identity verification, but if you abuse the service there will be technical automatons that will identify you and your account will be deleted. If your account is being deleted because your computer is malfunctioning you will be given an option to return in compliance after you repair your hardware.

--- DISPUTES

This User Agreement shall be governed by and construed in accordance with the laws of Italy.

If any provision of the terms of this contract is found invalid or unenforceable, that provision will be enforced to the maximum extent, and all the other provisions will remain in force.

--- CPUSHARE PASSWORD

You are responsible for all actions taken with your email address and password, including fees charged to your account. Therefore CPUShare recommends that you don't disclose to any third parties your password. If you choose to share password or your personal information with third parties, you are still responsible for all actions taken with your account. If your password has been compromised for any reason, you should immediately change your password. If you lose your password it can be regenerated after identifying yourself securely.

You are responsible to choose a non trivial "forgot password question" and "forgot password answer", because if somebody gains illegal access to your email account, the lack of answer to the forgot password question is what will prevent your CPUShare account to be compromised too.

You are responsible to check that you're always connected to the www.cpushare.com website before inserting your user and password. If you don't verify the website name accurately, you risk that somebody could steal your user and password with a fraudulent clone of the cpushare website. CPUShare has no control on the fraudulent spam that you may receive at your email address, it's your responsibility to filter out the spam.

--- KEEPING YOUR PERSONAL INFORMATION UPTODATE

It is your responsibility to keep all your personal information and especially you email address, your Country and your private or business status uptodate. Andrea Arcangeli and cpushare.com shall not be liable if you fail to receive an email from CPUShare because you didn't keep your email address uptodate inside your CPUShare account.

You agree that Andrea Arcangeli and cpushare.com shall not be liable if you insert any incorrect personal information that would illegally alter your tax payments.

--- SECURITY

CPUShare protects all data in your accounts with strong encryption of all data and swap space. CPUShare protects the network with firewalling and all sensitive communications with the cpushare.com domain will be encrypted. CPUShare only uses highly secure open source software. The system is designed in such a way that even if the CPUShare servers would be physically stolen nobody should ever be able to gain access to your personal data.

If you find find a way to escape the kernel jail in the seller systems we'd be pleased if you could contact us before disclosing the information to the public using the form in the website. If we're online (most of the time we are) we'll be able to secure the system literally in less than 30 seconds after verifying and agreeing with your security report. CPUShare will eventually setup a prize for anybody who can find a way to escape the jail. This prize will increase over time and it will be specific to a single kernel/client version.

--- ACCOUNT AUTOMATIC DELETION

CPUShare will reserve the right to delete accounts without real money and without CPUCoins that have not been accessed a single time for more than 1 year. Those accounts only wastes server resources and they can be freely regenerated by the user if needed. A warning email will be sent 30 days before deleting the account. Logging into the account within 30 days after receiving the email will be enough to stop the automatic deletion procedure. If the email delivery fails because the email address is not uptodate, the account will be deleted anyway after 30 days.

--- BUY POWER

When you add funds from your PayPal account to the "buy power" balance of your CPUShare account, you receive an invoice for the whole amount transferred and in turn you transfer the ownership of the money to Andrea Arcangeli and cpushare.com. The total amount of the invoice will not include the currency exchange rate. The invoice total will be in EURO and it will show you the total money that entered the CPUShare PayPal account, the vat tax (if you have to pay it), the CPUShare commission fee and the "buy power" that will become immediately visible in the balances of your account. The PayPal fee is also written in the invoice for reference but this is not charged to the buyer and it's a cost for cpushare.com instead. The invoice will be in pdf format and it will be downloadable from your account. You will receive a notification by email to download and print the invoice. If you don't receive the email notification you agree to contact Andrea Arcangeli and cpushare.com immediately. You agree to check the correctness of the invoice within 3 business days after receiving it and to immediately notify Andrea Arcangeli and cpushare.com if there's any problem with it.

--- WAIT WITHDRAW

In order to withdraw the "wait withdraw" balance from your CPUShare account to your PayPal account, you agree to emit a receipt or an invoice respectively if you're a private or business users.

If you're a private user the cpushare.com website will prepare a receipt for you. After you confirm the receipt generation, the cash will be transferred from the CPUShare PayPal account to your PayPal account. Normally the transfer will be immediate, but it may take up to 2 months to be executed. If you notice any significant delay you agree to notify Andrea Arcangeli and cpushare.com immediately. The first time you withdraw, the amount will have to be between 30 and 77 EUR. All later times the amount will have to be exactly 77 EUR.

If instead you're a business user you will have to upload your invoice in pdf format to the cpushare.com website following the guidelines provided you by the withdraw procedure in your CPUShare account. After checking the correctness of the uploaded pdf invoice, Andrea Arcangeli and cpushare.com will proceed to withdraw the "wait withdraw" amount to your PayPal account to complete the transaction, if your pdf invoice was correct. The first time you withdraw by invoicing CPUShare, the amount will have to be at least 30 EUR. All later times the amount will have to be at least 77 EUR. It may take up to 2 months for the invoice payment to be executed. But normally the manual payments should go through within a few days.

The total of the receipt or of the invoice will show the net amount of cash that is leaving the PayPal CPUShare account. What you will get on your PayPal account may be lower and it will depend on the currency exchange rates and on the PayPal fees charged to your PayPal account.

To use CPUShare you must be aware that if you are located in a tax heaven blacklisted by the Italian tax laws at the time of the withdraw payment, Andrea Arcangeli and CPUShare will have to charge you a loss (probably around 50% but subject to change depending on the current financials of the business and depending on the frequently changing Italian tax laws) on your "wait withdraw" before transferring the money to your PayPal account. This is because if you are located in a blacklisted tax heaven, it is apparently not possible to declare those withdraw payments as costs for the CPUShare business. Without this special percentage loss charged to the sellers located in the tax heavens, CPUShare would otherwise risk to go bankrupt by paying more taxes than what it is earning in commissions. The Italian tax laws are changing relatively frequently. Some of the countries that may be included in the blacklist (but this is only an example for your information, and this blacklist may be changing at any time according to the current Italian tax regulations) are: Andorra, Anguilla, Antigua e Barbuda, Antille Olandesi, Aruba, Bahamas, Bahrein, Barbados, Belize, Bermuda, Cipro, Dominica, Gibilterra, Grenada, Guernsey/Sark/Alderney, Isole del Canale, Isola di Man, Isole Cayman, Isole Cook, Isole Marshall, Isole Vergini Britanniche, Isole Vergini Statunitensi, Jersey, Isole del Canale, Liberia, Liechtenstein, Maldive, Malta, Mauritius, Montserrat, Nauru, Niue, Panama, Principato di Monaco, Saint Kitts e Nevis, Saint Lucia, Saint Vincent e Grenadine, Samoa, San Marino, Seychelles, Tonga, Turks e Caicos, Vanuatu.

--- FLOAT

The CPUShare system over time will generate a float of money temporarily owned by Andrea Arcangeli and cpushare.com. The float at any given time is the sum of all "buy power" and "wait withdraw" balances. As long as this float is relatively small it will remain in the PayPal account earning no interest. If this float will grow significantly, you must be aware and agree that Andrea Arcangeli owns the float and is free to move it in a real bank account and to earn interests on it, or capital gains if proper investment opportunity arises in securities traded in the US markets.

--- MODIFICATIONS TO THE USER AGREEMENT

This CPUShare User Agreement contract can be modified by Andrea Arcangeli and cpushare.com at any time without prior notice. After any modification of the CPUShare User Agreement the new version will always be published in a webpage linked by the homepage of the http://www.cpushare.com/ website for 30 days before becoming effective. You will have 30 days to close your account free of charge if you don't agree with the future modifications before they will become effective. It is your responsibility to check the CPUShare User Agreement for any modification to it.
