It was the Bitcointalk forum that inspired us to create Bitcointalksearch.org - Bitcointalk is an excellent site that should be the default page for anybody dealing in cryptocurrency,
since it is a virtual gold-mine of data. However, our experience and user feedback led us create our site;
Bitcointalk's search is slow, and difficult to get the results you need, because you need to log in first to find anything useful - furthermore, there are rate limiters for their search functionality.
The aim of our project is to create a faster website that yields more results and faster without having to create an account and eliminate the need to log in -
your personal data, therefore, will never be in jeopardy since we are not asking for any of your data and you don't need to provide them to use our site with all of its capabilities.
We created this website with the sole purpose of users being able to search quickly and efficiently in the field of cryptocurrency
so they will have access to the latest and most accurate information and thereby assisting the crypto-community at large.
I don't know whether you can for commercial purposes call these "checks" in the U.S., because they are probably not negotiable instruments under the UCC in the U.S. Not because they are electronic, but because bitcoins are not government-issued currencies and thus not "money" under the UCC. Unfortunately it's still "money transfer" under money laundering laws. Caveat: IANAL, you should consult a lawyer.
I have developed a sample electronic check for bitcoin. This should work for printed checks, as well as for mobile devices. Maybe we could develop this as a standard for http://bcspec.org/. Note that this scheme requires a payment processor as intermediary, to store the checks until they are paid.
Key: "BITCOIN_CHECKV1": specification identifier "u": user identifier at payment processor. Note: unreliable information (rely on 'n'). "n": unique check id number at payment processor. "v": value. Note: unreliable information (rely on 'n').
QRcode is a nice, barcode-friendly, photo-friendly method of passing information. It's very flexible.
However, the concept of electronic checks themselves have a few notable details: * May work with merchants * May work with mobile phones * Like checks, a simple photograph can enable theft. A normal US check includes bank account info, from which a thief may use to steal your money. With bitcoin checks, the thief may only steal money for the amount of the check. * At the option of the payment processor, a password may be required in order to use the check. * Payment processor may provide option to stop payment on a check.
