Bitcoin: the world's new currency--will it eventually dominate?
I have a Raspberry Pi (and keyboard and mouse and monitor) and I want to use it for keeping a copy of my company's database. However, the thumb drive I will be using must become an encrypted drive so that I do not publish personal details of all our service users by mistake. You must install VeraCrypt on a Raspberry Pi model 4. However, if this is not possible, then you can install it on my model 3. I will visit you (you must be within an hour's drive of London) and watch while you get it working and take my machine away. If absolutely necessary I will leave the machine with you for 24 hours. No more.
We'd like to hire a smart contract developer (Polygon network) to review our contract to ensure there are no glaring security holes in it. Furthermore, we want the security professional to review the NFT minting website to ensure it's connected to the smart contract & the organization's wallet properly. The project will start on 12/5. Please include in your quote how many days the review would take.
You have to create 3 scripts that: 1). will create a partial/unsigned transaction to spend from a 2-of-3 multisig address (already with funds) with Bitwasp PHP library. 2) create a script with bitcoinjs-lib that will take the above created tx hex and sign with one private key. 3) create a script with bitcoinjs-lib that will take the above signed tx's hex and sign the transaction with the final priv key in order to be ready to be broadcasted ( as hex ). More technical details in the PDF attached, like private keys and stuff that you can work with. My budget is around $50. If you know what you are doing, it should be very simple since there are plenty of examples with these libraries.

There is a question and answer mechanism. It consists in the fact that the question "Q" is 4 bytes, for eg. 0xAA 0xBB 0xCC 0xDD. The answer "A" is generated in such a way that the sequence "S" with a length of 8 bytes is added to the question "Q". A sequence of 12 bytes is then created. The SHA256 hash function of that 12 byte string is then computed. The first 4 bytes of the calculated SHA256 value are the response "A". So, for example: Q = 0xAA, 0xBB, 0xCC, 0xDD S = 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08 SHA246 (AABBCCDD0102030405060708) = e455df10f57a47498c12c5eaad9b93f525aba1252a7a3a7fee160878db0b6aa8 so: A = e455df10 (first 4 bytes). I know 3 pairs of sample Q questions and A answers. The goal is to calculate S which is a ...
