Wallet – Bitcoin Multisig Contract – to lock coins with nTimeLock (BIP65)

I really need help.
I am currently developing a Bitcoin wallet and would like to implement an SMS-based sending function in which the sender does not need to know the recipient's publicKey. After the contract on the recipient's phone has been made through the wallet, the public key should be added and the redemption process / redemption script executed.

Is that possible somehow?

In a subset of $ mathbb {R} ^ 2 $, which is not simply connected, is there a simple loop that does not contract to a point?

I have previously asked in which topological spaces the existence of a loop, which is not contractible, implies that there is also a non-contractible simple loop?

In view of the broad scope of this question, I propose this special case as a separate question:

In a path-connected subset of $ mathbb {R} ^ 2 $ What is not connected? Is there a simple loop that does not contract to a point?

Cryptohands – from 0.05 ETH. First open MLM based on Ethereum Smart Contract. – MLM & Network Marketing

Crypto Hands


CryptoHands – It's the first open MLM based on Ethereum Smart Contract. The project is transparent and all transactions between participants are visible in the blockchain.

Short description:

Participation in the project costs 0.05 ETH. Then you can win 3 participants for the project, of which you earn 0.05 ETH each, which equals 0.15 ETH in total. Then you can get new referrals for your referral link, and all new members will be listed under your referrals. All new members buy new levels from you and the money goes straight to you.

The chance to win at full PASSIVE!

How it works

Detailed description:

1. You have a wallet with 0.05 ETH and would like to participate in CryptoHands.
2. You transfer this 0.05 Swiss franc to a Smart contract and the Smart contract transfers it to your upline (to the person who invited you) to take you with you
3. Now you are a member of the system and can bring 3 participants, each of them transferring to 0.05 ETH. Already the first transfer carries your costs
4. When inviting referrals, give them your wallet and enter them in the Data field during the transaction. The smart contract will send you this money immediately.
5. After inviting 3 referrals that have registered under you, you can build a structure under your referrals.
6. Any additional 4 or more people who follow your link will be assigned to your referrals and those people will buy more and more for you
7. Even if your 3 recommendations work well and invite new referrals, your income will grow!
8. The system has a purchasing level. You can increase your level in the system (if you want), then you have to buy higher levels at a higher price.
9. The bigger the system becomes and the sooner you enter it, the more you can earn with its growth.


We recommend using the Metamask plugin!

What is the price for this contract?

Hello,

Yesterday I received an offer from a customer that includes the following tasks:

He wants to migrate about 11 websites (some of them are WordPress and other HTML / PHP websites) and several domain name redirects to point to the new host. Remember that the old host is a shared hosting plan.

The new host will have a VPS that I need to create for each site.

I'm used to running WordPress migrations, but not so many websites at the same time. So, how much would you say that such a job costs in Upwork?

Should it be an hourly price contract or a fixed price? What is the average or reasonable time to get such a job done?

Many Thanks

As a customer, I would prefer to know the price in advance.

As a service provider, I also like to list prices in advance – because that's the way I like it as a customer.

If you want to do this job, start with a low price. Which would assure that you get the job. It could also offer it for free – in this way you will practically pay off with your time (and effort) for your own experiences and education.
That way you can see how long it takes and how hard it is for you. Then next time you will know how much you have to charge.

To edit:
Whenever I do something I've never done before, or at least not for a customer, I let the customer know in advance. Literally:
"I've never done that, so I will not charge it because I have no idea how much time and effort it will cost, and of course, like everything else, I'll test and confirm everything correctly."
Think that's fair. If the customer decides to take no risk, that's fine. Better to mess things up while the client trusts in my "knowledge and experience".

Especially for website migration: I would make sure that the old hosting account / setup is not deleted until it is absolutely certain that everything is working properly (websites, emails …). First test personally, then ask the customer to test and confirm.

During the last migration that I did, I offered to pay for the rest of the month hosting with the current ("old") host out of my own pocket (although I have a lot of experience with it) and mine. I think that builds trust and is good in the long run (could be wrong, but I prefer redundancy whenever possible, no matter how "routine" is a task).

Ethereum Blockchain Smart Contract Audit – corner of cryptocurrencies

Ethereum is responsible for the golden age of blockchain applications and the popularity of computer-based protocols. Through the network we can program any kind of digital contract with highly customizable features. Our team of experienced developers performs Ethereum Smart Contract Audits. Blockchain App Factory performs a thorough review of the contract architecture and code base, highlighting the changes that are required for 100% security. Vulnerabilities in code can cost billions of lost capital to blockchain companies. Therefore, it is time to take the protection of distributed books seriously. A blockchain security check can validate your system and identify sources of error and weak cryptography. With their penetration test, they simulate real hacking attacks to find and fix the vulnerabilities of the ecosystem.

Interface – C # – How do I create an implementation contract with subclasses to implement?

I want to create an interface (I called InterfaceX)

interfaceX
{
...
}

Where would its future implementation return the following structure:

ClassInterfaceX.ClassA.All ClassA method (parameter);
ClassInterfaceX.ClassA.Metodo2 of ClassClass (parameter);
ClassInterfaceX.ClasseB.Class method 1 (parameter);
...

That is, the result would be a class with two nested classes.
However, ClassA and ClassB class methods must also be implemented.

Is there a way to create an interface that forces me to implement subclass methods in C #?
