Hello guys,
It is possible, on a computer with 2 hard drives, to use and update the same blockchain using Bitcoin Core?
The first HDD is a dual boot Windows 10 / Linux, and the second is only used for Bitcoin Core and the blockchain.

Hello, can the specifications of the device be upgraded?
And that this device has a health guarantee and will also be sent to Turkey?

Hello.
You can change the hard drive, but nothing more. The computer was under warranty for another 6 months. And yes, I was able to send it to Turkey.
But the computer is already sold. Thx for your interest.

It is already possible without needing anything new.
The part about locking coins and only releasing them under a certain condition (sale going through) is done using multi-sig with 2 parties (2 of 2). The part about locking the coins for X hours is done using OP_CHECKLOCKTIMEVERIFY and to combine these two each part can be seen as an expression inside OP_IF and OP_ELSE.

Thank you for this very interesting information. After a quick search, I found this interesting article about this smart contract feature implemented by Peter Todd, and the possibility of creating a trustless escrow : https://bitcoinmagazine.com/press-releases/yes-bitcoin-can-do-smart-contracts-and-particl-demonstrates-how
How is this different than Al just keeping control over the coins until he's ready to send them to Bob?
In both the "locked coins" system (without unlocking) that you are trying to invent AND in the scenario where Al doesn't send the coins, Bob never gets control over the coins at all.
Also in both the "locked coins" system (with eventual unlock) that you are trying to invent AND in the scenario where Al sends the coins eventually, Bob gets control over the coins when Al finally decides to let him have control.
The only difference is that in your scenario, there is a short period of time when NEITHER can spend the coins. I don't see how having such a period of time provides security to either party, since either could just wait out the time.

The purpose is to give Bob proof that Al has enough coins to complete the transaction, and to be sure that he won't spend them.
I once had an annoying situation with someone who asked me lots of questions about the house/business/etc I was selling. He argued with me for days, only to tell me he didn't have enough money to buy.
My idea sounded good on paper, but it is apparently very difficult to implement because of the way Bitcoin works (and is probably not the best solution). I also wished to respect the "without a trusted third party"
credo of Bitcoin. My motivation was to provide proof that the customer is "solvent", especially for a busy person or a professional, rather than to provide better security.
Wouldn't you just have the guy send the transaction, and then once it's confirmed give him the keys?
Same as above. This idea was designed to be used in a specific situation, with expensive goods, real estate, etc, most likely by a professional. This system also offered a way for the buyer to show that he has
enough money, without sharing all the info/balance of his wallet with another party. You may say that this is not important because if the buyer does not have enough money, the transaction will simply never
happen, but the advantage is to get this information quickly.
Thanks to everybody for your interesting comments.
Possibility 1: We sign the sale and I send a confirmation of the release.
Possibility 2: The sale does not take place and I automatically get my 10 BTC back after X hours.
Use a third party escrow who also know the things about property or whatever industry you are trading. You will send them the coins, they will hold the coins for your and the other guy. The escrow guy will monitor the activities from both of you. Once you two agree and satisfy with the deal then he will release the coins to the other guy or he will give you your coins back.Possibility 2: The sale does not take place and I automatically get my 10 BTC back after X hours.
There are no such lock system because who know you could misuse it. After having everything okay you still can sent those coin back to you instead of paying the seller.
In my example, Albert's 10 BTC are already in Bob wallet, but locked for X hours, unspendable by Bob.
If they are not in Albert's wallet, how can Albert spend them again?
I imagine the lock having 2 options: 1 - If nothing happen, the 10 BTC return to Al wallet. 2 - If Al lock is cancelled, Bob can move the coins.
Is it already possible, or can it be added to the Bitcoin code, to send blocked coins? Releasable under certain conditions?
A quick example:
You sell your house for 10 BTC. I am interested. You ask me a proof that I have 10 BTC. I send them to you, blocked, with an automatic return within X hours.
Possibility 1: We sign the sale and I send a confirmation of the release.
Possibility 2: The sale does not take place and I automatically get my 10 BTC back after X hours.

OK! So this Lightning Network isn't THE real Lightning Network ? 
https://coinmarketcap.com/currencies/lightning-bitcoin/
That's probably better to use Lightning than a custom layer 2.

Maybe waiting until the block limit is reached can be a good solution, but it can be very slow.
Lightning would have been good, but I have one big problem: the value. 1 BTC ≠ 1 LBTC. Because of this, it is possible to lose a lot of money due to price fluctuations.

That's an example.
You can imagine that's a private network for McDonald's with a node in each of their hundred thousands restaurant all around the world.
Guys are used to Bitcoin Core, and they want something as familiar as possible for their employees. Speudo-anonymous, backed with Bitcoin, etc.
As I said that's just an example.
Is it possible to stop the block generation when mempool is empty?

Hypothesis: a private group wants to create a 2ᵉ layer blockchain to facilitate its internal payments. The aim is to keep costs as low as possible, as well as energy and disk space consumption.
Important detail: the network is centralized. To transfer BTC, you just have to send your Bitcoins to the private group address, and specify your other address on this layer 2.
To save disk space, when nobody uses the network, the blockchain is simply deleted.
For energy consumption and costs, the first idea is to keep the mining difficulty at 1 forever. The second is to stop block generation, without disconnecting the network.

Re: Est-il toujours difficile d'acheter des cryptos en afrique du nord?
Oui, c'est interdit au Maroc et l'interdiction, de ce que je sais, semble globalement respectée.
Oui, ils se font arnaquer par Western Union.
En revanche, une certaine boîte algérienne qui vend des abonnements de télévision sur ip accepte les paiements en BTC.

Et en Algérie et Tunisie, Bitcoin est autorisé?
Est-il toujours difficile d'acheter des cryptos en afrique du nord?
Voilà la question.
Est-il toujours aussi difficile pour nos amis Marocains d'acheter des cryptos?
Arrivent-ils à ouvrir des comptes sur les échanges?
Se font-ils arnaquer comme avec virement Western Union 3 fois plus cher que n'importe ou ailleurs?

La vraie question: L'aimes-tu encore ou non?
Si c'est non, quitte là.
Si c'est oui, parle avec elle. Achète-lui de la nouvelle lingerie, séduis-la de nouveau. Fais-toi beau. Fais du sport. Surprends-la.

The day of the 12th Genesis block Birthday, I received my holy grail by email : a copy of the missing Ecash white paper!
To be honest, I don't know if I can trust 100% this is the real one, but it looks Legit.
