Sei seduto davanti al tuo computer. Non hai bisogno di alcun conto bancario, nessuna carta di plastica, nessun numero di previdenza sociale con il quale identificarti, nemmeno un account email. Hai solo bisogno di una chiave privata sotto forma di una sequenza causale di caratteri che hai generato in precedenza attraverso alcuni semplici passaggi crittografici automatizzati. Questa chiave privata è tutto quello di cui necessiti per effettuare un pagamento, mandare denaro a una buona causa, perfino votare per un sondaggio o un referendum online

💊 Candidate Block
A candidate block is a temporary block created using transactions selected from the memory pool.
Nodes (mining nodes) select transactions from their memory pool to form their own candidate blocks.
Anyone who is mining can choose which transactions to include in their candidate block.
Each node then tries to add their candidate block to the blockchain through the process of mining.
Every block starts life as a candidate block, but only the ones that are successfully mined get added to the blockchain.

💊
Mempool
"stoccaggio e memorizzazione" temporanea delle transazioni ricevute da un nodo.
Quando un nodo riceve una nuova transazione, la tiene nella sua mempool insieme a tutte le altre transazioni più recenti ricevute. Da qui la transazione "spera "di essere selezionata per essere inclusa nel blocco candidato (candidate block)
In pratica, la mempool è una sala d'attesa per le nuove transazioni.

2023-04-18 08:15:25

💊
Memory Pool
Temporary storage for transactions that have been received by a node.
When a new transaction is received by a node, it will hold it in its memory pool with all the other latest transactions it has received. From here the transaction will be hoping to get selected for inclusion in the candidate block.
So basically, the memory pool is a waiting room for new transactions.

Assuming connecting it to a 27" monitor (150W), and playing it 2 hours a day, each PS5 would consume
0.15+1.15 =0.3 kWh x 2 hours = 0.6 kWh/day
and 219 kWh/year
There are about 32,000,000 PS5s in circulation, so the total annual consumption "due to PS5s" is
219x32,000,000=7,008,000,000 kWh/year = 7 TWh/year

How Much Electricity Does A PS5 Use?
The PlayStation 5 uses between 50 and 200 watts when in use, although it is rated for a higher wattage which it may use with more advanced games or when working with PlayStation VR in future.
Here’s how the PS5 compares to other consoles of this generation:
Console Watts used
PlayStation 5 50-200
Xbox Series X 45-200
Xbox Series S 25-100
Nintendo Switch 10-18

Come cambiare DNS in linux
1) Apri /etc/resolv.conf con un editor di testo ed i privilegi SU
- sudo nano /etc/resolv.conf
2) Aggiungi la dicitura nameserver ed il relativo indirizzo DNS
- nameserver 9.9.9.9 #QUAD9DNS primary
- namesever 149.112.112.112 #QUAD9DNS alternate
3) Salva
- Ctrl + X
- Y
4) Verifica che i DNS siano cambiati con il comando "dig"
Note : con questa procedura cambierai i DNS temporaneamente fino al prossimo riavvio del sistema
Ti consiglio di impostar i DNS di https://www.quad9.net/
Quad9 offre un servizio gratuito che sostituisce l'ISP predefinito, protegge il computer, da un'ampia gamma di minacce come malware, phishing, spyware e botnet e può migliorare le prestazioni oltre a garantire la privacy.

💊 Entropy to Mnemonic
add a checksum to our entropy to help detect errors (making the final sentence more user-friendly). This checksum is created by hashing the entropy through SHA256, which gives us a unique fingerprint for our entropy. We then take 1 bit of that hash for every 32 bits of entropy, and add it to the end of our entropy.
Entropy + CheckSum
Next we split this in to groups of 11 bits, convert these to decimal numbers, and use those numbers to select the corresponding words.
(BIP39 Wordlist The words in a mnemonic sentence come from a fixed list of 2048 words - specified by BIP39 -. The first 4 letters of each word is unique in the list)

Messy pills
HD Wallets - Mnemonic Seed (BIP 39 standard)
From Entropy to Seed
1. Generate Entropy
2. Entropy to Mnemonic
3. Mnemonic to Seed
To create a mnemonic you first of all need to generate entropy, which is our source of randomness.
You can think of entropy is being a very large random number that nobody has ever generated before, or will ever generate in the future. It’s also best to think of this number as a series of bits (e.g. 10011010010001...), which is how computers store numbers.
(The entropy we generate must be a multiple of 32 bits, as that will allow us to split the entropy up in to even chunks and convert to words later on. Furthermore, the entropy should be between 128 and 256 bits, as that’s enough to make it impossible for two people to generate the same entropy)
Entropy: 11111011100010110101111111111001101010001001101110000010010100010110101011011111100000101111000100101101100010111100101101111101 💊

Messy pills
HD Wallets - Mnemonic Seed (BIP 39 standard)
A mnemonic sentence (“mnemonic code”, “seed phrase”, “seed words”) is a way of representing a large randomly-generated number as a sequence of words, making it easier for humans to store.
These words are then used to create a seed, which can be used for generating extended keys in a hierarchical deterministic wallet.💊🗝️

Bitcoin is stored on the blockchain.
Miners don’t validate tx nodes do. Miners just choose to include them or not in the next block.
There will be slightly less than 21M due to the math.
You pay a fee as an incentive to be included in the next block
