Unspent transaction output is the maim accounting system that works in the Bitcoin protocol, which primarily tracks spending of Bitcoin and ownership.when someone sends you Bitcoin you don't necessarily receive Bitcoin per say but Instead you receive UTXO's which are pieces of Bitcoin locked to your wallet address, infact your balance is a summations of all UTXO'S that is associated with your your wallet. Simply put UTXO describes the flow of value in the Bitcoin BlockChain because UTXO tracks down the flow of information on the block by keeping records of the chronological records of every Bitcoin transaction  that is ever made.

How dose UTXO Work

It should be noted that every Bitcoin transaction that is made has two parts which are the input and the output parts. Input parts are the already existing UTXO'S on your wallet while the output are the UTXO'S that is been created which is usually sent out . For example if I want send out  Bitcoin to someone. Let say I wants to send 0.4 worth of Bitcoin to someone named X, and assuming that I have up to 1BTC on my wallet.

UTXO X= 0.4BTC been sent to X.
0.0599= is back to me as change.
0.001BTC = miner's fee.
At the end of the day I have been able to spend 1BTC, it should be noted that, UTXO that has been spent is lost forever and is replaced by new UTXO'S.UTXO'S are the  global list of all currently unspent outputs Stored and maintained by full Bitcoin nodes which are currently used to quickly verify if a transaction is valid or not on the Bitcoin BlockChain.If an output is not in the UTXO set, it cannot be spent.

Why Bitcoin Uses the UTXO Model

Strong Security
Prevents double spending each UTXO can be spent only once.

Easy Verification
Nodes don’t need account balances they just check if the input UTXOs exist and are unspent.

Parallel Processing
Multiple UTXOs can be verified simultaneously
Improves scalability.

 Better Privacy
No global balance per identity users can generate unlimited addresses.

McTominay and Hojlund, players who left Manchester United, are carrying Napoli. Manchester United is such a team that all the players who leave them become stars.
Napoli managed to win three points with two goals away from home. Throughout the match, Napoli waited for the right moment without panicking. They controlled the game thanks to their passing connections in midfield. The goals scored were in line with the overall flow of the game. In defense, Napoli was quite balanced and made no mistakes.

Another loss, this time to team buwaytress. Can it get any worse than this?
My league form is like Bitcoin chart - from bad to unimaginable.

Didn't expect to be beaten by the worst team the league has to offer, that probably means that the title is mine to carry now.

To make it worse, Trofo mentioned in BSFL chat it was Mozambique's first AFCON win in 40 years. They didn't even need to win, just draw, but when you lose, you lose.

I'm in 13th place. Nothing to shout about. Really need to buck the hell up here.

Instead of buying accounts why don't just build yours, if you are a knowledgeable person you will grow the account very quickly.
I remember back in 2018, people didn't need to build account visibility/reputation to start earning on bounty boards.
People bought brand new accounts because the ones they created couldn't post anything and didn't know anything about the ip limit. So beginners bought fresh accounts (perhaps a large number for farming).
I think this practice still persists somewhere, even though bounty campaigns aren't as popular as they once were.

1. Quantum Computing and the Potential to Break Bitcoin’s Security:

One of the biggest risks to Bitcoin’s future is the development of quantum computers. These machines have the potential to perform calculations far faster than today’s classical computers and could break the cryptographic algorithms Bitcoin relies on (like ECDSA – Elliptic Curve Digital Signature Algorithm). Quantum computers could "unlock" private keys on the blockchain, making Bitcoin transactions vulnerable to hacking.

If quantum computers can break Bitcoin’s security, could we create a new version of Bitcoin with stronger encryption? Or would there be a different digital currency that takes over?


there is this fear that the quantum computing will be Able to break bitcoin security that the bitcoin encryption work on there by getting to expose our private key making our asset vulnerable. but i still do not agree with that i think the Elliptical curve multiplication is not and easy way going back even with the quantum computing.

and even if that happens there will be a measure that will be put in place probably an upgraded  security system that can compete with the quantum computing speed. but i do not think there will be need to create another version of bitcoin again. just an upgrade on the encryption should be  enough.
totally get ur point and thx for bringing this up! but yea, that quantum FUD gets overhyped imo. ECC is a beast to reverse even for QC—like trying to find a needle in a billion haystacks, but the haystack is on fire lol.

and ur spot on… if that day ever comes (wayyy off), devs would likely just push a soft fork with quantum-resistant sigs. no need for "bitcoin 2.0" or starting over. the network upgrades, we keep chillin.

Despite constantly printing money, the USD is still very strong. When you look at other developed and developing countries, you can see the difference. Many countries are struggling with inflation. Money is losing value day by day. If we assume that all currencies are losing against inflation, the USD is one of the least damaged. Even though the USA isn't being governed well, it's still the number one power in the world and that naturally reflects on its currency. I don't see that changing anytime soon.

You're very correct. Normally overprinting of money causes hyperinflation, countries like Zambia and Venezuela have trued it before and suffered the consequences and that's because their currency is not as strong enough or recognised like the US dollar.
 The US dollar is very strong because it's used globally for international trade, more recognised than other currencies internationally, even the likes of pounds and Kuwait dinar that's valuable than it, so anyone thinking that the US economy would crumble cause of over printing should dig deep, do proper findings and rethink their thoughts cause the usd is the global reserve currency, it's gained trust international compared to others which is why the US economy is still sustained despite more printing.

We are very pleased to announce our new referral system!

Whenever your friend makes a new account, you will start earning 2.5% of the house edge (rake) on every bet they place - LIFETIME.
Win or loss does not matter, it is based purely on volume of placed bets.

Example:
If your friend wagers $1,000 on markets with 3% margin, the rake is $30, you will earn 2.5% = $0.75, no matter the bet outcome.
On higher-margin live markets (e.g., 8%), $1,000 wager will result in $2.00 pure profit.

Payouts are daily, and as mentioned above - it does not matter if your referrals are profiting or losing, you are getting a share of their bet volume.
Join us, level up your referral system & earn together!

::Porfirii//
Alguien me acaba de pedir una dirección BTC y como estaba por ahí por el Lobby de Electrum, me acorde de este hilo, y me dije  "vamos a conocerle la firma a Porfirii" y nada, ni para las Tapas logre sacar nada. (no la pude verificar)


En todo caso dejemos por aquì el formato, por si alguien logra confirmar:
