How Bitcoin Mining Be Vibin'

How does Bitcoin mining work?

So like, in the vibe check earlier, you learned what a Bitcoin miner is, how it stashes fresh transactions in its memory pool, and then kicks off the “mining” process by crafting a candidate block. 🚀

If that just sounded like alien speak 🚀, go vibe with the first lesson of my Beginner’s Guide to Bitcoin Mining.

If you’re still vibin', let’s snoop closer at the candidate block… 🤔

Kinda like how you can be split into two with a noggin and a bod, a candidate block's got:

1. Block header (yellow vibes)
2. Block body (gray vibes)
   

A closer snoop at a candidate block reveals it's NOT just about transactions. 👀

When a miner drops a candidate block, it vibes with a “block header” (yellow zone).

The “body” (gray area) holds the transactions like a TikTok trend. 💃

Apart from transactions, candidate blocks have some dope metadata that gives the block a “TL;DR” vibe.

Metadata is just spicy deets about other deets. In this sitch, it's all about the block. This info is tagged as the “block header”.

Peeping inside the block header, there's some crucial data.

To keep it 100, we’ll simplify what's chillin’ inside the block header.

Timestamp

The first piece of action inside the Block Header is the “Timestamp”.

The timestamp timestamps the vibes when the block was born. ⏰✨

Previous Block Hash

The next tea is the “Previous Block” or specifically, the “Previous Block Hash”.

The Previous Block Hash is like the block hash throwback to the last gem in the blockchain. 🔗💾

To get this tea, we gotta peek the file. 🔍

When we zoom in on the file, those data vibes are structured for the perfect pic. 📚

Time to visualize this as the blockchain. ✨

The candidate block the miner beeps out gotta chill on top of the most last-gen block. 🧱💡

The most recent block is deep blue aesthetic. 🌊

Peeping the Block Hash in blue means it’s THE recent block in the blockchain holo deck. That’s the one the miner is aiming to drop its block vibes on. 🚀🔗

Think of the Block Hash as the block's signature dance move to stand out. 🕺💎

So, the miner's gonna pop this as the “Previous Block Hash” in the Block Header of its OWN candidate block. 💾✨

“Transaction Summary” Hash

The next flavor in this data soup: the “Transaction Summary” Hash.

Like, it's the SparkNotes of all block transactions, nothing but vibes in strings. 📚✨

No need to vibe deep, but all transactions (spotlit in red) are tossed into a hash blender and squished into one magical single hash.

 

This hash is chillin’ as the “Transaction Summary” Hash.

This hash pulls a unique ID – a.k.a. a “fingerprint” – for all the transactions birthed in a block, stopping any shady tampering. 🔒🖼️

Heads up, this “Transaction Summary” Hash goes by “Merkle Root“. 🤓

Remember, tiny tweaks in data rock the hash world, leading to a new hash ID. If one tries playing remix DJ 🚨 with any of the block's past transactions, it triggers a hash transformation, too, different from the OG value chillin’ in the Block Header.

Basically, remixing a transaction whispers hints of foul play, so everyone can clock the cheeky business. 🚨🧊

This reversible change immediately snitches that a transaction did the dirty. 🙅‍♀️

Block Hash

Rolling so far, the Block Header's got three secrets:

1. Timestamp ⏰
2. Previous Block Hash 🧱
3. “Transaction Summary” Hash 📚

The next stop? Toss this Block Header data into a hash function blender. 🌀

This action creates a sick random number crown called the “Block Hash”.

(A . more accurate call would vibe as the “Block Header Hash” since it’s the crown over the block head, not the vibe sheet.)

Like the Previous Block Hash – treat the Block Hash like a custom-generated ID number righteous for a new era candidate block. 🕺💎

Why do this check, miner?

To slay in the blockchain, miners need to channel a Block Hash that fits in the criteria. 👨‍💻

If that standard ain't met, the block needs to sit out, and the miner can’t add it to the blockchain party. 🚫📈

Specifically, the Block Hash has gotta be code for a number giving zero vibes, kickstarting with a precise zero fest. 🔢⛓️

How many zeros we talking?

The system software peeps the minimum zero clubs expected of the Block Hash's debut.

OG days asked for a shy zero lineup, but with more mining players, Bitcoin shifted those expectations up on zeros. 💪💾

A miner's gotta shape a Block Hash that nails the output vibes the system strokes out.

This zero bar sets the output zero zone that the Block Hash should hit.

Think “limbo” like a party trick. 🎉🤸‍♀️

The lower this limbo pole (threshold), the jollier the zeros needed. 🎯

The more zeros the block demands, the higher the grind difficulty is to shoot a “correct” Block Hash. ⛏️

Lotsa zeros calls for less spot-on solutions, meaning more time for that Block Hash fortune find. ⏳

Snagging a vibe that syncs with three zeros like “000123…” is legit harder than a six-zero trek like “000000123…” 💪

Check this legit sample of a prized Block Hash:

0000000000000000000586b367c292dfd274bf2e67575cf8b4d00735fc1df6ff

Catch the zero stretch it kicks off with? 😎

The “certain number of zeros” is from the block’s fierce stat “mining difficulty”. So, the chill Bitcoin software auto-tweaks it based on miner headcount. Crammed miner streets make the number of zeros the system flexes more, upping the bar for winning nonces.

A Block Hash is one massive large number patrolled under a certain bar. That’s why the zeros parade comes before the alpha string ID. Some dig sites hit up to twenty zeros, while baby blocks kept it around eight. The zero squad shows how tough the block's mining was during its launch time.

What if the Block Hash flunks the zero school requirements?

The block will NOT get on the blockchain guest list.

Luckily, the miner’s got infinite retries. 🎫🔄

But hashing the Block Header on repeat with the same Timestamp, Previous Block Hash, and “Transaction Summary” Hash post-spazzing fails, guarantees the same turnout.

The miner needs a remix on the data jam before hashing Block Header again.

Bitcoin said, “Easy.”

The Nonce

In there, the Block Header messes around with an extra field for the “nonce” (light blue swag)

The Core Part of Block Header lets miners freestyle with random figures for the nonce corridor.

Miners flex to drop any numeral vibes they dig in their own space. 🎲🔢

The nonce doesn’t dabble with transactions; it's independent, made for miners to stuff in all the digits they favor, making shifts if the Block Hash sonically starts with zero-less notes. 🎧🔥

The nonce is a scalpel to slice output vibes from hash functions finely to “guess” the goal. ⚔️🤖

Since switching any other Block Header data means trading hacks, nonces vibe as the change pieces. 🎛️🔀

As one attempt bites the dust on hashing the Block Header, miners switch up the nonce tune. 🎵

It’s like hunting down that combination safe lock. 🔐🔄

There ain't a shortcut in that map to the dungeon's secret number. Every possible combo’s gotta be eyeballed 'til you strike gold by hit-or-miss. 🙈💥

You guess, rinse, rinse again until you luck up a pot!

Testing a lock’s combination for the right moment? Quick legit chore, making it a speedy breeze for miners and their gnome nodes to recheck if the nonce is absolute jams for real. ⏰💪

The miner is fringed up against other miners. First miner hitting the nonce lands a block for blockchain honors, trophies loading.

For an example, if the Block Hash has to salute with at least four zeros, then only randomness can spearhead nonce figures and blocks through the hash function.

Imagine a miner starts nonce value (light blue drive) at “0”.

If that’s a no-go, the miner has to go in with a new different nonce.

The miner readjusts the nonce and vibes fresh, while keeping its eyes on claiming a Block Hash with at least the demanded zero roll-out. Here, four zeros. 🎯

Remember, even minor changes will lead to vast distinctions in the hashing results. Change the nonce – change the vibes. 🔄☄️

So, the first play from miner was to set nonce to “0”. Running Block Header through the hash function sees if Block Hash initiates with quadruple zeros.

Checking, the Bloch Hash only led with two zeros, ergo flunking the grade for the blockchain guest list. 🎟️📈

If the output shows ‘invalid’, the miner guns through different nonce vibes.

'0' did not vibe, so switch to Nonce “1” (light blue zone), hashing the Block Header again. 🔢🔄

The Block Hash came with no zero parade, big letdown.

An L for “1”, miner turns Nonce to “2” (light blue vibes) then powers Block Header through hash function again. 🔄🙅‍♂️

Four zeros in Block Hash, criterion locked in place – NAILED IT! 🎉🎯

As you can tell, predicting the nonce is pure wild – so miners keep nonce picking to strike the gold. 💰💡

Miners dig deep, often with zilch guarantees of landing a thrilling nonce. Most won't win!

The nonce works as a counter, its digits being flipped until a Block Hash clicks, or another miner beats ya to it.

It’s like a number guessing game!

In its essence, you’re fishing for a hash armed with zeros via nonce gaming.

Miners repeat ad infinitum…HOPING that output will craft a Block Hash on the winner's block ticket. 🔄🏆

More epic computer power leads to more "guesses" landing.

All this testing is dubbed mining. ⛏️🔔

The “winning” miner bags the prime of bitcoin (plus transaction fees) called the “block reward.” 💰🎯

Once every 10 minutes, one miner hails the block reward.

Mining seriously calls for deja vu:

Batch up Block Header with nonce sticks, hash it, check if the hash beams with the least zeros, otherwise rerun process with a varied nonce.

Just thinking about it makes me want to ZZZ. 😴

When they say mining's all about getting ‘“solving complex math problems”, you know it gets lost. ✍️

Mining is basic logic gymnastics!  It’s Easy-peasy. Just try to guess a number and dare to be quick or sharp enough to spark being the FIRST to guess it right so your candidate block hits the blockchain main stage. That's ALL

When the buzz is about “Hash rate”, it means the guessing muscle of mining setups. Speeds you guess per second, steers up your hash rate. Stretch to 1T (1,000,000,000) = holding down 1 Terrahash (TH/s).

A simple run-through ain't a cakewalk. Hence the name “mining". You’re virtually going “digging” for that gold-number. Diamonds come after some real labor, minus picking dirt. 💎⛏️

Mining juices just arrived nonce for a Block Hash respecting requirements (hailing 4 zeros or more), casting it on the miner’s blockchain script. 📀🎉

Peep forward to when blue block reigned as the freshest on the miner’s blockchain? Zeroed out now.

With the miner nabbing a grade-A nonce, green-colors its block on the blockchain.

Both from a chill view, the future based file on the miner’s tech got refreshed (green-flair shout).

And so, the node now broadcasts this block to its network node bros connected nearby.

The receiving nodes scan, validate and check to be certain the Block Header vibes with Block Hash set criteria. Breaking ground, the Block Hash started with four zeros as the criteria.

Nodes up their files tuning to add this block.

Their files come checked and matched just like the miner's winning version (green flag file).

Every transaction in their tech stash scope shifted to “confirmed” and gets permanently added to the mix.

Incompatible transactions face ejection.

Thanks to mining's roll, the purple one makes it into blockchain history.🙌

And nodes pass along that block baton.

With new block, general miner cheer hits, everybody scribbles onto a shiny candidate block, wind back mining cycle mode. 🔄🏆

Mining flexes as a transaction DJ master over computer networks; “mined” blocks hoist quality beats crucial for blockchain credibility.

The fledgling Block Hash is a miner’s easy street for the “Previous Block Hash” on their candidate blocks' next edition.

The Block Hash heads as the “chain”.

Miners gotta always nest the previous block’s Block Hash in the new block they're crafting. 📦🔗

Sample scene shows, block 101’s gotta know block 100’s hash, to hop on it.

'Til block 101 claimed history, block 102 needs to cue in line.

Such ensures block 101 gets miner spotlights, eternally marked by block 100. Skipping isn’t welcome.

But rather than turning lines with “block number”, each block bounces back on its “Bock Hash”-worthy sway.

Implying each block links, thus creating a chain of blocks, ya might know as THE blockchain. ✌️💾

“Chain of blocks” via honor not from block numbers but from block hashes. 🔗🌐

Why You Can’t Pull Fast Ones with Bitcoin

Scenario time: Everyone's jamming block 101 tuning hits.

But some miner's salty, want block 80's tune remixed. 🔥🚨

Someone’s got pearls to tweak and redo all calculations for blocks 80-101 plus do block 101.

Wowza, 21 blocks with diamond-rated computing!

And beat the clock to also land around block 101 before other crews done hum-blocking on Bitcoin's network. Odds are toast.

Pulling fast ones on transactions coded into the blockchain is nearly off-the-grid.

When they tag blockchain legit untouchable.

Proof-of-Work (PoW)

The mining grind is often called “Proof-of-Work” or PoW.

PoW stands as Bitcoin’s squad check on the “official” blockchain copy. No mediator needed to steer disputes or interference.

“Proof-of-work”, tagged, explicit highlights “work” needed to nudge a block hash with numbered precision. And once you do, anyone peeping it validates your “proof”.

Nonce guessing tic influences the block header hashing, pioneering the way to testify done “work” on one’s block.

First miner dropping valid hash wins endless block laurels, bitcoin wins.

Should the mining engines flood the Bitcoin scene, PoW ratcheted up difficulty for legit hash blocks. Say miner surge fizzles, discouraging lots from mining, easing level vibes rock 'n' rock.

This loop, aka the difficulty adjustment, wheels every two weeks, assures fresh blocks troop onto the blockchain at a 10-minute suite, no stress on miner members present.

Adjustment works show mining heat.

Tuning difficulty locks in Bitcoin’s mint clip at all times, no supplies over mining hustles!

Finesse levels stop miners bombing the bitcoin supply's clip groove.

Digitally charged mining tech & electricity = uneconomical hacking vectors. Guessing secures Bitcoin's infrastructure grid.

Anyone hacking the chops must attest mining truth & bag block’s song blessing (nanocoins and transaction sauces).

Recap Jam Session!

Yay! Blossomed mindset on how mining hurdles Bitcoin:

• Miners eye an ace hash to crown as “Block Hash” by nonce tickings, hashing, checking vibes.
• If hash ain't zeroed correctly, miners tune in the nonce, repeat hashing, and tick checking again.
• The moment miners land on a nonce, destiny fulfilled the blockchain fame, they get cozy with block rewards. 🎯
• Once assured by node majority, the winning miner's block bonds with the blockchain for good.
• All miners flip and set sights shaky on a new gold block.
• That vibe cycle called “Proof-of-Work” (PoW): nonce threading.

Now that we get miners and their grooves, let’s amp Bitcoin's system decks:
