🟠 What is the Bitcoin opcode that compares two values? 👉 OP_EQUAL OP_EQUAL is an opcode in Bitcoin Script that checks whether two stack elements are equal. If the script execution leaves TRUE on top of the stack, the transaction is valid; if it leaves FALSE, it’s invalid. 🫶 A simple principle – but critically important for validating transaction conditions.

And right now, it’s critically important for you to grab your XP in the game 😉

👾 What component determines the transaction ordering inside a block? 👉 Merkle tree structure The Merkle tree structure defines the order of transactions inside a block. Thanks to it, every transaction takes its place in the hash hierarchy.

🫶 Is solo mining really possible? Good news for those who dream of mining BTC solo one day – you actually have a chance. 👾 Statistics show that the share of solo-mined blocks in the Bitcoin network has increased by 17% over the past year. In total, 21 solo miners successfully found blocks, averaging one block every 17.2 days, collectively earning 66.16 BTC. 👏 One of the lucky miners didn’t even use their own equipment. They spent just $75 to rent 1 PH/s of hashrate – and managed to find a block. ❤️ ECOSMiningGamebot

🤑 What value determines the block’s proof-of-work goal? 👉 Difficulty target This value sets the threshold that a block’s hash must be below. The lower the target, the harder the mining – and the more computations are required.

Good thing claiming your XP in the game doesn’t require that much effort! 🚀

🤓 What is the name of the memory area storing unspent outputs? 👉 UTXO set UTXO (Unspent Transaction Output) refers to transaction outputs that haven’t been spent yet. It represents the amount of cryptocurrency remaining after a transaction, which can later be used in a new one.

👾 What is the term for blocks containing only a small number of transactions? 👉 Empty blocks These are blocks that contain very few transactions (sometimes only the coinbase transaction). This happens when a miner wants to publish a block quickly instead of waiting for the mempool to fill up. 🚀 Fewer transactions – faster block propagation.

Now hurry up too and jump into the game to grab your XP. 🫶

👾 Crypto News: Weekly Overview 🗓 February 23 – March 1 It's Monday again, so we're publishing a digest of key events in the crypto market over the past week. Let's take a look at what's been happening this week. ▪️Strategy acquired an additional 592 BTC worth $40 million, while Bitmine added 51,162 ETH ($98.33 million) to its balance. At the same time, GD Culture Group decided to sell all 7,500 BTC, locking in a drawdown of around 41%. ▪️Bitcoin briefly dropped below $64,000 amid a series of macroeconomic shocks, including mass unrest in Mexico and a decline in the U.S. pending home sales index. Another negative factor emerged on Saturday with an attack on Iran. However, by Sunday evening, the leading cryptocurrency managed to recover its losses and climb back above the $67,000 level. ▪️Meanwhile, a theory has been circulating within the crypto community linking the current Bitcoin correction to the actions of the investment firm Jane Street. We'll be back soon with more updates – until then, stay tuned! ❤️ ECOSMiningGamebot

🫶 What is used to compress block propagation between nodes? 👉 XThin or Compact Blocks These methods reduce the amount of data transmitted between nodes when a new block is shared. Since many transactions are already known to peers, only the missing pieces need to be sent.

🤑 What is the name of Bitcoin’s difficulty retarget interval? 👉 Retarget period In Bitcoin, it spans 2,016 blocks – meaning the network adjusts mining difficulty roughly every two weeks.

👾 What is the special output in the coinbase transaction called? 👉 Coinbase output It’s the special output in a coinbase transaction through which a miner receives the block reward. This is where both the block subsidy and transaction fees are credited.

✉️ What broadcast method do miners use to announce a found block? 👉 INV message When a miner finds a new block, they broadcast an INV message to other nodes. This lets the network know a new block exists, prompting other nodes to request and verify it.

🤑 Who Created Bitcoin and Where Is Satoshi Nakamoto Now? We continue building our crypto knowledge library so you can gradually become a true guru! Today, we’re answering a question almost every newcomer asks: who created Bitcoin? 🗓 Bitcoin was created by a person (or group of people) under the pseudonym Satoshi Nakamoto. In 2008, Satoshi published the Bitcoin whitepaper, and in 2009, launched the network. But here’s the most intriguing part: Satoshi’s real identity remains unknown. He (or they) disappeared in 2011, leaving behind the code, a growing community, and a fully functioning network. 🍦 As a result, Bitcoin has no founder who can “come back and change everything.” Satoshi stepped away, yet the network continued to operate – and it still does today. That’s what makes Bitcoin unique: it lives and evolves thanks to its rules and the participants who follow them. 👀 What do you think – will Satoshi ever reveal their identity? ❤️ ECOSMiningGamebot

🤓 What is the term for spending multiple UTXOs in one transaction? 👉 Input aggregation In such transactions, more than one signature is normally required — one for each input. Cross-input signature aggregation helps reduce the total number of signatures to just one, making transactions more efficient.

🫶 And your XP should definitely be higher — especially if you jump into the game right now and claim it!

🤑 What is the primary communication protocol Bitcoin nodes use? 👉 TCP/IP 🍦 Bitcoin nodes exchange data, broadcast transactions, and relay blocks through TCP/IP – without this core internet protocol, the network simply wouldn’t function.

Combo Code: 123321 ❤️ ECOSMiningGamebot

🧐 What protocol allows nodes to relay blocks faster than full blocks? 👉 Compact block relay This protocol reduces redundant data transmission, since many nodes already have most of the transactions included in a block – sending the full block isn’t necessary.

Be fast like Bitcoin – jump into the game and grab your XP.🚀

👾 Crypto News: Weekly Overview 🗓 February 16 – February 22 For several weeks now, we’ve been starting every Monday by discussing the key events in the crypto market over the past week. Today is no exception – so let’s take a look at what stood out this week. ▪️Mining difficulty rebounded by 15% as the hashprice fell below $30. ▪️The Sharpe Ratio is signaling a potential near-term recovery for BTC. It has dropped to a level that has historically preceded price bottoms, as noted by a CryptoQuant analyst. ▪️Crypto funds have reduced their BTC exposure to zero for the first time, cutting the share of risky assets to 40% of their portfolios due to a deterioration in the risk/reward profile. We’ll be back soon with more updates – until then, stay tuned! ❤️ ECOSMiningGamebot

🤔 What is the economic model where supply decreases but demand stays? 👉 Deflationary model A deflationary model in crypto is a mechanism that gradually reduces the number of tokens in circulation, which can increase the value of the remaining supply over time.

🟠 What is the term for upgrading Bitcoin rules without splitting the chain? 👉 Soft fork A soft fork does not create a new chain – it simply modifies the existing one. A well-known example is the SegWit upgrade, which optimized Bitcoin’s transaction structure without splitting the network.
