🤓 What is the name of a lightweight client that doesn’t store full data? 👉 SPV node It is a type of node in the Bitcoin network that verifies transactions without storing the full blockchain. Such nodes are suitable for devices with limited resources (smartphones, tablets, etc.) and are commonly used in crypto wallets.

🗓 Crypto News: Weekly Overview March 30 – April 5 It’s Monday again, so here’s our weekly digest of key events in the crypto market. Let’s take a look at what happened over the past week. ▪️Bitcoin posted its worst first quarter since 2018, with its price dropping by 22.2%. Over the past six months, the leading cryptocurrency has declined by more than 40%. This marks the weakest start for the asset in the last eight years. A larger drop at the beginning of the year was recorded only eight years ago, when Bitcoin fell by 50% – from $14,112 to $6,973. ▪️Google has lowered its estimate of the quantum computing power required to break Bitcoin. According to their analysis, fewer than 500,000 physical qubits may be sufficient – 20 times less than previous estimates. ▪️Fidelity analysts described Bitcoin’s 52% decline as a sign of market maturation. In the past, after reaching all-time highs (ATH), Bitcoin would drop by 80–90%. Now, post-peak drawdowns are less severe, and this trend is likely to continue. We’ll be back soon with more updates – until then, stay tuned! ❤️ ECOSMiningGamebot

👾 What is the term for a node that stores the entire blockchain? 👉 Full node This is a node that downloads and stores the entire blockchain, independently verifies all transactions and blocks, and enforces the network’s rules without relying on third parties.

🔎 What is the term for splitting a transaction into multiple smaller ones? 👉 Transaction batching It is the process of combining multiple transfers into a single transaction to reduce fees and improve network efficiency. Despite the wording, in practice it’s not about splitting, but rather optimizing by grouping transactions together.

🤓 What is the name of the data structure linking blocks together? 👉 Hash chain It is a structure where each block contains the hash of the previous block. This is what links all blocks into a single chain, and any change in one block would break the entire sequence.

🟠 What is Bitcoin mining difficulty and why does it matter? Mining difficulty is a measure of how hard it is to find a new block in the Bitcoin network. The higher the difficulty, the more computational power miners need. ☝️ This is a built-in mechanism in Bitcoin that automatically regulates the network. Every 2016 blocks (~about once every 2 weeks), the difficulty is recalculated. If blocks are found too quickly → the difficulty increases; if too slowly → it decreases. The system aims to maintain an average block time of around 10 minutes. By the way, difficulty is directly linked to network security. The higher it is, the harder it is to attack Bitcoin. 💬 Do you track network difficulty or just the BTC price? ❤️ ECOSMiningGamebot

🧱 What type of wallet is not connected to the internet? 👉 Cold wallet It is a type of crypto wallet that is not connected to the internet, making it significantly more secure for storing funds. Such wallets are typically used for long-term storage of BTC and protection against hacks.

👾 What is the term for locking BTC in a channel on Lightning Network? 👉 Channel funding This is the process of opening a Lightning channel, where a user locks BTC in a special transaction. 💸 These funds form the basis of the channel and are used for fast and low-cost payments outside the main network.

🗓 Crypto News: Weekly Overview March 23 – 29 It’s Monday again, so here’s our weekly digest of key events in the crypto market. Let’s take a look at what happened over the past week. ▪️Bitcoin surged above $70,000 following a pause in U.S. strikes on Iran, but dropped below $67,000 by the end of the week. At the moment, BTC is trading at $66 742 per coin. ▪️The Ethereum Foundation has reassessed the role of L2 networks and plans to introduce quantum-resistant security measures by 2029. ▪️The Bitcoin miner activity index has reached an all-time low. Miner MARA sold 15,133 BTC worth $1.1 billion. 💬 We’ll be back soon with more updates – until then, stay tuned! ❤️ ECOSMiningGamebot

🔎 What transaction type encodes spending conditions in a script? 👉 P2SH (Pay-to-Script-Hash) It’s a transaction type where spending conditions are defined by a script. The address contains the script hash, while the actual conditions are revealed only when the funds are spent.

👾 What is the name of the rule requiring block timestamps to be > previous 11 blocks’ median? 👉 Median Time Past This rule requires a new block’s timestamp to be greater than the median time of the previous 11 blocks. It helps maintain proper time ordering and protects the network from manipulation.

🔎 What consensus property ensures the chain with the most accumulated work wins? 👉 Longest-chain rule This is a consensus rule where the network accepts the chain with the most accumulated work. It’s considered the “correct” chain and continues to grow.

🟠 What is Bitcoin halving? Halving is an event in which the reward to miners for mining a block is reduced by 2 times. This is part of Bitcoin’s code. Every 210,000 blocks (~once every 4 years), the network automatically reduces the issuance of new coins. 🔎 How it looked: ▪️2009 → 50 BTC per block ▪️2012 → 25 BTC ▪️2016 → 12.5 BTC ▪️2020 → 6.25 BTC ▪️2024 → 3.125 BTC (current reward) Why is this important? It’s simple! Halving reduces the rate at which new BTC appear, reduces supply, and increases scarcity. That’s why it is often associated with long-term price growth (but this is not a guarantee!). The next halving is expected around 2028 (after reaching block ~840,000). After that, the reward will decrease to 1.5625 BTC per block. Bitcoin is designed in such a way that over time it becomes more difficult to mine, and fewer new coins are created. And this is one of the reasons why BTC is called digital gold! 🚀 ❤️ ECOSMiningGamebot

🤓 What mechanism batches multiple signatures into one in Schnorr-based systems? 👉 Signature aggregation It’s a mechanism that combines multiple signatures into one (and yes, we’ve mentioned it before). In Schnorr-based systems, this reduces data size and improves transaction efficiency.

🤑 What is the Bitcoin message sent to request block headers? 👉 getheaders This is a special message in the Bitcoin protocol that a node sends to request block headers. It helps nodes synchronize and learn about new blocks in the network.

👾 What is the term for blocks that are valid but not part of the longest chain? 👉 Side chain blocks These are valid blocks that didn’t make it into the main chain because the network selected a different branch. They’re not errors – just a normal part of how the network operates.
