🧐 What converts data into a unique hash?

👉 Hash Function

A hash function is a cryptographic algorithm that converts any input data into a fixed-length hash. In Bitcoin, hash functions are used to secure transactions, link blocks together, and power the mining process.

Every Bitcoin block depends on hash functions — and your next XP in ECOS GAME is just one login away.

🤓 What is rearranging blockchain history called?

👉 Chain Reorganization

A chain reorganization, or "reorg", happens when the blockchain temporarily switches from one chain of blocks to another that becomes longer and is accepted by the network. This is a normal part of Bitcoin’s consensus mechanism and helps ensure that all nodes eventually agree on the same blockchain.

Sometimes blockchains reorganize to find the valid chain — but finding your daily XP in ECOS GAME is much easier.

🗓 Crypto News: Weekly Overview
June 29 – July 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.

🔹 Nearly half of Bitcoin’s circulating supply is currently being held at a loss. Researchers estimate that most of these coins belong to long-term holders, who continue to hold their BTC despite being underwater.

🔹 Bitcoin recorded its worst monthly performance in four years. During June, BTC fell by around 20%, dropping below $60,000 and posting its steepest monthly decline since 2022.

🔹 Metaplanet purchased 2,823 BTC in Q2, increasing its total holdings to 43,000 BTC. The Japanese investment company also generated $10.95 million in revenue through its Bitcoin Income Generation program, which uses Bitcoin options.

🔹 JPMorgan warns that Strategy’s Bitcoin reserve sale mechanism introduces "two-sided risk." According to the bank’s analysts, Strategy is now acting as both a buyer and a seller of Bitcoin, increasing uncertainty and potentially adding to market volatility.

🔹 Vitalik Buterin shared Ethereum’s updated development roadmap. The Ethereum co-founder summarized the outcomes of the network researchers' meeting in Berlin and outlined the next steps for the ecosystem.

🚀 We’ll be back soon with more updates — until then, stay tuned!

🫶 What is the process of building a new block called?

👉 Block Assembly

Block Assembly is the process of building a new Bitcoin block. During this stage, a miner:

⚡️ Selects unconfirmed transactions from the mempool
✅ Verifies those transactions
🧩 Assembles them into a candidate block before mining begins

Every new block starts with Block Assembly – and your next XP starts with a quick visit to ECOS GAME.

🤑 What is mining a block with no regular transactions called?

👉 Empty Block Mining

Empty block mining is the practice of mining a Bitcoin block that contains only the coinbase transaction and no regular user transactions.

Miners may do this to start mining a new block as quickly as possible while the full list of transactions is still being processed.

Remember that collecting your daily XP in ECOS GAME is always a smart move.

🗓 Crypto News: Weekly Overview
July 6 – 13

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.

🔹 The United States is officially embracing crypto. SEC Chairman Paul Atkins confirmed that the agency is carrying out President Trump's initiative to make the U.S. the "crypto capital of the world." The SEC has released its 2026 regulatory roadmap, signaling a shift from enforcement-driven actions toward clearer rules for the digital asset industry.

🔹 Earlier this week, Strategy sold 3,588 BTC worth approximately $226 million. However, JPMorgan analysts believe that these periodic Bitcoin sales are not the market's biggest concern. According to The Block, the real long-term risk lies in the rapid development of private blockchain infrastructure.

🔹 Leading U.S. Bitcoin mining company MARA Holdings announced plans to invest up to $600 million in a new facility dedicated to both AI computing and Bitcoin mining.

🔹 The crypto market has now posted negative returns for three consecutive quarters, marking its longest losing streak since 2022. Analysts believe this could indicate that the market is approaching a bottom, potentially setting the stage for a future recovery.

We'll be back soon with more updates – until then, stay tuned!
