Let's explore #Bitcoin's UTXO (Unspent Transaction Output) model and how it differs from the traditional account-based model. We'll dive into some code examples to help you better understand the concept. 💡🔗 #UTXO #Bitcoin #DontTrustVerify In the UTXO model, transactions consume 'unspent outputs' from previous transactions as inputs, and create new outputs. This is different from account-based models where balances are updated with each transaction. Example: Alice sends 1 BTC to Bob and has a 2 BTC UTXO. Transaction: Input: Alice's 2 BTC UTXO Outputs: 1 BTC to Bob, 1 BTC change back to Alice The input UTXO is now 'spent' and can't be used again. For better understanding here is a python code example: This code snippet completes the transaction, assigning the outputs to Bob and Alice as new UTXOs. This concept provides more privacy and better scalability. By tracking unspent expenses instead of account balances, the Bitcoin network can verify transactions without needing to know the entire transaction history. #Privacy #Scalability In my next thread, we'll take a closer look at the implementation details of UTXO set management, validation, and transaction generation in the source code. #UTXO #Bitcoin #DontTrustVerify

Let's dive into the 21 million cap of #Bitcoin   ! This crucial aspect of Bitcoin's scarcity is enforced by the code itself, specifically through the block reward halving mechanism. Let's have a loo on code level. The block reward started at 50 BTC per block and halves every 210000 blocks. This halving process continues until the reward becomes negligible, ultimately reaching the 21 million cap. This is defined by the following line of code: To calculate the block reward at a given block height, the code uses this function: This function calculates the number of halvings by dividing the current block nHeight by the halving interval (210,000). It then initializes the nSubsidy as 50 BTC and reduces it by half for each halving that has occurred. When halvings reach 64, the reward becomes zero. The sum of this geometric series (50 + 25 + 12.5 + ...) converges to 100, which, when multiplied by the 210,000 block interval, results in the 21 million cap: (50 + 25 + 12.5 + ...) * 210,000 ≈ 21,000,000 BTC By enforcing the 21 million cap through code, #Bitcoin    ensures its scarcity, creating a predictable supply that mimics the characteristics of precious metals like gold. This makes it a desirable asset and a hedge against inflation. #Bitcoin    #21million #DontTrustVerify

Manager food for thought: 'What you can't measure doesn't exist.' 🤔 While data-driven approaches are essential, let's remember that intangible factors like creativity, empathy, and teamwork also play a crucial role in our success. #ThoughtOfTheDay #Leadership

EU tackles greenwashing with common criteria for eco-claims 🌍🍃 This initiative will provide clarity to consumers and support truly sustainable businesses. I think this paper brings the topic of #bitcoin    mining energy usage back to the table. Although over 50% of mining is already done with clean energy, it is important to expand this further. Let's work together for a sustainable future! 💡🌱

Consumer protection: enabling sustainable choices and ending greenwashing

Today, the Commission is proposing common criteria against greenwashing and misleading environmental claims.

Don't trust, verify! 🔎 One of the core principles in the Bitcoin community is to validate transactions and information independently. By running a full node or verifying code, you're taking charge of your financial sovereignty and contributing to a decentralized and secure network. Be an active part of the ecosystem! 💪
