Instead, cryptocurrencies are created and maintained on distributed ledgers, or blockchains. This democratization of control allows blockchain networks to act far more efficiently than traditional organizations and governments, which employ expensive and time-consuming top-down leadership models. The greatest advantage of cryptocurrencies is that their transactions are stored on ‘immutable’ blockchains. Immutable means that something can never be altered. The transactions that enter a blockchain, therefore, can never be altered or tampered with. This makes both double-spending and counterfeiting almost impossible – a regular problem with fiat currencies such as the US dollar. Bitcoin, blockchain, and cryptocurrencies burst onto the world stage in 2008, when the online posting of a pseudonymous white paper envisioned a new way to transfer value over the internet.1 In the decade-plus since, the crypto asset market has gone through all the classic phases of a disruptive technology: massive bull markets and crushing pullbacks, periods of euphoria and moments of despair, FOMO (fear of missing out), fear, and everything in between Blockchain technology underlies all cryptocurrencies and cryptocurrency transactions. Blockchain is a shared, immutable digital ledger, enabling the recording of transactions and the tracking of assets within a business network and providing a single source of truth. The key benefit of blockchain lies in its ability to provide security, transparency and trust without relying on traditional intermediaries, such as banks or other third parties. Its design reduces the risk of fraud and errors, making it especially valuable in industries where secure transactions are critical, including finance and healthcare. In addition, blockchain helps businesses improve efficiency and reduce costs by streamlining processes and enhancing accountability. **Frequently asked questions:** **Do I have to finish the book to attend?** Not at all. If you plan to read or have read it, that’s great; if you haven’t touched it, you’re still more than welcome to join. Come and meet like-minded people and connect over the topic as well as the book. **How can I contribute to the discussion if I haven’t read the book?** The book is simply a conversation starter - our discussions often branch out into related themes, personal experiences and broader topics of interest. Our gathering is more about socialising and engaging in decent conversations with book lovers, rather than a formal seminar. **Can I also discuss my own fav book or the book I recently read?** Absolutely! Our gatherings are all about open conversations, and we’d love to hear your thoughts on any book that’s been captivating to you. **Is this group open to everyone?** Yes - this is a friendly and inclusive group, welcoming everyone regardless of gender, sexuality, or background. The event is designed to make it easy to meet and connect with fellow book lovers in our community. **What if I'm shy about speaking in front of the group?** No pressure! You're welcome to participate in the way that feels most comfortable for you. Whether you share your views or just listen, your presence is valued. A lot of people come alone - so don't be shy!!

Monday December 29th at 6PM we'll be meeting up dinner at the Pies & Pints at Easton. Feel free to bring guests. Sandwiches run about $15 and large pizzas run $20-30.

In this local meeting, you will discover knowledge that you can use to get over the past. The key to improving your personal motivation, self-confidence, and happiness is to get over your painful memories. When you become free of your past, you will be free from stress, anger, anxiety and depression. Studies show that negative emotions can affect your health. By being free of negative emotions, believe it or not, you will most likely even look younger, feel more energetic, and become healthier! Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is brought to you by the Dianetics and Scientology life improvement center.
