Bitcoin Q&A: Price and hashpower metrics

What is the significance of key metrics like price in the course material? Are price and hashpower correlated? Bitcoin's hashrate seemed to drop by +30% recently. Why? Is the exchange rate between fiat and bitcoin always determined by supply and demand? CORRECTION: At 5:25 I said that Laszlo Hanyecz paid ten thousand bitcoin for Dominos pizza in 2010. It was actually Papa John's pizza. These questions are from the second, third, and fourth sessions of MOOC 12, which took place on September 19th, September 27th, and October 4th 2019, respectively.

Grin 101 – What is Grin and How it Works

One of the biggest challenges for the adoption of bitcoin as a global currency is scalability. There have been several attempts at solving this, among others: The implementation of SegWit (malleability fix but allows for scaling through layer 2 solutions like Lightning Network) Changing block sizes (like the BCH fork) New currencies that use different protocols including the one of interest today called Grin So, what is Grin, how does it work and why is it interesting? What is Grin? Grin is a community-supported implementation of the MimbleWimble protocol. The MimbleWimble protocol seeks to accomplish 3 main things: Ensure privacy by using zero-knowledge proofs Keeping a small blockchain by registering less information on the blocks Have fast transaction verification processes Grin seeks to accomplish scalability and privacy by having no addresses and no amounts stored on the blockchain. How does it work? MimbleWimble relies on Confidential Transactions and CoinJoin to keep information about the transaction private. Confidential transactions use blinding factors to hide the amounts in a transaction, and nodes only need to verify that no new money is being created. An example of how blinding factors work in cryptography can be conceptualized through the following sample equations: 1 + 2 = 3, or 1 + 2 – 3 = 0 Adding a blinding factor would look something like multiplying every value by 5: 1×5 + 2×5 = 3×5, or 1×5 + 2×5 – 3×5 = 0 Secretly multiplying every original value by 5 does not change the fact that the equation is balanced (nodes verifying the process will see 5 + 10 = 15 and confirm no new money was created) but will obscure the original values. This zero-knowledge proof works when both parties involved in the transaction communicating directly: Both parties agree on the amount to be transferred Sender chooses inputs which will add up to the amount that was agreed upon. Sender then choses blinding factors for the transaction and adds them together before sending to receiver Adding together all the blinding factors for every input in the transaction proves you own them Receiver picks the blinding factors for the output of the transaction and adds them together and sends back to sender Knowing the blinding factor for a given output allows you to spend it Why Does Grin, Which is Based on MimbleWimble, Matter? Grin claims to follow the original spirit of Bitcoin by being a community-supported project and remaining decentralized and somewhat ASIC mining resistant. It is a one of a kind coin; its closest competitor is BEAM, another implementation of the MimbleWimble protocol but under a more centralized approach. Right now, Grin can be mined in PCs, and it has the potential to be a truly private, decentralized, and scalable coin.

Bitcoin’s SegWit registers ATH of 57.18%, but transaction fees refuse to drop

On 16 September, Segregated Witness [SegWit] reached a major milestone after reports suggested that Bitcoin transactions on the SegWit protocol hit an all-time high of 50.7 percent. The protocol was first developed by Pieter Wuille back in December 2015, with an intent to reduce processing fees and facilitate faster transactions. Now, according to new data, […] The post Bitcoin’s SegWit registers ATH of 57.18%, but transaction fees refuse to drop appeared first on AMBCrypto.

Bitcoin Will Slowly Rise Overtime Without Quick Influence By Scalability – BitMEX Research

Since the crypto winter ended a few months ago, numerous traders, investors, and analysts have fielded theories suggesting that Bitcoin could make a serious jumpstart and head for the moon pretty fast. However, according to BitMEX, that’s unlikely to happen.  According to a recent study conducted by BitMEX Research, the analytics arm of the BitMEX exchange, Bitcoin will only grow slowly over time as opposed to a sudden movement that many have been expecting for months.  What Commentators Say  Many commentators have been quoted as saying that the introduction of various new Bitcoin-focused products would lead up to a sharp movement in the BTC market. Even more, people believe that the increased interest in Bitcoin by big market players from various economic sectors would be a huge force behind the said movement.  According to others, the advancement made in improving the scalability of the Bitcoin network is of great importance and could contribute to the growth. For example, the Lightning Network will improve Bitcoin’s usability and adoption even in the lower quarters of average users.  Improve Usage Of The Lightning Network In its report, BitMEX taps into the possible impact of the Lightning Network and other solutions developed to improve BTC’s scalability. However, according to BitMEX, these technologies, especially SegWit and Schnorr signatures, need to work together to bring about an overall impact on the Bitcoin market.  Image Via BitMEX Research This argument backs up that earlier made by Sam Mow, the CEO of Blockstream, that people need to use the Lightning Network more expansively. However, he noted that there’s no magic trick to jumpstart the growth of the network. It has to grow organically to make a long-term impact.  Long-term Focus Currently, Bitcoin seems to be having a moment of uncertainty. It dropped below $8,000 over the weekend. Analysts are now looking into the long-term prospects with a strong focus on the upcoming Bitcoin network reward halving expected to occur in 2020.

Bank of Canada Exploring Possibility of Launching a Digital Currency

Bank of Canada, the Canadian central bank, is exploring the possibility of launching a digital currency that would replace cash and track how people spend their money.

Brave Blockchain and Privacy Browser Scores 8 Million Active Monthly Users

Blockchain-powered privacy web browser, Brave, has just announced in an official blog post that the browser now has 8 million active users who use it monthly and a daily user mark of 2.8 million. The platform’s growth has been quite commendable and is slowly increasing in popularity, gearing up its head to compete with other bigger browsers. The Brave platform now also has 290,000 Brave Verified Publishers, who earn Brave’s Basic Attention Tokens (BAT) as payments for the content they produce and make available. Of this number, the announcement states that 15,000 are Twitch streamers with 33,000 website publishers and creators and a whopping 200,000 content creators on YouTube. Two months ago, Brave began allowing Twitter users to tip other accounts that post interesting content, using BAT. Since inception, 28,000 users have now signed up for this service and are free to tip and receive as well. The Brave team is heavily focused on putting control in the hands of content creators and eliminating the middlemen as much as possible. For a long time, major ad services companies like Google and Facebook, have not only been profiting too much off users’ contents but seem to unnecessarily tracking ad and user activity. Since the Brave platform is powered by blockchain technology, there is little to no chance that there will be any unnecessary tracking. Brave also incentivizes its users to watch ads on the platform and pays these viewers in BAT. The Brave Ads platform is an opt-in service that was officially launched back in April and according to design, users are paid 70% of revenue from the ads just for viewing them. Today, there have been 385 successful campaigns on the platform. Furthermore, Brave also reports that its platform engagement has hit an impressive 14% click-through rate, much higher than the industry average of 2%.
