  1. Now that you're so rich do you still hang out with regular folks? :-)
  2. "Bitcoin was very innovative them" -> then Generally speaking, since this is a "for dummies" post, it's ok but there are some things that bother me. If it was a tech-article about the XRP (Ledger) I would address them here but overall since this is an introduction, it's ok... The use of a "pre-mined" concept means that someone actually had to mine them at a certain time(s). Obviously, this not the case when speaking about XRP. Just out of curiosity, why do you use capital letter(s) on certain words? :-) Here's what Ripple's CTO David Schwartz had to say about XRP (on quora). It's not for dummies but it gives you an overall idea. What are some XRP details not known to most individuals? "XRP is a cryptocurrency that trades on a public, permissionless blockchain. Anyone can run a server or validator and participate in the network and submit transactions. No XRP Ledger transaction has even been censored, suppressed, or discriminated against and the ledger’s design makes this much more difficult than it is on other blockchains. The XRP Ledger’s rules are enforced by all participants and they can only be changed by participants who choose to run code with different rules. Ripple is a company with over 300 full-time employees and headquartered in San Francisco. Ripple owns a lot of XRP. Ripple is working on using XRP to settle international payments between financial institutions. The XRP Ledger uses a distributed agreement protocol to make forward progress. Network participants collectively decide which transactions to process in the current group and which to defer to the next group (typically processed four seconds later). Amazingly, this is the only thing needed to preserve consensus. Why? If a transaction is invalid, no honest participant will ever agree to execute it and no honest participant will ever agree that it executed. If a transaction is perfect and network connectivity is working, no honest participant will ever disagree to execute it and all honest participants will automatically agree on what it did when it executed. One participants agree on which transactions to execute in the current round, they can use the system’s known rules to sort the transactions, execute them, see which transactions succeed, and will automatically agree on the results since they’re all following the same rules. All that leaves are “wobblers”, that is, transactions that honest people can disagree over. That might include transactions received very late in the consensus process, transactions that are part of a double spend attempt, or so on. All that is needed for wobblers is for the network to agree to either try to execute the transaction immediately or to defer it to the next group of transactions (if it’s valid at that time). The XRP Ledger’s distributed agreement protocol, called “consensus”, has a number of advantages over proof of work. It’s much faster, allow near-certain confirmation of a transaction in less than six seconds. Proof of work typically takes several minutes and often hours. It’s much cheaper. Proof of work can cost millions of dollars a day. It’s much more censorship resistant. Each miner has complete freedom to put whatever transactions they want in the blocks they mine. There is no dictator for blocks in the XRP Ledger. It’s more decentralizing. Miners tend to have similar properties because they need cheap power and access to hardware. This has concentrated mining in particular countries. Validation can be done by anyone at low cost on the XRP Ledger. The XRP Ledger can handle around 1,500 transactions per second. Typical transaction fees translate to less than a hundredth of a penny. The XRP Ledger has an enormous number of built in features, mostly aimed at using XRP as a payment asset. These include: You can announce a receiving address for people to send funds to and you can later change the key that protects those funds without changing the receiving address. You can designate accounts that have signing authority over your account in sophisticated multisignature scheme. Signers can manage their own credentials and you can change who your signers are, all without having to touch your funds or change your receiving address. The XRP Ledger has a large number of features around lending, credit, asset exchange, and cross-currency payments. There is support for off-ledger scaling with escrows and payment channels. I’m sure I’m leaving a lot of stuff out, but that’s all that I can think of right now. "
  3. Great initiative CaligulazBaby and cheers to PatriciaC!
  4. Multi-signature accounts: https://xrpl.org/multi-signing.html https://xrpl.org/set-up-multi-signing.html https://xrpl.org/send-a-multi-signed-transaction.html Don't keep your crypto on the exchanges as per "not your keys, not your money"... And like you said, we love HW-wallets too!

  6. Last week I wrote this on Ripple subreddit: "Your moment of zen: it's soon 2020 and the banking world is still partying like it's 1970s. Tomorrow and day after tomorrow the banks will still not process your transactions that you submitted today. Maybe on Friday if you get lucky, most likely on Monday and if you did a cross-border Tx somewhere next week. Meanwhile on XRP Ledger, things get settled in about 4 seconds..." That's your SWIFT in action folks, in the year 2020 and beyond. So, let's see how long it takes to send&process data from Mars to Earth using real examples as explained here and here. Not only to send the data but the whole process: making the measurement on the Martian surface with instrument(s) on-board the Curiosity rover saving the data inside the memory on-board the Curiosity rover sending the data to one of the NASA orbiters dumping the data from the NASA satellite in an orbit around Mars to the ground station(s) on Earth that are visible at the time of data dump (remember, Earth is spinning kids, Mars is spinning, satellites are spinning around Mars, things change just like validators that can disappear from time to time due to whatever reason) merging the data from one or several ground station that are located in different geo-locations (USA, Australia, Russia, etc.) to one raw file making calibrated files analyzing the data iterating with other team members to make sure that what you have is 100% correct talking to communication team at NASA iterating with them several times posting it online If you clicked on the two links above (from the NY-times) and you compare it with the info on the NASA website you will see that it only took them approx. 24h to do ALL this. On top of that, the measurement was done during the weekend and even then NASA is apparently working unlike, for example, oh let's say, the banks. Meanwhile it's soon 2020 and the banking world is still partying like it's 1970s. This is your moment of zen. See you next year, HO HO HODL! Bonus , Asheesh Birla agrees , from https://seekingalpha.com/article/4297861-executive-interview-series-asheesh-birla-ripple-svp-of-product: "“I can watch streaming video from Mars, but I can’t send a payment to India instantly and cost-effectively,” said Asheesh Birla. The world’s payment infrastructures were never modernized for the Internet age, Birla explained, which is why moving money across borders is slow, unreliable, and expensive."

  10. https://www.ecb.europa.eu/paym/intro/publications/pdf/ecb.mipinfocus191217.en.pdf Executive summary The ongoing digitalisation of the economy represents a major challenge for the payments ecosystem, requiring that a balance be struck between allowing a certain degree of privacy in electronic payments and ensuring compliance with regulations aimed at tackling money laundering and the financing of terrorism (AML/CFT regulations). Under the coordination of the ECB, the European System of Central Banks (ESCB) has established a proof of concept for anonymity in digital cash – referred to here as “central bank digital currency” (CBDC).That proof of concept is part of the ESCB’s ongoing technical research on CBDC and the aim is to contribute to the broader discussion on the topic. The work carried out is not geared towards practical implementation and does not imply any decision to proceed with CBDC. The ECB will continue to analyse CBDC with a view to exploring the benefits of new technologies for European citizens and in order to be ready to act should the need arise in future. The prospect of central bank initiatives, however, should neither discourage nor crowd out private market-led solutions for fast and efficient retail payments in the euro area. The proof of concept drawn up by the ESCB demonstrates that it is possible to construct a simplified CBDC payment system that allows users some degree of privacy for lower-value transactions, while still ensuring that higher-value transactions are subject to mandatory AML/CFT checks.That proof of concept boasts several novel features developed by the ESCB’s EUROchain research network (with the support of Accenture and R3) using distributed ledger technology (DLT). It provides a digitalisation solution for AML/CFT compliance procedures whereby a user’s identity and transaction history cannot be seen by the central bank or intermediaries other than that chosen by the user. The enforcement of limits on anonymous electronic transactions is automated, and additional checks are delegated to an AML authority. This is achieved using “anonymity vouchers”, which allow users to anonymously transfer a limited amount of CBDC over a defined period of time.Although there is no immediate need to take concrete steps towards the issuance of CBDC in the euro area, the proof of concept will be instrumental in any assessment of (i) how CBDC could work in practice and (ii) how the specific technical features of such an initiative will affect its potential implications for the economy. Lessons learned and way forward The proof of concept shows that it is possible, using the Corda platform, to build a simplified CBDC payment system that safeguards users’ privacy for lower-value tr ansactions, while still ensuring that higher-value transactions are subject to mandatory AML/CFT checks. However, that proof of concept also highlights a number of areas where there is room for improvement. Reducing the amount of information visible to parties not involved in the transaction: one challenge that would need to be addressed is the impact of the transaction validation mechanism on confidentiality. In the proof of concept, intermediaries validating a CBDC transaction need to look at information on past transactions of the CBDC units being transferred, all the way back to the moment when they were first issued. Notwithstanding the data segregation model of Corda, a participant can therefore build a knowledge graph based on information collected from the CBDC units it receives over time. This means that details of past transactions can be seen by new holders’ intermediaries that were not involved in those transactions. Nevertheless, no intermediary has a full overview of all network activities at any given point in time. The central bank knows the amount that is currently in circulation, but only obtains information on individual CBDC units and the pseudonyms of their holders when those units are redeemed. To some extent, this challenge can be addressed through the process of trimming the history of a state –referred to as “chain snipping”. This is a technical procedure whereby an intermediary initiates the redemption of all CBDC units held in the accounts of its users and triggers the issuance of the relevant amount of CBDC for each user. By resetting the history of a user’s units, an intermediary reduces the amount of information that is visible to other participants. However, that has no impact on the user’s privacy vis-à-vis the central bank, which still receives all information carried by redeemed units. Users’ ability to access or spend CBDC balances when the intermediary is unavailable: the proof of concept could be enhanced to include an option allowing users to hold CBDC units and initiate transactions independently of their original intermediary. In the present version of the prototype, a technical failure on the part of the original intermediary will result in its users being unable to access their CBDC balance or spend (and, in some cases, receive) units. This issue could be mitigated by allowing users to sign transactions through keys stored in their own device (such as a mobile phone wallet) and enabling other intermediaries than the original one to access the user’s “back-up” CBDC units. Shorn of its custodial services, an intermediary would, in such a situation, be more akin to a transaction gateway, conducting services like “know your customer” processes. Exploring anonymity in central bank digital currencies10Limiting the number of accounts per intermediary: t he current prototype does not include a mechanism ensuring that users can only have one account with one intermediary. The decentralised implementation of such a solution is another possible area for investigation. Adding privacy-enhancing techniques: privacy could be further enhanced by using mechanisms such as rotating public keys, zero-knowledge proof and enclave computing. Using rotating keys, which would involve users generating new pseudonyms on a regular basis, would limit nodes’ ability to link transactions to individual users, since users would be using various different pseudonyms over time. At the same time, intermediaries would still be aware of all transactions initiated and received by their respective clients, and the AML authority would know the real identities of the payer and the payee whenever transactions without anonymity vouchers were sent for approval. Interoperability with an RTGS system: moreover, the current proof of concept does not cover the link between the present prototype and the RTGS system. Avalidation procedure at that juncture would involve several additional steps. For instance, the payment would need to be confirmed before the central bank issued or redeemed CBDC units. Practical functioning of the prototype: finally, the proof of concept focuses on concept and design rather than the functioning of the prototype and the efficiency of the prototype. Scalability of the prototype was for example not analysed.
