Your usual tools like tor, vpns (not to be used together), and portable boots like tails all on public wifi. Yadda yadda, you know.
But then there's things like no reusing conjoined wallets, mixing funds in and out and all throughout each transaction, and worrying about source of funds and how tainted they've become and that you're mixing your not so illicit comparatively funds with. Not to mention that mixers are being reverse mixed and traced as each day goes, because the more people that slip up takes away from your anon-set...
Dude there's just so much not gonna lie lol. And I'm far from the person with all the answers to this stuff... I know just enough to make sure that my personal rights to privacy are secured. I know that using Monero simplifies the more stressing part of it by not making me worry about abstract kyc and all stuff that will only get more stringent. Like let's say 5 years from now if the dude from Craigslist that bought my car last week got caught selling heroin. And they suspect he's been laundering money. So in the name of civil asset forfeiture, you have to return that amount to the state until you can prove a number of absurd things. With an opaque blockchain, those scenarios will basically just never happen...

Buying Bitcoin for cash for privacy reasons, should you still consider conjoining / mixing?

Part of the great aspect of buying BTC for cash with random people, you avoid the privacy-eroding AML/KYC requirements of buying on an exchange. Assuming you use a fresh wallet that hasn't had any prior transactions, and you don't spend from the wallet (this avoiding identification links that way), why should you bother conjoining or mixing these coins?
The way I see it:-
REASONS IN FAVOUR - In case the coins you bought had a bad history (eg, dark web, stolen), this would be masked. So, if these coins ever get sold to an exchange (where chain analysis software is used to check the history of the coins), they would be fungible, and less likely to be confiscated. - It supports the concept that the whole network is stronger and more private if everyone does mix.
REASONS NOT IN FAVOUR - It will cost for the service. - Providing you are holding with the intent not to sell to someone who will do chain analysis (an exchange), the history of your coins does not matter. - Perhaps mixed coins might be seen as tinted because they have been mixed. Inadvertently, it could be seen that you were trying to hide something.
Have I missed anything?

Privacy question concerning KYC'd Bitcoin

I'm starting to take a deeper dive into Bitcoin privacy. When I first got into Bitcoin I made multiple buys in cash, but have since moved some of said bitcoin to and from a KYC exchange. Is there some way that I can figure out what UTXOs have been associated with my KYC details and which have no links to me?
Also, can anyone point me in the direct of a clear and easy to follow tutorial for using conjoin to regain my lost privacy.

I trust nobody. I would never send my Bitcoins to someone I don't know, so how can I mix Bitcoins myself? Is it even possible to DIY?

Never used bitcoins before, no idea how much to spend to buy to use for purchases.

I'm gonna keep this short and simple!
HOW do bitcoins even work if I'm wanting to buy some to make purchases with them? Like, if I have to pay $39 for an online purchase and am able to pay with either typical money or bitcoin, do I just buy 0.0060 bitcoin (since that equals 39USD) and then that gets used in place of the $39 when I make the purchase or what? The site I'm wanting to order from doesn't convert USD to bitcoin whenever the bitcoin option is chosen for payment, so I'm confused since I have no visual idea of the amount they'd want me to pay. Which is why I'm assuming if I want to make a purchase of $39 then I'd just buy $39 worth of bitcoin?
I'm definitely not an investor (too complicated!) and cryptocurrency as a concept is pretty confusing for me, LMAO! Thanks in advance for any help!!

Lightning tx privacy

Hi All,
I could not find any thread discussing this ....
How private is a lightning transaction ? How does it compare with a regular bitcoin transaction that was "conjoined" and then sent out to another wallet ?
If one can redirect to any documentation on that matter or provide educational feedback, it would be appreciated.

Libra goals is to target those with out a bank account

Libra goals is to target those with out a bank account
I feel most of you are severely misunderstanding the goal behind Libra. I am strongly against that Facebook is creating a currency, but it would not be the end of cryptocurrency. If anything this is the preparation to drive mass adoption. Libra most likely will be a stable coin and be used either in conjunction, but in replace of traditional currency. This may be the foundation to eviscerate the current financial banking system, but create a large competitive and growing market for cryptocurrency. Facebook is almost to big to fail, but they aren't to big to compete with. This is why they are entering the crypto currency ring, if you don't see the value and take action in either building on it, or use this moment to the advantage then you'll be left behind.

Below I displayed some of my thoughts behind the value it CAN bring. We won't know for sure until their whitepaper is out. Half the world thinks bitcoin is dead, and Facebook is taking their opportunity to be re branded as "New Bitcoin" . Facebook Libra most likely will be the adoption businesses and international traders will use as means for payment. Facebook doesn't want to create another cryptocurrency or enter the financial industry as all of these companies are making credit cards etc..

They want to be the financial median. They don't want to compete in crypto, they want to conjoin and be the thing you need to join crypto.

They don't just want to topple the banks, they want to be YOUR BANK. The thing more profitable than a tech company is a financial one. They could seriously redefine banking.

Mitoshi CryptoLotto – Spreading the joy of winning, one jackpot prize at a time!

Mitoshi CryptoLotto – Spreading the joy of winning, one jackpot prize at a time!
Mitoshi is the next generation of online gaming and cryptolotteries powered by the blockchain. Our vision is to bring forth a completely fair, secure and transparent cryptolottery experience that is readily accessible to the global market. Envisioned as a truly international cryptolottery play – it will offer draws that cover the geographies of Asia, North America and Europe. Mitoshi crypolotto tokens can be purchased using fiat and crypto currencies.
Lotery is Good
Maybe your kid is sick and there are hospital bills to pay. Maybe you’ve lost your job and you’re worried about making rent. Maybe you still have a job, but it sucks, and you’d really like to spend the next 50 years lying on a beach with a mai tai in hand.
Whatever your predicament, the current estimated Powerball jackpot of $1.5 billion could fix it. Which makes us wonder — when it comes to playing the lottery, are we all just damsels in distress?
“People love to have a rescue fantasy,” human behavior expert Dr. Wendy Walsh told CNN in 2011 when the Mega Millions jackpot hit $656 million. “We have the Cinderella complex — there’s a fairy godmother who’s going to come in and save us.”
We’ve all heard the statistics. Your chances of winning the Powerball jackpot are about one in 175.2 million. You’re more likely to die from a bee sting (one in 6.1 million), be struck by lightning (one in 3 million) or have conjoined twins (one in 200,000).
But people keep playing — most likely because the thought of winning is much more fun than the thought of being attacked by a shark (one in 11.5 million).
“It doesn’t faze them because they’re in love with hope,” Walsh said.
For the 2012 fiscal year, U.S. lottery sales totaled $78 billion, according to the North American Association of State and Provincial Lotteries. More than half of us have played the lottery in the last year, although 20% of customers buy the majority of the tickets.
Part of the allure is that everyone else is doing it, said Dr. Stephen Goldbart, author of “Affluence Intelligence” and co-director of the Money, Meaning & Choices Institute.
In a Psychology Today article titled “Lottery-itis!” Goldbart noted two main reasons why people buy tickets.
Irrational or not, millions will sit around their TV and computer screens, praying that the six numbers they’re clutching will appear.
They’re optimistic that the fairy-tale ending they’ve been waiting for will come, even if it takes a little magic.
Mitoshi CryptoLotto
This is what drives Mitoshi to become a Blockchain-based online gaming and lottery platform. By using a system like this, it allows Mitoshi to run the most secure and transparent system in the world of lotteries.
Mitoshi will utilize the blockchain platform and with Ethereum smart contracts for collecting, distributing funds as well as in paying lottery sales commissions through our referral program. With smart contracts, neither winning numbers nor lottery tickets could be counterfeited. Mitoshi Cryptolotto will a decentralized community owned by the internet community – thanks to the power of the blockchain.
Mitoshi will have a widespread lineup of lottery draws. Each draw contains massive payouts for its winners. Mitoshi CryptoLotto will have a global reach, allowing anybody from around the globe to participate by the tap of a finger.

Infrastructure finance and the new economy: A Case for Tokenising

Infrastructure finance and the new economy: A Case for Tokenising
Darius Sit, Cosmochain’s advisor and Managing Partner of QCP Capital, contributed a very insightful article today to Singapore’s Business Times!
Darius Sit, Managing Partner of QCP Capital
A LARGE funding gap exists in the infrastructure space. Available funding covers only 10 per cent of sanctioned projects (about US$730 billion per annum), while 90 per cent of financing for Asian infrastructure projects comes from the public sector. To that end, private sector participation has been prescribed as a remedy for the funding shortfall — but this solution still, admittedly, also requires a supportive ecosystem to render the infrastructure assets more palatable and tradable. We believe that asset tokenisation via blockchain technology can play an important role in developing this ecosystem.
Blockchain is essentially a ledger, a copy of which is owned by every participant in a network, and into which new entries are entered only through majority consensus. This ensures transparency, security, and immutability — three crucial characteristics for investor confidence.
These characteristics — inherent to blockchain — reduce, or even completely remove, the need for intermediaries, leading to significant time and cost savings. Putting securities onto the blockchain would turn them into “tokens”: digital representations of the security that exist only on the blockchain, and in this article’s case, they would be backed by the full faith and collateral of the infrastructure assets underlying them. Tokens are the modern-day Digital Asset-Backed Security.
Financial Inclusion
The digital nature of these tokens allows for securities to be fractionalised into as small a unit as needed (for example, Bitcoin prices are to 18 decimal places). Once offered on the borderless Internet or via a smartphone, the pool of potential investors in these tokens — be it institutional, high net worth or retail — is opened up by orders of magnitude. Since tokens are globally tradable at the speed of information, they become a super-liquid investment for raising infrastructure capital across client segments, and for promoting financial inclusion. Things that have eluded traditional infrastructure financing models for a while.
Our view is that the divisibility, blockchain technology, tradability and financial inclusion aspects will make digital tokens vast, global, inclusive and liquid, as opposed to unit trusts, or other such commingled funds, which are clunky, heavily intermediated and expensive.
For these reasons, blockchain and tokenisation are increasingly seen as potentially one of the most disruptive technologies in decades. This has been especially true for venture capital fundraising. According to Business Insider, Token Generation Events (TGEs) or Initial Coin Offerings (ICOs), raised upwards of US$4 billion in 2017, an exponential jump from the US$265 million raised in 2014–16. This growth is not slowing; 2018’s figures already show year-to-date funding of US$3.4 billion.
Venture capital insiders like Venrock’s David Pakman acknowledge that a monumental shift is occurring within his own industry, particularly with respect to the democratisation of everything that technology can lay its hands on.
The same phenomenon could potentially revolutionise infrastructure funding as well.
Digitising infrastructure projects through the blockchain would enable the recording of data in great detail and with full transparency; everything from valuation and risk management mechanisms, to the various parties involved, key construction milestones, records of maintenance works, mitigation of corruption, reduction of deadweight losses and, most importantly, clarity of ownership rights.
With this, tokenisation enables the fractionalisation of ownership. Trustless and immutable blockchains track individual ownership rights and allow them to be publicly verified. Those rights become extremely transferable. Moreover, smart contracts, or self-executing contracts that run on blockchains, will reduce the time, complexity, and paperwork required for deal execution and settlement, decreasing the need for extraneous legal services and other intermediaries.
Tokens can also be used to incentivise independent parties, such as Singapore-based infrastructure consultancy company, Surbana Jurong, to rank and rate — or perhaps even validate — infrastructure asset structures in a decentralised, crowd-sourced manner. That is, instead of having rating agencies, a token-curated registry of infrastructure assets and characteristics could be validated and deployed. A token-curated registry could also be used to rank and rate infrastructure assets by having the parties who rate or vet the assets stake tokens that are bound to their own rating assessment.
In a related context, Surbana Jurong — by using its vast operating knowledge and independence, along with its validation of project time, cost and quality — has already teamed up with the ADB’s Credit Guarantee & Investment Facility to support the derisking of traditional forms of infrastructure project financing.
These factors would exponentially increase the investor base for infrastructure projects the same way it did for venture funding. It is a win-win situation; tokenisation would provide access to infrastructure projects for large segments of the private sector that are constantly hungry for quality investments but were previously unable to participate.
Paradigm Shift
The case for the tokenising infrastructure is a good one; there is clear utility towards resolving issues of instrumentation, exchanges, and liquidity for infrastructure projects. But blockchain is not, in itself, some technological panacea. There remain questions about governance, and how an overall ecosystem will manage valuation and risks well. Attempting such a paradigm shift in infrastructure financing would probably also benefit from governmental involvement in the early stages; if only to reassure about regulatory compliance, and the legal enforceability of smart-contract-based securities. This favours places with good governance, and adherence to the rule of law.
In that respect, Singapore can indeed take its global blockchain and global infrastructure financing hub aspirations a bit further by conjoining the two, especially given recent policy announcements that public bodies can now issue infrastructure project bonds.
We are ideally placed to develop this new model of financing, and it is exciting that the Centre for Asset Management Research & Investments (CAMRI) at the National University of Singapore is working with asset managers like ours to explore the securitisation of infrastructure assets on the blockchain. The success of such early moves in Singapore would be a significant first step, and would stand to benefit a wider public: democratising and opening up potentially lucrative infrastructure assets to a host of new investors, including retail, while creating new opportunities for more infrastructure capital fundraising and investment in developing nations.

QuarkChain’s sharding technology discussed in more detail

As we can read in the whitepaper, QuarkChain is a blockchain solution which tackles one of the most pressing issues in current blockchain technology: scalability. The most widely used blockchains such as Bitcoin or Ethereum reach an average tps rate (transactions per second) of around 7-10 in their current form – an issue which renders them impractical in a commercial context and thus evoked add-ons such as Lightning Network or Ethereum’s sharding technology that is currently being developed. In contrast, QuarkChain projects to reach up to 1 million tps (current testnet is above 2k tps; see It offers a two-layered architecture consisting of a root chain that is responsible for the confirmation of transaction results through processing block hashes of side chains (= shards; 2nd layer), the latter which function as the ledgers that process the actual transaction data. The project, which is run by an expert team with profound experience in data processing and scalability issues, has received massive attention and is frequently mentioned among the hottest ICOs in the first half of 2018. For a general introduction, please refer to one of the numerous reviews available on multiple platforms such as Reddit, Steemit, Medium or Youtube.
In this post, I pay closer attention to one of QuarkChain’s main features to substantially increase tps on its blockchain, namely sharding. Sharding is a well-known technology for databases to address scalability. In most simple terms, it follows the idea that data and its processing is split-up or partitioned among several hubs (e.g. servers in a centralized environment, or nodes in blockchains). If the entire database of a system is stored, accessed and processed only through a single hub, such an architecture naturally creates a bottle neck that results in significant overheads of data transactions with an increasing user base. Such bottle necks have been directly experienced for example during the CryptoKitties launch on Ethereum last year, or in a centralized environment they frequently occur in ICO whitelisting procedures in which tens of thousands of participants want to access a registration server within the first few seconds after registration opens. Obviously, the dividing of data and its processing onto several servers or nodes without the requirement that all of them have to process the entire data of the system counteracts such bottle necks. The blockchain’s overall transaction throughput is able to scale with the number of shards, and the number of shards typically increases with the expansion of the network and the number of users. Such a form of scalability is frequently referred to as horizontal scalability.
As simple as the idea of sharding is, as tricky is its implementation. We need to have a closer look at different sharding mechanisms that partition different parts of a system to increase scalability and some of the challenges related to these mechanisms.
There exist several strategies which parts of a system are exactly sharded and how. In a blockchain environment, we could, for example, split up new transactions among shards of a network, each shard only processing a portion of these transactions. New transactions are not automatically gossiped throughout the entire network, but only within the responsible shard. Once confirmed in the shard, these transactions can be then put on the blockchain. This would be an example of transaction sharding.
In contrast, we might not only split up the processing of new transactions, we might split up the entire transaction history, i.e. the state of the blockchain at a given point in time, among several nodes so that not every node has to store and process the entire state of the blockchain. This is then called state sharding.
While these two examples offer different advantages to increase overall scalability of a blockchain, there are several technical details to be considered that each bear their own security risks. One of the most important issues concerns the consensus between shards. If shards of a blockchain are able to process parts of the system independently from other shards, how can we ensure that all shards share the same state of the blockchain? And how can it be avoided, for example, that one user spends some of his balance in one shard and also spends it again in another shard (= double-spending), if the shards act independently from each other? Moreover, there is the question how to process transactions between two users that are not part of the same shard in the network (= cross-shard transactions). How can user A that is part of shard 1 interact with user B of shard 2, if the shards of the network act independently?
A sharded network therefore needs some form of consensus mechanism that ensures the overall integrity of the system and allows for interaction between its shards. One of the dilemmas involved here is that the more we increase the interconnectivity of the shards, the more data transfer between shards is required, which in turn has negative effects on the scalability. However, as pointed out above, a lack of interconnectivity endangers the integrity of the system, makes malicious attacks on the network easier, and interaction between users of different shards more difficult. In addition, it is intuitively comprehensible that a single shard of a blockchain network that consists only of a fraction of the overall hash power can be easier taken over by an adversary than a network in which all nodes share all data (= single shard take-over, cf. QuarkChain whitepaper p14). There is, therefore, a true trade-off involved between scalability and security of a blockchain network when it comes to sharding.
Based on this background, let’s review QuarkChain’s sharding architecture and see how it addresses some of the challenges outlined above. As it was already stated in the beginning, QuarkChain’s main structure consists of two layers, (1) a single root chain and (2) multiple flexible side chains (= shards; cf. Figure 4 in QuarkChain whitepaper v. 0.3.4).
Current blockchain technology usually processes two major functions at once: 1) The ledger or order book which takes over the processing of transaction data (inputs and outputs such as transferred amount, timestamp, account addresses, etc.). 2) The confirmation or validation of transactions to ensure the integrity of the system, prohibit malicious behavior such as double spending, etc. The most common mechanism to achieve this integrity is PoW (proof of work).
A main feature of QuarkChain Network is the seperation of these two major functions, the side chains processing transaction data and the root chain confirming transactions through processing only the block hashes of the side chains instead of the entire transaction data contained in them (cf. Figure 3 in QuarkChain whitepaper v. 0.3.4).
Based on this architecture, what kind of sharding technique is QuarkChain using? Since the entirety of transactions is no longer processed in a single blockchain by all nodes, instead by multiple sharded chains, the processing of transactions is split up among them and done in parallel, multiplying tps to the extent of coexisting side chains. QuarkChain therefore uses a form of transaction sharding. However, since QuarkChain’s shards are not simply dividing the processing of new transactions but are fully functioning side chains with their own respective transaction histories, QuarkChain’s structure also includes state sharding. In reality, both transaction and state sharding are integrated in QuarkChain through the clustering of nodes. Clustering is QuarkChain’s mechanism in which multiple nodes, each which process only a sub-set of side chains and/or the root chain, can join together to build a “super-full node” (cf. QuarkChain whitepaper p.24; cf. Figure 7(A) in QuarkChain whitepaper v. 0.3.4).
As long as the conjoined nodes are honest to each other and able to represent the entirety of side and root chains, they can cluster together and form such a full node. In other words, the different nodes in QuarkChain’s blockchain are not simply distributed on the independent side chains or the root chain, nodes of the different shards and the root chain are connected in such a cluster, and even more so, a single node of a cluster itself is able to participate in more than one chain (cf. Figure 7(B) in QuarkChain whitepaper v. 0.3.4).
QuarkChain’s overall architecture, while strongly sharded, simulates a conventional, unsharded blockchain in which each node processes the entirety of data. QuarkChain realizes this through clustering of multiple smaller nodes that together form a full node to validate the entire chain structure of the system.
With its 2-layer architecture, QuarkChain offers its own unique approach to simultaneously tackle 2 issues of sharding at once:
1) The interaction of otherwise independent shards to ensure the overall integrity of the network. This is mainly achieved through two mechanisms: First, the existence of a root chain on top of the shards that collects and integrates the block hashes of all shards. Second, the clustering of nodes in which all chains must be represented to cover the entire network. While the different nodes of a cluster only process parts of the system, a single full cluster covers the entire system including the two major functions of ledger and confirmation (cf. above). If my understanding is correct, in this collaboration the overall consistency of the root and side chains is first established within one such full node and then compared with other full nodes to reach consensus and integrity of QuarkChain.
2) The comparatively low requirements to successfully attack and take over shards. Since shards consist of only a small portion of the overall hash power in a system, they can be attacked and manipulated comparatively easy. However, the addition of a root chain that stores block hashes of all side chains represents a security layer that requires any attacker not only to overpower nodes of the attacked side chain, but additionally s/he has to gain control over the root chain. In order for a manipulation of a side chain to become accepted by the network, the manipulated hash history of the side chain has to be synchronized with the root chain. A very interesting feature of QuarkChain technology is its flexible attribution of hash power to the root chain. Currently, QuarkChain dictates that at least 50% of the overall hash power has to remain on the root chain. Consequently, any attacker of a side chain has to acquire an additional >25% of the overall hash power, namely >50% of the root chain’s hash power. Depending on the required security level, this amount can be adjusted. The higher the root chains hash power, the higher the overall security of the system.
One open question regards how it is decided, which node joins which of the shards and root chain. Imagine nodes having free choice to join any shard in the system. This could pose a tremendous threat to the blockchain, since malicious nodes could easily cluster together and take over a single shard. One option to solve this problem would be randomization. Nodes cannot choose the shard in which they participate but are automatically attributed to one. Usually, such randomization goes hand in hand with periodic reshuffling in order to decrease predictability of the system. However, as we have seen, QuarkChain is much more resilient against such single shard take-overs due to the root chain that has to be controlled in addition to any attack on a shard. QuarkChain is therefore able to offer a different solution. Based on a game-theoretic approach, miners can indeed choose which chain to join, however, they are incentivized to evenly distribute on the shards through varying difficulties and rewards to solve hash puzzles. This feature empowers miners to decide on themselves based on their specific hash power, which shard or root chain is most profitable to mine without the need of mining pools to remain competitive.
QuarkChain’s sharding technology comprises an entire portfolio of features and mechanisms, and this article only scratched the surface. Among the open points remain, for example, the precise functioning of cross-shard transactions, or the handling of multiple wallets belonging to different shards of the blockchain. In addition, note that sharding represents only one of QuarkChain’s core features, others being the support of off-chain transactions, EVM, cross-chain transactions, and others.
Nonetheless, I hope this article unraveled some of the intricacies surrounding sharding technology, as well as some of the issues related to it. Next to QuarkChain, other projects such as Zilliqa or OmniLedger offer sharding solutions, each with their own strengths and weaknesses. Overall, sharding in general and QuarkChain in particular offer a very promising solution to tackle the scalability of open blockchain systems.
As I am not a programmer or blockchain expert by training, I encourage CONSTRUCTIVE responses/feedback/critique and would like to further discuss the strengths and weaknesses of QuarkChain. Questions of any kind are equally welcome.

Elder Mason (Partial)
Mediator: Elder Pikku
Scribe: Sky
Council Nominations
Elder Pikku: Hey everyone. Friendly reminder that we'll be hanging out in the ts during this. Please remember to keep talking/eating/drinking/expressions of musical talent to a minimum. As usual, we will have our topics with a chance for discussion, followed by announcements and Q&A during the topics, please keep your mouths shut, and put your hand up if you wanna talk. Present today we have Elders Pikku, Pichu, and Apple and scribe Sky! The meeting is at the town hall, right by the brickton portal. First topic today is our current construction project!

Elder Pikku: We would like YOU, the wonderful people of this district to help rejuvenate Brickton. You may have noticed that there are many empty plots around.
Sid: I have noticed there are many rockbond statues
Elder Apple: Is that a problem?
Elder Pikku: To try and improve our aesthetic, we would like YOU to build on these plots.

Elder Pikku: Now that buildings no longer are demolished. It is the perfect time to build and make our district amazing! The council has been building new buildings, but you can too . We're wanting you to build too, and want to encourage you to build in an industrial style. Although some landscape/residential/ Pikku statue plots are welcomed too Any questions? Sky?
Scribe Sky: But Mason said "No Pikku statues," so what am I supposed to do?
Elder Pikku: Mason is a scrub who should not be believed. There was no elder vote to ban Pikku statues, and in fact, the majority of the council is in favour of Pikku statues.
Scribe Sky: But most of the council is in favor of the thumb [not] being finger
Elder Pikku: Mini?
Mini: So, the only guide lines are industrial style or statues? Nothing else?
Elder Pikku: No you can build other things, but we want a majority in that aesthetic. Okay moving on. You may be aware that the next Cross-District meeting is tomorrow night, and the council have decided that Brickton's topic is in regards to the Paladin powers. We are proposing a charter.
Elder Apple: To who?
Elder Pichu: The bartenders.
Elder Pikku: Which will outline which districts will recognise paladin powers, and which will maintain their current legal system with the hope of protecting existing police departments. Any questions?
Elder Pikku: Sid?
Sid: By making this proposal, are we signalling that we have some affiliation with the paladins?
Elder Pikku: Well the Paladins are in our district, so it's kinda our responsibility. We aren't trying to claim control over them. We just want to try and aid cohesion between the paladins and current police depts.
Sid: Alright. I just don't want other districts to see brickton as the source of headaches the paladins will cause or rather.
Elder Pikku: No this charter will be something all districts can use to protect themselves against paladins if they so wish.
Sid: I think it'd be wise to position ourselves such that we can claim we don't have anything to do with the paladins, should they get overzealous and bastardly.
Elder Pikku: or signal if they intend to recognise their power. We're not saying that Brickton = Paladins. We just want to try and make things easier. This charter is very one-sided.
Sid: I think we're on the same page.
Elder Pikku: Like sky says, the paladins are a third-party in this. Any other questions? Mini?
Mini: Will the paladins be independent of the police or will they be conjoined? This is what the charter will aim to indicate.
Elder Pikku: Some districts may wish the paladins to be their only form of law enforcement. Whereas others may wish to preserve their long standing depts. Also some districts may have police depts which are happy to work alongside the paladins. Any more questions or can we move on? Nope? Cool. Right topic number. 3. Council elections will be next week. which means Nominations will start after this meeting. And will stay open until Wednesday, 5pm EDT. Voting will start on Friday 5pm EDT. Ending on Saturday 5pm EDT. Positions on the council are Elder and Scribe. If you wish to nominate someone, check the post on the letterpress, and make sure they haven't already been nominated. else you've wasted your nomination. Please remember, you can campaign and ask your friends if you want to be nominated. Also please make sure you are on the Brickton census. In order for you to be able to run for a council position/nominate.
Mini: How do you get on the Brickton census?
Scribe Sky: It will be on the post.
Elder Pikku: There will be a link on the letterpress post, or ask an elder if it doesn't work for you. Any questions? Nope. Awesome. Right now is the time for announcements. Please line up behind Elder Mason if you have an announcement.
Scribe Sky: Good evening fellow Bricktonites, forty meetings ago I stood at this very podium and said that I would work with Brickton to defend it. Today with heavy heart and hand I must end that. I am formally resigning from the BPD. As the work has gotten too much for me and I have not been having fun. It has been fun and I would like to thank everyone for their support.

Scribe Sky: You all allowed the BPD to be good as it has been. Please I have a bit more to say. As for the next head of police I would suggest Sheriff Stephen of [Mainstreet]. Since he is capable of long distance managment and loves policeing. At the end of the day it is the council’s decision. So yeah. Flut Butt?
Flutter: Can we have Jeff as our new constable I don't trust people from MS?
Scribe Sky: I don't trust babies. You know what...
Elder Pikku: Can we really trust MS after they stole our Lord?
Scribe Sky: You know what if you feel that salty about Roamin. Why not just move to MS?
Elder Pikku: Because Brickton is better than MS.
Scribe Sky: Is it?
Elder Pikku: Yes.
Scribe Sky: But anyway.
Scribe Sky: No Elitism bye.
Elder Pikku: I think it's time to move on to the next announcement~
Mini: May I?
Elder Pikku: Yup.
Mini: Hello Brickton.
Elder Pikku: Hi!
Mini: About a week ago, I moved into brickton for the first time. The only announcement I have to make, is I hope to enjoy the time I have in Brickton, and I hope I can learn and have fun with all of you.

Elder Pikku: Alright, time for Q&A. Raise ya hands. Clover?
Clover: How did you become a hangover?
Elder Pikku: don't know what you mean~ Rex?
Rex: How much wood can a woodchuck chuck if a woodchuck could chuck wood?
Elder Pikku: at least 3. Computer? Casey?
Casey: Yes?
Elder Pikku: You raised your hand?
Casey: none
Elder Pikku: Computer then?
Computer: With U Realms live starting at 5:00 EST can we move the meeting time earlier since it's still going on.
Elder Apple: My Immersion.
Elder Pikku: We may try some different times. I think as we've seen tonight a lot of people can make it regardless, but we will bring it up with the council. So keep an eye on the letterpress to see if we decide to change the time. Sky?
Scribe Sky: What do you think of the danger that Pikku brings to Brickton?
Elder Pikku: None Pikku's awesome. Rex?
Rex: When are we getting a guild plot?
Elder Pikku: idk man. Any others? Apple?
Elder Apple: Hi, I'm Citrines
Elder Pikku: Hi Citrines. Anymore questions? Mini?
Mini: Does Brickton currently have any plans for events now?
Elder Pikku: OH!
Elder Pikku: I'll answer you question in a second.
Scribe Sky: As President of Brickton, [A new nation has appeared in the lake current reports are spotty but as of currently we do not recognize them since no lord recognizes them]
Elder Pikku: Mini we don't have any events planned right now, but soon hopefully.
Mini: Okay.
Elder Pikku: Sid you had a question?
Sid: Why do we have a bitcoin in our ceiling?
Elder Pikku: It's a "B" for "Blocktatorship.
[So elitist]
Elder Pikku: Rex?
Rex: Are we celebrating anything for a one year anniversary?
Elder Pikku: Ummm,
Scribe Sky: Not at this moment.
Elder Pikku: We will bring that up in the council discussions right away! Anyone have any ideas for the anniversary?
Rex: I have something planned.
Elder Pikku: Oh Rex?
Rex: It would be held on the day brickton had its first meeting July 27th.
Elder Pikku: Ooh cool.
Rex: Thats all really....
Elder Pikku: Alright, if we have no more questions. Then meeting over!
Elder Mason: Drive safely!

Bitcoin philosophical musings and pressures 7 years in [drifted from: txrate, forking, etc] | grarpamp | Jul 07 2015

grarpamp on Jul 07 2015:
Then again maybe I am missing the key reasoning for this fork.
People often miss the fundamental reasons Bitcoin exists,
the various conjoined ethos behind its creation. This is to be
expected, it's so far ouside any thinking or life process they've
ever had to do or been exposed to. It's also partly why figuring
out what to do or code or adopt, is hard. And certainly not made
any easier by the long term need and the current value at stake.
Creating a system in which a Botswanan can give a few bits
of their impoverished wages to their friend in Mumbai without
it being gated, permitted, hierarchied, middlemanned, taxed,
tracked, stolen and feed-upon until pointless... this simply
doesn't compute for these people. Their school of thought is
centralization, profit, control and oppression. So of course they
see txrate ramming up against an artificial wall as perfectly fine,
it enables and perpetuates their legacy ways.
Regardless of whichever technical way the various walls are torn down,
what's important is that they are. And that those who are thinking
outside the box do, and continue to, take time to school these
legacy people such that they might someday become enlightened
and join the ethos.
Otherwise might as well work for ICBC, JPMC, HSBC, BNP, MUFG
and your favorite government. Probably not as much fun though.
