The People's Bank of China (PBoC) has issued a new warning alleging that cryptocurrency projects are misusing its name in an effort to defraud investors.
Issued on 15th June, the announcement sought to make public the issue, while clarifying that the central bank has not issued any digital currency or authorized any institution to do so. Adding to that, it reiterated that there is no digital currency marketing team at the PBoC, nor does the institution consider applications of the technology legal tender.
The PBoC went so far as to warn Chinese consumers that so-called "digital currencies issued by PBoC" could be a part of a pyramid scheme.
The PBoC concluded that:
Quote:"We call on the public to establish a correct concept of money, cherish the RMB and maintain a normal circulation of RMB together."
In broader context, the comments are the latest that find China's central bank stepping up its regulation of the cryptocurrency sector. (Earlier this year, it sought to aggressively police domestic exchanges amid a surge in the bitcoin price.)
Lending plausibility to the scams, they also come at a time when the PBoC is actively increasing its blockchain research and development, and former representatives of the institution have begun to up about the technology and its potential impact.

---
Their word of, "We call on the public to establish a correct concept of money, cherish the RMB and maintain a normal circulation of RMB together."
It seems the China's government actually getting nervous with the popularity of digital currency will replace their fiat?

The government will soon take a call on whether India should regulate virtual currencies such as bitcoins—a cryptocurrency used as a digital mode of payment.

A committee comprising officials from finance ministry, NITI Aayog, ministry of information technology, State Bank of India and the Reserve Bank of India (RBI) is giving final touches to a report on the way forward for virtual currencies in India and whether or not to legalise or regulate them.

The panel is also examining the existing international framework on virtual currencies and will suggest measures on consumer protection and prevent money laundering.

"We have had five meetings and have consulted all ministries, public, stakeholders (exchanges such as Zebpay and Unocoin). We will submit the report by July-end," a senior government official told Moneycontrol.

The crucial task for the committee is to fix the accountability for the transactions carried out through virtual currencies and a body needs to regulate them, the official explained.

“SEBI (Securities and Exchange Board of India) can be asked to regulate virtual currencies as transactions are currently done through unregulated exchanges. RBI may step in if the government plans to regulate them or accept them as currency,” the official said.

Currently, India does not have any monitoring mechanism for virtual currencies. Most countries are yet to determine the legality of bitcoin--the most commonly used virtual currency.

Countries like the US, European Union, Australia have indirectly given nod to the legal usage of bitcoins by introducing regulatory mechanism, while Russia and Iceland have banned them.

The government panel is said to have exploring the possibility of various options. One of them being hiring an agency that would monitor the trading guidelines and finalise the laws governing virtual currencies.

"We may monitor these currencies for some time and then see how it progresses. It can then be concluded if at all there is a need for a regulator,” the official said.

However, chances of legalising currencies like bitcoins are very bleak, the official said. On the other hand, banning bitcoins is not easy. Simply because one doesn't know who is trading or operating it, he explained.

A comprehensive framework for regulating such currency transactions is likely to take long time as the legal structure doesn't exist to deal with them.

Time and again, the RBI has warned traders of the perils of using virtual currencies. In 2013, the apex bank had cautioned the users, holders and traders of virtual currencies, including bitcoins, about the potential financial, operational, legal, customer protection and security related risks that they are exposing themselves to.

Such currencies are stored in electronic wallets and are prone to losses arising out of hacking, loss of password, compromise of access credentials, and malware attack, RBI had said.

“...VCs, including Bitcoins, are being used for illicit and illegal activities in several jurisdictions. The absence of information of counterparties in such peer-to-peer anonymous/ pseudonymous systems could subject the users to unintentional breaches of anti-money laundering and combating the financing of terrorism (AML/CFT) laws,” it had then warned.

The government also echoed similar views recently.

“RBI has cautioned the users, holders and traders of Virtual Currencies(VCs), including Bitcoins about the potential financial, operational, legal customer protection and security related risks that they are exposing themselves to. The creation, trading or usage of VCs including Bitcoins, as a medium for payment have not been authorised by the RBI,” Arjun Ram Meghwal, minister of state for finance, had told Lok Sabha in a written reply in February this year.

What is a UASF?
UASF stands for User Activated Soft Fork. It’s a mechanism where the activation time of a soft fork occurs on a specified date enforced by full nodes, a concept sometimes referred to as the economic majority. A UASF requires a lot of industry support and coordination, which is good practice for eventual hard forks which requires even more industry coordination. In the past, a UASF was successfully carried out to activate the P2SH soft fork (BIP16). The UASF concept was combined with SegWit activation in the BIP148 proposal which can be found here: github.com/bitcoin/bips/blob/master/bip-0148.mediawiki.

What is a MASF?
MASF stands for Miner Activated Soft Fork. It’s a mechanism by which miners trigger activation of soft forks when a majority signals the readiness to upgrade. This allows for a faster activation time for the soft fork, leaving full nodes to upgrade at their leisure. This method is a tradeoff, because it puts trust in the hash power actually enforcing the new rules. If they do not, it can cause various invalid chains on the network. For example, this was the case with BIP66, when hashpower indicated they had upgraded when in fact more than 50% had not. The other tradeoff is that the method allows a small number of hash power to veto activation of the soft fork for everyone on the network. Overall, if everyone cooperates, this method is very convenient and has been used to successfully activate multiple soft forks in the past such as BIP65 CLTV and BIP112 CSV.

What is BIP148?
BIP148 is a UASF that is designed to cause the existing SegWit MASF deployment to cause activation in all existing SegWit capable node software (which currently is 80% of the network nodes). How does BIP148 Work? From August 1st, 2017, miners are required to signal readiness for SegWit by creating blocks with the version bit 1. This will cause all SegWit ready nodes, which make up over 80% of the network, to activate and begin enforcement. Link for reference: luke.dashjr.org/programs/bitcoin/files/charts/segwit.html. Miners must also check blocks prior to their own and ensure that they also signal for SegWit, and only build on those blocks.

Why BIP148 and not a direct flag day UASF for Segwit?
To be clear, BIP148 is a soft fork that requires miners to activate the existing SegWit deployment. This is not the standard for UASF because normally nodes would just begin enforcement on a given “flag day”. However, almost 80% of the network has already upgraded to SegWit capable node software, in anticipation of miner triggered activation. A new “SegWit UASF” deployment would require all nodes to upgrade again which will take considerable time. For this reason, the shortened route to SegWit activation is to require blocks to signal for SegWit activation. In general, the block signalling mechanism is only supposed to be a coordination method that makes accelerated activation possible. In 2012, P2SH was activated by UASF with a simple flag day.
BIP148 was created to avoid having to force most users to upgrade their software. A vast majority of the nodes currently deployed are aware of the BIP9 signalling for SegWit. BIP148 is designed to motivate miners to signal for SegWit so that it is activated in a way that even users who are not running BIP148 will get the benefits of the activation of SegWit. For more information on the benefits of SegWit, please visit: segwit.org.


What do users need to do to enforce BIP148?
It is recommended that users do not update unless an economic majority commits to updating and users are aware of the risks and mitigations of a failed UASF deployment.
Users aware of the risks and who want to commit should use clients that enforce BIP148. Users that run full nodes would upgrade to one that enforces BIP148, or run their node behind an upgraded border node. Users of light clients (like mobile wallets) should check with each vendor to see their support for BIP148. We plan on documenting any public responses from wallets regarding BIP148 support. Satoshi Portal Electrum Server for UASF: 158.69.102.114 port 50002


What do miners need to do to enforce BIP148?
Prior to August 1st, 2017, miners should either:
  1. Update their node software to a BIP148-enforcing version; or

  2. Run a BIP148 border node to filter out invalid blocks, and update their existing mining software to produce blocks with version 1 bit enabled, to vote for Segwit activation
What are the various scenarios that could happen from BIP148?
BIP148 requires support from the economic majority, particularly exchanges and wallets. If this does not occur, node software supporting BIP148 should not be run after August 1st as it will cause a chain split leading to the abandonment of BIP148. There are strong economic incentives in the Bitcoin system for nodes to cooperate and remain in consensus to prevent chain splits. If the economic majority is signalling as of August 1st, miners have many incentives to follow along. Not following along would make it difficult to sell coins mined after August 1st as the blocks would not be accepted by the economic majority. Essentially, miners would be producing an altcoin not recognized by users and exchanges, making them less useful and in lower demand.

Some miners could opt to ignore the BIP148 rule and attempt to split the chain, but this would require a majority of miners who would be out of consensus from the rest of the economic majority.
If a majority of hash power follows BIP148, all nodes will follow the chain regardless of if they are running BIP148. Non-compliant blocks will be orphaned. All SegWit nodes will eventually activate SegWit.
If a minority of the hash power (under 51%) follows BIP148, nodes running BIP148 will be fine, but those not running BIP148 will be out of consensus with the rest of the economy. In this scenario, the more of the economy that runs BIP148, the better. Miners will find it difficult to sell their coins leading economically motivated miners to start enforcing BIP148.


Why was the date of August 1, 2017 chosen?
Because BIP9 is time based, BIP148 needs to account for the possibility for some of the hash power to exit (eg. to mine another fork) which would make block intervals longer. The August 1st date allows for the economic majority to successfully activate SegWit. Theoretically, if the hashpower drops by up to 85%, it might take up to 13 weeks to complete an activation period. In this scenario, SegWit will still activate for all BIP148 compliant nodes.


How can we show support for BIP148?
The best way to show support is to champion it through social media (Twitter, Facebook, etc…) and petition businesses and wallets to support it. Many users have already installed (or upgraded to) Bitcoin Core UASF BIP148 and this is best option for those who use own nodes to send and receive bitcoin.
Users who cannot upgrade existing Bitcoin Core can change their node’s user agent string to include BIP148, but such nodes will have to be upgraded to UASF BIP148 in order to be able to function on the BIP148 chain after August 1.

To signal #BIP148 on Linux on your node without a software change:
[code]echo "uacomment=UASF-SegWit-BIP148" >> ~/.bitcoin/bitcoin.conf && bitcoin-cli stop && sleep 5 && bitcoind[/code]

To signal #BIP148 on Windows, you can edit the shortcut for Bitcoin as follows:
[Image: windows148.png]
N.B. This will not enforce UASF on your node; it will only signal that you support it at this stage. If you intend to use BIP148 to send and receive bitcoin after BIP148 activation, make sure to install Bitcoin Core UASF BIP148 prior to August 1, 2017.


How can I compile BIP148 myself or download signed binaries?
Signed binaries can be downloaded here. To build from source, follow the instructions below.

First, install all necessary dependencies which are mentioned in the official Bitcoin build instructions:
OS
LinkOpenBSD
https://github.com/bitcoin/bitcoin/blob/...openbsx.md
OSX
https://github.com/bitcoin/bitcoin/blob/...ild-osx.md
Unix
https://github.com/bitcoin/bitcoin/blob/...ld-unix.md
Windows
https://github.com/bitcoin/bitcoin/blob/...windows.md


You can also use the gitian build system, which is a bit more complex, but generates deterministic builds which can then be verified by the signatures of some core developers:
Source
LinkGitian
https://github.com/bitcoin/bitcoin/blob/...uilding.md
Signatures
https://github.com/UASF/gitian.sigs

The next step is to clone the UASF repository:
[code]git clone https://github.com/UASF/bitcoin.git bitcoin_bip148
cd bitcoin_bip148
git checkout 0.14-BIP148
[/code]

and then continue with the default compiling steps which are mentioned in the official build instructions:
[code]./autogen.sh
./configure
make
make install # optional
[/code]

Finished - you can run now your UASF BIP148 node.
Are there any groups which I can join?[/url]
Yes. There are two slack channels on 
slack.bitcoincore.org:
  • #UASF for general talk

  • #UASF-SUPPORT for people who want to setup their BIP148 node

Feel free to join, we are always happy about people which are interested and would like to discuss with us!


Can BIP148 be cancelled?
Yes. In the event that the economic majority does not support BIP148, users should remove software that enforces BIP148. A flag day activation for SegWit would be the next logical steps and require coordination of the community, most likely towards the end of 2018.

Does node count determine activation?
No. Users that decide to enforce the new rules will only follow blocks that conform to the existing rules which will in turn cause miners to activate SegWit. A UASF could be enforced by any number of economic nodes, although hash power may only choose to follow such rules if there was significant economic weight behind it.

Will a UASF cause a chain split?
Soft forks rely on the economic incentives of the majority of miners and economic actors to reject invalid blocks based on the new ruleset. Since the new BIP148 rules are a stricter set than the old rules, any chain split means the chain with the old rules would be in danger of being wiped out. If the majority of miners enforce the new ruleset, all blocks produced that are invalid in the new ruleset will become orphaned. This economic incentive pushes miners to enforce the new rules. A UASF uses similar economic incentives. If the majority of hashing power enforces the new rules, chain splits remain temporary as with a solely miner enforced soft fork.

If the majority of hashpower does not enforce the rules, a chain split would occur. If there is a greater demand for the blocks produced by the BIP148 miners, then profit-driven miners would eventually flock to this chain, leading to the orphaning of the pre-soft-fork chain. If the demand is less for the soft-fork chain, then both chains may co-exist indefinitely.

Is BIP148 a hard fork?
No, BIP148 isn’t a hard fork. A hard fork is often confused with a chain split. A hard fork is a type of chain split where the rules are loosened to allow previously disallowed blocks or transactions. A soft fork is a tightening of the rules. A soft fork will result in a converged chain if the majority of hashpower enforces its rules. For a more detailed explanation of types of forks and chain splits, see Chain Splits and Resolutions.

I thought miners vote on proposals?
Miner activated soft forks are a convenient shortcut to activating soft forks because it allows the changes to activate before a significant portion of the economy upgrades. The signalling process is just to coordinate when a supermajority of hashrate has upgraded, nodes can then activate and begin enforcing the new rules. It was never intended to be a vote although it has an unintentional veto where a small amount of hash power can hold up the process.

Ultimately consensus is decided by the economic nodes in the ecosystem since they validate the chain and engage in economic activity. Ultimately even miner activated soft forks (MASF) are enforced by the nodes. The miners simply trigger activation in the nodes.
A UASF forgoes the need for miner signalling because economic nodes are given more time to upgrade to the new rules and begin enforcing in the future. A UASF in no way impedes the operation of non-upgraded miners, nor disenfranchises them in any way. Miners always have the freedom to produce blocks following any rules they wish, but if they fall out of consensus with the economic nodes, their blocks will be rejected by the network.

Can miners attack the chain in the event of a split?
Miners can always attack any chain at any time, but must do so by exerting real opportunity costs - they have to stop mining for profit. There are two main types of attacks. The first attack would be mining empty blocks. In the case of a chain split, this kind of attack would actually be beneficial - it would allow the chain to reach a difficulty retarget period faster. The second kind of attack is an active 51% attack on the chain. This type of attack requires a majority of hash power colluding to orphan valid blocks that have been mined. This kind of attack is always possible in Bitcoin, but can be defeated by changing the Proof of Work. These types of attacks are discouraged due to economic incentives- there typically is more to gain by cooperating than attacking.

Won’t blocks become very slow if there is a split?
Both sides of a chain split will produce slower than normal blocks until the difficulty period resets. This time will be dependent on the allocation of hash power. For example, if 25% of the hash power was left on a chain, it would take four times as long (8 weeks) to reach a retarget period. After this period, blocks would return to 10 minutes. Congestion would also likely result in higher fees, which would encourage more mining on this chain and faster blocks until equilibrium would be reached.

How can I make sure I am protected in the event of a chain split?
This will depend on what type of wallet you use. In the case of a wallet using a centralized service’s nodes, make sure the nodes their service uses are upgraded. In the case of something like Electrum, make sure the Electrum server you are using is upgraded. Ultimately, any non-fully validating wallet will derive information about balances from a fully validating node. You must take whatever steps you have to in order to ensure your wallet is connected to an upgraded BIP148 nodes.

Where do I download software that enforces BIP148?
Successful User Activated Soft Forks require a strong consensus from the economy to be successful. BIP148 also is subject to changes as it is reviewed, so some minor details may change before it is ready. Please check regulary to be up to date with the latest version.

What is BIP8?
BIP8 is a modification to BIP9. BIP9 was the deployment mechanism for soft forks in the past that relied on miners signalling 95% readiness for activation. It was successfully used to activate BIP65 (OP_CHECKLOCKTIMEVERIFY) and BIP68/BIP112/BIP113 (CHECKSEQUENCEVERIFY/Median Time). BIP9 allows for upgrades to the system whenever a supermajority of miners are ready to enforce the changes, allowing for faster upgrades than a UASF may allow. Every 2016 blocks, if 95% of those blocks signalled readiness for the proposed change, the soft fork enforcement would become mandatory in 2016 blocks. Each change is given a fixed timeframe to achieve this activation, such that any change that is not activated may have its bit reused. Proposals that do not achieve activation expire at the end of their time period, but may be renewed if there is sufficient interest.
BIP8 modifies BIP9 to automatically convert into a UASF at the end of its activation time. This avoids the problem of a miner veto while still allowing miners to begin enforcing the rules sooner than a pure UASF would allow. Once the final period completes after the timeout period, the rules become mandatory, regardless of signalling.

Can BIP8 be applied to SegWit?
There was a proposal made by Shaolinfry to use BIP8 to deploy SegWit. The proposal would set a new version bit for deployment after the current proposal would expire, and would lock-in in April 2018. Miners would still be able to activate SegWit prior to the this date, but failure to activate would result in a mandatory lock-in.

Unlike BIP148, this proposal would not require miners to signal version bits for SegWit or create SegWit blocks. The only requirement for miners is to not build on top of blocks that are invalid under the SegWit rules.

A Bangalore restaurant’s unsuccessful Bitcoin pilot has cemented views that in India, Bitcoin is not the sensation in real life that it is online.

Local news resource Factor Daily reports that a local restaurant, long recognized for its Misal Pav and Mutton Thali, has yet to attract a single paying customer during its year-long Bitcoin payment trial.

“Not a single person has paid in Bitcoins until now,” owner Suryawanshi told the publication. “We wanted people to know what Bitcoin is. Those days it was just taking off but it’s now mellowed down a bit.”

The story could not be more different to the exploding online Indian Bitcoin market, with exchanges reporting consistent growth and LocalBitcoins setting new records.

Following India’s disastrous currency reforms last November, the pace quickened, with users looking to shore up their savings as cash supplies were squeezed for months on end.

As a practical tool on the ground, however, the situation in the country is reminiscent of that in Japan.

Despite a giant drive to increase Bitcoin’s profile among mainstream consumers, reports have stated that using the virtual currency in brick-and-mortar establishments is still cumbersome.

“Places like these don’t really need bitcoins,” a self-outed Bitcoin millionaire added to Factor Daily, adding that in spite of everything, cash wallets were “enough” for most.

When there is a rapid growth in any of the crypto-currencies and assets such as Bitcoin, Ether, Zcash and others, many will call it out as a bubble. Indeed, on a relatively short time scale it clearly looks like a bubble.

The entire crypto-currency market capitalisation currently stands at around US$100 billion; it was US$60 billion one month ago. But Bitcoin was worth 1/100 of a US cent in June of 2009, 7 cents in June 2010, and US$7 in June of 2012.

Recently all eyes were on Ether. Over a 90 day period, Ether appreciated twice as quickly as Bitcoin did in late 2013, when Bitcoin crashed to around 35% of it’s highest value. Aside from the 2013 crash, Bitcoin has experienced smaller crashes many times since, but is now worth double its 2013 high.

In the longer term, these are fluctuations around a strong growth trend. Crashes will cause some to abandon the field. But signals of longer term growth in these crypto-currencies and assets point to a possible emergence of a new type of market, through the building of a new economic infrastructure.

Ether is the token of the Ethereum blockchain, a platform that runs “smart contracts” through a distributed online ledger that records transactions. It’s second only to the crypto-currency Bitcoin in price. Some believe it will one day overtake Bitcoin (a process dubbed “The Flippening”).

Price hikes not the sign of a bubble
Fundamental aspects of the technology that underpins crypto-currencies and assets are causing people to re-imagine, and then enact, new ways of creating and exchanging value online.

The key difference between Bitcoin and Ethereum is that you can use Bitcoin for payments, but you can use Ether to automate any number of processes using smart contracts.

While many use cases for Ethereum are still at the proof-of-concept stage, it is now attracting the attention of major banks, businesses and governments, all interested in the potential of the technology to provide greater efficiency and transparency in transactions. That normalisation has collapsed the implicit risk premium attached to this technology.

Venture capitalist Albert Wenger describes the current activity in crypto-currencies and assets as “fat protocol investing”. To explain what this is, take the example of the underlying internet and web protocols (TCPI/IP and HTTP), used to build and run websites. These are not able to store value - therefore they are “thin protocols” in Wenger’s terminology. So instead, people invest in companies that make software (applications) and hardware that rely on these protocols.

 and storing data generated by users through their online interactions. Meanwhile, users, and the developers who created internet and web protocol, received nothing in return. Blockchain is a “fat protocol” because it can be monetised, including incentives for developers but also for users. For example, the creator of JavaScript and co-founder of Mozilla Brendan Eich, recently released an Ethereum-based web browser through which users can be paid for the attention they give to advertisements.

What is making crypto-assets and currencies appear bubbly is the way in which many of these new platforms and applications have raised money through what are called initial coin offerings. An initial coin offering (a word play on ‘initial public offering’) is a mechanism by which developers sell the tokens associated with their platform to the public. Depending on the structure of the offering, buyers can usually then trade the tokens, creating secondary markets. As the founder of Ethereum, Vitalik Buterin, has noted, no-one has figured out the right model for these offerings.

This could be due to the immaturity of the Ethereum platform and ecosystem (which started development in 2013 and went live only in 2015). What we’re observing here is a new economic infrastructure being built and coming online. In tweets on Tuesday, Buterin distanced himself from initial coin offerings, stating he would no longer agree to be an advisor.

So while the current speculation in crypto-assets should make us pause, this is not speculative like tulips, or gold mining stocks. It is speculative like building a new city, in that infrastructure needs to be developed first before you get to see who moves there.

A further point to note is that investment bubbles are actually useful and important mechanisms for building new technologies because of the way they concentrate speculative resources on a new technology to facilitate exploration.

There is an enormous effort proceeding to building new crypto businesses and infrastructure on the Ethereum platform. If this platform does indeed begin to carry large parts of the global economy as predicted by Deloitte, a business consultancy, then it’s still massively undervalued.

The fragmented mandate on Bitcoin’s scaling issue has been going on for more than a year. The issue revolves around the size of the blocks which are added to its blockchain. Bitcoin blocks have a limited ‘storage’ capacity of 1MB under the current popular system of Bitcoin Core. With increasing usage, congestion issues have been reported on the Bitcoin network, resulting in more time and transaction fees necessary for verifying transactions. To resolve this, different sections within the Bitcoin community pitched different solutions to enable smoother running by decongesting the blocks. However, there was a failure to reach a consensus.
Blocks are files where data pertaining to the Bitcoin network is permanently recorded. A block records the most recent Bitcoin transactions that have not yet entered any prior blocks. Thus, a block is like a page of a ledger or record book. Each time a block is ‘completed’, it gives way to the next block in the blockchain. A block is thus a permanent store of records which, once written, cannot be altered or removed.
"Such debates are not a one-time issue"
Mahin Gupta, co-founder and CTO of Zebpay told Investopedia, “Bitcoin is a decentralized technology. Which means discussions on changes to the network happen in the open, in public and not behind closed conference room doors. These debates are visible and can be messy. This is a feature of bitcoin, not a problem. Such debates are not a one-time issue. They will keep happening as bitcoin grows in popularity. I am confident that the community will come to a consensus soon and then we shall debate how to scale it again.” (Related reading, see: What Is Bitcoin Unlimited?)

Among the various solutions, Bitcoin Unlimited, SegWit2x, BIP148, gained more than attention than the others.



Segwit2x

SegWit2x came into the limelight in May when the Digital Currency Group (DCG) published a post titled, “Bitcoin Scaling Agreement At Consensus 2017.” According to that post, the community supports the parallel upgrades to the Bitcoin protocol based on the original Segwit2Mb proposal. It includes: a) Activate Segregated Witness at an 80% threshold, signaling at bit 4, b) Activate a 2 MB hard fork within six months.

According to the post, the group of signed companies is a good representation of the Bitcoin ecosystem. As of May 23, this group represented: 56 companies located in 21 countries, 83.28% of hashing power, $5.1 billion monthly on chain transaction volume and 20.5 million bitcoin wallets. Under the original proposal, 95% threshold was needed which has been lowered to 80%. The schedule for SegWit2x mentions July 21 as the day when signaling begins.


BIP148

Meanwhile, BIP148, another scaling solution, will be triggered on August 1, 2017. BIP148 is all set for User Activated Soft Fork (UASF) – “a mechanism where the activation time of a soft fork occurs on a specified date enforced by full nodes, a concept sometimes referred to as the economic majority.” Normally, a USAF does not to seek miners support, as it's a ‘user-activated’ soft fork. However, in this case, it does.

The UASF post reads, “BIP148 is a UASF that is designed to cause the existing SegWit MASF (miner activated soft fork) deployment to cause activation in all existing SegWit capable node software (which currently is 80% of the network nodes). From August 1st, 2017, miners are required to signal readiness for SegWit by creating blocks with the version bit 1. This will cause all SegWit ready nodes, which make up over 80% of the network, to activate and begin enforcement.”

With Segwit2x and BIP148 going active one after the other, fear on incompatibility has emerged. To this, John Light has recently said in his blog post, “As far as I can tell, BIP148 is not incompatible with the Segwit2x agreement. At the very least, BIP148 does not violate the spirit of the agreement, since it both activates SegWit and in no way, prevents signatories from running code for a 2MB hard fork once it’s ready.”

Bitcoin Unlimited

The third solution, Bitcoin Unlimited, advocates complete freedom and flexibility to increase the size of blockchain and this will be done by miners. Jihan Wu has been advocating and pushing for accelerated adoption of Bitcoin Unlimited. BITMAIN, a company co-founded by Wu has recently published a blog which calls, “BIP148 is very dangerous for exchanges and other business.” (Related reading, see: Who Is Jihan Wu, , and Does He Basically Control Bitcoin Today?)

A split in the network is the last thing the Bitcoin community would want at this point. So, are these developments a warning sign? May be not. “We recently partnered with China in a big way, if any of our business models were threatened by the scaling debate with bitcoin blockchain, I would be the first to give my opinion. Right now, I have no comment” said Ronny Boesing, CEO of OpenLedger to Investopedia.

A new gold rush is picking up speed as bitcoin doubles the size of its fund under the BIT-XBTE’s management. The fund that was around $50 million on May 1st has jumped to $100 million a few days ago, which is an impressive growth.

The head of trading and operations at XBT Provider, Jean-Marie Mognetti, has stated that during the last two months, the Provider’s exchange of the traded Bitcoin notes has seen a major demand increase from industrial as well as retail investors. Everyone is searching for exposure to bitcoin, which is a sure sign that its rise isn’t going to stop anytime soon.

Bitcoin’s increase has gone up by 200% since the beginning of the year, but even that isn’t as fast as the growth of other currencies. For example, Ethereum has gone up over 3,000% this year alone.

The Bitcoin Tracker Euro ETNs, as well as Bitcoin Tracker One, are currently available in both Euros, as well as in Swedish Krona.

This all happened very soon after Goldman Sachs, the US investment bank, decided to announce the need for analyst coverage concerning the cryptocurrencies. They stated that the client demands were simply too much. Despite the fact that the price of Bitcoin wasn’t exactly specified, Goldman Sachs sees the buying opportunities somewhere in between $1,915 and $2,330.

However, Sheba Jafari, the chief technician has issued a warning for the clients, in which he advised against trading. The reason for this is that earlier this week, Bitcoin breached the $3,000. Instead, he advised waiting for it to go between $1,915 and $2,330.

Also, a few days ago, on June 13th, another report called “Blockchain: Unchained” was issued by Morgan Stanley. In the report, the commitment to exploring the technology on which Bitcoin and similar cryptocurrencies are built on was underlined. Caution is also advised due to the lack of any regulations in their price. Currently, that price is around $2,600.

According to Goldman Sachs, this attraction to the virtual currencies and Bitcoin in particular is due to the lack of volatility when it comes to other asset classes. The often changes in the currencies’ worth can also offer many opportunities for some.

Another big news related to this, is the new team up between XBT Provider and Xapo, a leading cryptocurrency custodian. Xapo is a very secure Bitcoin holder, and besides the wallet services, it also provides a vault insurance.

When it comes to protecting your Bitcoin, the safest way would be to hold them in the cold storage. What that means is that you would write the amount that you hold on a paper and store it on many different physical sites, or in wallets that don’t have a connection to the internet.

XBT Provider’s head of investor relations, Ryan Radloff, has stated that adding Xapo to XBT Provider was a very critical step. Now that it’s done, the company’s products will be sure to remain the most professional bitcoin investment product on a global scale.

In Indiranagar, a posh neighbourhood in Bengaluru dotted with upscale pubs and theme restaurants, is an eatery that serves Maharashtrian cuisine. It is not big and if you don’t look closely, you might miss Suryawanshi Restaurant.

The Misal Pav and Mutton Thaali at Suryawanshi get due credit from food lovers. But what most Bengalurians, fintech gurus and startup junkies, including FactorDaily, seem to have missed is the fact that it happens to be the first restaurant in the city — and, likely, in all of India — that accepts Bitcoins in payment.

“We started accepting Bitcoins almost a year ago,” Kailash Suryawanshi, the owner of Suryawanshi restaurant told FactorDaily. It accepts payment through Bitcoin wallets like Coinsecure, Unocoin or Zebpay

The restaurant came to our notice when Pravin Jadhav, chief product and growth officer, Servify, recently posted the picture of a “Bitcoins accepted here” sticker at the restaurant on Twitter.

“I’m not a tech savvy person at all. I’m the opposite,” said Suryawanshi. But then, how did Bitcoins happen? “A friend of mine introduced me to it. I bought a lot of Bitcoins last year when it was priced around Rs 35,000,” said Suryawanshi, a Marathi businessman who now runs two of these eateries in the city.

When his quest to find authentic Marathi food failed, he decided to start a restaurant of his own in 2013. Besides the Indiranagar outlet, Suryawanshi operates another one in Whitefield with a full kitchen. The Indiranagar restaurant was opened because he realised there was a scarcity of good Marathi cuisine in the area.

“Not a single person has paid in Bitcoins until now” — Suryawanshi  

For all the geek cred that Bengaluru boasts of, Suryawanshi’s little experiment hasn’t found many takers yet. “Not a single person has paid in Bitcoins until now,” said Suryawanshi, who has been in Bengaluru since 2004. “We wanted people to know what Bitcoin is. Those days it was just taking off but it’s now mellowed down a bit.”

A handful of businesses in India have started accepting Bitcoins as payment, including books seller Sapna and Dharwad International School, Unocoin says on its website.

With Bitcoin’s recent spike in valuation, Suryawanshi’s investment has grown multifold. Between June 2016 to June 2017, the price of a Bitcoin has gone from about $700 to $2500.

Bitcoin’s might be killing it in the virtual world. But it still has a long way to go in the real world. “Places like these don’t really need bitcoins. PayTM and cash wallets are enough,” says Akshay Haldipur, one of India’s Bitcoin crorepatis (read Inside the fabulous life of Bitcoin crorepati Akshay Haldipur).

In most small businesses, despite the government’s push towards digital currencies, cash remains the easiest way to transact. It’s also tougher for Bitcoins to become mainstream because sometimes it takes longer to authenticate.

“I think globally, people are looking at it more as an asset rather than money,” says Benson Samuel, chief technology officer of Coinsecure, an India based Bitcoin exchange. “Even in the event of money, retail payments are a bit clumsy in terms of confirmations.”

Suryawanshi, who is a typical mainstream user of Bitcoin, also feels that there will be more takers for the crypto currency when the regulatory cloud over Bitcoin lifts. India’s central bank, the Reserve Bank of India, has cautioned people from trading in virtual currencies.

Japan recognised Bitcoin as a legal payment method in February. In April, the Indian government said it will set up an inter-disciplinary committee to take a close look at the circulation of crypto currencies in the country. There’s a fair bit of support to legalise Bitcoins in India. Consumer protection and money laundering will be key issues the committee will look to tackle.

A new initiative designed to help Bitcoin users with the upcoming fork advises them to maintain 100 percent control of their Bitcoin, rather than keeping it in exchanges.

The reality is clear - most Bitcoin blocks hit the block size limit of 1 MB and are plagued by fees and slowdowns. The solution, though, is still up in the air as debate rages about how change should happen.

One solution, the user-activated soft fork (UASF) is scheduled to go live on August 1, while another competing group has threatened to split the chain if that occurs.

1August.org claims to be a neutral third party designed to help users understand and navigate the upcoming fork, and how to best protect their Bitcoin. Because a fork would create duplication, the best solution for users is to be able to transact on both chains, should a fork occur.

At this time, they are advising that users maintain 100 percent control of their Bitcoin, rather than keeping it in exchanges such as Coinbase or Bittrex. The only way to completely control Bitcoin is to be in control of your private keys on either a wallet application or a paper wallet.

As they continue to evaluate the situation, 1August has promised to continue informing users in an unbiased fashion.

Hi Guys, I would like to share this news.

Jed Mccaleb, June 12, 2017:

Everyone is talking about tokens these days. At this past Consensus conference I was at a dinner and someone from poloniex was there. People were asking him how they decided what new coins to list and how they were going to keep up with the accelerating number of new tokens and coins that are being created. The answer was basically that they can’t. No one can. It will become an increasing challenge for exchanges to not only list all the tokens and coins people are asking for but to also create the multitude of pairs between all of them.

This is another reason we hope people start moving to a more decentralized exchange model. Instead poloniex could be a Stellar anchor for the tokens and coins it does support and these could then be traded freely with the tokens other anchors choose to support. But even better would be to avoid all that and just create your token directly on Stellar skipping the need for an anchor altogether.

There is clearly a lot of hype around these things now and although many will surely fall by the wayside a lot of them make sense and are moving things forward. What is great is that Stellar is built to keep track of any arbitrary token. It makes it very easy to issue a new token out into the world. There are a lot of benefits to using Stellar for this:

    Quick settlement. 3-5 seconds for a token holder to send the token to someone else.
    Cheap transactions
    Built in exchange with any other token, asset or currency in the network.
    Optionally control of who can hold your token.
    Ability to do voting, dividends or awards all in the same network.
    Unify how exchanges and others can deal with your token. If an exchange supports Stellar than it can easily list all other tokens issued on Stellar.

Let’s issue a token

It is trivial to create assets on Stellar. It was built to keep track of any arbitrary asset, or currency so can also be easily used for all these new tokens that are popping up.

Here I’ll walk you through how you do this technically by creating an example token…

Let’s say I want to make a HUG token. Anyone can send me one of these HUG tokens and I’ll hug them. I want to create 5000 of these and want to ensure the world that no more are ever created so no one has to be concerned with hug inflation.
There are wallets that provide an easier interface for many of these steps but I’ll just use the Stellar laboratory.
