Restribute ~ Wealth re-distirbution by blockchain hardfork ~ Tomoaki Sato
After the DAO hardfork Ethereum has 2 networks, Ethereum and Ethereum classic.
By seeing the fact, Gini index can be decreased by blockchain hardfork.
Re-distribution can be good even for people who have wealth in some blockchain protocol, because it increases engagement, and bring more network value to the blockchain.
This is not only company /project level, also can be used for governmental level to do democratic re-distribution of wealth not by centralized authority.

What price will pi network be listed on exchangesDOT TECH
The rate at which pi will be listed is practically unknown. But due to speculations surrounding it the predicted rate is tends to be from 30$ — 50$.
So if you are interested in selling your pi network coins at a high rate tho. Or you can't wait till the mainnet launch in 2026. You can easily trade your pi coins with a merchant.
A merchant is someone who buys pi coins from miners and resell them to Investors looking forward to hold massive quantities till mainnet launch.
I will leave the telegram contact of my personal pi vendor to trade with.

US Economic Outlook - Being Decided - M Capital Group August 2021.pdfpchutichetpong
The U.S. economy is continuing its impressive recovery from the COVID-19 pandemic and not slowing down despite re-occurring bumps. The U.S. savings rate reached its highest ever recorded level at 34% in April 2020 and Americans seem ready to spend. The sectors that had been hurt the most by the pandemic specifically reduced consumer spending, like retail, leisure, hospitality, and travel, are now experiencing massive growth in revenue and job openings.
Could this growth lead to a “Roaring Twenties”? As quickly as the U.S. economy contracted, experiencing a 9.1% drop in economic output relative to the business cycle in Q2 2020, the largest in recorded history, it has rebounded beyond expectations. This surprising growth seems to be fueled by the U.S. government’s aggressive fiscal and monetary policies, and an increase in consumer spending as mobility restrictions are lifted. Unemployment rates between June 2020 and June 2021 decreased by 5.2%, while the demand for labor is increasing, coupled with increasing wages to incentivize Americans to rejoin the labor force. Schools and businesses are expected to fully reopen soon. In parallel, vaccination rates across the country and the world continue to rise, with full vaccination rates of 50% and 14.8% respectively.
However, it is not completely smooth sailing from here. According to M Capital Group, the main risks that threaten the continued growth of the U.S. economy are inflation, unsettled trade relations, and another wave of Covid-19 mutations that could shut down the world again. Have we learned from the past year of COVID-19 and adapted our economy accordingly?
“In order for the U.S. economy to continue growing, whether there is another wave or not, the U.S. needs to focus on diversifying supply chains, supporting business investment, and maintaining consumer spending,” says Grace Feeley, a research analyst at M Capital Group.
While the economic indicators are positive, the risks are coming closer to manifesting and threatening such growth. The new variants spreading throughout the world, Delta, Lambda, and Gamma, are vaccine-resistant and muddy the predictions made about the economy and health of the country. These variants bring back the feeling of uncertainty that has wreaked havoc not only on the stock market but the mindset of people around the world. MCG provides unique insight on how to mitigate these risks to possibly ensure a bright economic future.

The European Unemployment Puzzle: implications from population agingGRAPE
We study the link between the evolving age structure of the working population and unemployment. We build a large new Keynesian OLG model with a realistic age structure, labor market frictions, sticky prices, and aggregate shocks. Once calibrated to the European economy, we quantify the extent to which demographic changes over the last three decades have contributed to the decline of the unemployment rate. Our findings yield important implications for the future evolution of unemployment given the anticipated further aging of the working population in Europe. We also quantify the implications for optimal monetary policy: lowering inflation volatility becomes less costly in terms of GDP and unemployment volatility, which hints that optimal monetary policy may be more hawkish in an aging society. Finally, our results also propose a partial reversal of the European-US unemployment puzzle due to the fact that the share of young workers is expected to remain robust in the US.

4. What’s DApp ?
• Decentralized Application, no centralized server, user can run
the app locally.
• Instead of the server, having backend of blockchain with the
consensus algorithm.
• DApps issue their own tokens, users and developers are stake
holders
About DApps
No copyrights, All rights decentralized.
DApp
5. More detail definition?
About DApps
FromDavid Johnston’s The General Theory of Decentralized Applications, DApps
https://github.com/DavidJohnstonCEO/DecentralizedApplications/blob/master/README.md
1. The application must be completely open-source, it must operate autonomously, and with no
entity controlling the majority of its tokens. The application may adapt its protocol in response
to proposed improvements and market feedback but all changes must be decided by consensus
of its users.
1. The application's data and records of operation must be cryptographically stored in a public,
decentralized blockchain in order to avoid any central points of failure.
2. The application must use a cryptographic token (bitcoin or a token native to its system) which is
necessary for access to the application and any contribution of value from (miners / farmers)
should be rewarded in the application’s tokens.
3. The application must generate tokens according to a standard crytptographic algorithm acting as
a proof of the value nodes are contributing to the application (Bitcoin uses the Proof of Work
Algorithm).
There are many definition for “DApp”, but this David Jonhston’s at DApps Fund
definition is clear and maybe the first one.
No copyrights, All rights decentralized.
6. Must be open source ?
Some projects are not completely open source, some of the codes are open source.
Here’s the open source DApps references:

7. How to use DApps ?
About DApps
If you have used Bitcoin, you have already used or using DApp, but More “app” like
feeling things you can use and imagine by the following way.
1. Using github way - Google“github + {DApp name}”
2. Using official release way – Google “{DApp name}” and visit the site and install
3. Future way – DApp Browsing & installing “{DApp Name}”
3 Should be pointed out. In ethereum case, user can use Mist browser and search the DApps
from the place, and install, run on it.
No copyrights, All rights decentralized.
8. Why should we use DApps ?
About DApps
1. Decentralization– No censorships from centralized server
2. Privacy – Related to decentralization, generallly, your data is shared with encrypted format.
3. Secure transactions – P2P communication secured by blockchain
4. Useful financial Transactions – Ex) Bitcoin
5. Not just consuming, you can be involved in DApp network as a stake holder, developer, miner, etc roles.
And more metirs we will find in the relationships between DApps, and smart contracts. Some DApps like Gold
Feeds DApp helps other DApps to develop trust-less application.

9. Why media needed ?
About DApps
You can be involved in the DApp, easily by having tokens, or currencies.You are not just to be user,
can be developer, miner, smart contractor, as many roles.
However DApp itself is currently not penetrated to users. One of the reason is userability for

10. I heard a lot about “Smart contracts”
what is the meaning of that ?
11. Smart contracts ?
From the 1997, Nick Szabo cryptographer suggest the basic idea of smart
contract., and also here .
However after Smart contracts comes to life, there are also have many
definitions. Peter Todd, Bitcoin core developer says “no one has a clue
what a smart contract actually is, and if we did it’d need oracles”

12. The relationships between
DApps and Smart contracts ?
Currently there are some platforms for ‘Smart contracts’, such as Mastercoin, Nxt, Nem,
Counterparty.To describe the dapps, and smart contracts, let’s take two famous DApps,
Bitcoin and Ethereum.
When we talk about Ethreum and Bitcoin, some people misunderstand that.
Actually both of them are DApps, and can be able to run smart contracts.
About smart contract
No copyrights, All rights decentralized.
Not good Wide recognition
13. What kind of things are the place ?
This is the traditional legal paper alternative use case of the smart contracts.
For example, imagine the traditional paper contracts, when you enforce the contracts, you will go to
court, Just like that, you can write smart contracts as a legal contract for the assurance of agreement,
and publish to blockchain. And when you enforce it, you will send message. However there are ofcource
many things to notice here’s the great link of the lawyer, who is also engineer, and the founder of Eris,
smart contracts platform.

14. Bitcoin and Ethereum can run
smart contracts ?
Yes, both of Ethereum and Bitcoin, and the platforms described are running smart contracts, but the main differences
are
・Turing Completeness
・Value Blindness
・Lack of state
・Blockchain-blindness
