大多數人是姣婆
是的，收到很多公司privacy政策更新的邮件，应该是上次facebook事件的后续。。。！
對﹐blockchain技術是時候思考privacy的重要性
我觉得现在的情况跟几年前的情况已经不同了，现在并不是说你看中了一个币，然后梭哈进去长持一段时间之后就可能挣到钱，现在已经被越来越多的人普遍接受和发现之后，这个东西估计就很难再长久下去了。
所以建议大家见好就收吧。

還早得很呢﹐blockchain技術連privacy同scalability都未解決﹐等到這兩方面解決後才會真正穩定下來
能解決這兩點的幣會大爆發
In the series Billions they talk about getting paid in cryptocurrency in several episodes. A hedge-fund manager got banned from trading by the government so he'll name another guy as the head of trading, direct the trades and get paid in cryptocurrency so the government can't see that.
Axe!
There will be more and mor people with btc buying experience. Having that experience, people will put more money in if the price is low enough. This is human nature. There will always be support. We are just finding
Electroneum﹐一隻以mass adoption 廣泛採用為目標的貨幣﹐已經推出了android app﹐各位可以用電話挖礦了﹐該程式只是模擬挖礦的過程﹐計算手機的運算速度以發放相應的ETN﹐並不是真的以電話運算解數學方程﹐因此不會造成電池損耗﹑電話過熱的情況。
每挖了5個ETN系統便會自動把它轉賬到錢包﹐有時並不會在有5個ETN的時候立刻轉﹐可能在7-10個的時候轉﹐但最終都一定會轉入錢包。
Electroneum 現排名47﹐每一個現價$USD0.046﹐可在cryptopia﹑kucoin﹑tradeorge等交易所買賣﹐據說月底會上hitbtc。
用電話挖礦比一般空投更可靠﹑更簡單﹑更高利潤! 可在google play 下載Electroneum by Electroneum Ltd.

How can an offline software create valid private key/public key pairs without communicating with the blockchain? The software must on its own know a certain private key would match a certain public key. Doesnt it mean there is a calculable relationship between private key and public key?
How can an offline software create valid private key/public key pairs without communicating with the blockchain? The software must on its own know a certain private key would match a certain public key. Doesnt it mean there is a calculable relationship between private key and public key?
private key is simply a 256 bit number is a huge range that is selected randomly. it is from 0x1 to 0xFFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFE BAAE DCE6 AF48 A03B BFD2 5E8C D036 4140.
when you generate a new address in your wallet (online or offline) what happens is that your wallet software randomly chooses a number in this range and that is your private key then uses some math to get the public key and then your address from that number. and this "math" is a one way street. meaning you get the public key from private key but you can not do the opposite. same with address. and that is the relationship.
example:
1. private key (number)
Code:
11253563012059685825953619222107823549092147699031672238385790369351542642469
your wallet, for convenience shows this to you in a special format called Base58Code:
5J1F7GHadZG3sCCKHCwg8Jvys9xUbFsjLnGec4H125Ny1V9nR6V
2. public key which is a coordinate on the Elliptic curve (y^2 = x^3 + ax + b)
Code:
0450863AD64A87AE8A2FE83C1AF1A8403CB53F53E486D8511DAD8A04887E5B23522CD470243453A299FA9E77237716103ABC11A1DF38855ED6F2EE187E9C582BA6
3. address which is SHA256 + RIPMED160
Code:
010966776006953D5567439E5E39F86A0D273BEE
again for convenience the same Base58 encoding is used here too:Code:

Wow so it's one way street. I think it's safe. Thanks! Though I am not sure how its converted.
If i can generate a wallet and corresponding private key offline, and those can fit in the blockchain when I go online
Well, they don't 'fit in the blockchain'. But they are valid, of course.
does it mean that there is a certain formula between a wallet and the private key?
A 'wallet' is a piece of software which manages your public-/private keypairs.
Most wallets use a 24 word seed to derive those keypairs (together with a counter for an (almost) infinite amount).
Can people use that formula to get my private key simply knowing my wallet address?
From knowing one of your wallets addresses (public keys; technically addresses don't exist, they are used for 'represantation') noone can calculate/crack/hack/etc.. your private key.
Thats the sense of a trustless secured system.
So the software knows a certain combination of 24 words matches a certain keypair. Obviously the software doesnt have all the possible combinations stored. It generates the 24 words and keypair using certain algorithm. Why cant this process be reversed?
It is every safe it will work same way all oline wallets works,and you can not have access to the wallet because your with the address you ca only view the wallet
Thank you but this is basic and is what the wallets claim. I knew the piece of information already. When i am concerning is the relationship between address and private key.
