  Bitcoin/Altcoin news
Posted by: Hugues - 2018-07-23, 07:57 PM - Forum: Bitcoin and Altcoin - Replies (6)

BlackRock, the world’s largest asset manager with $6.3 trillion under management, announced on Monday that it’s considering Bitcoin for investment purposes. The firm’s CEO, Larry Fink, said that BlackRock is putting together a team to study cryptocurrencies. 

Coinbase apparently received regulatory approval from US market regulators, the SEC and FINRA, to acquire three companies. These firms would allow Coinbase to list security tokens, such as ICOs. However, Coinbase walked back the announcement, stating that regulators have not given the official go-ahead. 

SBI Holdings, a Japanese bank, has opened the world’s first crypto exchange to be backed by a bank. The new VCtrade exchange will feature Bitcoin, Ripple, and BCH trading for Japanese Yen. 

The CEO of $24 billion hedge fund, Citadel, said during a CNBC interview that he doesn’t see the point of Bitcoin and considers it a waste of time. 
Challenging this view was Avenue Capital Group’s CEO, billionaire Marc Lasry, who told CNBC he expects Bitcoin to hit a price level of $40,000. Lasry stated that he holds roughly 1% of his wealth in Bitcoin. 

South Korean tech giant Samsung has begun accepting crypto payments in several Baltic nations via the CoPay platform. Customers in select parts of Lithuania, Latvia and Estonia will be able to buy Samsung phones and appliances online and pay using Bitcoin, Ethereum, Ripple, Litecoin, and a few other altcoins.

  ERC vs ERC223
Posted by: Hugues - 2018-07-19, 05:18 PM - Forum: Bitcoin and Altcoin - Replies (9)

As if ERC20 was not enough, the cryptoland has just seen the introduction of ERC223.

The purpose of this post is to tell you about this newly introduced token standard and explore its pros and cons whatever they are.
But before I jump straight to the explanation of ERC223, I want to give you to understand what ‘ERC’ stands for? 
ERC stands for Ethereum Request For Comments while the suffix is the unique ID number to distinguish this standard from others. Similar to the HTTP protocol for internet, the crypto world has a standard protocol for tokens to be issued on Ethereum i.e. ERC20, ERC223 or ERC721 etc.
ERC223 Token Standard
ERC223 is much like ERC20, only newer and better than the ERC20. In a nutshell, ERC223 is an improved and modified version of the ERC20.
Just like a token on Ethereum which is deemed to be called as ERC20, has to incorporate certain standards and functions in its code on Ethereum’s network, ERC223 also has certain mandatory functions that it must include while its implementation to satisfy the ERC223 standard.
I am not going into details about these functions because of its technicallity,

Just like ERC20, the ERC223 tokens also don’t have a dedicated blockchain and thus live on Ethereum’s blockchain. So in transferring ERC223 tokens, you will be required to have some Ethereum as GAS.
[b]Motivation To Make A New Token Standard[/b]
The motivation is, of course, to make continuous improvements. Below are the listed goals for the same:

  • To stop loss of tokens

So far ERC20 tokens worth in bold below have been lost (27 Dec 2017):
QTUM, [b]$1,204,273[/b] lost.
EOS, [b]$1,015,131[/b] lost.
GNT, [b]$249,627[/b] lost.
STORJ, [b]$217,477[/b] lost.
Tronix , [b]$201,232[/b] lost.
DGD, [b]$151,826[/b] lost.
OMG, [b]$149,941[/b] lost.

  • To make token transfer mechanism similar to Ether transfer.

  • To rectify the inability of handling incoming token transactions for non-supported tokens

  • To remove one step out of the two-step process of transactions that happens in a token transfer.

[b]Advantages of ERC223 Token Standard[/b]
Following are the 3 key advantages of upgrading to ERC223 standard:
  1. [b]Eliminates the problem of lost tokens[/b] which happens during the transfer of ERC20 tokens to a contract (when people mistakenly use the instructions for sending tokens to a wallet). ERC223 allows users to send their tokens to either wallet or contract with the same function transfer, thereby eliminating the potential for confusion and lost tokens.
  2. [b]Allows developers to handle incoming token transactions[/b], and reject non-supported tokens. In this case, you won’t lose the tokens as it will be refunded back to you minus the Gas, something that is not possible with ERC20.
  3. [b]Energy savings:[/b] The transfer of ERC223 tokens to a contract is a one-step process rather than 2 step process (for ERC20), and this means two times less Gas and no extra blockchain bloating. This, as a result, also lowers the transaction fees one pays for the transfer of tokens.
So you see how beneficial it is to update to an ERC223 standard from a point of view of paying fewer transaction fees and prevention of losses due to human or code errors. This is an excellent overview video of ERC223 EIP.

ERC223 tokens are backward compatible with ERC20 tokens. It means that ERC223 supports every ERC20 functionality and contracts or services working with ERC20 tokens will work with ERC223 tokens correctly.
So far, the adoption of ERC223 has not really taken off, which may be because of lack of awareness and lack of enough infrastructure to store them safely. In another situation, there is no reason why ERC223 wouldn’t be implemented in place of ERC20.
The trend, however, will change soon with the growing awareness and the infrastructure to store ERC223 develops.
So far, not a lot of wallets support ERC223 directly but Trust Wallet is one you can use. We are still far from hardware wallets such as Ledger Nano S supporting ERC223 directly.

This is a huge and very very ambitious project.
I haven't reviewed yet because it will take me a lot of time. To big, to much.
Give me some weeks to do this.

I registered but did not decide to invest yet.

If someone wants to start the review, your help is welcome.

  Brave Browser and BAT token
Posted by: Hugues - 2018-07-17, 06:44 PM - Forum: Bitcoin and Altcoin - Replies (6)

I have installed the brave browser since about 2 years.
It was a good and fast browser.
On may 31 they launched their ICO and all the BAT tokens where sold out in less than 30 seconds, worth about $36000000. I believe the fastest ICO sale ever.
If you want to download the browser, follow this referral link: https://brave.com/web625
Alsi visit https://basicattentiontoken.org/  to learn some of it.

We have JSEcoin who gives website owners the ability to earn for not advertising.
Now we have Brave who gives a new dimension to website owners who still want to advertise but on ethical bases. Blockchain based advertising.

  At the festivals with Get Protocol
Posted by: Hugues - 2018-07-11, 11:47 PM - Forum: Bitcoin and Altcoin - Replies (5)

Do you remember in the early days of this forum; I came with the idea of creating a blockchain system for the festival (music) industry.
Have a look at the website https://guts.tickets/

They have already sold more than 50000 concert tickets.
Only 33000000 coins will ever be available.

GUTS is a ticketing platform that facilitates fair-use and a good user-experience. They issue smart-tickets that are protected from anyone with bad intentions. Furthermore, there is an exchange platform that allows customers to easily resell their tickets within fixed boundaries. A GUTS ticket will never leave the system, thereby guaranteeing access to each and every customer at a fair price.
The Guaranteed Entrance Token (GET) protocol, will ensure a transparent and decentralized event- ticketing market for all to use. A true transparent ticketing revolution!

    When a ticket is bought with GUTS the ticketholder is guaranteed to enter the venue. Every ticket generates a special code for each ticketholder. No matter how many times a ticket is (re)sold.
    If something came up, ticketholders can sell their tickets via GUTS at any time. You just can’t make a profit by doing so.
    GUTS registers the ownership and the properties of the tickets in blockchain. This decentralized network makes it impossible to change the properties of a ticket, but allows ownership to be transferred honestly and transparent.
    GUTS knows who is actually attending the event, regardless of how often a ticket is resold. The result is great userdata from the actual attendees, making future promotion a breeze.
    Promoters and venues can use GUTS without having to invest in expensive scanners or other hardware. All that is needed is a smartphone.

  JSECoin ICO is open
Posted by: Carsten - 2018-07-11, 02:33 PM - Forum: Bitcoin and Altcoin - Replies (16)

If you are not signed up then use this link: JSECoin homepage

When you have signed up you can see the ICO on your dashboard. Go through the KYC and then use Metamask to purchase. See the video for instructions. 

JSECoin has their own blockchain and a link to the JSE token on the Ethereum blockchain to make it easy to buy/sell JSE on exchanges.


Quote:2) How is the coin in your blockchain attached to the smartcontract? 

We have integrated with an ERC20 token sale smart contract that enables participation in the ICO. Users will send ETH and the smart contract will automatically send the equivalent value of JSE ERC20 tokens to users wallet. Once the ICO is complete the JSEcoin token contract will be opened which will enable the tokens that you already have in the JSE platform to be sent as a JSE ERC20 token to 3rd party ERC20 compatible wallets/exchanges. Tokens sent directly to other JSEcoin accounts do not use this smart contract and these transactions are recorded in our own blockchain.

Rainbow What operating system are you using to read this site?
Posted by: Carsten - 2018-07-10, 05:20 PM - Forum: Uncategorized - Replies (4)

Statistics for this year:

1) Windows:  70.7%
2) Linux:       13%
3) MacOS:     10.5%
4) Others:     5.6%

I'm not surprised that Windows is most used. What is a bit surprising is that some are still using Windows 95 and Windows 98 but it's very few hits. Windows XP is still used by 3% of Windows users!!! Amazing and a bit crazy.

I was expecting more Mac use than seen in this statistic.
