'''GLobal Bitcoin Stock Exchange'''

The Global Bitcoin Stock Exchange is a form of exchange that provides services to brokers and traders to trade stocks, bonds and other securities listed with the exchange.

The service provides the following featuers:

* Issue shares to raise capital
* Pay dividends to shareholders
* Put resolutions to shareholders and get their vote
* Issue and sell bonds
* Borrow from and lend to the market
* And trade all of the above with other traders on the market

==Adding Funds==

Funds for the purchase of shares comes from the user's BTC account on GLBSE.

Bitcoins sent to the user's Bitcoin address for deposit must confirm before they will show as being available. The threshold for the number of confirmations that GLBSE requires is the standard six confirmations on the blockchain.

==Withdrawing Funds==

Proceeds from sales of shares add to the user's BTC account on GLBSE. Bitcoins can be withdrawn at any time. Some withdrawals, particularly larger ones, may be delayed if the funds in the service's hot wallet is insufficient and funds from cold storage must be first made available.

==Fees==

The [https://glbse.com/portfolio/fees list of fees] can be viewed once logged in.

* New asset fee: 8.0 BTC
* Dividends fee rate: 0%
* Sell fee rate, paid by seller: 0.5%
* Buy fee rate, paid by seller: 0.5%
* Transfer fee rate, paid by seller: 0.2%

Trade fees are MAKER/TAKER, that is if you place an order, and it goes on the orderbook, then you pay 0% fee, if the order gets matched with another order then you pay the trade fee(buy OR sell fee, not both).

In short; buying and selling stocks will cost investors on average 0.25% of the amount involved for each share-transaction they do.

==History==

The service comes from the first bitcoin company BitcoinGlobal. The site entered testing phase under an internal code name before being opened with a round 3 of testing on April 27, 2011<ref>[http://bitcointalk.org/index.php?topic=6500.msg94943#msg94943 Stock Exchange testing, round 3]</ref> and launch soon after.

A version 2.0 with a vastly revamped architecture was launched on March 24, 2012<ref>[http://bitcointalk.org/index.php?topic=73910.0 GLBSE2.0 has launched!]</ref>.

Smart card wallet

2012-03-13T04:28:12Z

Realpra: /* Desired features */

This pages gathers resources for the implementation of a Bitcoin wallet on a smart card.

===Rationale===

*Computers and smartphones are target for malware. The software on a smart card can be protected.
*Smart cards do not need a battery, nor internet connection, they are robust.
*Adoption: people are already used to paying with smart cards.

===Desired features===

*no blockchain, no node; the card contains only private keys, and an algorithm to sign a transaction
*the smart card should have its own keyboard (for pin code protection) and display (to show the transaction amount)
(<- Alternative to this is the card returning, to the terminal screen, the debit amount multiplied by a number only the card holder knows which cycles from 1 to 100 to 1 incrementing by 1 each transfer - the card is locked 10 minutes if a second amount is send before a pin is typed.)
* The card holder will know pin, puk, private key and address only from when he programmed it or ordered his smart card.
*the card should implement a deterministic wallet, so that funds can be recovered if the card is lost.

===Usage scenario===

* the reading device may belong to a merchant at a point of sale; it cannot be trusted with private keys.
* the reading device is connected to a full bitcoin node; it can be trusted for getting and sending blockchain information.
* the reading device sends to the card the current balance of its bitcoin addresses. This information can be cached in the card.
* the reading device sends a bitcoin receiving address and transaction amount to the card.
* the amount is displayed by the card ; the user confirms the transaction with his pin code.
* the smart card creates a signed transaction and sends it to the reading device
* the transaction is checked and broadcast by the bitcoin node.

==Implementation steps==

===1. write a bitcoin daemon that can talk to a lightweight wallet===
*this has been done already, see for example bitcoinjs: https://github.com/bitcoinjs/bitcoinjs-lib
*See also this pull request: [https://github.com/piotrnar/bitcoin/tree/importexporttx importexporttx] can be used to broadcast the transaction
* https://bitcointalk.org/index.php?topic=28278.msg383312#msg383312

===2. write a lightweight wallet===
*wallet without blockchain, in order to test the daemon
*this lightweight wallet will be later implemented on the card
*use it to define the communication protocol between card and reading device.

update: this is done, see [[Electrum]]

===3. implement wallet on a simple smart card===

* http://www.opensc-project.org/opensc openSC : tools and libraries for smart cards.
* amadousarr.free.fr/crypto/ECDSAJAVACARD.pdf : A Software Implementation of ECDSA on a Java Smart Card
* http://www.acs.com.hk : cards, readers, development kits; no display, pincode needs to be typed on the reading device

===4. implement wallet on a smart card with display and pincode ===

list of vendors:
* http://www.nidsecurity.com/products/solution-enterprise.html (smart cards with LCD displays)
* http://www.avesodisplays.com/ (smard cards with flexible displays)
