LakeTrader

LakeTrader is an in-browser (and hence cross-platform) app launched by LakeBTC, that allows traders to view order book data, trade history and open orders, along with a number of powerful charting tools that allow both technical analysis and one-click trading.http://www.coindesk.com/lakebtc-exchange-launches-browser-based-bitcoin-trading-app/ LakeBTC Exchange Launches Browser-based Bitcoin Trading App
There are three major features on LakeTrader: Live Data, Pro Charting, and OneClick Trade.https://www.lakebtc.com/p/2644?locale=en LakeTrader, a professional trading tool
==Live Data==
LakeTrader uses an HTML5 charting library and is fully integrated with the exchange’s real-time API. In a single web page, traders can view live orderbook data, trade history, open orders, and analyze historical trade data.
==Pro Charting==
There are loads of features available – BTC/USD and BTC/CNY charts in one, five, 15, 30, 60 minute, one day and one week intervals, with styles in bars, candlesticks, lines, areas, etc. You can also draw trend lines, trend angles, pitchforks, Gann box, Fibonacci retracement, ABCD patterns, Elliott Wave subminuette, and so on.
==OneClick Trade==
The streamlined orders allowing traders to place buy and sell orders with a single click, using the 'OneClick' trade mode, simply set a default order size (e.g., 0.2 BTC) and a multiplier (e.g., ×5), traders can hover his mouse over the Orderbook and an overlay with buy/sell buttons will appear with the corresponding price. 
Just click the button and the order will be sent to our server in real time, to use this function, the trader must set a default order size and a multiplier, hover the pointer over the orderbook and an overlay with buy/sell buttons will appear with the corresponding price.

Laszlo Hanyecz

Laszlo Hanyecz (laszlo) made the first documented purchase of a good with bitcoin when he bought two Domino's pizzas from jercos for 10,000 BTC. laszlo had made contributions to Bitcoin's source code in the past.
==Pizza==
On May 17, 2010, laszlo posted a request to buy pizza with bitcoin. It was on May 22 that he reported successfully trading 10,000 BTC for two pizzas, with jercos ordering the pizza and receiving the coins. The bitcoins were quoted at $41 at the time of the offer.
===Pizza Index===
The Pizza Index is the value of the bitcoins spent on the pizzas, were they to be sold rather than spent on pizza. It started at $41 when the transaction actually occurred, and rose significantly since then, topping at $600 million in November 2021.
===Bitcoin Pizza Day===
To commemorate the transaction, May 22 is dubbed Bitcoin Pizza Day. Pizza providers worldwide offer discounts to bitcoin users to commemorate laszlo's purchase.

Lazy API

For the incredibly lazy and/or incompetent web developer, present is the lazy man's bitcoin API (copied from a forum post):
==Problem==
Lazy web designer wants to use bitcoins without dealing with installing bitcoin on a server, installing a shopping cart interface, or using ugly merchant services with callbacks.
==Solution for receiving bitcoins==
# Input a list of bitcoin receiving addresses to your database
# Give a bitcoin address to a potential customer
# Have the customer tell you when they have sent the coins and have at least 1 confirmation (you can choose a number higher than 1 if you are worried about double-spending)
# Check blockexplorer to see if they sent the right amount
# Give them what they paid for
==Risks==
===External Service===
BlockExplorer is a service that is provided by a private party. There is no guarantee that the information provided by BlockExplorer matches the blockchain.
There have not been any reports that BlockExplorer has reported transaction data incorrectly.
===Double Spending===
A merchant is exposed to a double-spending attack when recognizing a payment before it has been confirmed with a sufficient number of blocks.
For an attacker to be successful with this double spend tactic a significant effort is required and thus the risk of this attack being made against the typical retail merchant is pretty minimal. It would not be advisable for a merchant with little to no recourse against an attacker to accept payment without a sufficient number of confirmations however.
Note that this attack can be performed no matter which API or client is being used.

Libbitcoin Blockchain

The libbitcoin-blockchain library is a dependency of libbitcoin-node and libbitcoin-server. The library provides transaction and block validation as well as transaction (memory) and block (orphan) pools.
==Consensus Validation==
By default the library depends on the libbitcoin-consensus library and its use can be selected by run time configuration. This ensures that consensus checks are identical to those implemented by bitcoind. By building using the --without-consensus flag the dependency is avoided and libbitcoin native consensus checks are used instead.
==History==
* The blockchain was originally contained within libbitcoin and contained libbitcoin-database.
==Dependencies (Version2)==
* boost
* secp256k1
* libbitcoin
* libbitcoin-consensus (optional)

Libbitcoin Common

The common libbitcoin-system (formerly "libbitcoin") library is a dependency of all others with the exception of libbitcoin-consensus. It was the first library created and originally contained the core functionality of all of the others.
==Example==
 #include <cstdint>
 #include <iostream>
 #include <string>
 #include <bitcoin/bitcoin.hpp>
 
 // Extract Satoshi's words.
 int main()
 {
 const auto block = bc::chain::block::genesis_mainnet();
 const auto& tx = block.transactions().front();
 const auto& input = tx.inputs().front();
 const auto script = input.script().to_data(false);
 std::string message(script.begin() + sizeof(uint64_t), script.end());
 std::cout << message << std::endl;
 return 0;

Libbitcoin Network

The libbitcoin-network library is a partial implementation of the Bitcoin P2P network protocol. Excluded are all sub-protocols that require access to a blockchain. The libbitcoin-node library extends this P2P networking capability and incorporates libbitcoin-blockchain in order to implement a full node. The libbitcoin-explorer library uses the P2P networking capability to post transactions to the P2P network.
==Example==
 #include <future>
 #include <bitcoin/network.hpp>
 
 // Send a transaction to a single P2P node.
 int main(int argc, char* argv[])
 {
 // Decode a base16-encoded Bitcoin transaction. 
 bc::data_chunk decoded;
 if (argc < 1 || !bc::decode_base16(decoded, argv[0]))
 return -1;
 
 // Parse the decoded transaction.
 const auto tx = bc::chain::transaction::factory_from_data(decoded);
 
 // Configure the P2P network session for best performance.
 auto settings = bc::network::settings(bc::config::settings::mainnet);
 settings.outbound_connections = 0;
 settings.manual_attempt_limit = 3;
 
 // Start a network session.
 bc::network::p2p network(settings);
 
 // Declare completion signal.
 std::promise<bc::code> complete;
 
 const auto send_handler = [&complete](const bc::code& ec)
 {
 complete.set_value(ec);
 };
 
 const auto connect_handler = [&complete, &tx, &send_handler](
 const bc::code& ec, bc::network::channel::ptr node)
 {
 if (ec)
 complete.set_value(ec);
 else
 node->send(tx, send_handler);
 };
 
 // Connect to the one specified host with retry.
 network.connect("localhost", 8333, connect_handler);
 
 // Wait for completion and return result.
 return complete.get_future().get() ? -1 : 0;
 }
==History==
* The P2P protocol was originally contained within the libbitcoin library.
* In late 2014 William Swanson reorganized libbitcoin sourcesLibbitcoin network refactoring in accordance with the roadmapLibbitcoin roadmap summary agreed in Toronto earlier that year. Later sources were moved into the libbitcoin::network namespace.
* By early 2016 Eric Voskuil completed the version 3 redesign to improve reliability, performance and readability. The namespace was forked into its own repository and integrated with dependent repositories.
