Secure Trading-CAD-interac

You have been mining for a while and now would be a nice time to cash out? You've learned enough about Bitcoin to know it's the best money out there - the first as good as gold and a lot easier to carry? How can you exchange easily with minimum hassle? Forget about the trust and feedback system. Real traders do business, not friendly chit-chat. (But you're always welcome on #bitcoin-cad on freenode.net if you want to talk.) 
In Canada you can either trade using the Over The Counter (OTC) system and its web of trust system, or register with the first Canadian-based exchange - cavirtex.com. ''
When conducting trades using the OTC you are strongly encouraged to check the rating of individuals you are about to trade with. Look for a cumulative rating of at least 8, that has come from at least 3 other individuals with good ratings, and that is at least 2 weeks old. if you do not have such a rating then you are going to have to trust the party that has a better trust rating than you until you have enough good trades and ratings to have built a good reputation yourself. 
When sending and receiving money the preferred method is a service called Interac, which has a marvellous system called Interac e-transfer. Fees are normally between 0 and 2$ per transaction (check with your bank or credit union). 
# E-mail the money (minus the password);
# Send the password by e-mail, IRC, PM on a forum, smoke messages...
(Please note it takes around 30 minutes for an Interac e-transfer transfer to be sent.)

SegWit2x

:Not to be confused with SegWit.
SegWit2x, (abbreviated B2X or S2X, and originally called SegWit2Mb), was a failed contentious hardfork attempt outlined in the New York Agreement that intended to double the block size limit. The hardfork has been denounced as an attempt made by CEOs and owners of large Bitcoin businesses to introduce changes to the currency's protocol and development cycle with ulterior motives.
Though over 80% of miners signaled intention for SegWit2x and the New York Agreement, it failed to gain any consensus among the community and Core developers. As it became clear that the execution of the fork would lead to a currency split, the address format was deliberately kept identical and no replay protection was implemented, which would have caused many BTC users to inadvertently use B2X. Additionally, code changes were made that allowed B2X nodes to pretend to be BTC nodes in order to connect and use P2P peers from the bitcoin network when synchronizing. Due to these qualities, many users considered B2X to be an outright attack on the bitcoin network, but its designers continued marketing it as an upgrade.
== Cancellation and aftermath ==
The SegWit2x hardfork was declared cancelled in a joint statement by six individuals. In the following hours, the price of B2X futures (called BT2 on Bitfinex) dropped to 1% of the price of Bitcoin (BTC, called BT1 as a Bitfinex future).
Despite the cancellation, some parties intended to proceed with the hard fork. However, when the SegWit2x nodes split from the rest of the network on November 17, it was found that they had done so one block earlier than anticipated, at block 494782. This was due to an off-by-one error as a result of counting up from the genesis block instead of from block 1. After splitting off, SegWit2x nodes were then waiting for the first block of >1MB to begin the chain fork. But the protocol rules say that the block size increase does not occur until block 494784, so because block 494783 is both required to be at most 1 MB by the original rules and greater than 1 MB by the new rules, SegWit2x had come to a permanent standstill.

Segregated Witness

Segregated Witness (abbreviated as SegWit) is an implemented protocol upgrade intended to provide protection from transaction malleability and increase block capacity. SegWit separates the witness from the list of inputs. The witness contains data required to check transaction validity but is not required to determine transaction effects.
Additionally, a new weight parameter is defined, and blocks are allowed to have at most 4 million weight units (WU). Non-witness and pre-segwit witness bytes weigh 4 WU, but each byte of Segwit witness data only weighs 1 WU, allowing blocks that are larger than 1 MB without a hardforking change.
After the successful activations of OP_CLTV and OP_CSV, SegWit was the last protocol change needed to make the Lightning Network safe to deploy on the Bitcoin network.
Because the new witness field contains Script versioning, it is also possible to make changes to or introduce new opcodes to SegWit scripts that would have originally required additional complexity to function without SegWit.
=== History and Activation ===
During 2016 and 2017 activation of segregated witness was blocked by miners for political reasons by exploiting a flaw in the BIP 9 activation mechanism.
On a technical level, the consensus rules of bitcoin are controlled by the economic majority not the miners, so the deadlock was possible to solve by creating a user activated soft fork BIP 148 where the economic majority would bypass the blocking miners and activate segregated witness on their own.
This required some coordination amongst the economic majority, but was ultimately successful, activating Segwit on Bitcoin soon after 1st August 2017.BitcoinMagazine: The Long Road to SegWit: How Bitcoin’s Biggest Protocol Upgrade Became Reality (Archived February 2021)

Setting up a secure ecommerce site

Upload a large collection of public addresses to your server, and go through them for orders. Don't host a bitcoind controlled wallet on your server, as that just creates a reason to attack your server. It also just becomes a potential attack vector if you set it up to respond to api requests.
You can use blockexplorer's api to check the balance on an address and mark it as complete and do whatever you do with your goods for paid orders. Don't recycle public addresses, just make more.
Using this fork of pywallet:
https://github.com/RobKohr/pywallet
that imports a list of private keys in a text file (option importprivkeyfile). I open a csv in excel that I created from copying a bunch of addresses from http://www.bitaddress.org. The private addresses column I save to one text file, and import it into my wallet using pywallet. The public addresses I import into a database for the server. I use mongodb, but really any database works. Here is the basic table format for the table address_pool:
| public_address - varchar
| used - boolean, default false
When I create an order, I grab a public address where used is false, and update that row to set used = true. I stick that public address in my order table with the users order info, and then show them the public address to pay to. 
Nice, simple, and secure, and doesn't require any outside payment processer looking to skim a profit off of my sales.

Shared coin

Shared Coin provides privacy for users' transactions by combining their transactions with other people's.
Shared Coin uses a technique similar to CoinJoin to make transactions private without needing to trust the Shared Coin service. A user's coins never leave their control and therefore it is impossible for them to be stolen or confiscated.
== FAQ ==
; How does it work?
Shared Coin is a method of making transactions which requires less trust in the service. Shared Coin is based on the CoinJoin concept which acts as a meeting point for multiple people to join together in a single transaction. Having multiple people in a transaction improves privacy by making transactions more difficult to analyse. The important distinction between traditional mixing services is the server cannot confiscate or steal user's coins.
; What logs are kept?
The server does not need to keep any logs and transactions are only kept in memory for a short time. However if the server was compromised or under subpoena it could be force to keep logs. If this were to happen although you haven't gained any privacy you haven't lost any either.
; Are there any fees for shared transactions?
Shared Coin is a free service however a bitcoin network fee of 0.0005 BTC is required.
; How long do shared transactions take?
Between 30 seconds to 5 minutes depending on the number of iterations.
; Is there a maximum transaction size?
The maximum transaction size is 50 BTC.
The user should also remember that Shared Coin can never completely sever the link between the input and destination address, there will always be a connection between them, it is just more difficult to analyse.

Sidechain

A sidechain or pegged sidechain enables bitcoins and other ledger assets to be transferred between multiple blockchains. This gives users access to new and innovative cryptocurrency systems using the assets they already own. By reusing Bitcoin's currency, these systems can more easily interoperate with each other and with Bitcoin, avoiding the liquidity shortages and market fluctuations associated with new currencies. Since sidechains are separate systems, technical and economic innovation is not hindered. Despite bidirectional transferability between Bitcoin and pegged sidechains, they are isolated: in the case of a cryptographic break (or malicious design) in a sidechain, the damage is entirely confined to the sidechain itself.
== Discussion ==
A sidechain is a mechanism that allows you to move your bitcoins to another, completely independent blockchain, trade them there, and they can then be moved back to main bitcoin blockchain I will try to explain how it should work:
You may have already encountered the idea of a one-way peg. This means that you destroy some BTC, and you gain some other currency for doing that. Example: when Counterparty started, people could “burn” some of their BTC by sending them to an unspendable address, and for doing it, they received newly created XCP tokens. This is called a one-way peg, and it cannot be reversed. You can only move the money one way, you cannot turn it back to BTC later.
Sidechains extends this idea, and creates a two-way peg, that lets you move it back and forth. Instead of destroying BTC by making them unspendable, you lock them in little boxes. These boxes do not belong to any address, they are instead controlled by a bitcoin script. For each box you lock this way, you get newly created tokens on the sidechain (which is another blockchain, complete separate network). You can then give these tokens to someone, pay with them, and when he wants to bring them back to the Bitcoin blockchain, he can just destroy the tokens in the same way. Providing a cryptographic proof that he destroyed the tokens will allow him to open a locked box and collect the Bitcoin.
So the value is pegged, because you can freely turn one into the other at any time.
The purpose of this trick is to allow people to safely experiment with different rules, networks and consensus mechanisms, that may be suitable for different purposes, without putting the main Bitcoin network at risk. In other words, it creates an area where you can bring some of the BTC you have, try some crazy experimental stuff, and then bring them back.https://www.reddit.com/r/Bitcoin/comments/32w9he/eli5_how_do_sidechains_work/cqfb0te/

Silk Road

Silk Road is an online market. It is operated as a Tor hidden service, such that online users are able to browse it anonymously and securely without potential traffic monitoring. All its products can be bought anonymously for bitcoins
== Products ==
As of March 2013, the site had 10,000 products for sale by vendors, 70% were drugs that are considered contraband in most jurisdictions. 340 varieties of drugs were being sold, including heroin, LSD, and cannabis. There were also legal goods and services for sale, such as apparel, art, books, cigarettes, erotica, jewelry, and writing services. A sister site, called "The Armory", sold weapons (primarily guns) during 2012 but was shut down due to a lack of demand.
== History ==
The website launched in February 2011; development had begun six months prior. It is held to be part of the Deep Web. Silk Road was operated by "Dread Pirate Roberts" (named after the fictional character from The Princess Bride), who was known for espousing libertarian ideals and criticizing regulation.
Initially, buyers could register for free, but there were a limited number of new seller accounts available; new sellers had to purchase an account via an auction. Later, a fixed fee for each new seller account was chosen to mitigate the possibility of malicious individuals distributing tainted goods.
On October 2, 2013, the FBI shut down Silk Road. They arrested Ross William Ulbricht on charges of alleged murder-for-hire and narcotics trafficking violation and identified him as the founder and chief operator "Dread Pirate Roberts." On 6 November 2013 Forbes and Vice reported that Silk Road 2.0 was online and being run by former administrators of Silk Road and that a different user was now using the name, Dread Pirate Roberts.
== Sales ==
The criminal complaint published when Ulbricht was arrested included information the FBI gained from a system image of the Silk Road server collected on 23 July 2013. It noted that, "From February 6, 2011 to July 23, 2013 there were approximately 1,229,465 transactions completed on the site. The total revenue generated from these sales was 9,519,664 Bitcoins, and the total commissions collected by Silk Road from the sales amounted to 614,305 Bitcoins. These figures are equivalent to roughly $1.2 billion in revenue and $79.8 million in commissions, at current Bitcoin exchange rates...", according to the September 2013 complaint, and involved 146,946 buyers and 3,877 vendors. According to information users provided upon registering, 30 percent were from the United States, 27 percent chose to be "undeclared," and beyond that, in descending order of prevalence: the United Kingdom, Australia, Germany, Canada, Sweden, France, Russia, Italy, and the Netherlands.
