BtcBuckets

Was an instant, online EWallet service.
An instant wallet is an online wallet that requires no password. The funds in the wallet (called a "Bucket" by the site) can be spent by any access by a person or script that knows the web address (URL) for that wallet. This URL must be kept secret then. 
Funds for a Bucket can be added using the Bucket's public address.
The aim of an instant wallet is to provide an easy method to receive, store and send small amounts of bitcoins. Though there are no limits as to how many bitcoins can be stored with each Bucket, caution is warranted specifically because there is no password required -- anyone who knows the URL can access the funds (unless the bucket is "locked".)
One typical use of a basic instant wallet is the ability to transfer the bitcoins held in the Bucket by simply providing the URL to the intended recipient. The recipient then has the ability to spend or forward on the bitcoins using the Bucket's administrator panel.
Btcbuckets offers a simplistic instant wallet but also offers Buckets with extended functionality that meet specific use cases, several of which are described on the site.
==Transactions==
Deposits to the bucket are shown after three confirmations exist in the blockchain. The amounts displayed by the website may be rounded off rather than reflect the exact amount of the transaction. The exact amount can be seen by hovering the cursor over the amount displayed.
All transactions are charged a fixed .0005 BTC fee. The fee is used to prevent denial of service attacks and cover the transmission fees used to send money on the Bitcoin network.
==History==
The announcement for when the service went live occurred on February 13, 2012BtcBuckets is live/5BTC giveaway!. For undisclosed reasons, the service stopped accepting deposits and requested that those with funds take action to withdrawPlease withdraw all funds.

Btcd

btcd is a full-node implementation in Google Go by Conformal. Its project page on GitHub says:
"It currently properly downloads, validates, and serves the block chain using the exact rules (including bugs) for block acceptance as the reference implementation (bitcoind). [...] btcd does NOT include wallet functionality and this was a very intentional design decision."
See also the btcd tag on Conformal's blog, especially the "ready for public testing" announcement.
Because BTCD uses an alternative consensus implementation, it is vulnerable to breaking consensus and fake confirmation attacks.

Butterfly Labs

Butterfly Labs was a Missouri-based company that specialized in producing Bitcoin mining hardware. The company was founded in June 2012 by Nasser Ghoseiri and Sonny Vleisides, and was headquartered in Kansas City.
Butterfly Labs became well-known in the Bitcoin industry for producing some of the first ASIC miners, which were designed specifically for processing Bitcoin transactions. This provided a major efficiency boost compared to mining Bitcoin with traditional computers or graphics processing units (GPUs).
== Lawsuit ==
Butterfly Labs faced a number of delays and controversies over the course of its history. Customers who pre-ordered mining equipment often had to wait months or even years to receive their orders, with some customers never receiving their orders at all. This led to a number of complaints from frustrated customers, and eventually culminated in a lawsuit by the US Federal Trade Commission (FTC) in 2014.
The FTC alleged that Butterfly Labs had engaged in "unfair and deceptive practices" by taking payment for pre-orders of Bitcoin mining hardware but failing to deliver the products to customers in a timely manner, if at all. The FTC sought to shut down the company and force it to refund its customers, as well as pay a penalty.
In the end, Butterfly Labs reached a settlement with the FTC in May 2016. As part of the settlement, the company was required to pay a $15,000 fine and to refrain from making any misrepresentations about its products in the future. The company's founders were also barred from engaging in any business related to Bitcoin mining or other cryptocurrencies for a period of three years.
Following the FTC settlement, Butterfly Labs effectively ceased operations. The company's website and social media accounts became inactive, and its founders moved on to other ventures.
Despite its controversial history, Butterfly Labs played an important role in the early days of Bitcoin mining. The company's ASIC miners represented a major leap forward in efficiency and helped to drive down the cost of mining Bitcoin. Today, the Bitcoin mining industry is dominated by large-scale mining operations that use even more advanced technology, but Butterfly Labs is remembered as a pioneer in the space.

CBDC

CBDC (Central Bank Digital Currency) is the final and most insidious form of fiat money, since as programmable money it allows a much higher degree of control, including geofencing, time limits, restrictions on saving, blacklisting, censorship, etc. It can potentially lead to ubiquitous law enforcement and facilitate social credit systems.
== CBDC programs around the world ==
A large number of governments around the world are working on developing a CBDC. 3 have launched. 36 are in the pilot stage and 30 are in development. These are some of the most relevant.
