International payment using the radio waves

In a first, Bitcoin developers have done something amazing amid the criticism over the lightning network and issues associated with it. A team of developers has made an international payment using the radio waves on the lightning network.

Rodolfo Novak, the co-founder of the startup CoinKite sent out a Bitcoin transaction to Bloomberg columnist Elaine Ou from Toronto Canada to San Francisco, California. The current feat is quite remarkable given how dependent our current system of banking is on the internet. So, under the circumstances of an Internet shut down, you can still send or receive Bitcoin using the radio waves

The First Step

“The journey of a thousand miles begins with a single step.”

Lao Tzu

The First step …🤔🙄🤔 Brings me back on the memory lane… In the ancient times of 2011, when I read for the first time about this BitCorn thing…

Then, I read the WhitePaper… As much or little as I understood at the time, I had a strange Sehnsucht about it and went down the proverbial rabbit hole…

Only to discover with amazement and dismay… It’s the Moria’s Mines down here…

That’s why it’s called a DYOR universe !!!

You need to Do Your Own Research folks !

It’s the only way for an Sovereign citizen !!!

Yours trully Free Spirit

Bitcoin Tree

Plant the Seed.
Make the tree grow!
You'll never enjoy it's shadow!
But you joice knowing the next generations to come,
Will thrive under it's Legacy...

Best P2P exchange to buy/sell Bitcoin

What are Peer-to-Peer Cryptocurrency Exchanges?

P2P crypto exchanges simply remove the middlemen, the core strength of Bitcoin’s design. Allowing users to buy/sell directly with each other without any trusted third-party to help carrying out transactions.

It is this 🤓 miners strong believe and best practice that privacy and security matter, then P2P exchanges will likely be a better option than the regular exchanges for handling your cryptocurrency!

Peer-to-peer bitcoin exchanges offer anonymous ways to buy and sell Bitcoin with a wide range of payment methods.


It’s no surprise that the P2P marketplaces have grown considerably in recent years.

Block 170 – First ever bitcoin transaction

2009-01-12 04:30
#1 bitcoin transaction

The first ever bitcoin transaction from one person to another, on 2009-01-12 at 04:30 used Pay-to-Public-Key (P2PK), when Satoshi Nakamoto sent coins to Hal Finney in Block 170.

P2PK is no longer used because it is a more expensive, less private, and less secure way of receiving bitcoin than other methods.

Bitcoin WhitePaper Day

Bitcoin – A Peer-to-Peer
Electronic Cash System

It’s bitcoin White Paper Day.

The mailing list was hosted by Metzdow and run by a group of cypherpunks who shared ideas on creating a kind of digital currency and payment system. Satoshi shared the whitepaper in a message that read, “Bitcoin P2P e-cash paper,” which outlined the main properties of the system.

I’ve been working on a new electronic cash system that’s fully
peer-to-peer, with no trusted third party.

The paper is available at:
http://www.bitcoin.org/bitcoin.pdf

The main properties:
Double-spending is prevented with a peer-to-peer network.
No mint or other trusted parties.
Participants can be anonymous.
New coins are made from Hashcash style proof-of-work.
The proof-of-work for new coin generation also powers the
network to prevent double-spending.

Bitcoin: A Peer-to-Peer Electronic Cash System

Abstract. A purely peer-to-peer version of electronic cash would
allow online payments to be sent directly from one party to another
without the burdens of going through a financial institution.
Digital signatures provide part of the solution, but the main
benefits are lost if a trusted party is still required to prevent
double-spending. We propose a solution to the double-spending
problem using a peer-to-peer network. The network timestamps
transactions by hashing them into an ongoing chain of hash-based
proof-of-work, forming a record that cannot be changed without
redoing the proof-of-work. The longest chain not only serves as
proof of the sequence of events witnessed, but proof that it came
from the largest pool of CPU power. As long as honest nodes control
the most CPU power on the network, they can generate the longest
chain and outpace any attackers. The network itself requires
minimal structure. Messages are broadcasted on a best effort basis,
and nodes can leave and rejoin the network at will, accepting the
longest proof-of-work chain as proof of what happened while they
were gone.

https://www.metzdowd.com/pipermail/cryptography/2008-October/014810.html

The pseudonymous Bitcoin creator disclosed that they had been working on a new electronic cash system that uses a Proof-of-Work (PoW) consensus algorithm that required no trusted third party. Although the document met mixed reactions, it was the beginning of what is known today as blockchain technology.

A couple of months after the release, the Bitcoin network was launched, with the first block mined on January 3, 2009. About eight days later, Hal Finney received the first transaction of 10 BTC from Nakamoto, after which he posted a legendary tweet that read:

In the 14 years since that day, bitcoin’s value rose from zero to a peak of $68,990 last November and was hovering above $20,000 on Monday, according to CoinDesk data. The cryptocurrency currently has a market capitalization of over $390 billion. It also inspired the creation of more than 20,000 different cryptocurrencies currently in circulation, while bitcoin remains the largest by market cap.

Over the years, several people have been rumored to be Nakamoto, including early bitcoin contributor Hal Finney, cryptographer Nick Szabo, physicist Dorian Nakamoto and even Tesla’s chief executive Elon Musk, who all denied the claims.

Satoshi’s identity is still a mystery, but Finney was well-known for his contribution to the creation of Bitcoin. He worked hand-in-hand with Nakamoto to find and fix bugs in Bitcoin’s underlying infrastructure. Before his death in 2014, Finney shared a detailed story about his journey with Bitcoin

About a year after the launch of Bitcoin, the cryptocurrency went on to record its first real-world commercial use case when a Florida man spent 10,000 BTC to purchase two large Papa John’s pizzas on May 22, 2010.

Although the coins were worth $41 at prices back then, at today’s price, the transaction is worth more than $200 million. To commemorate the event, the Bitcoin community celebrates Bitcoin Pizza Day every year on May 22.

Bitcoin’s Store of Value

To any intelligent observer, it has been apparent that bitcoin’s primary use has emerged to be store of value/investment.

Yes, bitcoin’s decentralized/permissionless solution to creating an immutable cryptographically secured database brings a vast array of different potential revolutionary applications not seen since the advent of the internet but again, the primary use has emerged to be store of value/investment.

bitcoin has been so good at this store of value thing that it has become detrimentally  successful – enter the (well-funded) hacks and puppets…attacks from the outside and from within – some of which via spread of (FUD) tangent ideas with coders, media, investors, and within bitcoin community to maybe start an idea of even ‘slight’ change.

First, please realize no other tool in modern-day finance has been so successful at being an effective savings mechanism which unlike traditional ‘savings accounts’ this bitcoin actually keeps up in value for you to be able to afford higher cost of rent, education, healthcare, vacations, etc. (due to its beautiful combination of scarcity, a ceiling of 21mill coins, immutable, permissionless->not controlled/influenced, secure, and being established/developed).

This effective savings tool of bitcoin is made accessible to the 99% of us and cuts to the core of exposing the flaw of the central bank fiat system with its funny-money creation out of thin air paper/credit-currencies benefiting the privileged institutions and then last to benefit would be the rest of us.

It can also expose flaws of fraudulent funneling of extra paper-currencies created by central banks…now think, even those privy to any fraudulent funneling of funny-money will see what’s going on and understand something like bitcoin as an alternative being effectively immune to these games that even these bad-actors themselves would buy bitcoin! Bitcoin changes the paradigm of central-bank funny-money (Bitcoin is the anti-funny-money warrior: open & mechanism)….and it has taken off….and will catch the attention of the central banks who by definition, have nearly unlimited systemic resources and influence (think governments, telecoms ISP providers, hardware/chip manufacturers, software developers, search engines, exchange conartists).

Even if a hard-fork doesn’t happen anytime in the next couple of years, it’s the threat that an attack on this pure beautiful store of value system to something even slightly different that can actually gain a noticeable percentage raises the question…is it possible that someday that the groups influencing bitcoin (those controlling mining or those involved with coding development, or the rest buy/transacting in bitcoin) would (either out of ignorance/misunderstanding or out of vested-interest to undermine bitcoin) start demanding (even slight) changes that may contradict the store-of-value that bitcoin is???

That is the big question that if the answer starts looking like yes…then value would plummet as bitcoin no longer be seen as a store of value but would eventually turn into another app coin (i.e. Ethereum) that can do many amazing things but not the one store-value amazing thing that it has done these past few years. the price would be zero-bound (compared to what we’ve been accustomed to with bitcoin today).

If the answer to that question is no (that you reading this, this community, software coders, mining operators, investors, everyday folk, work to stay educated on the above and act to keep the integrity of this bitcoin system)…then even a $50 billion market cap would still be seen as trivial in the financial assets arena where one bitcoin can easily go above $5,000 USD. But really, as the years pack on and integrity remains intact, the price would be infinity-bound.
