Understanding the Bitcoin Lightning Network
The Lightning Network is a second layer payment protocol built on top of the Bitcoin blockchain that allows for fast, low-cost transactions.
It was first proposed by Joseph Poon and Thaddeus Dryja in a white paper published in 2015.
The Lightning Network enables users to create payment channels between each other, which operate off-chain and allow for instant transactions.
These payment channels are secured by smart contracts and require both parties to sign off on any transactions that take place through the channel.
The Lightning Network was launched in 2018 and has since grown rapidly, with over 20,000 nodes and 56,000 payment channels on the network as of early 2023.
The Lightning Network is designed to be scalable, meaning that it can handle a large number of transactions without slowing down.
It is also designed to be interoperable, which means that it can work with other blockchain networks and payment systems.
One of the key benefits of the Lightning Network is that it enables micropayments, which are transactions that involve very small amounts of money.
Another benefit is that it can help to reduce the load on the Bitcoin blockchain, which can be slow and expensive to use.
The Lightning Network is still in the early stages of development, and there are ongoing efforts to improve its usability, security, and functionality. Nonetheless, it has already made significant strides in making Bitcoin and other cryptocurrencies more user-friendly and accessible to a wider audience.
The Lightning Network is a second layer protocol built on top of the Bitcoin blockchain. It aims to solve some of the scalability and efficiency issues faced by Bitcoin and other blockchain-based cryptocurrencies.
In the traditional Bitcoin network, all transactions are recorded on the blockchain, which can be slow and expensive due to the limited number of transactions that can be processed per second. The Lightning Network seeks to address this issue by allowing users to create payment channels between each other, which operate off-chain. This means that transactions can be processed much faster and at a lower cost, since they don't need to be recorded on the blockchain.
To use the Lightning Network, users first need to set up a payment channel with another user. This involves creating a multi-signature address on the blockchain, which requires both parties to sign off on any transactions that take place through the channel. Once the channel is established, users can send payments to each other instantly and with minimal fees.
For example, imagine Alice and Bob want to transact frequently with each other using Bitcoin. Instead of sending transactions to the blockchain each time they want to transact, they can set up a payment channel between them on the Lightning Network. This would allow them to send Bitcoin to each other instantly and without having to pay high transaction fees.
One of the key benefits of the Lightning Network is that it allows for micropayments, which are not feasible on the traditional Bitcoin network due to high transaction fees. This makes it possible for small transactions, such as paying for online content or tipping content creators, to be processed in a more efficient and cost-effective way.
Overall, the Lightning Network is seen as an important development in the evolution of Bitcoin and other blockchain-based cryptocurrencies. By increasing transaction speed and reducing costs, it has the potential to make cryptocurrency more accessible and user-friendly, while also improving the scalability and efficiency of blockchain networks.
Careful of the Prompts You Give Yourself
A prompt is not only what you type into a model. It is any sentence that gets inside you and starts issuing orders. Most of what we call goals were written by comparison, media, competition and now the model, and they arrive dressed as ambition. Shayne Heffernan maps how an imported sentence becomes a week, why a want should carry its source the way a Round Table claim does, and how to strip, lock and guard the objective that is actually yours.
KXCO is Enhanced Intelligence, Not Artificial
I never wanted artificial intelligence. I wanted enhanced intelligence, and they are not the same product. Artificial means the machine does the thinking and hands you the answer. Enhanced means I do the thinking, with more of my own mind in the room than I have ever had at one time. Forty years of reading, recallable in the second I need it. Patterns across law, credit, physics and markets that no specialist sees, because the useful ones sit between the fields rather than inside them.
The AI Safety Argument Is Being Held in the Wrong Room
The people who will be blamed for what AI does are not in the room where its safety is argued. A jailbreak escapes a policy. The failure that costs money is an action that escapes an owner, a payment sent or a record altered. Tokens are not authority. Intelligence got cheap and judgment did not, and there is no organ of standing you can copy into a model. Shayne Heffernan on the objection worth taking seriously, and the questions to take into a vendor meeting.
NIST Graded Our Post-Quantum Cryptography. Zero Failures.
NIST's Algorithm Validation Test System generated test vectors nobody had seen, we answered them over the ACVP protocol, and NIST graded the result: 2,130 cases across ML-KEM, ML-DSA and SLH-DSA in every parameter set offered, zero failures, demo certificate A11025. This is what that proves, where we deliberately drew the claim narrower than NIST's own matrix, and why the FIPS 140-2 sunset on 21 September makes the distinction between being graded and grading yourself worth understanding.
