Thoughts on Rizful?

using as custodial wallet, it's been very useful. Also connecting to my Zeus wallet through nwc, very thanksful for such service exists. Have not used node service yet.

Huge price difference for purchasing inbound channels. WHY?

> make an outbound

Do you mean opening a channel myself to a node instead of purchasing inbound liquidity?
Yeah, I can do that, but I was just curious about the rationale behind the pricing differences.

I noticed a pretty big price difference when renting inbound LN channels by providers such as Megalithic and LNBIG.

Same inbound ~1.5M sats channel, but Megalithic asks for around 20,000 sats while LNBig asks for around 3,500 sats, that’s almost a 5-6× difference. 

Is it because Megalithic is more of a reputable and premium channel provider? while LNBig is more temporary or disposable?

How do people actually decide pricing in this market?

Would regular Bitcoin transactions remain unaffected by BIP444-related reorgs?

Thk. Then there should be no concern as long as people proceed with standard transactions

>actually modify your Bitcoin client to accept the nonconformant transactions, the result will be that any Bitcoin you hold will be slowly (or perhaps not so slowly, depending on your use habits) replaced by worthless scam-Bitcoins

this fork maybe a scheme to ensure only regular transactions are propagated.

I am still learning Bitcoin, and I’m trying to understand the practical impact of BIP444(in case it happens). From what I gather, BIP444 mainly restricts arbitrary data in scripts (like OP_RETURN or Ordinals, inscriptions), but doesn’t touch standard transaction formats such as P2PKH, P2WPKH, or Taproot(key path spending(?))

So heres my question:
If a transaction doesn’t use OP_RETURN or any nonstandard script types, it should still be considered valid under both the old and new consensus rules. That means such “normal” transactions could exist in both mempools (of nodes that follow BIP444 and those that don’t) and wouldn’t cause reorg-related issues even in a mixed network.

Am I thinking about this correctly in that standard transactions are effectively immune to any BIP444-induced reorgs because they sit in the **intersection** of both rule sets with high enough fees?

When multiple blocks are mined at nearly the same time, only one is added to the main chain while the others become stale blocks.

How do you construct mixed input transaction

coinbin seems i can download the source code and use it as offline. anyway, the most appropriate way seems using python library above..

thanks!! is this library suitable for real mainnet usage??

I’m learning Bitcoin.
I looked at this [transaction](https://blockstream.info/tx/177dcf62211e847163dca88923e829c63bbfdbeb454b1b178ce6a2652fc7c590), it uses P2WSH and P2SH-P2WSH as inputs.

How do I create a transaction like that?
I saw Coinb.in has a manual raw-transaction builder that lets you enter inputs and outputs manually, can I use that?

nLocktime.. is hard fork inevitable?

is the hard fork inevitable in 2016??? that's frustrating..

why satoshi did not leave enough space for this... like u128 and compact form..

Reading this [guide](https://learnmeabitcoin.com/technical/transaction/locktime/), from learnmeabitcoin.com about locktime, i just learned that there's last 4bytes data in transaction,  LockTime, only treats values below 500,000,000 as block heights.
Since we are at block 917584 now, so to reach 499,999,999 it’ll take… roughly 9,486 years..

After that, we won’t even be able to set block-based timelocks.
is hardfork inevitable to re-enable to setup block based nLocktime?

I’m kinda scared we’ll need a hard fork in the future...
