Boletín de Bitcoin Optech # 117
Quote
This week’s newsletter describes a compiler bug that casts doubt on the safety of secure systems and explains a technique that can be used to more efficiently verify ECDSA signatures in Bitcoin. Also included are our regular sections with popular questions and answers from the Bitcoin StackExchange, announcements of releases and release candidates, and summaries of notable changes to popular Bitcoin infrastructure software.
Quote
US Patent 7,110,538 has expired: Bitcoin transactions are secured using ECDSA (the Elliptic Curve Digital Signature Algorithm). Verifying signatures involves multiplying points on the elliptic curve by scalars. Typically, each transaction input requires one or more signature verifications, meaning that syncing the Bitcoin block chain can require many millions of these elliptic curve point multiplications. Any technique to make point multiplications more efficient therefore has the potential to significantly speed up Bitcoin Core’s initial sync.

In a 2011 bitcointalk post, Hal Finney described a method by Gallant, Lambert and Vanstone (GLV) to efficiently compute elliptic curve point multiplications using an endomorphism on the curve (a mapping from the curve to itself which preserves all relationships between points). By using this GLV endomorphism, the multiplication can be broken into two parts, which are calculated simultaneously to arrive at the solution. Doing this can reduce the number of expensive computations by up to 33%. Finney wrote a proof-of-concept implementation of the GLV endomorphism, which he claimed sped up signature verification by around 25%.

Pieter Wuille separately implemented the GLV endomorphism algorithm in the libsecp256k1 library, which is used to verify signatures in Bitcoin Core. However, the algorithm was encumbered by U.S. Patent 7,110,538 and so to avoid any legal uncertainty, the implementation has not previously been distributed to users. On September 25, the patent expired, removing that legal uncertainty. A PR has been opened in the libsecp256k1 repo to always use the GLV endomorphism algorithm, which is expected to decrease Bitcoin Core’s initial sync time significantly.

Will the CME Bitcoin fates hole purchasers at $9,600 be left in tears?

Bitcoin cost has stayed above $10,000 for quite a while, yet will the energy tip back in the bulls favor for a retest of the key multi-year opposition at $12K?

The ongoing week has been generally dull on the value developments of Bitcoin (BTC), as a moderate upward pattern was built up after Bitcoin's value found a balance at above $10,000. This assembly at that point proceeded toward $11,000 on Sep. 18 however was pushed back by some transient opposition levels.

the noon wall report at 10:23am

Bitcoin continues trading in a narrow range around the $10.8kish area. Another strong finish yesterday near the end of the session propelled bitcoin upwards from a low of $10,636.66 close at $10,836.442 on moderate volume.
Sideways trading in this range over the short term expected to continue as we prepare to move into October.

There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, which will follow the rules of the network no matter what miners do. Even if every miner decided to create 1000 bitcoins per block, full nodes would stick to the rules and reject those blocks.

Yes that one happened on the 21st of July and is already included in the total of 1.05574581 BTC of sales that day.

Insist again and tell them that you don't agree.

I did that for a month.... Hoping to get a solid second opinion here. Or uncovering my own mistake.

If it is indeed their fault, I'll name and shame them wherever possible. Most notably here.

"God" is just a very old name for "existence".

Didn't know that, thanks. Any source/hint to dig in?

Yes, but only in german.
https://homepage.univie.ac.at/Erwin.Bader/Schoepfung_zeitlich.html

Based on an alternative translation of JHWH (Jahweh) as "I am" or "i am here (to be)".
Imho, this is also the most logical translation.
It spins around the philosophic question of origin: which was first? existence or the creator? can a creator exist without existence?

No time now to review and untangle yet another one of these, but that’s flatly implausible.

By a verbal trick, Christians converted the generic term for a class of deities to a proper noun naming a singular deity, in multiple languages:  First the Latin deus (cognate of Sanskrit devá), then eventually the English god—in Old English, so generic a word that it was originally a neuter noun distinguishable from masculine goda and feminine gyden!  Whereas if you want to know the origins of the word, it is not sensible to analyze it as a name for a singular entity.

As a precaution, I must mention that attempts to relate Hebrew to Indo-European languages are mere hokum, usually peddled by Christian evangelists—often, but not always by those of the type who claim to be descended from the mythical Lost Tribes of Israel.  Hebrew is from a completely different language family; and there is no evidence that the different language families share any common ancestor.

The word god, like German Gott, descends from Proto-Germanic, ultimately Proto-Indo-European roots antedating the Bible, and certainly from a time long before the polytheistic speakers of such languages ever read the Book of Exodus.  It seems the current theory amongst actual etymologists is that it descends from a PIE root meaning ‘to invoke’ (as by ritual), although the history of the word is obscure and somewhat vexed; a competing theory is that it descends from the root ‘to pour’ (in reference to a sacrificial libation).

N.b. that the Ten Commandments include a decree that “thou shalt have no other gods before me”, apparently a vestige from the Jewish change from polytheism to henotheism (i.e., a belief in one superior deity, above and against other existing deities; observe the god-invoking magic competition of Moses with the Egyptian priests, or the similar challenge of Elijah to the priests of Ba’al, or the Bible’s multiple prohibitions against “Asherah poles” in reference to the worship of a Semitic goddess).  That antedates the further change to monotheism (i.e., a belief that only one deity exists).

Contemporary Judaism has a cultural sensitivity (not quite a law, at least not according to most Jewish authorities) about writing the word “God”, often rendered as “G-d” or in various other forms, as a secondary effect of the Jewish law against writing the Tetragrammaton anywhere that it may potentially be defaced.  Compare and contrast the kosher law against eating meat with milk, a protection against potentially coming too close to violating the negative mitzvah against boiling a kid in its mother’s milk.

The Christian deity is not actually monotheistic in the Jewish sense.  In concept, it copies the Zoroastrian Ahura Mazda (a good god embattled by an evil god/devil) mashed together with the Hindu concept of a trinity, the concept of a divine son (here probably from Mithraism), the mortal incarnation of a god (various sources), plus a few other things.  The Jewish monotheism is closer to the Stoics’ animus mundi, and probably therefrom derived.  The notion that an angel could rebel against an absolute supreme being is, of course, illogical; accordingly, the Jewish Satan is also quite different than the Christian Satan.  The only real linkages between Judaism and Christianity are that (a) Christianity started as a religion of heretical Jews in the Second Century’s equivalent of New Age cults, and (b) Christianity takes the Jewish Bible as its Old Testament.  In particular, the Christian concept of a messiah (one-third of a three-in-one deity) is totally foreign to the Jewish concept of a messiah (a Jewish king, perforce only human, bearing an ancient title that was held by historical Jewish kings—and even granted by the Jews to one Gentile, Cyrus the Great), and is not therefrom derived.

(Side note:  The word “christ” (χριστός) is a calque of Hebrew “messiah” (משיח).  It is a title, not a name, wherefore educated Christians typically refer to “Jesus, the Christ”, not “Jesus Christ”.)



The foregoing fact-check is dashed out almost wholly off the top of my head, and with the objective detachment of a quite irreligious observer of human affairs.  I have no faith to sell you, except for the One True Revelation of the god of Bitcoin.

Quote from: nullius
....


Illogical?
Well, under the fact that i, being atheist, see only one "god" which all religions are referring to. Even multiple deity "models", it's all the same. It's a mythical attempt to explain existence. Existence is everything. Every religion is full of metaphors of it.

Thanks for the clarification with christ.
"Jesus, Christ" should also be valid then.

How are all you CoinClowns and BagHodlers doing today?   You duped enough naive people ready for your next round of the BTC ponzi scheme?

Ironic seeing you here, jonoiv.... especially a bitter no coiner like ur lil selfie, and pity the fool like you who was actually watching the BTC price in mid-March 2020 and surely had opportunities to buy back some or all of the BIG stash (.5BTC-ish) of coins that you sold at $6k-ish in April/May 2019.

Strange also that you still have hopium in current times....

I will concede that your wishes for DOWN are not impossible, but the odds seem to be growing more and more against you with the passage of time, sorry to say.. that.. sucks to be uie.

Maybe you did not get the memo?

It has been pretty rare that bitcoin prices go below its 200-Week moving average.

In April/May 2019 when you sold your BTC stash at $6k, the 200-week moving average was just getting up to $3,600, so you did have some arguable chance of being able to buy those BTC back at or below that $6k selling price, but part of the difficulty that came thereafter was a continued movement of the BTC price up through the following months.. and BTC price just continued to be reluctant to fall, even below $7,000 for any kind of meaningful amount of time.

Surely, you got a lucky break in March 2020, but you did not appreciate such lucky break.

In March 2020 BTC's 200 week moving average was merely approaching $5,500, so when the BTC price actually dipped down below that $5,500 at various times for close to a whole week - with even close to an hour below $4,400 and a few minutes dipping to $3,850, you did have a chance to buy back because admittedly, you were watching the BTC price during that time... but part of the problema was that you were waiting for more and MOre and MOAR... and more did not come.

In recent times, BTC's prices are tending to gravitate up.

We also have an issue of the longest streak ever in BTC prices closing above 10k on the daily and over 65 days now.

Furthermore, BTC's 200 week moving average is starting to approach moving up nearly $100 per week, and as I type this post BTC's 200 week moving average is getting close to $6,800 - so becoming more and more difficult for you to buy back your sold coins for anything close to your $6k-ish sales price.

If you want to get out of your no coiner status and share with some of us coiners in the hedging and other likely upcoming profits that come with HODLing bitcoin, you may need to buy some or all of those sold BTC back at a higher price than $6k prices, and seriously, the truth of the matter is that you may even have difficulties getting those coins for 4 digit prices - though surely quite a bit better odds of getting 4 digit BTC prices than hoping for anything approaching $6k and moreso below $6k.

I am thinking also that you may be better served to change your already clown-ish looking avatar, soon.

Something like the below, might be an illustrative upgrade.. - a kind of bitter and sweet all rolled into one:
