NewEnglandcoin

Symbol: NENG

NewEnglandcoin is a clone of Bitcoin using scrypt as a proof-of-work algorithm with enhanced features to protect against 51% attack and decentralize on mining to allow diversified mining rigs across CPUs, GPUs, ASICs and Android phones.

Mining Algorithm: Scrypt with RandomSpike. RandomSpike is 3rd generation of Dynamic Difficulty (DynDiff) algorithm on top of scrypt.

1 minute block targets
base difficulty reset: every 1440 blocks
subsidy halves in 2.1m blocks (~ 2 to 4 years)
84,000,000,000 total maximum NENG
20000 NENG per block
Pre-mine: 1% - reserved for dev fund
ICO: None
RPCPort: 6376
Port: 6377

NewEnglandcoin has dogecoin like supply at 84 billion maximum NENG. This huge supply insures that NENG is suitable for retail transactions and daily use. The inflation schedule of NengEnglandcoin is actually identical to that of Litecoin. Bitcoin and Litecoin are already proven to be great long term store of value. The Litecoin-like NENG inflation schedule will make NewEnglandcoin ideal for long term investment appreciation as the supply is limited and capped at a fixed number

Bitcoin Fork - Suitable for Home Hobbyists

NewEnglandcoin core wallet continues to maintain version tag of "Satoshi v0.8.7.5" because NewEnglandcoin is very much an exact clone of bitcoin plus some mining feature changes with DynDiff algorithm. NewEnglandcoin is very suitable as lite version of bitcoin for educational purpose on desktop mining, full node running and bitcoin programming using bitcoin-json APIs.

The NewEnglandcoin (NENG) mining algorithm original upgrade ideas were mainly designed for
decentralization of mining rigs on scrypt, which is same algo as litecoin/dogecoin. The way it is going now is that NENG is very suitable for
bitcoin/litecoin/dogecoin hobbyists who can not , will not spend huge money to run noisy ASIC/GPU mining equipments, but still want to mine NENG at home with quiet
simple CPU/GPU or with a cheap ASIC like FutureBit Moonlander 2 USB or Apollo pod on solo mining setup to obtain very decent profitable results.
NENG allows bitcoin litecoin hobbyists to experience full node running, solo mining, CPU/GPU/ASIC for a fun experience at home at cheap cost without breaking bank on equipment or electricity.

CPU Minable Coin
Because of dynamic difficulty algorithm on top of scrypt, NewEnglandcoin is CPU Minable. Users can easily set up full node for mining at Home PC or Mac using our dedicated cheetah software.

Research on the first forked 50 blocks on v1.2.0 core confirmed that ASIC/GPU miners mined 66% of 50 blocks, CPU miners mined the remaining 34%.

NENG v1.4.0 release enabled CPU mining inside android phones.

Decentralization and Community Driven
NewEnglandcoin is a decentralized coin just like bitcoin. There is no boss on NewEnglandcoin. Nobody nor the dev owns NENG.

We know a coin is worth nothing if there is no backing from community. Therefore, we as dev do not intend to make decision on this coin solely by ourselves. It is our expectation that NewEnglandcoin community will make majority of decisions on direction of this coin from now on. We as dev merely view our-self as coin creater and technical support of this coin while providing NENG a permanent home at ShorelineCrypto Exchange.

ASIC/GPU Mining Pools
Warning to Big ASIC Miners
Due to DynDiff Algo on top of Scrypt, solo mining is recommended for ASIC/GPU miners. Further more,
even for mining pools, small mining pool will generate better performance than big NENG mining pool because of new algo v1.2.x post hard fork.

The set up configuration of NENG for scrypt pool mining is same as a typical normal scrypt coin. In other word, DynDiff on Scrypt algo is backward compatible with Scrypt algo. Because ASIC/GPU miners rely on CPU miners for smooth blockchain movement, checkout bottom of "Latest News" section for A WARNING to All ASIC miners before you decide to dump big ASIC hash rate into NENG mining.

(1) Original DynDiff Warning:
https://bitcointalk.org/index.php?topic=5027091.msg48324708#msg48324708
(2) New Warning on RandomSpike
Spike difficulty (244k) introduced in RandomSpike served as roadblocks to instant mining and provide security against 51% attack risk. However, this spike difficulty like a roadblock that makes big ASIC mining less profitable. In case of spike block to be mined, the spike difficulty immediately serve as base difficulty, which will block GPU/ASIC miners effectively and leave CPU cheetah solo miners dominating mining almost 100% until next base difficulty reset.

Israeli Lawmakers Plan to Exempt Bitcoin From Capital Gains Tax in Draft New Law (current BTC/USD price is $10,686.63)

Latest Bitcoin News:

Israeli Lawmakers Plan to Exempt Bitcoin From Capital Gains Tax in Draft New Law

HOW BITCOIN HALVING AFFECTS ITS PRICE

How Bitcoin Halving Works

https://preview.redd.it/sw73yxkkcep51.jpg?width=4501&format=pjpg&auto=webp&s=fec470c75c71ffe1a27d5c09b59d255018fddd85

Each Bitcoin block is mined every 10 minutes on average, which is approximately 144 blocks per day. The Bitcoin production decreases by half every 210,000 blocks or approximately every four years. The last halving event took place in May 2020 and Bitcoin miners currently receive block reward of 6.25 bitcoins per block. Subsequently, roughly 900 bitcoins are mined every day until the next Bitcoin halving event in 2024. This is how new bitcoins are created.

Bitcoin Halving and Price Increase

https://preview.redd.it/e75ijhcpcep51.jpg?width=1046&format=pjpg&auto=webp&s=8d88529e75b55e8309350875cd16cbe68526c7ab

Bitcoin’s inflation rate is decreasing based on the mathematical algorithm, unlike the inflation rate of fiat currencies. We expect that the lack of new supply will cause the future increased demand for Bitcoin. Besides that, Bitcoin halving has been historically an extremely positive event for Bitcoin price action. Based on the Kraken cryptocurrency exchange data, halvening kicked off Bitcoin bull runs with price appreciation of 9,000% and 3,000% in 2012 and 2016, respectively.

Next Bitcoin Halving Event in 2024

https://preview.redd.it/cbru7x9rcep51.jpg?width=1440&format=pjpg&auto=webp&s=f2b765d2a7685fad23c96ebc128b7098a9daf51e

Next Bitcoin halving event is expected in 2024, when Bitcoin block reward will be reduced to 3.125 bitcoins per block from the current amount of 6.25 bitcoins per block. This means the daily Bitcoin supply will be reduced to approximately 450 bitcoins per day from the current supply of approximately 900 bitcoins per day. We assume that Bitcoin price will continue increasing in the foreseeable future, due to the algorithmically predetermined decrease of its supply and presumably steady if not increasing demand for Bitcoin from both institutional and retail investors.

09-26 01:25 - 'Looking For 1 More Person To Join Our Trading Mastermind Group.' (self.Bitcoin) by /u/Bensetera removed from /r/Bitcoin within 0-9min

'''

Hi I am looking to fill 1 out of 5 spaces in a day and swing trading Mastermind group. For some information on Mastermind groups check out this link: [link]^¹ . The Mastermind series will be a set of 10 meetings of 1.5 hours each once a week. The series will run from the 13th of October until the 15th of December. At this stage the meetings are tentatively scheduled for Tuesdays at 6:30pm - 8pm (AEDT)

At the meetings each member of the group will get 15 minutes allocated to them to use as they wish. The goal of the meeting will be to get honest feedback and to provide accountability towards working towards your trading goals.

I have experience in running a Mastermind group not related to trading for several months. If you are interested, the requirements to join the Mastermind group will be to commit to attending the Mastermind meeting each week. It would need to be a priority in your calendar.

Some optional activities that will be organised during the series as the need for them arises are:

Group market analysis.
Discussions about fundamentals.
Deep dive into record keeping systems.
Group trade analysis.
Group learning.
Group strategy troubleshooting.
Strategy sharing.
Risk management analysis.
Occasional social / fun events.

The way the meetings and group will be organised will be with a google drive, slack and the meetings will be hosted on Zoom. We can help you get used to any of these programs, they are easy to use.

As long as you have a basic understanding of trading and reading candlestick charts I would encourage you to apply. The main thing you will need is a desire to become a full time profitable trader. If you are only testing out the idea of being a trader this group might not be for you.

Either comment below or Pm me with the below template.

Expression of interest template:

Name:

Example expression of interest:

Name: Ben.

Country: Australia.

Time Zone: AEDT (GMT+11).

How much experience you have in trading: 5 Months.

What you trade: Cryptocurrency spot and futures. Mostly BTC, ETH, ADA, LTC, ATOM, XTZ, ETC, LINK, THETA.

Additional comments: I have been trading as a team with 1 other person for the last 5 months. We have been meeting 5 days a week for those 5 months. Working together has been really beneficial for us. We hope that you will experience the same benefits that we have enjoyed.

Technical: Confidential Transactions and Their Implementation Tradeoffs

As requested by /u/estradata here: https://old.reddit.com/r/Bitcoin/comments/iylou9/what_are_some_of_the_latest_innovations_in_the/g6heez1/

It is a general issue that crops up at the extremes of cryptography, with quantum breaks being just one of the extremes of (classical) cryptography.

Computational vs Information-Theoretic

The dichotomy is between computationally infeasible vs informationally-theoretic infeasible. Basically:

Something is computationally infeasible if it could in theory be done, but you would not be able to build a practical computer to do it within the age of the universe and using only the power available in just one galaxy or thereabouts.
Something is informationally-theoretic infeasible if even if you had any arbitrarily large amount of time, space, and energy, you cannot do it.

Quantum breaks represent a possible reduction in computational infeasibility of certain things, but not information-theoretic infeasibility.

For example, suppose you want to know what 256-bit preimages map to 256-bit hashes. In theory, you just need to build a table with 2²⁵⁶ entries and start from 0x0000000000000000000000000000000000000000000000000000000000000000 and so on. This is computationally infeasible, but not information-theoretic infeasible.

However, suppose you want to know what preimages, of any size, map to 256-bit hashes. Since the preimages can be of any size, after finishing with 256-bit preimages, you have to proceed to 257-bit preimages. And so on. And there is no size limit, so you will literally never finish. Even if you lived forever, you would not complete it. This is information-theoretic infeasible.

Commitments

How does this relate to confidential transactions? Basically, every confidential transaction simply hides the value behind a homomorphic commitment. What is a homomorphic commitment? Okay, let's start with commitments. A commitment is something which lets you hide something, and later reveal what you hid. Until you reveal it, even if somebody has access to the commitment, they cannot reverse it to find out what you hid. This is called the "hiding property" of commitments. However, when you do reveal it (or "open the commitment"), then you cannot replace what you hid with some other thing. This is called the "binding property" of commitments.

For example, a hash of a preimage is a commitment. Suppose I want to commit to something. For example, I want to show that I can predict the future using the energy of a spare galaxy I have in my pocket. I can hide that something by hashing a description of the future. Then I can give the hash to you. You still cannot learn the future, because it's just a hash, and you can't reverse the hash ("hiding"). But suppose the future event occurs. I can reveal that I did, in fact, know the future. So I give you the description, and you hash it and compare it to the hash I gave earlier. Because of preimage resistance, I cannot retroactively change what I hid in the hash, so what I gave must have been known to me at the time that I gave you the commitment i..e. hash ("binding").

Homomorphic Commitments

A homomorphic commitment simply means that if I can do certain operations on preimages of the commitment scheme, there are certain operations on the commitments that would create similar ("homo") changes ("morphic") to the commitments. For example, suppose I have a magical function h() which is a homomorphic commitment scheme. It can hide very large (near 256-bit) numbers. Then if h() is homomorphic, there may be certain operations on numbers behind the h() that have homomorphisms after the h(). For example, I might have an operation <+> that is homomorphic in h() on +, or in other words, if I have two large numbers a and b, then h(a + b) = h(a) <+> h(b). + and <+> are different operations, but they are homomorphic to each other.

For example, elliptic curve scalars and points have homomorphic operations. Scalars (private keys) are "just" very large near-256-bit numbers, while points are a scalar times a standard generator point G. Elliptic curve operations exist where there is a <+> between points that is homomorphic on standard + on scalars, and a <*> between a scalar and a point that is homomorphic on standard * multiplication on scalars.

For example, suppose I have two large scalars a and b. I can use elliptic curve points as a commitment scheme: I can take a <*> G to generate a point A. It is hiding since nobody can learn what a is unless I reveal it (a and A can be used in standard ECDSA private-public key cryptography, with the scalar a as the private key and the point A as the public key, and the a cannot be derived even if somebody else knows A). Thus, it is hiding. At the same time, for a particular point A and standard generator point G, there is only one possible scalar a which when "multiplied" with G yields A. So scalars and elliptic curve points are a commitment scheme, with both hiding and binding properties.

Now, as mentioned there is a <+> operation on points that is homomorphic to the + operation on corresponding scalars. For example, suppose there are two scalars a and b. I can compute (a + b) <*> G to generate a particular point. But even if I don't know scalars a and b, but I do know points A = a <*> G and B = b <*> G, then I can use A <+> B to derive (a + b) <*> G (or equivalently, (a <*> G) <+> (b <*> G) == (a + b) <*> G). This makes points a homomorphic commitment scheme on scalars.

Confidential Transactions: A Sketch

This is useful since we can easily use the near-256-bit scalars in SECP256K1 elliptic curves to easily represent values in a monetary system, and hide those values by using a homomorphic commitment scheme. We can use the hiding property to prevent people from learning the values of the money we are sending and receiving.

Now, in a proper cryptocurrency, a normal, non-coinbase transaction does not create or destroy coins: the values of the input coins are equal to the value of the output coins. We can use a homomorphic commitment scheme. Suppose I have a transaction that consumes an input value a and creates two output values b and c. That is, a = b + c, i.e. the sum of all inputs a equals the sum of all outputs b and c. But remember, with a homomorphic commitment scheme like elliptic curve points, there exists a <+> operation on points that is homomorphic to the ordinary school-arithmetic + addition on large numbers. So, confidential transactions can use points a <*> G as input, and points b <*> G and c <*> G as output, and we can easily prove that a <*> G = (b <*> G) <+> (c <*> G) if a = b + c, without revealing a, b, or c to anyone.

Pedersen Commitments

Actually, we cannot just use a <*> G as a commitment scheme in practice. Remember, Bitcoin has a cap on the number of satoshis ever to be created, and it's less than 2⁵³ satoshis, which is fairly trivial. I can easily compute all values of a <*> G for all values of a from 0 to 2⁵³ and know which a <*> G corresponds to which actual amount a. So in confidential transactions, we cannot naively use a <*> G commitments, we need Pedersen commitments.

If you know what a "salt" is, then Pedersen commitments are fairly obvious. A "salt" is something you add to e.g. a password so that the hash of the password is much harder to attack. Humans are idiots and when asked to generate passwords, will output a password that takes less than 2³⁰ possibilities, which is fairly easy to grind. So what you do is that you "salt" a password by prepending a random string to it. You then hash the random string + password, and store the random string --- the salt --- together with the hash in your database. Then when somebody logs in, you take the password, prepend the salt, hash, and check if the hash matches with the in-database hash, and you let them log in. Now, with a hash, even if somebody copies your password database, the can't get the password. They're hashed. But with a salt, even techniques like rainbow tables make a hacker's life even harder. They can't hash a possible password and check every hash in your db for something that matches. Instead, if they get a possible password, they have to prepend each salt, hash, then compare. That greatly increases the computational needs of a hacker, which is why salts are good.

What a Pedersen commitment is, is a point a <*> H, where a is the actual value you commit to, plus <+> another point r <*> G. H here is a second standard generator point, different from G. The r is the salt in the Pedersen commitment. It makes it so that even if you show (a <*> H) <+> (r <*> G) to somebody, they can't grind all possible values of a and try to match it with your point --- they also have to grind r (just as with the password-salt example above). And r is much larger, it can be a true near-256-bit number that is the range of scalars in SECP256K1, whereas a is constrained to "reasonable" numbers of satoshi, which cannot exceed 21 million Bitcoins.

Now, in order to validate a transaction with input a and outputs b and c, you only have to prove a = b + c. Suppose we are hiding those amounts using Pedersen commitments. You have an input of amount a, and you know a and r. The blockchain has an amount (a <*> H) <+> (r <*> G). In order to create the two outputs b and c, you just have to create two new r scalars such that r = r[0] + r[1]. This is trivial, you just select a new random r[0] and then compute r[1] = r - r[0], it's just basic algebra.

Then you create a transaction consuming the input (a <*> H) <+> (r <*> G) and outputs (b <*> H) <+> (r[0] <*> G) and (c <*> H) <+> (r[1] <*> G). You know that a = b + c, and r = r[0] + r[1], while fullnodes around the world, who don't know any of the amounts or scalars involved, can just take the points (a <*> H) <+> (r <*> G) and see if it equals (b <*> H) <+> (r[0] <*> G) <+> (c <*> H) <+> (r[1] <*> G). That is all that fullnodes have to validate, they just need to perform <+> operations on points and comparison on points, and from there they validate transactions, all without knowing the actual values involved.

Computational Binding, Information-Theoretic Hiding

Like all commitments, Pedersen Commitments are binding and hiding.

However, there are really two kinds of commitments:

computationally binding, information-theoretic hiding
information-theoretic binding, computationally hiding

What does this mean? It's just a measure of how "impossible" binding vs hiding is. Pedersen commitments are computationally binding, meaning that in theory, a user of this commitment with arbitrary time and space and energy can, in theory, replace the amount with something else. However, it is information-theoretic hiding, meaning an attacker with arbitrary time and space and energy cannot figure out exactly what got hidden behind the commitment.

But why?

Now, we have been using a and a <*> G as private keys and public keys in ECDSA and Schnorr. There is an operation <*> on a scalar and a point that generates another point, but we cannot "revrese" this operation. For example, even if I know A, and know that A = a <*> G, but do not know a, I cannot derive a --- there is no </> operation between A </> G that lets me know a.

Actually there is: I "just" need to have so much time, space, and energy that I just start counting a from 0 to 2²⁵⁶ and find which a results in A = a <*> G. This is a computational limit: I don't have a spare universe in my back pocket I can use to do all those computations.

Now, replace a with h and A with H. Remember that Pedersen commitments use a "second" standard generator point. The generator points G and H are "not really special" --- they are just random points on the curve that we selected and standardized. There is no operation H </> G such that I can learn h where H = h <*> G, though if I happen to have a spare universe in my back pocket I can "just" brute force it.

Suppose I do have a spare universe in my back pocket, and learn h = H </> G such that H = h <*> G. What can I do in Pedersen commitments?

Well, I have an amount a that is committed to by (a <*> H) <+> (r <*> G). But I happen to know h! Suppose I want to double my money a without involving Elon Musk. Then:

(a <*> H) <+> (r <*> G)
== (a <*> (h <*> G)) <+> (r <*> G)
== ((a * h) <*> G) <+> (r <*> G); remember, <*> is also homomorphic on multiplication *.
== ((a * h + a * h - a * h) <*> G) <+> (r <*> G); just add 0.
== ((a * h + a * h) <*> G) <+> ((-a * h) <*> G) <+> (r <*> G)
== ((2 * a * h) <*> G) <+> ((r - a * h) <*> G)
== ((2 * a) <*> (h <*> G)) <+> ((r - a * h) <*> G)
== ((2 * a) <*> H) <+> ((r - a * h) <*> G); TADA!! I doubled my money!

That is what we mean by computationally binding: if I can compute h such that H = h <*> G, then I can find another number which opens the same commitment. And of course I'd make sure that number is much larger than what I originally had in that address!

Now, the reason why it is "only" computationally binding is that it is information-theoretically hiding. Suppose somebody knows h, but has no money in the cryptocurrency. All they see are points. They can try to find what the original amounts are, but because any amount can be mapped to "the same" point with knowledge of h (e.g. in the above, a and 2 * a got mapped to the same point by "just" replacing the salt r with r - a * h; this can be done for 3 * a, 4 * a etc.), they cannot learn historical amounts --- the a in historical amounts could be anything.

The drawback, though, is that --- as seen above --- arbitrary inflation is now introduced once somebody knows h. They can multiply their money by any arbitrary factor with knowledge of h.

It is impossible to have both perfect hiding (i.e. historical amounts remain hidden even after a computational break) and perfect binding (i.e. you can't later open the commitment to a different, much larger, amount).

Pedersen commitments just happen to have perfect hiding, but only computationally-infeasible binding. This means they allow hiding historical values, but in case of anything that allows better computational power --- including but not limited to quantum breaks --- they allow arbitrary inflation.

Changing The Tradeoffs with ElGamal Commitments

An ElGamal commitment is just a Pedersen commitment, but with the point r <*> G also stored in a separate section of the transaction.

This commits the r, and fixes it to a specific value. This prevents me from opening my (a <*> H) <+> (r <*> G) as ((2 * a) <*> H) <+> ((r - a * h) <*> G), because the (r - a * h) would not match the r <*> G sitting in a separate section of the transaction. This forces me to be bound to that specific value, and no amount of computation power will let me escape --- it is information-theoretically binding i.e. perfectly binding.

But that is now computationally hiding. An evil surveillor with arbitrary time and space can focus on the r <*> G sitting in a separate section of the transaction, and grind r from 0 to 2²⁵⁶ to determine what r matches that point. Then from there, they can negate r to get (-r) <*> G and add it to the (a <*> H) <+> (r <*> G) to get a <*> H, and then grind that to determine the value a. With massive increases in computational ability --- including but not limited to quantum breaks --- an evil surveillor can see all the historical amounts of confidential transactions.

Conclusion

This is the source of the tradeoff: either you design confidential transactions so in case of a quantum break, historical transactions continue to hide their amounts, but inflation of the money is now unavoidable, OR you make the money supply sacrosanct, but you potentially sacrifice amount hiding in case of some break, including but not limited to quantum breaks.

Winward Casino Review

One of the best trends we’ve seen in online casinos over the last couple of years is a move towards the integration of games from multiple sources at many sites. By featuring games from a number of providers, players get to experience much more variety all in one location, making it easier to find sites that truly have a selection they’re happy with.

Winward Casino is an example of a casino site that has successfully combined two gaming suites into a single package to expand their offerings. Operated by Blacknote Entertainment Group and in operation since 1998, this site has a strong track record to go along with their slots and live games, as well as a solid promotional package that can be especially rewarding for high rollers.

Slots

While Winward has used a variety of software providers over the years, they currently get a bunch of their game selection from Betsoft and Topgame as well as big brands such as NetEnt, Microgaming and Pragmatic Play, the mobile-focused software developers. That’s more than enough to get an excellent variety of slots out to their players, especially since the styles offered by those companies are very different.

If you've been playing for a while, you might be familiar with most of the software developers aboard the casino. Betsoft is known for their excellent 3D slots, each of which comes with top-notch animation, sound effects and voice acting, all of which combine to create an immersive, story-like experience.

Topgame’s selection may not be quite as visually impressive, but their titles cover a wide range of themes and play styles, guaranteeing that you’re likely to find at least a few games here that attract you.

There's plenty more to discover here. For example, Pragmatic Play, one of the industry-leading software developers known for its innovative approach has a presence at the casino with their mobile-optimized games. Equally fascinating NetEnt and Rival brands who have been serving the world's most prominent online casinos will delight you with their premium-quality virtual machines. Habanero is another brand that offers a seamless gameplay alongside world-class thrilling casino entertainment from Octopus Gaming.

All in all, Winward Casino offers a truly impressive selection with notable titles such as Jekyll and Mr. Hyde, Greedy Goblins, Weekend at Vegas, Event Horizon, Mega Gems, Vegas, Grave Grabbers, Lady of the Moon, Dice and Fire, and New Tales of Egypt.
