Technical: Upcoming Improvements to Lightning Network

Price? Who gives a shit about price when Lightning Network development is a lot more interesting?????
One thing about LN is that because there's no need for consensus before implementing things, figuring out the status of things is quite a bit more difficult than on Bitcoin. In one hand it lets larger groups of people work on improving LN faster without having to coordinate so much. On the other hand it leads to some fragmentation of the LN space, with compatibility problems occasionally coming up.
The below is just a smattering sample of LN stuff I personally find interesting. There's a bunch of other stuff, like splice and dual-funding, that I won't cover --- post is long enough as-is, and besides, some of the below aren't as well-known.
Anyway.....

"eltoo" Decker-Russell-Osuntokun

Yeah the exciting new Lightning Network channel update protocol!

Advantages

Myths

Disadvantages

Multipart payments / AMP

Splitting up large payments into smaller parts!

Details

Advantages

Disadvantages

Payment points / scalars

Using the magic of elliptic curve homomorphism for fun and Lightning Network profits!
Basically, currently on Lightning an invoice has a payment hash, and the receiver reveals a payment preimage which, when inputted to SHA256, returns the given payment hash.
Instead of using payment hashes and preimages, just replace them with payment points and scalars. An invoice will now contain a payment point, and the receiver reveals a payment scalar (private key) which, when multiplied with the standard generator point G on secp256k1, returns the given payment point.
This is basically Scriptless Script usage on Lightning, instead of HTLCs we have Scriptless Script Pointlocked Timelocked Contracts (PTLCs).

Advantages

Disadvantages

Pay-for-data

Ensuring that payers cannot access data or other digital goods without proof of having paid the provider.
In a nutshell: the payment preimage used as a proof-of-payment is the decryption key of the data. The provider gives the encrypted data, and issues an invoice. The buyer of the data then has to pay over Lightning in order to learn the decryption key, with the decryption key being the payment preimage.

Advantages

Disadvantages

Stuckless payments

No more payments getting stuck somewhere in the Lightning network without knowing whether the payee will ever get paid!
(that's actually a bit overmuch claim, payments still can get stuck, but what "stuckless" really enables is that we can now safely run another parallel payment attempt until any one of the payment attempts get through).
Basically, by using the ability to add points together, the payer can enforce that the payee can only claim the funds if it knows two pieces of information:
  1. The payment scalar corresponding to the payment point in the invoice signed by the payee.
  2. An "acknowledgment" scalar provided by the payer to the payee via another communication path.
This allows the payer to make multiple payment attempts in parallel, unlike the current situation where we must wait for an attempt to fail before trying another route. The payer only needs to ensure it generates different acknowledgment scalars for each payment attempt.
Then, if at least one of the payment attempts reaches the payee, the payee can then acquire the acknowledgment scalar from the payer. Then the payee can acquire the payment. If the payee attempts to acquire multiple acknowledgment scalars for the same payment, the payer just gives out one and then tells the payee "LOL don't try to scam me", so the payee can only acquire a single acknowledgment scalar, meaning it can only claim a payment once; it can't claim multiple parallel payments.

Advantages

Disadvantages

Non-custodial escrow over Lightning

The "acknowledgment" scalar used in stuckless can be reused here.
The acknowledgment scalar is derived as an ECDH shared secret between the payer and the escrow service. On arrival of payment to the payee, the payee queries the escrow to determine if the acknowledgment point is from a scalar that the escrow can derive using ECDH with the payer, plus a hash of the contract terms of the trade (for example, to transfer some goods in exchange for Lightning payment). Once the payee gets confirmation from the escrow that the acknowledgment scalar is known by the escrow, the payee performs the trade, then asks the payer to provide the acknowledgment scalar once the trade completes.
If the payer refuses to give the acknowledgment scalar even though the payee has given over the goods to be traded, then the payee contacts the escrow again, reveals the contract terms text, and requests to be paid. If the escrow finds in favor of the payee (i.e. it determines the goods have arrived at the payer as per the contract text) then it gives the acknowledgment scalar to the payee.

Advantages

Disadvantages

Payment decorrelation

Because elliptic curve points can be added (unlike hashes), for every forwarding node, we an add a "blinding" point / scalar. This prevents multiple forwarding nodes from discovering that they have been on the same payment route. This is unlike the current payment hash + preimage, where the same hash is used along the route.
In fact, the acknowledgment scalar we use in stuckless and escrow can simply be the sum of each blinding scalar used at each forwarding node.

Upcoming Updates to Bitcoin Consensus

Price and Libra posts are shit boring, so let's focus on a technical topic for a change.
Let me start by presenting a few of the upcoming Bitcoin consensus changes.
(as these are consensus changes and not P2P changes it does not include erlay or dandelion)
Let's hope the community strongly supports these upcoming updates!

Schnorr

The sexy new signing algo.

Advantages

Disadvantages

MuSig

A provably-secure way for a group of n participants to form an aggregate pubkey and signature. Creating their group pubkey does not require their coordination other than getting individual pubkeys from each participant, but creating their signature does require all participants to be online near-simultaneously.

Advantages

Disadvantages

Taproot

Hiding a Bitcoin SCRIPT inside a pubkey, letting you sign with the pubkey without revealing the SCRIPT, or reveal the SCRIPT without signing with the pubkey.

Advantages

Disadvantages

MAST

Encode each possible branch of a Bitcoin contract separately, and only require revelation of the exact branch taken, without revealing any of the other branches. One of the Taproot script versions will be used to denote a MAST construction. If the contract has only one branch then MAST does not add more overhead.

A reminder of who Craig Wright is and the benefits to BCH now he has gone.

This needs to be repeated every so often on this subreddit so new people can understand the history of the fork of BCH into BCH and BSV
From Jonald Fyookball's article
https://medium.com/@jonaldfyookball/bitcoin-cash-is-finally-free-of-faketoshi-great-days-lie-ahead-bb0c833e4c5d
Craig S. Wright (CSW) leaving the Bitcoin Cash community is a wonderful thing. This self-described “tyrant” has been expunged, and now we can get back to our mission of bringing peer-to-peer electronic cash to the world.
The markets will rebound when they see the chaos is over, but regardless of the price, we will keep building. Nothing will stop the sound money movement. Calling Out Bad Behavior
As Rick Falkvinge recently explained, there is a difference between small-minded gossiping about personalities and legitimately calling out bad behavior.
CSW’s bad behavior must be called out, because he has done tremendous damage to Bitcoin Cash (and possibly even the entire cryptocurrency sector).
The brief history is that he gained his reputation by claiming to be Bitcoin’s creator (Satoshi Nakamoto). He said he would provide “extraordinary proof” but he has never done so.
Supposedly, he did some “private signings” to a few people, and this allowed him to gain influence in the BCH community. The destruction he has been causing was not widely recognized until after a huge mess had been made.
Thanks to u/Contrarian__ for the following compliation of CSW’s misgivings:
Some background on Craig’s claim of being Satoshi, for the uninitiated:
He faked blog posts He faked PGP keys He faked contracts and emails He faked threats He faked a public key signing He has a well-documented history of fabricating things bitcoin and non-bitcoin related He faked a bitcoin trust to get free money from the Australian government but was caught and fined over a million dollars. 
And specifically concerning his claim to be Satoshi:
He has provided no independently verifiable evidence He is not technically competent in the subject matter His writing style is nothing like Satoshi’s He called bitcoin “Bit Coin” in 2011 when Satoshi never used a space He actively bought and traded coins from Mt. Gox in 2013 and 2014 He was paid millions for ‘coming out’ as Satoshi as part of the deal to sell his patents to nTrust — for those who claim he was ‘outed’ or had no motive 
Caught Red Handed Plagiarizing
No respectable academic, scientist, or professional needs to stoop so low as to steal and take credit for the work of others — least of all Satoshi. Yet, CSW has already been caught at least 3 times plagiarizing.
His paper on selfish mining has full sections copied almost verbatim from a paper written by Liu & Wang. His “Beyond Godel” paper which purports to claim that Bitcoin script is turing complete, is heavily plagiarized. A paper on block propagation was blatantly and intentionally plagiarized. 
Can’t Even Steal Code Correctly
CSW was also caught attempting to plagiarize a “hello world” program (the simplest of all computer programs).
He apparently does not understand base58 or how Bitcoin address checksums work (both of these are common knowledge to experienced Bitcoiners), and has made other embarrasing errors. So How Did Such an Obvious Fraud Gain So Much Power and Influence?
There are no easy answers here. It seems that as humans, we are very susceptible to manipulation and misinformation. The greatest weapon against sinister forces is a well-educated populace. This is something that can only improve over the long run.
The “Satoshi factor” is a powerful one and appeals to the glamorization of a mythical figure. Even people such as myself, who are technically astute, gave CSW all benefit of the doubt until the evidence staring us in the face could no longer be denied.
The seduction of the BCH community was also facilitated by CSW becoming a strong advocate for the on-chain/big-block scaling movement at a time when the community was dying to hear it. This message, delivered with a brazen, in-your-face style, was a sharp contrast to anything seen before.
In addition, CSW was able to find obscure topics (“2pda”), network topology, etc, that seemed to establish him as an expert with esoteric knowledge above and beyond anyone else. Basically, he was using technobabble, but it wasn’t immediately obvious except to very technical people… who were then attacked and discredited.
Eventually, as more and more of the community began to realize his technical claims were bogus, CSW banned those people from his twitter feed and slack channel, leaving only a group of untechnical “believers”, which the larger BCH community referred to as “the church” AKA the Cult-of-Craig.
Finally, if some believed that CSW possesed Satoshis’s stash of 1M BTC, then they may have been gnawing to get a piece of it. But it may turn out that these are the coins that never were. Broken Promises
If this article so far seems like an “attack piece” on CSW, remember it is important to get all the facts out in the open. We’ll get to the silver lining and bright future in a moment… but let’s continue here to “get it all out”.
One of the biggest ways that CSW has damaged the community is to make an endless series of broken promises. This caused others to wait, to waste time on his unproven ideas and solutions, and to postpone or drop their own ideas and initiatives.
He said he was building a mining pool to “stop SegWit” He said he was bringing big companies to use the BCH chain He said that he was providing a fungibility solution based on blind threshold signatures He said he was providing novel technology based on oblivious transfers He said he was providing a method where people could do atomic swaps without using timelocks He said he was going to show everyone how we can do bilinear pairings using secp256k1 He said he was going to release source code for nakasendo He said he was releasing some information that would “kill the lightning network” He said he was going to show everyone how the selfish mining theory is wrong He said he was going to show everyone how we can tokenize everything in the universe squared He said a few times “big things are coming in 2 months” 
How CSW Has Damaged the BCH Community
In addition to the broken promises, the BCH community was wounded due to:
The division of the community (with classic divide and conquer tactics) Loss of focus. Huge amounts of drama and distraction from building and adoption Investor confidence has been shaken due to uncertainty and chaos. BCH is a laughing stock to outsiders due to CSW’s antics Gemini deployment of BCH and other rollouts paused Loss of developer talent due to toxic and abrasive personality Various patent and legal threats 
The Hash War Event and Split into BitcoinSV
Every 6 months, BCH has a scheduled network upgrade. This is technically a “hard fork” but a non-contentious fork does not result in a split of the chain — it is simply new network rules being activated.
Bitcoin Cash has multiple independent developer groups including Bitcoin ABC, Bitcoin Unlimited, Bitcoin XT, Bitprim, BCHD, bcash, parity, Flowee, and others.
The nChain group, led by CSW, introduced an alternate set of changes a week before the agreed cut-off date, intentionally causing a huge controversey. These changes were incompatible with the changes being discussed between the other groups.
nChain objected to the changes being proposed (cannonical transaction ordering) despite specifically agreeing to it almost a year earlier. The last minute objections were in my opinion, an attempt at sabotage.
An emergency meeting was held in Bangkok to attempt to resolve the differences between the nChain group and the rest of the community. Not only did CSW refuse to listen to the other presentations, he walked out of the meeting after his own speech had been given. The other nChain people refused to discuss the technical issues.
After this, nChain built their own software (“BitcoinSV”) to attempt to compete for the Bitcoin Cash network. But rather than split off to follow their own set of rules, they threatened to attack Bitcoin Cash.
Their attitude was “you follow our rules or we burn it all down”.
The CSW sycophants adopted a strange interpretation of the Bitcoin whitepaper and proselytized the idea that if nChain could “out hash” everyone else, the market should be obliged to follow them.
This faulty thinking was eloquently debunked by u/CatatonicAdenosine. As it turns out, nChain was unable in any case to win at their own game. But Here’s the Obviously Good News…
CSW is gone. It’s over.
He can do whatever he wants on the BitcoinSV chain. He will never be allowed to influence Bitcoin Cash again. And all the negative things and negative people that were a consequence of his involvement in Bitcoin Cash are gone with him.
As a community, we will redouble our efforts and get back to our mission of peer-to-peer electronic cash. We will learn to work together better than ever, and we will learn to detect and punish bad behavior sooner.
The attempted attacks with hashpower also sparked innovation and a focus on the problem of how to stop such attacks in the future. This is only making Bitcoin Cash (BCH) and the entire class of Proof-of-Work coins stronger.
Nothing will stop us.
The reason why millions of dollars were spent to attack and also to defend Bitcoin Cash is because it’s something truly worth fighting over.
It’s sound money.
It’s permissionless.
It’s what Satoshi Nakamoto wrote about in 2008. It’s Bitcoin, a Peer-to-Peer Electronic Cash System.

More technical/newbie posts, less memes, please

I'm lurking litecoin, bitcoin and similar subreddits for months now, and noticed they are now FILLED with unimportant, secondary stuff like memes, price speculations etc. The technology behind the actual thing is put aside.
I'm really excited about the crypto space and as a person with technical, but not cryptography background I'm in search of information. This subreddit is often cited as a good source of it, and you can actually find it at some point, but it is buried beneath a fuckton of unimportant, yet still massively upvoted stuff.
Why I think price speculation posts are unnecessary on this sub? Because 1. Three is litecoinmarkets for that 2. It's always the same posts all over again: when price is going up -> hype posts, brag posts, memes; when price is going down -> "just hodl" posts, "it's ok, we're still up X% this month" posts, "buy the dip" posts 3. Don't you think this platform can do better?
But really, if you believe this technology is revolutionary, that it will disrupt current models in financial and many other sectors, that IT IS THE FUTURE, that it is better than fiat money, why focus so much on the amount of that same fiat money which gets you 1 LTC/BTC? Why the memes, why don't we try to provide a platform that will help it's adoption by providing a constructive, informative environment?
The current situation is mostly hype, jumping-on-the-bandwagon, get-rich-quick investors. Though the growing investor number helps mainstream adoption and getting attention from the big players, not-enough-educated community isn't sustainable long term.
My suggestions on the types of posts which I would love to see upvoted and created more:
a) Technical background discussions. I would love to see more crypto experts discussing the technical issues litecoin currently faces, possible solutions and their respective arguments, already implemented solutions and why they were chosen. Things like why the secp256k1 elliptic curve, and not some other curve, how the private key -> public key conversion really works, how exactly nodes emit the transaction to the whole network, pros and cons of on-chain and off-chain scaling, lightning network, who are our core developers, stuff like that.
As we want our cryptocurrency to be a trustless solution, we need to share the information about the intricates of the system so that less people would just follow the system blindly.
Sure, bitcoin's official wiki is a nice resource as litecoin is largely based off of bitcoin, but it isn't a place for discussion and up-to-date litecoin/bitcoin differences are poorly documented (litecoin.info is down, forum.litecoin.net is down, litecointalk.io is down).
b) Newbie tips and tricks. A lot of newbies tap in the dark. They need services that are trusted and have a stable user base. They need to know what to expect from this whole journey, especially what are the possible downsides. They need tricks like Coinbase to GDAX migration for lower fees. And they shouldn't have to dig through the meme posts to find them.
c) Litecoin competitors. Who are we competing with? What do we do better? What can we do betterer :) ? What are our limitations, and what litecoin IS NOT?
TL;DR This platform has a great unused potential to help litecoin adoption and progress, yet somehow the unimportant stuff gets to the top. We can do better. Let's start now!

Decentralized applications on TERA platform

Decentralized applications on TERA platform

Implementation of blockchain technologies provided a solution that allows to refuse of use of central servers for storing the database and to entrust them to a distributed registry. For the first time it was implemented through the example of digital currency – Bitcoin. Then enthusiastic programmers, who focused their attention on the opened opportunities, went further. They began to implement their ideas and supply new tools, laying the foundation for the digital system of the future. In such a way, smart contracts and decentralized applications appeared, presented to the user as software products for wide variety of spheres: business, entertainment, communication… Virtual blockchain began to obtain visual outlines.

https://preview.redd.it/utjl7ervb9u21.jpg?width=1080&format=pjpg&auto=webp&s=46f4ce45dbf1a3f3d84be8b027ebf10fb3374c30

Leaders in creation DApps

Ethereum became the first blockchain project that allows the creation of smart contracts and DApps.
But programmers faced difficulty - low transaction speed, which was limited to 20 tps. In 2017, EOS and TRON acted as projects that found a solution. They collected millions with the help of ICO and drove by roadmap.
On the one hand, indeed, the shown speed was significantly different and gave the opportunity to develop DApps (TRON - 1200 tps, EOS - 4000 tps). Although Ethereum took the lead in the number of created in its blockchain applications, taking a head start in two years, the competitors who appeared on the market began to drain-away developers to their platforms. For April 2019 EOS ranks the first in the number of unique users (171k) and transaction volume ($ 3 bln), TRON - the second (71k, 600 mln). This is despite the fact that more DApps allocated in Ethereum. The only thing is that transaction rate both TRON and EOS was obtained detriment of decentralization. Both projects work on the PoS consensus algorithm, and this is already a reason not to consider them decentralized. As for Ethereum, its blockchain with each fork also gradually moves towards the final transition to the PoS consensus. While the main developers justify their actions by that the PoW algorithm has already outlived itself and the distributed registry running on such a consensus cannot provide the characteristics, necessary for full-fledged DApps functionality.
That is not so!

Attractive advantage of TERA

In 2018 the TERA Foundation blockchain project was launched, which proved that it is too early to throw PoW into the past, if only because it copes brilliantly with security issues.
The author of TERA Yuri Ivanov by combining the sha3 and secp256k1 encryption algorithms in cryptography achieved excellent results, guaranteeing 1,000 transactions per second. And the architecture features of the TERA blockchain have higher capabilities - 5,000 tps. Moreover, this speed is not the limit, but without a network load test it’s early to talk about other numbers for the moment.
Anyway, we already see that currently provided speed allow the creators of DApps to embody their ideas. Language of smart contracts JavaScript facilitates the challenge. Some developers together with the creator of TERA did not waste time and for a relatively short time period of the platform’s existence placed into its space a number of really decentralized applications, that are now available to all wallet owners.

What DApps are on the TERA platform

So, what is currently available for use to members of the TERA community?

https://preview.redd.it/bf7o1dk6c9u21.jpg?width=1080&format=pjpg&auto=webp&s=3df9247705396f59b08155462029f65c5a1303b0
TERA decentralized exchange and a multi-currency wallet
The first decentralized platform for the cryptocurrency exchange is already in operation.
To be honest, for the present is only in one, but the most important direction - TERA / BTC.
Meaning that those who wish to purchase a coin can use the sellers' offers, placed on the platform, without turning to other exchanges where TERA has already passed listing.

https://preview.redd.it/69nclntcc9u21.jpg?width=1080&format=pjpg&auto=webp&s=354b5175186e5e684146cde489a02db0824a823f
Upon that, thanks to the latest update you can create a BTC account that will be bound to the main one. For sure increasing the number of cryptocurrencies for both trade and storage will increase the attractiveness. However, this is just a question of time and monitoring with what time intervals updates are released there is a confidence that it will not take long to wait. Moreover, to the topic of wallets and coins it pays to add that TERA allows you to issue your own tokens.

Services for business
Special attention is given to decentralized applications that help to conduct business activities and other dealings. For example, DApp "Promise" is available. By activating a smart contract the seller fixes his obligations with a bounded frozen account without money. The buyer studies the conditions and if they are suitable for him, he transfers the specified amount. Then goods are forwarded, or services are being provided. When deal is fulfilled, the buyer defrosts the seller’s account with the payment received. In case of refusal, the case is regarded by the escrow - the creator of the smart contract.

https://preview.redd.it/y8mp33tkc9u21.jpg?width=819&format=pjpg&auto=webp&s=28e7479c77264658a07ec5768d351cc7f4f8ddc9
There is a DApp "Frozen", where you can freeze funds on your own account until the specified date or until a specific block is generated.
A great way to avoid money wasting and to hodl some coins for a desired period.
Other applications are in the planning stage, that will facilitate business processes conducting on the blockchain directly between the parties, without intermediaries.

Gambling
Gambling admirers comprise a third of decentralized applications users. Therefore, among the DApps hosted on the TERA blockchain, entertainment from this area began to appear. There are a double bet game, a lottery and a one-armed bandit (slot machine). The slot machine evokes associations with the very first mechanical gambling machine of 1905.
It also has 3 drums and one pay line. But the functionality allows you to win the bonus round with 5 free spins and increased prize payout. Yet truth be told, you should be careful.
Personally, I’ve got the combination giving the jackpot x 200 bets, but as I later noticed the winning did not arrive in the account. Therefore, record the evidence of such things just to be on the safe side.

https://preview.redd.it/whioug4qc9u21.jpg?width=467&format=pjpg&auto=webp&s=b3f571ea0512678817bb7d31059fffcd816729a7
By the way, after the post about these errors in Discord (https://discordapp.com/invite/CvwrbeG), the reply followed immediately. The reason was that for the convenience of the player the slot does not wait for 8 seconds, which are necessary for the blockchain to confirm the block, but returns results earlier. But if there is a case of a lost block, an error occurs, where diamonds symbols are shown on the drum.
It was reported about the immediate update of the client version with the corrected drawbacks of previous one.

Online shop
The platform operates an online shop with toys on the game Minecraft subject. For TERA coins you can get soft toys, souvenirs and other goods with the next day delivery in Moscow and within 5 days to other cities of the Russian Federation.
But it will be no difficulty for other salesmen to join and offer their product range. Creating an online store does not require much time, cost or special efforts. It will take several minutes between the decision to open the goods sales point on a decentralized TERA platform and fully realized project. It is enough to load feed with an assortment and prices. Moreover, all data is stored on the blockchain, which excludes needs for hosting.

https://preview.redd.it/crh2an11d9u21.jpg?width=1000&format=pjpg&auto=webp&s=806c3d73766b9a212c1c3d15ed2d82d3cdb402a5
The buyer studies the product and if finds something interesting for himself, makes an order. A clear interface with a full functional basket is available to fulfill the order.
Payment is commission-free. The seller observes the process through the admin panel, which informs him about the state of affairs and reports the change of good statuses during all stages - from the moment of adding to the basket to delivery to the buyer.
The money paid for the goods is reserved on the buffer account at first and only after the buyer receives his order, the seller receive the amount of money to his account.

Other DApps
The first resources for communication appeared on the decentralized platform. This is a forum and dating chat.
Arcade games started to come in, like Floppy Birds. This game already was able to prove that for a poor little bird it’s so difficult to fly, even in the blockchain space!
Especially when the flight takes place in the neighborhood of a virtual industrial town, where there are more pipes than trees, and they grow right before our eyes (in the truest sense of the word!)

https://preview.redd.it/q071t2h8d9u21.jpg?width=1080&format=pjpg&auto=webp&s=8727324d966753ee57c323bd57ace6c6f07d3c27
Once again, I would like to remark that all this is really decentralized, it works and TERA is waiting for new developers, those who want to distribute and monetize their software products free, and what is more, in the most popular programming language – JavaScript.

What else would be nice to see on TERA

Virtual soil of TERA is just beginning to put out shoots of the first planted digital seeds, and in the blockchain space there is enough space for the flight of imagination when creating DApps. I will give as an example just the first that comes to mind, as well as taken from the statements of members of the TERA community on Discordapp.com.
Thus, would be great to see:
- platform for trading binary options, for a start at least on the same pair of TERA / BTC;
- browser for work with DApps and recommendations for building applications;
- a service for voting on the blockchain would provide transparency into the system of election in any sphere (such a proposal was received at Eurovision-2019, why not create it on TERA);
- author's rights patenting services for works of art, inventions and other intellectual property;
- a full-fledged forum where comments would be saved and could not be deleted (the foundation of such an application has already been laid);
- chess, backgammon, bingo, durak and other classic games;
- more games! Strategies, shooter games, exploration games... Suggest to take a deeper look to the hits of the 80s and 90s. Could be found what to remember and transfer to the decentralized platform TERA;
- fully functional casino with a wide range of entertainment: 3-line and 5-line Slot games, roulette, blackjack, poker, bets and other services of gambling industry;
- and so on and so forth.
If such ideas do not come to developers’ mind, feel free to contact the author of this article and he will share his own in the field of gaming and gambling, and help with their realization with the creative approach!
In the long run, what we need for everyday life? Tools to make money and ways to spend it.
The unique features of TERA blockchain make it possible to place both in it.
Plus they will be independent of any central administration and free of censorship.
To inspire developers for actions, the Chinese TERA community announced a contest with a prize fund of 165,000 coins.

https://preview.redd.it/ksrxovbbd9u21.jpg?width=720&format=pjpg&auto=webp&s=c2f16e877b7dac0cf2b4ef0bb249f98c0c6d0396
Those who are interested in placing their DApps on TERA will be helped by DApp Paper - https://docs.google.com/document/d/10yXAKxaU7YgrQnbdXu_L7WWovUoRtdJwo3tXXaGZGSQ/edit
And a couple of words to the developers: You can choose TRON platform, you can choose EOS or Ethereum. But what are your priorities? All these systems are in the hands of corporate owners, which leads away from decentralization. And those who want to get away from totalitarian control and give the fruits of their creativity complete freedom should consider the TERA platform.
The TERA Foundation website has a page with a special world map. It shows in real time how many full nodes support the blockchain operation- https://terafoundation.org/map.html. To be among the first means to participate in laying the foundation, that is able to withstand a powerful boost to the rapid development of future technologies. If there is no your city on the map, only a few minutes separates you from correcting it. Instructions for node installation will help to join the TERA community and make your contribution right now.
It can be found here: https://sourceforge.net/p/tera/code/ci/mastetree/README.md

https://preview.redd.it/zcq5ijbgd9u21.jpg?width=1246&format=pjpg&auto=webp&s=a3cdd4219a5904a89f5de59413d45d6769b07a54
Participation in the expansion of TERA encourages growth and development of the idea of freedom from central administration, which was stated when Bitcoin was launched.
These are not just fantasies or dreams, there are authoritative representatives of science who consider blockchains to be the basis for the economy of future, which will have no boundaries. And with the help of active participants full decentralization will come much faster. This development has no limits, since it is fueled by the independent striving, own free will and potential that is inherent in each of us.

Monero is my favorite thing as of now. I mean like ever in the whole world. Its potential to basically free the world (of government tyranny, censorship, famine, central bankers, etc) is by far the most promising of any crypto out there, and probably more promising than literally any other thing or movement in the entire history of the world (besides OneCoin or Darth Vader). I am by no means a Dash pump and dumper where I just wanna see the price moon immediately (not that I'm opposed to that, obviously), or a Zcash fool where I have no idea what cryptocurrency is about (Zcash is a cult, imo), I'm a Moner, or whatever Monero people are called.
I just want it to be used! Which means, first and foremost, people have to be aware of its existence. What I've been doing, and I don't recommend this, unless you have a mountain of monero and an opinion of it as high as I do, is tell people to download the monero wallet, in exchange for me sending them a monero. I think this is much more effective than telling them "CryptoNight is much more ASIC resistant than SHA256!" or "ed25519 is more secure than secp256k1!" or whatever. It allows them to feel good when monero gets more expensive, maybe sad when it gets cheaper, but that emotional interaction with monero isn't something that's just forgotten, like those weird words they've never heard before are. First, they are given something they understand (an asset that might gain or lose value), and later they are waaay more likely to "fall down the rabbit hole" than some guy who doesn't own monero. (thus increasing user base and therefore security, privacy, and fungibility, and hopefully they'll not be able to contain their excitement, like me and have to tell yet more people) It's getting to be prohibitively expensive to do this, and I find that a lot of people simply will not accept less than an entire monero for that deal, idk why. Maybe cuz the current paradigm of nothing before the decimal signifies "change", i.e. worthless, or not worth downloading an "annoying blocktrain thing" (real quote). This is vexing. I know I'm not gonna go to my grandma and explain everything and have her be like "dam thats sweet im buying monero".
For people my age, (I'm 20) I want to be able to convey what it's all about, concisely and in a way that excites people more than something that's out of the scope of the concepts they understand. I'm sure some of you more enthusiastic Moners (or monerites?) have "converted" some crypto-foreigners. What's the best way to actively do this? Is there like a video I can sic on em or something? Every fluffyponyza presentation I've ever seen would go like 32.4 miles above the average person's head. They won't read getmonero, or do work to figure out what this obscure and seemingly boring thing is. Some people, especially now, won't be convinced that monero is worth their time, but a lot are open to it. How to effectively reach as many as possible is what I'm after. Would it be legal to have a FFS for a video or a small PR type deal about monero? Not that its gonna instantly make it the world reserve currency, but it could help attract devs or something, idk. Do you guys think something like that would be worth it?
I personally feel that it is important for monero to gain positive exposure, probably more than most people on here. If monero is this thing that people only hear about when they read a news report on a drug bust or ransomware attack, we'll have to go through the same phase bitcoin went through where the establishment along with Joe the Plumber wants it made illegal, or subject to more stringent KYC or AML regulations, cuz "only criminals use it". It is possible that some other crypto takes monero market share because of this. When bitcoin was at that stage, there was bitcoin. That was the crypto space. Now there are tempting scamcoins around every corner and I'd hate to see monero fall by the wayside, even temporarily, in lieu of some ridiculous thing like Zcash, which imo misses the whole point of cryptocurrency, or some sockpuppetty corporatecoin like eth. Privacy IS for everyone and I think it might be possible to skip this phase entirely, given the right information is widely distributed.
tl;dr How can I make the fundamental concepts behind Monero accessible and attractive to the average computer-using person, or potential devs who might otherwise be swayed to working on another alt or Bitcoin instead? ps Sorry for the long post I'm a piss poor writer and can't be concise
Edit: for formatting so its not a brick of words

EthereumCash Project
What is EthereumCash ?
EthereumCash is an experimental new digital currency that enables anonymous, instant payments to anyone, anywhere in the world. EthereumCash uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out collectively by the network. EthereumCash is a PoS-based cryptocurrency, and depend upon libsecp256k1 by sipa, the sources for which can be found here: https://github.com/bitcoin/secp256k1
EthereumCash is a project which was created in January 2017, launched by a group of Masters graduated in Technology Institutes of Hardware, Web Programming and CryptoCurrency. Currently, the project has 60 Antminer L3 + devices. EthereumCash was released to fund the development of the project, and using funds was a way to purchase new Antminer devices. The special issue is that we will pay EthereumCash holders 50% of the profits from the mining of us every 45 days since EthereumCash is listed on the exchange. On the other hand, our project is also interested in partners and is ready to collaborate by buying 30% EthereumCash and allowing us to use their existing Antminer devices with low fee. Our mining plan at the beginning of the project was to mine the coins to be issued or newly listed, with low difficult and then we waited and sold out at high prices beyond expectations. Besides, when we find the coin that we see has the potential for growth or high price expectations we will also bring all our equipment to mine those coin. We are young with a dynamic creativity, willing to devote as much to the success and development of the company.
