MoneyGram Got Another $11M From Ripple to Use Its Cross-Border Payments Tech MoneyGram Got Another $11M From Ripple to Use Its Cross-Border Payments Tech

Payments firm Ripple has given MoneyGram, a remittance firm, over $11 million dollars in the past half year, according to regulatory filings with the Securities and Exchange Commission (SEC).

The funds are broken up between two quarters, $2.4 million in Q3 and an additional $8.9 million in Q4, for a total of $11.3 million.

The Q4 "financial benefit" as MoneyGram calls the sum, was not included in its Q4 revenue, reported as $323.7 million.

Previously, MoneyGram has disclosed that it utilizes various Ripple products, including its On-Demand Liquidity product, which runs on XRP.

The firm behind XRP owns over 10 percent of MoneyGram common stock, acquired through investments adding up to $50 m…

IOTA Being Shut Off Is the Latest Chapter in an Absurdist History
IOTA Being Shut Off Is the Latest Chapter in an Absurdist History IOTA Being Shut Off Is the Latest Chapter in an Absurdist History

We’d seen press releases about an “official partnership” between the Germany-based IOTA Foundation and Microsoft, which the incumbent tech company later denied, as well as various universities.

Wall described this as the founding team, which launched the IOTA token in 2015, being “very effective at pushing out news about ‘partnerships.’”Among technologists, the IOTA Foundation became known for scandalous emails in 2018 between IOTA Foundation co-founder David Sønstebø and Neha Narula of MIT's Digital Currency Initiative.

The website and social media accounts for the token project are still up, but her personal social media accounts haven’t been active since the fall of 2019.

Bank of Canada Won’t Issue Its Own Crypto Unless Libra Succeeds: Deputy Governor
Bank of Canada Won’t Issue Its Own Crypto Unless Libra Succeeds: Deputy Governor Bank of Canada Won’t Issue Its Own Crypto Unless Libra Succeeds: Deputy Governor

The Bank of Canada has no plans to issue its own digital currency – at least, not at the moment.

The central bank does not see a real need to issue its own cryptocurrency unless a competitor to cash takes off, said Deputy Governor Timothy Lane.

His speech, titled "Money and Payments in the Digital Age," addressed how the central bank is approaching the idea of central bank digital currencies; in his view, cash works.

To be sure, Bank of Canada was one of the most active students of the CBDC concept, and it ran a pilot project on R3's distributed ledger tech solution Corda.

But it is a good example of a transformative technology that affects how the bank needs to respond to the future of mon…

We're concerned about coronavirus, but why?

Or are we just Chicken Little prophets of doom?

The spread of Coronavirus has dominated the news cycle across industries, but the discussion has been particularly fierce in both the finance and tech worlds, with crypto right in the lead.

For a month or more, prominent crypto voices have been discussing the event in terms of skepticism of reported government cases, questions of market impact, and plans for personal preparation.

NLW surveyed more than 1500 people on Crypto Twitter to ask why crypto was so interested in the Coronavirus.

Revolut, the London-based bank that allows users to purchase cryptocurrencies on its app, has raised more than $500 million in a Series D funding round.

Revolut added bitcoin (BTC) to its platform in July 2017, soon after its $66 million Series B.

Ether (ETH) and litecoin (LTC) followed later that year, with bitcoin cash (BCH) and XRP (XRP) support coming in May 2018.

The U.S. Commerce Department’s Bureau of Economic Analysis (BEA) has proposed a rule change to a benchmark survey that would require all U.S. financial services companies to identify if they engaged in cross-border services related to cryptocurrency.

The survey will be posed to brokerages, private equity funds, custody services, financial advisories and the many others included in BEA’s sweeping definition of "financial services."

That question, however, will not gather individual transaction information, said BEA Services and Surveys Branch Chief Christopher Stein.

Securities Law Helped Build Modern Capitalism. Crypto Should Embrace It Securities Law Helped Build Modern Capitalism. Crypto Should Embrace It

Securities are one of the most crucial components to the operation of our global economy.

For large companies, this is typically handled by trusted third parties like DTCC, which provides clearing and depository services.

Some in crypto think they can just build to violate these laws; it doesn’t work that way.

For example, Coinbase’s Crypto Ratings Council makes a case for why certain instruments are not securities, instead of doing the harder work to become licensed to deal in legal securities.

On the technical side, there many projects promising robust potential improvements in the way securities move.

A "short bitcoin" exchange-traded product (ETP), which inversely tracks the value of the top cryptocurrency by market cap, is now available to investors throughout Europe.

Swiss crypto product provider 21Shares, formerly known as Amun, said Tuesday its new "SBTC" tracker product would be available to both institutional and retail investors on Boerse Stuttgart, the second-largest stock exchange in Germany.

The new Boerse Stuttgart listing means retail investors are no longer "lumbered with fees and some pretty wide FX rates" from their brokerages, he said.

Polkadot is a network for connecting and launching blockchain applications, with its “parachain” technology acting as a bridge between different blockchains.

Until Polkadot launches, Chainlink’s pricing feeds will first service Polkadot’s experimental Kusama network.

However, the parachain between Chainlink’s decentralized pricing oracles and Kusama remains under construction, Polkadot said.

Derivatives exchange FTX is hosting a public sale for tokenized equity in the hopes it can attain a billion-dollar valuation.

The Binance-backed platform, famed for creating the Shitcoin Index of low-market coins, announced Tuesday its FTX_Equity token sale would welcome investors willing to allocate a minimum $250,000 each.

Each FTX_Equity token, valued at $2 each, represents an ownership stake in the FTX Trading Ltd., the holding company that owns the derivatives exchange.

It isn't clear what the exchange rate is between normal and tokenized FTX equity.

New Zealand Plans to Drop ‘Unfavorable’ Sales Tax Treatment of Cryptocurrencies
New Zealand Plans to Drop ‘Unfavorable’ Sales Tax Treatment of Cryptocurrencies New Zealand Plans to Drop ‘Unfavorable’ Sales Tax Treatment of Cryptocurrencies

New Zealand's tax authority is considering changes to its treatment of cryptocurrencies that would drop the current and controversial application of goods and services tax (GST).

Calling the situation "unfavorable," the New Zealand Inland Revenue Department (IRD) has now suggested doing away with the GST liability for cryptocurrencies in many cases, but keeping the treatment for income tax.

An issue being considered by the IRD is whether different types of token should have different tax treatments depending on how they are used.

"An advantage of this approach is that it should provide a neutral tax treatment for those crypto-assets which are close substitutes for existing financial product…

It's expected to serve the companies from Switzerland and the U.S., as Nornickel CEO Vladimir Potanin told Bloomberg Tuesday morning.

Ethereum’s cofounder Vitalik Buterin broke his silence on ProgPow on Monday, and criticized developers for how they handled the controversial upgrade proposal.

ProgPow would change Ethereum’s hashing algorithm, minimizing the advantage of so-called ASICs—chips optimized for faster mining—by effectively tilting the balance in favour of GPU miners.

That ProgPow was suddenly on the table again came as a surprise to many in the Ethereum community, including Buterin.

В ответ на сообщения СМИ о том, что Binance является «мальтийской криптовалютной биржей», регулятор заявил, что Binance не получала разрешение от MFSA на осуществление криптовалютной деятельности, поэтому биржа не подлежит регуляторному контролю со стороны этого органа.

У Binance нет главного офиса на Мальте, поэтому биржа не управляется из этого государства.

У Binance есть несколько регулируемых организаций по всему миру, которые управляются нашими партнерами или напрямую Binance.

Возможно, именно из-за этого биржу стали называть мальтийской, даже несм…

Проект Libra социальной сети Facebook не планирует использовать существующие языки для разработки смарт-контрактов.

«Move – это новый язык программирования смарт-контрактов, который войдет в основу проекта Libra.

Проект Libra предоставит единую платформу для переводов, которой смогут воспользоваться люди по всему миру.

Интересно, что, по словам Маурера, при создании Libra разработчики ориентировались на уже существующие децентрализованные проекты – Биткойн и Эфириум.

«Мы строим свой проект для финансового применения, для создания финансовой экосистемы для людей, которые не имели доступа к банковской системе.

Украинская криптовалютная биржа Kuna выпустила стейблкойн UAX, привязанный к украинской гривне в соотношении 1:1.

Новый стейблкойн создан на базе блокчейна Эфириума, поэтому UAX будет поддерживать основные стандарты ERC-20 и ERC-865.

Для привязки к украинской государственной валюте Kuna планирует внедрить метод аудита Proof-of-Reserve (доказательство резерва), который используется многими крупными криптовалютными биржами, в том числе биржей Kraken.

Стейблкойн будет публично представлен учредителем биржи Kuna Михаилом Чобаняном на конференции BlockchainUa 2020, которая состоится в марте.

По словам Чобаняна, Kuna станет первой биржей, которая выпустит стейблкойн, привязанный к гривне.

Один из законодателей штата Нью-Джерси представил законопроект, предполагающий получение лицензии криптовалютными компаниями.

Также компании, работающие в Нью-Джерси, должны опубликовать свои внутренние документы, включа…

You’ll probably get lost from time to time, but if I'm doing my job, you’ll still get the gist of it.

Now I'm a partner at a crypto venture capital firm called Dragonfly Capital—meaning in my day job I read a lot of white papers, evaluate technical crypto projects, and decide which ones to invest in.

Those are just APIs, specifications, and libraries—so long as you understand the core ideas behind how they work, you'll be able to figure out the details on your own.

Each lesson will have self-serve assignments tied to the course, both coding assignments and multiple choice questions to test your comprehension.

The term project will be to create your own fully-fledged cryptocurrency.

A Cambrian Explosion of Crypto Proofs
A Cambrian Explosion of Crypto Proofs A Cambrian Explosion of Crypto Proofs

By analogy, we are currently experiencing a Cambrian Explosion in the field of cryptographic proofs of computational integrity (CI), a subset of which include zero knowledge proofs.

The purpose of this post is to identify the common denominators of all CI systems implemented in code and discuss a few differentiating factors.

Takeaway: symmetric CI systems can arithmetize over any field, leading to greater efficiency.

¹ The term ZKP is often misused to refer to all CI systems, even ones that are not, formally, ZKPs.

To avoid this confusion we use the loosely defined terms of “crypto proofs” and “computational integrity (CI) proofs”.

What will happen to cryptocurrency in the 2020s?
What will happen to cryptocurrency in the 2020s? What will happen to cryptocurrency in the 2020s?

In addition to scalability, I think we’ll also see privacy integrated into one of the dominant chains in the 2020s.

These crypto startups will have the challenge that all startups have: making something people want.

In the 2020’s, I think we will see cryptocurrency adoption in emerging markets scale to hundreds of millions of users, with at least one country “tipping” so that the majority of transactions in their economy happen in cryptocurrency.

During the 2020’s I think we’ll see the cryptocurrency market structure evolve to more closely resemble the traditional financial world, with these functions being separated out from a legal and regulatory point of view.

Bitcoin becomes the Flag of Technology
Bitcoin becomes the Flag of Technology Bitcoin becomes the Flag of Technology

As such, it will become widely recognized as the flag of technology over the course of the 2020s.

To understand this claim, we need to define what "technology" is, what a "flag" would mean in this context, and why Bitcoin would be chosen as that flag.

Bitcoin: an ideological flag and a Schelling pointRecall that not every flag represents a geographical entity.

Bitcoin also becomes a flag in another sense: a rallying point, a Schelling point for an entrepreneurial community.

Bitcoin encodes the values of TechnologyBut when the global tech community rallies around the flag of Bitcoin, what exactly is it getting behind?

What are the Key Properties of Bitcoin?
What are the Key Properties of Bitcoin? What are the Key Properties of Bitcoin?

Bitcoin is a system that automates the continual discovery of consensus amongst its participants.

Bitcoin seeks to address the root problem with conventional currency: all the trust that’s required to make it work .

There are, unfortunately, many known threats to the privacy of Bitcoin users and as a result, Bitcoin in its current state is far from perfectly fungible.

ConvergenceAny two Bitcoin clients, if they connect to a single honest peer, should eventually converge on the same chain tip.

As an example, Bitcoin ABC broke this principle by instituting a 10 block maximum chain reorganization rule.

Credible Neutrality As A Guiding Principle
Credible Neutrality As A Guiding Principle Credible Neutrality As A Guiding Principle

And that principle is this: when building mechanisms that decide high-stakes outcomes, it’s very important for those mechanisms to be credibly neutral.

Note that it is not just neutrality that is required here, it is credible neutrality.

Hence, the principle of credible neutrality, must also be augmented with another idea, the principle of efficacy.

Sometimes, this even means that if a credibly neutral mechanism to solve some problem has not yet been found, an imperfectly neutral mechanism should be adopted in the short term.

Credibly neutral mechanisms for solving many kinds of problems do exist in theory, and need to be developed and improved in practice.

States cannot be trusted with absolute power, and power over money is their best weapon in controlling people and spreading misery.

And when we get going about sound money, and the idea that fiat money = misery, therefore cryptocurrencies = freedom and happiness, it just sounds insane to them.

We are not interested in it.”It took smart people years to understand the power of the Internet, and it will take smart people years to understand the power of crypto currencies.

Or any of thousands of other experiments being conducted by smart people trying to do their own thing.

In this beginner’s guide to decentralized finance (“DeFi”) we review the following:Stablecoins.

Decentralized lending.

And these smart contract lego pieces can even create completely new concepts that haven’t been explored in the traditional world.

Another potential issue is that the interest rate volatility on many DeFi platforms could make it impractical for someone to participate.

With that said, these hedging methods themselves are in their infancy, and add smart contract risk of their own.

Meanwhile, from the perspective of crypto outsiders (including many people, banks, and governments), anything concerning crypto is scary—no one controls it!—and decidedly not pragmatic.

First, we offered secure and simple crypto storage, which amounted to centrally storing decentralized currency.

Second, we allowed people to purchase Bitcoin and Ether, which meant buying crypto with fiat currency.

And you definitely created more crypto users overall by providing storage capabilities than by offloading that to the user.

Indeed, some advanced crypto users were quick to point out that self-custody is “simple” to do.

Zcash, the HTTPS of Blockchains
Zcash, the HTTPS of Blockchains Zcash, the HTTPS of Blockchains

The solution then was an encrypted web-browsing protocol for the public internet called HTTPS.

We've developed a conceptually similar solution today for encrypted transactions on a public blockchain, called Zcash.

In a fully shielded Zcash transaction, the timestamp is public, but no information about sender, receiver, or amount is public.

Like HTTPS, fully shielded Zcash transactions prevent eavesdropping and protect financial privacy.

Just as HTTPS became standard on the public internet to protect credit card transactions, we believe strong encryption will in time become standard on public blockchains to protect cryptocurrency transactions.

Public-Key Cryptography
Public-Key Cryptography Public-Key Cryptography

EncryptionTo understand public-key cryptography, we have to start with what we mean by encryption.

Public keys as identityIn public-key cryptography, a crude but useful analogy is to think of your public key like a username.

This is precisely what makes public-key cryptography feasible as a form of identity.

If those assumptions turn out to be false, it would imply that all of our public-key cryptography were fundamentally broken.

Most of your interactions with public-key cryptography you'll be outsourcing to libraries, so there's no need to get deep in the weeds quite yet.

Okay, so how difficult is it to generate a hashcash PoW with a difficulty level of \(N\) bits?

The first is limiting each hashcash token to a specific email address, so they're not reusable for different recipients.

You can see some Hashcash tokens Adam Back generated on the Hashcash website, such as this one:from hashlib import sha1 sha1(b"0:030626:adam@cypherspace.org:6470e06d773e05a8").hexdigest() # '00000000c70db7389f241b8f441fcf068aead3f0'This hashcash digest has 8 leading zeros in hex, equivalent to 32 leading zeros in binary.

To mitigate this, Hashcash requires the email server to remember any Hashcash tokens received in the last day.

Merkle trees were invented by Ralph Merkle, one of the forefathers of modern cryptography.

Merkle trees are used widely in many applications, including Git, BitTorrent, ZFS, the Certificate Transparency framework, and of course, pretty much every cryptocurrency.

Merkle trees are also known as hash trees, because they hash data upwards in a tree.

Merkle trees in BitcoinInclusion proofs are a powerful primitive enabled by Merkle trees.

There are many more innovations on Merkle trees that are worth exploring, including proofs of non-inclusion, online updates, and n-ary Merkle trees.

Hash Functions
Hash Functions Hash Functions

But if you need stronger security (like Bitcoin does), you should use a more robust subset of hash functions known as cryptographic hash functions.

You would not use a cryptographic hash function in a hash map, since cryptographic hash functions pay for their security with worse performance.

Cryptographic hash functionsCryptographic hash functions come with three additional requirements over normal hash functions.

Thus, we know that all hash functions must have collisions—after all, all hash functions have finite output sizes, yet infinitely many possible inputs.

This is why robust cryptographic hash functions are harder to build than normal hash functions.

We don't know who Satoshi Nakamoto was.

Satoshi Nakamoto began coding the first implementation of Bitcoin in C++ in May of 2007.

But mostly, early on, Satoshi Nakamoto himself was the only person running the software and mining coins.

Having slowly distanced himself from the day-to-day of Bitcoin, Satoshi eventually faded away from the project permanently.

There has never been any proof that any individual is Satoshi Nakamoto.

To make the process faster and more convenient, Charlie created BitInstant in 2012. BitInstant quickly grew and by 2013 became responsible for processing a third of all Bitcoin transactions. This was with the help of Roger Ver and the Winklevoss twins, who were his seed investors, and Erik Voorhees, who led their marketing efforts. The success of BitInstant was short-lived.

We also talk about whether DeFi should institute circuit breakers, when those would make sense, and whether these attacks could happen to anybody or whether bZx isn’t up to the standards needed in this community.

We also cover how bZx should handle the under-collateralized loans left on their platform, whether Chainlink will be a sufficient solution to prevent these attacks in the future, and whether DeFi insurance should cover these kinds of attacks.

The lack of a reliable human identity protocol is the missing element preventing democracy from happening on the internet today.

The consensus was that any relevant attempt to formalize human identity will inevitably be attacked by powerful actors, while lacking formal human identity risks leaving the whole crypto-economy under tyrannical …

Alex Gladstein, chief strategy officer at the Human Rights Foundation, reads his essay, A World Without Bitcoin.

In the Bitcoin world, however, it’s much more difficult for bankers to steal your money and for governments to devalue your savings.

In most major urban areas on earth, there is some mixture of Bitcoin ATMs, peer-to-peer marketplaces, Bitcoin brokers, and brick-and-mortar exchange points.

Fourth, consider the growing number of people who are falling under intense daily financial surveillance.

In the progression of the global banking elite first ignoring Bitcoin, then laughing at Bitcoin, then fighting Bitcoin, and then giving up, we are nearing the end of the laughing phase.

You know, that’s really where we saw the need, and Binance has done a wonderful job of facilitating global economies to help this out.

You’ve also got, you know, that’s where you’re going to be leaving market orders.

And so, that’s really one of the components that was early on that we factored in.

So, you know, start your day off with really, really low trading fees.

That’s a huge progression from where we’ve been, and I think that’s something that is smart for the world to take awareness of.

They explain what they think will happen in the smart contract platform race, why Ethereum is so far in the lead and whether anything will become an Ethereum killer.

All that stuff I think has been really, really valuable in not just evaluating crypto projects but in becoming a good investor.

We fundamentally believe that there’s going to be…Bitcoin isn’t the only thing that’s going to succeed in the space.

Haseeb Qureshi:So, I think Bitcoin, it’s been pretty hard…as investors when we look at Bitcoin there are two questions you need to ask yourself.

Is that in the category of DAOs, or do you think Moloch Dow, or do you think things like Nexus Mutual?

Unchained Year in Review: The Best of 2019
Unchained Year in Review: The Best of 2019 Unchained Year in Review: The Best of 2019

In this Best of 2019 episode, I selected the clips that seemed most representative of what crypto was about this year, which I call, The Year Things Got Geopolitical.

My only regret is that none of the clips about DAOs lent themselves well to this episode.

However, years from now, after we’ve got global stablecoins pinging around the world at a high transactions-per-second rate, the crypto community has made peace with U.S. regulators, and more of our lives seems to take place in the borderless digital world, perhaps we’ll find it ironic that DAOs were burbling up right around the same time.

Thank you to our sponsors!

For Your Normie Friends: Answers to the Most Basic Crypto Questions
For Your Normie Friends: Answers to the Most Basic Crypto Questions For Your Normie Friends: Answers to the Most Basic Crypto Questions

I cover basic explanations of Bitcoin, blockchain and Ethereum, plus we go into questions around mining and electricity usage, and why anyone would use cryptocurrency.

That, in a nutshell, is how the Bitcoin software works, but instead of people in a village shouting, it uses computers running the Bitcoin software that are spread across the globe.

Miners are any computers that run the Bitcoin software and add transactions to the ledger.

For about the first four years the Bitcoin software ran, it dispensed 50 bitcoins every 10 minutes.

Because bitcoin transactions are shared on a public ledger, it is theoretically possible to trace bitcoin transactions.

About this EpisodeIn this week’s episode, we take the podcast in a slightly different direction and dive into Isogenies - a topic at the cutting edge of cryptography.

We look at how they are related to VDFs and randomness generation.

Our guest, Luca de Feo, one of the co-inventor of SIDH, helps us get an understanding for what Isogenies - or morphisms of algebraic groups - really are.

CVE-2017-18350 Disclosure
CVE-2017-18350 Disclosure CVE-2017-18350 Disclosure

Disclosure of the details of CVE-2017-18350, a fix for which was released on November 6th, 2017 in Bitcoin Core version 0.15.1.

The vulnerability was introduced in 60a87bce873 (SOCKS5 support) and first released in Bitcoin Core v0.7.0rc1 in 2012 Aug 27.

To be vulnerable, the node must be configured to use such a malicious proxy in the first place.

Upon a connection request from the node, the malicious proxy would respond with an acknowledgement of a different target domain name than the one requested.

To fix this vulnerability, the dummy buffer was changed to an explicitly unsigned data type, avoiding the conversion to/from a negative number.

CVE-2018-17144 Full Disclosure
CVE-2018-17144 Full Disclosure CVE-2018-17144 Full Disclosure

Full disclosureCVE-2018-17144, a fix for which was released on September 18th in Bitcoin Core versions 0.16.3 and 0.17.0rc4, includes both a Denial of Service component and a critical inflation vulnerability.

Thus, in Bitcoin Core 0.14.X, any attempts to double-spend a transaction output within a single transaction inside of a block will result in an assertion failure and a crash, as was originally reported.

In Bitcoin Core 0.15, as a part of a larger redesign to simplify unspent transaction output tracking and correct a resource exhaustion attack the assertion was changed subtly.

Instead of asserting that the output being marked spent was previously unspent, it only asserts that it exists.…

Bitcoin Core 0.16.3 Released
Bitcoin Core 0.16.3 Released Bitcoin Core 0.16.3 Released

Bitcoin Core version 0.16.3 is now available for download with a fix for a denial-of-service vulnerability introduced in Bitcoin Core 0.14.0 and affecting all subsequent versions though to 0.16.2.

We highly recommend users of all affected versions immediately upgrade to 0.16.3.

Security issue CVE-2018-17144: it was discovered that older versions of Bitcoin Core will crash if they try to process a block containing a transaction that attempts to spend the same input twice.

This release eliminates the crash, allowing the software to quietly reject such invalid blocks.

Bitcoin Core 0.16.2 Released
Bitcoin Core 0.16.2 Released Bitcoin Core 0.16.2 Released

Bitcoin Core version 0.16.2 is now available for download.

The attack was considered unlikely given that much cheaper attacks of roughly equal effectiveness are well known.

Similarly, the getblock RPC also now returns extra information that can be used to defeat this attack even if the requested block has been pruned.

As before, you can call this RPC when you no longer want your wallet to re-broadcast an old unconfirmed transaction.

If have any questions, please stop by our IRC chatroom and we’ll do our best to help you.

Bitcoin Core version 0.16.1 is now available for download.

Fixing a bug that could’ve potentially caused miners to lose revenue if they produced two blocks in very rapid succession.

The presence of this opcode makes it difficult for nodes to estimate how much computational work will be required to validate a legacy signature script.

Because of that, it blocks the deployment of solutions to prevent attackers from creating blocks that require a long time to validate.

Notable changesNetwork fork safety enhancementsA number of changes to the way Bitcoin Core deals with peer connections and invalid blocks have been made, as a safety precaution against blockchain forks and misbehaving peers.

This ensures that everything that descends from an invalid block is marked as such.

Miner block size limiting deprecatedThough blockmaxweight has been preferred for limiting the size of blocks returned by getblocktemplate since 0.13.0, blockmaxsize remained as an option for those who wished to limit their block size directly.

Further, the blockmaxsize option is now used only to calculate an implied blockmaxw…

There have been attempts to mislead people into believing that the btc1 project, the implementation of the Segwit2x proposal, is a necessary update to existing software—it is not.

Lightning + Liquid = ♥ Lightning + Liquid = ♥

Now users can take advantage of early Lightning support for instant Liquid Bitcoin (L-BTC) micropayments; with support for other Liquid assets coming soon.

The addition of Lightning support serves as an example of how easy it is to port an existing Bitcoin application of any complexity to Liquid, and Lightning is relatively complex, trust me on that!

This allows any user to build gateways into and out of the Liquid network considerably speeding up onboarding users into the Liquid network, as well as providing users with a seamless experience to move their funds off of the Liquid network, without going through lengthy peg-in and peg-out processes.

In lnd v0.9-beta , we’re making a significant step in this direction with the ability to receive “multi-path payments” (MPPs) (the non-spontaneous variant).

“Single-shot” MPP payments are essentially an updated, safer form of “normal,” unsplit Lightning payments.

Staying Safe from the Recent Lightning Vulnerability

We have created tools one can use to check if your lnd node was targeted.

The exploit was fully patched in lnd version v0.7.1 (released July 30th 2019) and partially patched in version v0.7.0 (released July 2nd 2019).

Of the two checks, failure to check the scriptpubkey (#1) is more disastrous, since an attacker can costlessly open thousands of invalid channels per block.

If you’re running lnd version v0.7.1-beta and above, then you’re safe.

Channel LimitsThe Lightning Network specification currently requires a hard funding limit of 16.7M satoshis, and a payment limit of 4.2M satoshis.

Loop Out In-depth

You are effectively looping the payment back to yourself, hence the name Lightning Loop.

The user sends a payment tied to this hash to the Lightning Loop server.

To prevent this the server requires a second Lightning payment called the prepayment to be made along with the swap payment.

From that point onwards, the preimage is to be considered public knowledge and the user should expect their Lightning payment to be settled at any time.

With the received on-chain funds another channel can be opened and this channel can be Looped out too.

Safety is the idea that decisions cannot be unmade whereas liveness captures the notion that new things can be decided.

When these assumption don’t hold, FLP Impossibility is the proof that at least one of: safety, liveness, or full asynchrony must be compromised.

In particular, eth2 uses a variation of GHOST which has been adapted to a PoS context called Latest Message Driven GHOST (LMD-GHOST).

GHOST’s favourable liveness properties allow new blocks to quickly and efficiently be added to the chain, while FFG follows behind to provide safety by finalising epochs.

By construction, the last finalised block is always a part of the chain which means GHOST doesn’t need to consider earlier blocks.

Binary Trie size savingsTransitioning to a binary trie structure (instead of the current hexary trie structure) should in theory reduce the size of witnesses by something like 3.75x, but in practice that reduction might only be about half, depending on how you look at it..

Hashes within the trie are reduced by 3x, but code is not improved with a binary trie, since it always needs to be included in the witness.

So switching to a binary trie format will bring witness sizes to ~300-1400kB, down from ~800-3,400kB in the hexary trie.

Validated, staking on eth2: #1 - Incentives Validated, staking on eth2: #1 - Incentives

More specifically, we look at the incentives effecting eth2 and how they are realised in the form of rewards, penalties, and slashings.

Slashing a validator is to destroy (a portion of) the validator’s stake if they act in a provably destructive manner.

To minimise the pain of such errors, the amount of stake destroyed is proportional to the number of other validators slashed around the same time.

Proposer rewards ⬜️⛓⬛️⛓⬜️Validators are randomly assigned the duty of producing a block; the chosen validator is called the proposer.

In the fixed reward model, validators are paid a fixed amount for doing their jobs, and the inflation rate then depends on how many validators sign up.

It’s a way of packing the totality of Ethereum state into one unified structure.

We can ballpark the current state of Ethereum at around 400 million nodes in the state trie.

Staying in sync with the Ethereum blockchain is, effectively, constantly building a new version of the state trie over and over again.

Or, it might involve working out an alternative implementation of the state trie more amenable to witness generation.

Review of Gitcoin Quadratic Funding Round 3 Review of Gitcoin Quadratic Funding Round 3

Special thanks to the Gitcoin team and especially Frank Chen for working with me through these numbersThe next round of Gitcoin Grants quadratic funding has just finished, and we the numbers for how much each project has received were just released.

But what matters more here are not the raw donations, but rather the subsidies that the quadratic funding mechanism applied.

Pairwise-bounded quadratic funding vs traditional quadratic fundingRound 3 differs from previous rounds in that it uses a new flavor of quadratic funding, which limits the subsidy per pair of participants.

ConclusionsOn the whole, this was by far the largest and the most data-rich Gitcoin funding round to date.

Understanding PLONK
Understanding PLONK Understanding PLONK

How PLONK worksLet us start with an explanation of how PLONK works, in a somewhat abstracted format that focuses on polynomial equations without immediately explaining how those equations are verified.

We will need to create a structured system of equations, which will ultimately reduce to a very small number of polynomial equations, to represent both.

To make the problem actually challenging (and actually represent the problem encoded in the original circuit), we need to add an equation that verifies "copy constraints": constraints such as \(a(5) = c(7)\), \(c(10) = c(12)\), etc.

The only remaining polynomial in the above equations is \(Z(x) = (x - 1) \cdot (x - \omega) \cdot ... \cdot (x …

The Dawn of Hybrid Layer 2 Protocols
The Dawn of Hybrid Layer 2 Protocols The Dawn of Hybrid Layer 2 Protocols

A more recent proposal, ZK Rollup, does the same thing without challenge periods, by using ZK-SNARKs to verify blocks' validity.

This technique is thus not a jaw-droppingly huge scalability gain, because the on-chain data overhead eventually presents a bottleneck, but it is nevertheless a very significant one.

With BLS aggregate signatures a similar throughput can be achieved in shadow chains (more recently called "optimistic rollup" to highlight its similarities to ZK Rollup).

So what is the benefit of data on-chain techniques such as ZK/optimistic rollup versus data off-chain techniques such as Plasma?

Then there is a large middle ground between data-on-chain layer 2 and data-off-chain la…

Sidechains vs Plasma vs Sharding
Sidechains vs Plasma vs Sharding

Plasma chains are sidechains that have a non-custodial property: if there is any error in the Plasma chain, then the error can be detected, and users can safely exit the Plasma chain and prevent the attacker from doing any lasting damage.

That is, a child chain block that specifies an invalid main chain block as a dependency is by definition invalid, and more importantly a main chain block that includes an invalid child chain block is by definition invalid.

However, the consequences of a single Plasma chain failing are localized to within that Plasma chain.

Second, there are better strategies to handling data availability than fishermen: data availability proofs.

A Plasma chain can always b…

Discussion about taproot versus alternatives: a group of developers who prefers to remain anonymous (so we’ll call them Anon) wrote a criticism of taproot in comparison to alternative approaches for enabling MAST and schnorr signatures in Bitcoin.

Anon asks, “Is taproot actually more private than bare MAST and schnorr separately?

MAST could also be used for single-sig spends but it would require larger transactions and more fees than a pure single-sig construction, so single-sig users would probably not use MAST.

That would create a clear divide for chain analysis between spends that use MAST and spends that don’t.

Safety concerns related to precomputed public keys used with schnorr signatures: libsecp256k1 PR #558 proposes adding BIP340-compatible schnorr signature creation and verification to the libsecp256k1 library used by Bitcoin Core and several other Bitcoin programs.

Since BIP340 requires signatures to commit to the public key that will be used to validate the signature, the current proposed signature function uses the private key to derive the necessary public key.

Gregory Maxwell noted that programs generating signatures will usually already know the appropriate public key, so the function can save CPU time by accepting the public key as a parameter.

This would require special support from both the spender and the peer who’s able to route to the unannounced channel, but other nodes along the routing path would not need to change their implementation.

The protocol prevents even the spender from learning the receiver’s Bitcoin address (within the limits of the anonymity set).

Developer ZmnSCPxj notes that the technique is similar to tumblebit , which provides a trustless chaumian payment service.

The oracle doesn’t need to know the terms of the contract (or even that there is a contract).

The contract can look like either the onchain part of an LN transaction or it can be executed within an LN channel.

Anyone interested in DLCs may also wish to review the scriptless scripts repository that documents other clever applications of digital signature schemes to contract protocols.

Discussion of soft fork activation mechanisms: Matt Corallo started a discussion on the Bitcoin-Dev mailing list about what attributes are desirable in a soft fork activation method and submitted a proposal for a mechanism that contains those attributes.

Alternatively, a BIP8 flag-day soft fork fulfills the fifth criteria but encounters challenges fulfilling the other four criteria.

Corallo also worries that using BIP8 from the start of a soft fork deployment gives the impression that the developers of node software get to decide the rules of the system.

Watchtowers for eltoo payment channels: eltoo is a proposed alternative payment channel layer for LN that doesn’t require participants be able to generate penalty transactions.

Conner Fromknecht started a thread asking what data watchtowers would need to store for eltoo and how that would affect the scalability of watchtowers or the privacy of their clients.

This is highly scalabale because it only requires a constant amount of storage per channel, and it’s secure because only the final settlement transaction can spend from the final update transaction.

The offline node can broadcast the settlement transaction whenever it next comes online, even if that is months or years later.

Ethereum 2.0 Phase 0If the Bitcoin network is at risk of stagnating, one could argue the Ethereum network risks being too aggressive about upgrades.

This is exemplified by the striking plans for Ethereum 2.0.

Link Ethereum 2.0 will launch in three phases, and after many previous timelines have been pushed back, Phase 0 is looking like it will finally roll out this year.

PolkadotSpeaking of Ethereum competitors, I suspect one of the reasons for a sense of urgency around Ethereum 2.0 is the impression that competitors could start playing catch up this year.

For any one of these projects, failure to ship would leave their respective network in a precarious position.

📰NewsThis week, the Zcash network — known for using a mind bending form of cryptography called zero knowledge proofs to enable privacy preserving transactions — successfully executed an upgrade hardfork.

The money from the rewards was also use to fund the Zcash Foundation— a separate non-profit entity tasked with supporting the Zcash community.

To start, the process has occurred largely on the Zcash community forums, where thirteen distinct proposals were made.

Finally, it lays out a striking plan to scale the Zcash blockchain horizontally by leveraging bleeding edge technique called Halo Proofs.

For one, Zuckerberg affirmed that Facebook would not launch Libra unless given the green light by regulators.

He also pushed the narrative that the U.S. would be "out innovated" by China if regulators killed his company's project.

Link On Friday, Xi Jinping, the leader of China, said his country must "seize the opportunity" in adopting blockchain.

They don't.Why, then, do both men insist that they're interested in pushing "blockchain technology" forward.

Simply put, they're looking to co-opt and exploit a movement that threatens to subvert their own power.

Since MCD launched 3 months ago, MakerDAO has generated 719k DAI in net fees (calculated by the sum of stability fees and penalty fees minus DSR costs).

This translates into a 3.9% annual net margin on average debt issued, which is well above the 0.5% average DSR spread that MakerDAO had in that same period.

This higher margin is explained by both lower DSR utilization and extra income from 95k in DAI penalty fees.

(Note: that the actual net fee margin is always higher than DSR spread if the DSR has sub-100% utilization.)

This can be explained by the low DSR spread and also low rates in general from the launch of MCD in order to incentivize CDP migration.

DAI locked in the DSR has been steadily increasing since the beginning of the migration period.

The most notable increases were in the third week of December when Compound implemented the DSR for its unutilized DAI and during the second week of December when the DSR rate increased from 2% to 4%.

The recent rate increase of the DSR from 4% to 6% continued the linear pace of DAI being locked in DSR until last week when DSR utilization fell to previous levels seen before the rate increase.
