Vitalik proposes solution to link certain layer-two scaling projects

Republished by Plato

In an ongoing effort to battle escalating transaction fees while creating a unified ecosystem, Ethereum co-founder Vitalik Buterin has proposed a solution for a particular type of cross-rollup scaling.

The proposal outlines how two protocols using rollups can communicate with each other while maintaining interconnectivity and composability.

Rollups are layer-two solutions that are essentially smart contract networks that process and store transaction data off the main chain. However, there are a number of different rollup types, with each using unique smart contracts such as optimistic and zero-knowledge.

While a number of DeFi projects have deployed layer-two rollups, such as Loopring and Synthetix, the particulars of the various rollups mean projects are unable to communicate to one another directly on layer-two.

Buterin’s proposal assumes that one rollup can process simple transactions whereas the other has full smart contract support. There are already proposals for transfers between two smart contract enabled protocols using rollups.

To explain how the proposal works, Buterin provides the example of a hypothetical exchange intermediary he called ‘Ivan’ — where Ivan has an account ‘IVAN_A’ on rollup A that he fully controls, and also has some funds deposited in a smart contract ‘IVAN_B’ on rollup B.

The smart contract would be programmed to accept “memos” that include additional data from anyone sending to it in order to secure any future transactions. The transactions create a connecting layer that keeps deposits in all these isolated contracts, allowing rollup A to send to rollup B via this layer.

Buterin suggested that the behavior would work as follows;

“Alice sends a transaction to IVAN_A with N coins and a memo ALICE_B. Ivan sends a transaction sending TRADE_VALUE * (1 – fee) coins through IVAN_B to ALICE_B”

He added that the worst-case behavior would be if Ivan does not send coins to ALICE_B as he is expected to.

Addressing the “worst-case” scenario that could arise as a result of using the proposed situation, Buterin emphasized that Alice would still be able to wait until the transaction on rollup A confirms, find some alternate route to getting coins on rollup B to pay fees, and then simply claim the funds herself.

Responding to the proposal, Alon Muroch pointed out that it worked in a similar way to how banks clear transactions:

“That’s very interesting, similar to how banks clear transactions between themselves. Batching assets into separate “accounts” could have limitations, a solution could be just big pools on either ends and fees split pro-rata.”

Bitcoin Bull Mike Novogratz Predicts Existential Crisis Unless the US Creates a Digital Dollar

Republished by Plato

Published

Mike Novogratz, a veteran investor, and a huge Bitcoin supporter noted the U.S. is currently in a good economic position. Still, the nation can face a major competitive disadvantage unless it engineers a digital dollar soon.

The Importance Of An E-Dollar

Novogratz, chief executive of digital merchant bank Galaxy Digital GLXY, underlined the value that a digital dollar could bring to the US. In a Friday interview with MarketWatch, he stated:

”To me it is an existential crisis, we need a digital dollar.”

Furthermore, the investor expressed his view over the current COVID pandemic and the negative impact on the U.S. market and the world, in general. He referred to the trillions of dollars of monetary and fiscal spending done to help eliminate the worst of the economic aftershocks the disease caused:

”If our fiscal and monetary policy starts looking like it’s from a Banana Republic…you are going to run into some Minsky moment where confidence breaks down.”

With his statement, Mike Novogratz referenced Hyman Minsky, who exposed a view in the recent past that a period of distortions in the financial system eventually ends very badly.

The existence of a digital dollar sounds even more important after some stock-market investors have been warning about a surge in US inflation in the past weeks.

The Competition With China

During the interview, Novgorotz claimed that while in the U.S., the development of an e-dollar is still under question and researches, China has fired the first salvo on the digital currency front.

The biggest economy in Asia conveys great support to its digital yuan. According to some experts in the field, its new currency is a weapon that the country can use to compete with the U.S. and other developed economies.

As CryptoPotato recently reported, PayPal CEO Peter Thiel said that Bitcoin could be used as a Chinese financial weapon against the U.S.

In the meantime, Novogratz said that there is ”zero evidence of the Chinese government buying Bitcoin” much less weaponizing it, referring to the comments made by Peter Thiel:

”Sometimes he likes to say things that are provocative.”

Ripple becomes tidal wave, leads weekend pump and notches legal victories

Republished by Plato

Published

on

Amid a weekend pump carrying multiple cryptocurrencies higher, Ripple’s XRP looks to be leading the way with a push as high as 30% on the daily — carried on the back of a string of legal victories and rumors of relisting at some exchanges. 

Where Bitcoin and Ethereum are up merely 2.7% and 3.4% respectively on the day, XRP climbed to $1.36 before retreating to $1.32, where it sits at the time of publication. The digital currency is now up 111% on a 7 day basis, and a staggering 544% on the year. The recent push has also buoyed XRP back into the top 10 cryptocurrencies by marketcap, behind only BTC, ETH, and BNB at #4.

The rally flies in the face of a lawsuit from the Securities and Exchange Commission, which charges that XRP’s $1.3 billion ICO was an “unregistered securities offering.” The news led multiple exchanges to delist the currency, and XRP lost its place as the 3rd largest currency by marketcap, at time looking as if it would even fall out of the top ten. 

The bad news for XRP didn’t stop with the SEC, either. In March Ripple CEO Brad Garlinghouse announced that the company would be “winding down” its relationship with Moneygram — a once highly-touted partnership that investors often pointed to as proof of the digital currency being on a path towards becoming “the standard” for payments and settlement.

Despite the deluge of negative headlines, it appears all buyers needed was a small ray of hope to jump back in — and they’ve gotten exactly that. Ripple lawyers have notched two victories in their legal battle against the SEC, including winning access to internal SEC discussion history regarding cryptocurrencies, and a court denied the SEC the ability to disclose the financial records of two Ripple execs, including Garlinghouse.

Ripple executives themselves seem heartened by the news, with CTO David Schwartz saying the US isn’t “prepared” to regulate cryptocurrencies (a possible dig at the ongoing legal proceedings).

All in all, it’s just another week for one of the most controversial cryptocurrencies in the space.

Why this OlympusDAO’s product could be amongst DeFi most lucrative

Republished by Plato

Published

on

Taking the market by storm, OlympusDAO’s native OHM is up 95.8% this week alone and 31.1% in the past two weeks. At the time of writing, OHM is trading at $812,76 with 7.3% profits in the 24-hour chart.

With a market cap of just $68 million, OlympusDAO might have gone unnoticed by many investors. However, it has a mechanism called Bonds which promises to be one most important and lucrative in the DeFi sector.

According to research firm Messari, this protocol is attempting to create a stable currency backing every OHM with DAI and OHM-DAI. The objective is to maintain a “fundamental check on inflation” and a currency with an undiluted purchasing power.

Unlike Tether and other stablecoins, OHM is not pegged to any other asset. Its stability is achieved via the DAO (Decentralized Autonomous Organization) when it alters variables to obtain more profitability for stakers.

This is done via the sales contract connected to the protocol’s treasury and a liquidity pool (OMH-DAI) on decentralized exchange Sushiswap, as shown below. Messari explains:

When OHM trades above 1 DAI, the protocol mints and sells new OHM. When OHM trades below 1 DAI, the protocol buys back and burns OHM. In each case the protocol makes a profit. Olympus DAO distributes these profits 90% to OHM stakers pro rata and 10% to a DAO.

How OlympusDAO’s bonds operate

The Bonds are a treasury component to get liquidity with it users can trade Stake Liquidity Provider tokens to get OHM directly with the protocol, as an OlympusDAO developer explained.

Once the trade is completed there is a vesting schedule of 5 days. During this time, the user can redeem the tokens but has incentives to get them at a discount. The latter is determined by the number of bonds in the protocol, more bonds are equal to a lower discount.

Via this mechanism, as the developer said, OlympusDAO restrains its own growth, to have become “steadier”.

The liquidity from a bond is locked in the treasury and used to back new $OHM. That liquidity now belongs to the market and, by extension, the token holders. The more liquidity the protocol builds up, the more confident holders can feel.

The users are basically contributing to OlympusDAO by adding liquidity. In retribution, the user gets a reward in OHM at a much cheaper price during a specific period. That way, both the user and the protocol can benefit.

OlympusDAO offers LP a variety of strategies around OHM which they can leverage to obtain a bigger profit than on the spot market. The developer claims:

All of this serves to create a long-term, sustainable bootstrapping mechanism for the protocol, with participants as the main beneficiaries. A good system shouldn’t offer one opportunity to “make it”; it should offer them in perpetuity with diminishing returns. This is how you produce wealth; slowly, through compounding gains.

Ethereum is trading at $2096,58 with a 1.2% profit in the 24-hour chart, after dropping from its ATH at $2,198.
