Chainlink rolls out OCR system upgrade, reducing gas costs tenfold

Chainlink (LINK) has launched a major upgrade for its oracle network, dubbed Off-Chain Reporting, or OCR. The upgrade was announced on Wednesday, though the implementation has been live for some time already.

OCR changes how data across multiple sources is joined together by the oracle network. Previously, the process of aggregating different readings of the same desired input, for example a token’s price, was done on-chain. Chainlink nodes would submit their individual readings of the data, which would be verified by a smart contract on Ethereum and other blockchains. This approach, while guaranteeing reliability of the data, was inefficient in terms of gas costs, as each node would need to spend resources to publish the data.

The new architecture replaces on-chain aggregation with an off-chain consensus round. The aggregated data is then passed on to the blockchain, where a smart contract verifies that a quorum of nodes agreed on this version of the data.

Sergey Nazarov, founder of Chainlink, told Cointelegraph that the team has been working on the protocol since 2017. “We’ve started to put the best minds behind [it] over the last year and a half and have done substantial multiple audits on it,” he added.

The most immediate effect of the upgrade is reduced gas costs and load on the Ethereum network. According to the team, the upgrade will result in a tenfold increase in the amount of real-world data that could be available on the blockchain. As Nazarov explained, this increase is “partially related” to the gas limitations of the Ethereum blockchain:

“I think the nuance here is that we want to do this in a scalable way, basically, and we want to do it in a scalable way that works for Ethereum and various other chains. What this means is that, in times of congestion, the system should be able to continue to deliver these amounts of data because when you architect a system like this, you don’t architect for the best case.”

Chainlink nodes thus could have chosen to publish more data with the previous system, though the gas costs would have made that significantly difficult. “Our system needs to be able to function even in extreme situations, which so far it has been, better than all other oracles,” continued Nazarov. “So that’s the standard we need to meet. And if we suddenly increase 10x the amount of data on the current system — yeah, it could work in some good conditions and it would be costly, and it would actually raise everybody’s costs, which is not something we believe in.”

But beyond the immediate effects, Nazarov believes that this upgrade will have more important effects in the future. “Really what you’re seeing here now is the Chainlink network growing into something that is going to do more and more off-chain computation.”

While that does not mean Chainlink will transition to building rollups and layer two solutions, Nazarov said there are three distinct services that the Chainlink network will soon provide. This includes verifiable randomness, a feature that has already been launched and that allows DApps to have a trusted source of random numbers, which could be particularly useful for gambling platforms and prediction markets. The other services, enabled by OCR, include keeper functions and fair sequencing, both solutions to very practical problems affecting DeFi.

Keepers are a type of maintainers necessary in smart contract environments. For example, some contracts require conducting periodic actions, which are normally triggered by the team or someone in the community — formalizing this behavior is what projects like Keep3r or Fetch.ai are trying to do.

Fair sequencing is a proposed service that aims to fix front-running and miner extractable value in DeFi. The issue arises when a blockchain operator can freely rearrange transactions to theirs or someone else’s benefit. For example, when they see a multi-million swap about to be confirmed on Uniswap, they can quickly place their transaction to benefit from a better price.

The OCR system enables more freedom in how computations are performed on the Chainlink network, enabling new kinds of services centered around computing data instead of publishing it. Nazarov said that these ideas come from very practical needs that are unaddressed in the current market. “We generally do not want to build the pieces of the stack that we do not have to build,” he said. “We want to be the maximally positive-enabling force for smart contracts, closing all the gaps in the stack that aren’t closed.”

Real Estate Giant Teams up with Gemini to Buy Bitcoin and Allow BTC Rent Payments

Republished by Plato

Published

on

Caruso, one of the largest estate companies in the US, has entered the BTC space with an undisclosed investment. The organization also revealed it will begin accepting bitcoin as payment for rent following a partnership with Gemini – the cryptocurrency exchange founded by the Winklevoss twins.

Pay Rent with Bitcoin

Without specifying the precise amount, Caruso announced earlier that it had made a “significant initial investment” in the primary cryptocurrency as part of its treasury management strategy. The move has made the company “the first to adopt the technology in the real estate industry.”

The firm completed the purchase through a partnership with Gemini, a US-based cryptocurrency exchange and custodian. The innovation reinforced the company’s confidence in the digitizing space.

Additionally, the firm enabled its tenants to pay rent with bitcoin, should they choose to do so.

Rick Caruso, founder, and CEO of the company weighed in on the topic:

”We believe that cryptocurrency is here to stay. We believe that bitcoin is the right investment for us. We’ve allocated a percentage of what would normally go into the capital market into bitcoin.”

The billionaire went further and stated crypto is a long-term resolution and ”it’s not about the next year or five years”.

”We are thrilled to partner with Caruso as they continue to push the real estate sector to new heights by embracing cryptocurrency for the benefit of both their customer experience and their own business operations. We are excited to help them execute their digital asset treasury strategy and advise them more broadly throughout their cryptocurrency journey.” – commented Gemini’s CEO Tyler Winklevoss.

The Los Angeles-based company has become a part of the growing institutional adoption of bitcoin around the globe. According to experts, companies like MicroStrategy, MassMutual, Tesla, and more are a vital factor behind BTC’s recent price increase.

Bitcoin as a Form of Payment

While Caruso may be the first firm from the real estate industry to adopt BTC as a payment method, companies from other sectors have well preceded it. Most recently, the popular NBA team Sacramento Kings said it will give the option to its players to receive their salaries in the primary cryptocurrency.

Another fresh example is the UK private jet company – PrivateFly. The organization revealed that nearly 20% of its yearly payments were paid in bitcoin.

Binance Coin, BitTorrent Token, Ontology Price Analysis: 10 April

Republished by Plato

Published

Binance Coin registered huge gains in the past few weeks. BitTorrent Token could consolidate before seeing recovery, while Ontology could face selling pressure if it falls out of the rising channel it was trading within.

Binance Coin [BNB]

From March 25 to April 10, at the time of writing, BNB has climbed from $225 to $473. Using the Fibonacci tool for its move from $225 to $356, where BNB had faced some resistance in early April, extension levels were plotted. These levels have been reached, and more ambitious targets for BNB lie in the $550 region.

It is not out of the question that BNB reaches these levels, especially with the BNB quarterly burning set for later this month. On the hourly, the RSI continued to stay above neutral 50 to show an uptrend in progress, and no divergence was seen. The Stochastic RSI was dropping toward oversold territory.

BitTorrent Token [BTT]

On the hourly chart, BTT broke out of a descending channel but was rejected at the $0.01 resistance level. Sometimes, breakouts from descending channel consolidate within a range before reaching toward the peak of the channel.

This could be what is happening for BTT. It has resistance at $0.01 and support at $0.0075. The breakout point at $0.0085 is also likely to serve as support.

Trading volume was trending downward. The Awesome Oscillator showed bearish pressure was present, although it was not strong.

Ontology [ONT]

ONT was also trading within a channel, but this one was ascending. Again, the short-term outlook placed ONT right beside a level of importance. There was resistance for ONT at the $2.05 level, and support from the lower boundary of the rising channel.

ONT began trading within this pattern about three days prior to the time of writing. A session close beneath the channel would likely see ONT face further selling pressure to take it to the base of the channel at $1.72. THE OBV has been on an uptrend in recent days but the MACD was beginning to drop.

IOTA co-founder discloses Coordicide’s release date

Republished by Plato

Published

on

The cryptocurrency market has seen the altcoins surge despite the correction witnessed in the short term. IOTA, the altcoin ranked 27th on CoinMarketCap, has grown dramatically on the charts right from the start of the month.

IOTA co-founder Dominik Schiener recently did one of his systematic AMA sessions. He elucidated some of the most important concepts about the development of IOTA and its updates, Chrysalis and Coordicide.

To begin with, Schiener answered a question about the challenges that IOTA 2.0 or Coordicide might face in its deployment process. One of the issues faced by the group of developers was to discover and fix bugs on major components.

The co-founder further shared his optimism on the progress in the AMA session.

“Coordicide will fully decentralize IOTA. On the theoretical side we are doing very well to deliver what is promised which is a fully decentralized IOTA. I think the biggest risk is the implementation.”

At this very moment, IOTA targetted Q4 of this year as a tentative date for Coordicide’s rollout. However, this depends largely on the results of the incentivized testnet, Schiener said:

“A lot of that will depend on how well the incentivized testnet goes, that’s why we always say that the incentivized test network is the most important part of Coordicide. That’s where the research combines with the implementation to test in an open environment.”

Furthermore, Schiener addressed concerns regarding data sharding. The Value Tangle team, just like the Coordicide team, reviewed all the “paths” and possible implementation of this component. Schiener stated:

“I think when it comes to sharding, if I had to sum it up, I think the biggest risk is going to be building a solution that is going to kill IOTA adoption. In a similar way of how they said the biggest risk to Ethereum is Ethereum 2.0.”

What’s interesting to note here, is the analogy with ETH and ETH 2.0. 

Keeping all the risks in mind, Schiener concluded:

“With that in mind, the team have received feedback from their corporate partners to create a solution that the market wants. In large part, Chrysalis will be the culmination of that feedback.”
