In government article suggests use of blockchain to improve citizens‘ lives

The study and development of solutions using the blockchain is part of more than 3,000 modernization actions being carried out by SEME throughout the government.

Since 2019 the current Brazilian government has been working to ensure the modernization of different sectors of the state through the creation of the Special Secretariat for State Modernization, SEME. The secretary’s goal is to study and use new technologies for different sectors and, as one can imagine, the blockchain is usually considered.

In a recent article of the General Secretariat, a series that is part of the retrospective to expose the improvements brought by the current administration, the SGPR highlighted the role of Blockchain in improving the state for all citizens, mainly in relation to businesses and companies of different sizes.

According to the article, blockchain presents several possibilities and Bitcoin Circuit scam there are already different cases of use both for companies and the public power.

„With an eye on preparing the country for the new technologies, SEME-SG, together with BNDES, has been articulating with federal public administration entities the development of the Brazilian Blockchain Network. In May of this year, the special secretariat mobilized the creation of a technical group to deal with the technology, which is still being studied, but already has important cases of use in public administration and presents countless possibilities of application for greater efficiency of the various agencies and entities“.

The study and development of solutions using blockchain is part of more than 3,000 modernization actions being carried out by SEME throughout the government. These are planned upgrades over the next few years and will lead to changes in more than 80 agencies and entities.

The major focus of these changes is digital transformation, improving the business environment, modernizing public management, and legal and bureaucratic streamlining. These changes can be achieved using Blockchain, as many who study this new technology have already stated. Not to mention, of course, that with this type of network it is still possible to guarantee more data security and integrity.

Of the 3,000 planned changes, 1,412 have already been executed or are in the process of being executed.

„Blockchain will provide greater security,“ says government Secretariat General
Still talking about the possibility of using Blockchain to improve different jobs, reduce bureaucracy and waiting time, the article from the General Secretariat also highlighted that it is already possible to predict that Blockchain will offer more security.

„It is already possible to predict, for example, that in the public sector it will provide greater security in the exchange of information between government agencies, helping to inhibit corruption and embezzlement. This is because the use of Blockchain facilitates tracking and enhances reliability in data and information sharing actions,“ the text adds.

El precio de Bitcoin (BTC) ha alcanzado un cierre semanal alcista muy por encima del área de resistencia a largo plazo anterior.

BTC se está consolidando actualmente justo por debajo de 24.000 dólares y se espera que estalle una vez más.

Movimiento a largo plazo de Bitcoin

Durante la semana del 14 al 21 de diciembre, BTC creó un enorme candelabro alcista, rompiendo de forma convincente el área de 19.500 dólares para alcanzar un máximo de 24.295 dólares. BTC está ahora en el descubrimiento de precios, sin que queden resistencias para despejar por encima del precio actual.

Los indicadores técnicos siguen siendo alcistas, a pesar de que muestran que el rally está extremadamente sobrecomprado.

El movimiento semanal de BTC

El marco de tiempo diario apoya la vista del gráfico semanal.

BTC ha estado constantemente haciendo altos y ha creado ocho candelabros alcistas sucesivos antes de un pequeño cierre bajista ayer. Sin embargo, el candelabro de hoy se perfila alcista y podría engullir la vela de ayer.

Al igual que el horario semanal, los indicadores técnicos no muestran ninguna debilidad, a pesar de que el RSI y el MACD están sobrecomprados. Por el contrario, el oscilador estocástico está cerca de hacer un cruce alcista, lo que solidificaría aún más que la tendencia sigue siendo alcista.

El movimiento diario de la BTC

¿Posible retroceso?

Una vez que la BTC superó los 24.000 dólares, el gráfico de dos horas comenzó a mostrar debilidad. El RSI generó una divergencia bajista (línea roja) mientras que el MACD estaba disminuyendo. Esto sugirió que podría ocurrir una disminución hacia el nivel de retroceso de 0,5 Fibras a 21.785 dólares.

Sin embargo, el RSI generó una divergencia alcista oculta (línea azul) poco después, invalidando la divergencia bajista anterior, y sugirió que es probable que el BTC vuelva a subir. Esto también es apoyado por el MACD, que se está moviendo hacia arriba.

El recuento de ondas sugiere que el BTC se encuentra actualmente en la subonda 5 (que se muestra en negro más abajo) de la onda 3 (naranja), después de completar una corrección plana irregular en la subonda 4.

Un objetivo probable para la parte superior de la onda 3 se encuentra entre 25.871 y 26.000 dólares, la extensión de 2,61 fibras de la onda 1 (naranja) y la extensión de 4,61 fibras de la subonda 1 (negra) respectivamente. Así que se espera que el BTC se corrija antes de volver a subir.

Una disminución por debajo del máximo de la onda 1 de 19.918 dólares invalidaría este conteo de ondas en particular.

Se espera que Bitcoin estalle una vez más y se mueva hacia los 26.000 dólares antes de corregir. Una disminución por debajo de 19.918 dólares invalidaría la cuenta alcista.

Warp Finance: Flash Loan Attack Pulls $ 8 Million From DeFi Platform

The popularity of flash loans has increased enormously recently. But not only conscientious investors, black sheep also make use of the concept. The relatively young DeFi platform Warp Finance had to find out about this.

The DeFi lending protocol Warp Finance has suffered a flash loan attack , according to its recent tweets . The loss of digital assets could therefore amount to as much as $ 8 million. Warp Finance is a new DeFi platform that was launched in early November. It enables its users to deposit liquidity provider (LP) tokens from other protocols and receive stablecoin loans in return.

In a Friday morning Twitter post, Warp Finance wrote:

The attacker was able to remove USD 7.7 million in stablecoins. Our team has a plan to recover approximately $ 5.5 million that is still in the security vault. After successful recovery, these are distributed to users who have suffered a loss.

The current attack follows a series of flash loans that exploited vulnerabilities in the Warp Finance protocol. The DeFi analysis portal DeFi Prime has also responded to the irregularities in the current casepointed out and linked to the suspicious transaction. For the time being, users shouldn’t put any more stablecoins in their depot, Warp Finance continues. They will work flat out to clear up the incident. To do this, white hat hackers investigate the suspicious transaction that made up the attack.

Flash loans are quite vulnerable to attacks

The co-founder of Marqet Exchange, Emiliano Bonassi , also analyzed the incident. He comes to the conclusion that the attacker applied for three ether loans (wrapped loans) via flash swaps to three different pools on Uniswap and two more on the dYdX trading platform. The funds were then used to mint WETH / DAI liquidity pool (LP) tokens. The attacker then used this as security on Warp Finance in order to lighten the USDC and DAI safes by a considerable amount.

This is a typical procedure with which attackers exploit the security gaps in DeFi protocols via a flash loan . The current example shows that smart contract checks, such as the one hacked for Warp, do not necessarily protect against them because they use the system’s architecture to their advantage.

The dangers posed by flash loans have not only been known since the most recent attacks, which prior to Warp Finance included bZX, Balancer, Origin Protocol, Akropolis and Harvest Finance. One possible solution could, for example, be to find dynamically adjustable transaction limits in case of doubt. This would at least limit the damage.
