Circle future-proofs Arc blockchain against quantum threats

Move over, legacy crypto. Circle’s Layer-1 blockchain Arc, built for stablecoin finance and institutional use, will debut with quantum-resistant features designed to survive a future in which traditional blockchains could crumble under quantum attacks.

“At mainnet, Arc will introduce a post-quantum signature scheme, giving users a practical design path to create quantum-resistant wallets,” Arc said in an update Thursday. The update didn’t mention the timeline for the mainnet launch.

It means that Arc is baking in quantum resistance from day one, unlike legacy chains, which may be waiting to add this feature later as a patch. So, when users create a wallet on the mainnet, they can choose a signing method that future quantum computers cannot break. This will ensure the long-term security and protection of crypto assets in wallets.

Every blockchain wallet relies on a digital signature or a super-secure key to prove you own your tokens and authorize transactions. When you hit “send” on your crypto, your wallet signs the transaction with this code, and the network verifies it before moving the coins. Today’s computers aren’t powerful enough to exploit this process, access your key, and drain your coins.

However, a future quantum computer could do so in at least two ways – a long attack and a short attack, as CoinDesk explained Sunday.

In short, what appears unbreakable today may not be tomorrow, which is what Arc is offering a quantum-resistant signing method right of the bat.

Arc’s announcement comes as Google’s report on quantum threats to Bitcoin and Ethereum’s blockchains stirs fresh questions about the long-term reliability of digital ledgers. Developers, however, have been tackling the issue for months, proposing early solutions. At the same time, startups like Postquant Labs are exploring how quantum hardware could actually strengthen blockchain networks.

Arc’s choice to build quantum resistance from the ground up could make it especially attractive to institutions. The blockchain kicked off its testnet in October, using Circle’s dollar-pegged stablecoin USDC as the native currency for gas fees. USDC, with a market cap of around $77.5 billion, trails only tether in size and stands out as a regulated stablecoin favored by institutions.

Arc’s roadmap also includes ensuring that sensitive financial information remains private in the quantum era. Its near-term plan focuses on protecting private balances, confidential payments, and recipient information with quantum-resistant cryptography, not just quantum-resistant wallet keys. This way, the confidential financial activity of institutions using Arc will remain private.

The mid-term phase will focus on closing the backdoors through which a quantum attack could occur. These backdoors are the cloud servers validators run on, the hardware security modules that store keys, and the encrypted connections between nodes. This is akin to fortifying an entire building, not just the safe in your room closet.

In the long term, Arc will focus on the validator layer. Validators are the computers — run by trusted institutions — that confirm transactions and add new blocks to the distributed ledger.

Arc’s current design finalizes a block in under a second, according to the official blog. This leaves a future quantum attacker an extremely small window of time to derive a user’s private key and forge a signature. The risk, therefore, is small, but Arc is not ignoring it.

“Arc’s roadmap is expected to target validator signature hardening after rigorous performance testing and the necessary tooling support are in place. Validator upgrades should happen when they are ready to preserve both resilience and network performance,” it said.

Price Prediction for SPX, DXY, BTC, ETH, BNB, XRP, SOL, DOGE, HYPE, ADA

Price Prediction for SPX, DXY, BTC, ETH, BNB, XRP, SOL, DOGE, HYPE, ADA

Key points:

  • Bitcoin rose above the $70,000 level on Monday, but analysts remain skeptical, expecting a drop below the $60,000 support.

  • Several major altcoins have bounced off their supports, indicating demand at lower levels.

Buyers pushed Bitcoin (BTC) above the $70,000 level, but failed to sustain the breakout. That suggests the bears have not given up and are trying to retain control. Select analysts believe that BTC is likely to dip below its $60,000 low before bottoming out.

Another negative view came from Glassnode, which said in its recent report that its Long-Term Holder Realized Loss metric, which tracks losses locked in by investors who held coins for more than six months before selling, suggests the selling pressure may not have exhausted. The 30-day simple moving average of the indicator at $200 million per day needs to drop to levels below $25 million for the base formation to begin.

Among all the bearishness, there is a silver lining for the bulls. According to crypto sentiment platform Santiment, social media platforms recorded five bearish BTC comments for every four BTC bullish comments, the most since Feb. 28.

That is a good sign as markets typically move in the opposite direction of the crowd’s expectation, suggesting “things can turn positive sooner rather than later,” Santiment added.

Could buyers extend the recovery in BTC and the major altcoins? Let’s analyze the charts.

S&P 500 Index price prediction

The S&P 500 Index (SPX) has pulled back to the 20-day exponential moving average (6,601), indicating solid buying at lower levels.

Sellers will attempt to halt the recovery at the 20-day EMA, but if the bulls prevail, the index may rise to the 50-day simple moving average (6,777). Sellers are expected to pose a strong challenge at the 50-day SMA.

On the downside, the bears will have to yank the price below the 6,316 level to signal the resumption of the corrective phase. The next support to watch out for on the downside is the 6,147 level.

US Dollar Index price prediction

The US Dollar Index (DXY) is stuck between the 20-day EMA ($99.59) and the 100.54 overhead resistance.

Sellers are attempting to pull the price below the 20-day EMA. If they can pull it off, the index may decline to the 50-day SMA (98.44). That suggests the index may trade inside the large range between 95.55 and 100.54 for a while longer.

Buyers will have to maintain the price above the 20-day EMA to retain control. If they do that, the possibility of a break above the 100.54 level increases. The index may then start a new up move to the 102 level and subsequently to the 103.54 level.

Bitcoin price prediction

BTC closed above the moving averages on Sunday, indicating that the bulls are attempting a comeback.

The flattish moving averages and the relative strength index (RSI) near the midpoint do not give a clear advantage either to the bulls or the bears. If the price sustains above the moving averages, the bulls will attempt to drive the BTC/USDT pair above the $72,000 resistance. If they succeed, the BTC price may reach the $74,508 to $76,000 resistance zone.

Sellers are likely to have other plans. They will strive to pull the pair below the support line, invalidating the bullish setup. That opens the doors for a decline to the $62,500 to $60,000 support zone.

Ether price prediction

Ether (ETH) closed above the moving averages on Sunday, clearing the path for a rally to the $2,200 resistance.

Sellers will attempt to halt the recovery at the $2,200 level, but if the buyers pierce the resistance, the ETH/USDT pair may march to the $2,400 resistance. The bulls will have to propel the ETH price above the $2,400 level to start a sustained recovery to $2,800 and then to $3,050.

Alternatively, if the ETH price turns down sharply from the $2,200 level and breaks below the moving averages, it suggests that the pair may consolidate for some time. The support of the range is at the $1,916 level.  

BNB price prediction

BNB’s (BNB) bounce off the $570 level has reached the moving averages, where the bears are expected to step in.

If the price turns down sharply from the moving averages, the BNB/USDT pair risks breaking below the $570 level. If that happens, the BNB price may resume the downtrend and plummet to the $500 level.

Instead, if buyers drive the price above the moving averages, it suggests that the pair may extend its stay inside the $570 to $687 range for a few more days. Buyers will be back in the driver’s seat on a close above the $687 level.

XRP price prediction

XRP (XRP) turned up from the crucial $1.27 support on Sunday, indicating that the bulls are aggressively defending the level.

The bulls will have to secure a close above the 50-day SMA ($1.39) to improve the prospects of a rally to the $1.61 level and later to the downtrend line of the descending channel pattern. 

On the contrary, if the XRP price turns down sharply from the moving averages and breaks below $1.27, it suggests that the bears remain in control. The XRP/USDT pair may plunge to the $1.11 level and eventually to the support line near the $1 level.

Solana price prediction

Solana (SOL) has been oscillating inside the $76 to $98 range for several days, indicating a tough battle between the bulls and the bears.

If buyers push the price above the moving averages, the SOL/USDT pair may ascend to the $98 resistance. Sellers are expected to fiercely defend the $98 level in an attempt to keep the SOL price inside the range. 

The next trending move is expected to begin on a close above $98 or below $76. If buyers thrust the price above the $98 resistance, the pair may surge to the $117 level. Conversely, a close below the $76 support might sink the pair to the $67 level.

Dogecoin price prediction

Dogecoin (DOGE) remains stuck inside a tight range between the 50-day SMA ($0.09) and the $0.09 level, signaling a balance between supply and demand.

Buyers will gain the upper hand on a close above the moving averages. The DOGE/USDT pair may rally to the $0.11 level and subsequently to the $0.12 resistance. If the price turns down from the overhead resistance, the pair may swing between $0.12 and $0.09 for a while.

If the DOGE price turns down from the moving averages and breaks below the $0.09 level, it signals that the bears have seized control. The pair may slump to the $0.08 level and thereafter to the $0.06 level.

Hyperliquid price prediction

Buyers are attempting to maintain the Hyperliquid (HYPE) price above the 20-day EMA ($37.03) but are facing strong resistance from the bears.

If the HYPE price closes above the 20-day EMA, it suggests that the lower levels continue to attract buyers. The HYPE/USDT pair may then rally to $41.59 and, after that, to the $44 level.

This positive view will be negated in the near term if the price turns down and breaks below the 50-day SMA ($34.48). The pair may then witness a deeper correction to the $30 level.

Cardano price prediction

Cardano (ADA) closed above the $0.25 level on Sunday, signaling that the bears are losing their grip.

ADA/USDT daily chart. Source: Cointelegraph/TradingView

There is resistance at the 50-day SMA ($0.26), but if the bulls overcome it, the ADA/USDT pair may reach the downtrend line of the descending channel pattern. Sellers are expected to defend the downtrend line, as a close above it signals a potential short-term trend change.

The $0.22 level is the crucial level to watch out for on the downside. If the support breaks down, the ADA price may start the next leg of the downtrend to the support line near the $0.16 level.
