Solana news: The network’s post-quantum push reveals harsh tradeoff: security vs speed

Crypto has spent years obsessing over speed, fees and scalability. Now it may have to confront a more existential question: what happens when its core security breaks?

That question is moving from theory to urgency. Quantum computers, machines that use the principles of quantum physics to process information in fundamentally different ways than today’s computers, could eventually solve the kinds of mathematical problems that underpin modern encryption.

Discussions around post-quantum cryptography have intensified across the industry in recent weeks, especially after new research from Google and academic collaborators suggested that such systems could one day break widely used encryption, potentially cracking systems like Bitcoin’s in minutes rather than years.

While Bitcoin developers scramble to find a solution and Ethereum prepares for the event, Solana is trying to get ahead of that scenario.

Cryptography firm Project Eleven has teamed up with the Solana Foundation to experiment with post-quantum security, technology designed to withstand quantum attacks that could render today’s cryptography obsolete. The early work is already surfacing a difficult reality: making Solana quantum-safe may come at the expense of the performance that defines it.

In practice, that effort has meant moving beyond theory and into live testing. Project Eleven has worked with the Solana ecosystem to model how the network would behave if its current cryptography were replaced, including deploying a test environment using quantum-resistant signatures — the digital keys that authorize transactions. The goal is not just to prove the technology works, but to understand what breaks when it’s pushed to scale.

The early results show a clear tradeoff.

The new, quantum-safe “signatures” that approve transactions are much larger and heavier than those used today, roughly 20 to 40 times larger, Project Eleven CEO Alex Pruden, who founded the project, after years in crypto and venture capital, brings a mix of military and industry experience to the problem, told CoinDesk. That means the network can handle far fewer transactions at once. In testing, a version of Solana using this new cryptography ran about 90% slower than it does today, Pruden said.

That tradeoff cuts directly at the heart of Solana’s design. The blockchain has built its reputation on high throughput and low latency, positioning itself as one of the fastest networks in crypto. But post-quantum cryptography — while more secure against future threats — comes with heavier data and computational requirements, making it harder to maintain those speeds.

‘Pick any wallet’

Solana may also face a more immediate structural challenge than its peers.

Unlike Bitcoin and Ethereum, where wallet addresses are typically derived from hashed public keys, Solana exposes public keys directly. That difference matters in a quantum scenario. “In Solana, 100% of the network is vulnerable,” Pruden said.

“A quantum computer could pick any wallet and immediately start trying to recover the private key.”

Pruden, a former Army Green Beret, first became interested in Bitcoin while deployed in the Middle East, later worked at Coinbase and joined Andreessen Horowitz’s venture team on its first fund. He then became an early leader at privacy-focused blockchain Aleo before launching Project Eleven, a firm focused on preparing digital assets for what he calls “Q-day,” the moment quantum computers can break today’s cryptography.

Some developers in the Solana ecosystem, meanwhile, are looking at simpler, more immediate fixes. One example is something called ‘Winternitz Vaults’, which uses a different kind of cryptography that’s believed to be safer against quantum attacks. Instead of changing the entire network, these tools focus on protecting individual wallets, giving users a way to secure their funds now while bigger, system-wide upgrades are still being figured out.

Despite those hurdles, Solana has moved faster than much of the industry in at least one respect: experimentation. “There’s something tangible,” Pruden said. “We actually have a testnet with post-quantum signatures.” He added that the Solana Foundation “deserves credit for at least engaging and wanting to do the work.”

Across crypto, that level of engagement remains rare. While some ecosystems, most notably Ethereum, have begun discussing long-term migration paths, concrete implementation has been limited.

The broader challenge is not just technical, but social: upgrading cryptography in decentralized systems requires coordination across developers, validators, applications and users, all of whom must move in sequence.

For Pruden, the risk is that the industry waits too long to begin that process. “This is a tomorrow problem — until it’s today’s problem,” he said. “And then it takes four years to fix.”

Metaplanet Outperforms MicroStrategy in Q1 Bitcoin Acquisition Using Options-Based Treasury Strategy

Published

on

Brian Armstrong's Bold Prediction: AI Agents Will Soon Dominate Global Financial

TLDR:

  • Metaplanet added 5,075 BTC to permanent holdings in Q1 through a structured options income rotation system.
  • The firm generated $18.63 million in options income, reducing its net Bitcoin cost to roughly $76,227 per coin.
  • MicroStrategy acquired 89,599 BTC at $80,929 average, while Metaplanet’s net cost came in nearly $4,700 lower.
  • Metaplanet separates Bitcoin into two buckets — income generation and long-term holdings — never mixing the two.

Metaplanet, the Japanese hotel company turned Bitcoin treasury firm, has drawn attention after shifting to quarterly Bitcoin purchase announcements.

The company added 5,075 BTC to its permanent holdings in Q1 2025. Its average purchase price came in near $79,898.

Meanwhile, a detailed breakdown from a prominent analyst suggests the firm may have outperformed MicroStrategy, widely regarded as the benchmark for corporate Bitcoin acquisition.

Metaplanet’s Two-Bucket Bitcoin System Explained

Metaplanet reportedly operates two distinct Bitcoin buckets. One is dedicated to income generation, and the other holds long-term Bitcoin positions.

According to analyst Ragnar, the two buckets remain strictly separate. Long-term holdings are never exposed to options contracts under this structure.

The income generation bucket works through a rotation of cash-secured puts and covered calls. When the team holds cash, they sell put options below the current Bitcoin price.

If Bitcoin stays above the strike price minus the premium, the puts expire and the premium is collected. This process repeats weekly, compounding returns over the quarter.

If Bitcoin falls below that threshold, Metaplanet gets assigned and acquires Bitcoin below market price. At that point, the team pivots to selling covered calls against those holdings.

The calls either expire, generating more premium, or get assigned, returning the position to cash and restarting the cycle.

At the quarter’s close, the team transfers the accumulated Bitcoin into the permanent holdings bucket. This transfer marks the official addition to their long-term treasury, which is what gets announced publicly each quarter.

Q1 Numbers Show Metaplanet Acquired Bitcoin Cheaper Than MicroStrategy

The Q1 figures offer a clearer picture of performance. Metaplanet generated $18.63 million in income from its options activity during the quarter.

Dividing that by the 5,075 BTC added to permanent holdings gives roughly $3,671 of income per Bitcoin acquired.

Ragnar’s post breaks this down further. Subtracting the income generated from the average purchase price of $79,898 brings the effective net cost to approximately $76,227 per Bitcoin.

That figure excludes direct capital deployment and accounts only for options-based income offsetting acquisition costs.

By comparison, MicroStrategy purchased 89,599 BTC in Q1 at an average price of $80,929. That puts Metaplanet’s net cost roughly $4,700 lower per Bitcoin when income generation is factored in. Even without that adjustment, Metaplanet still came in around $1,000 cheaper per coin.

Ragnar noted that Metaplanet achieved this result while its preferred share structure still awaits approval. The analyst added that he remains more bullish on the company following this analysis, though he clarified the post represents personal speculation pending confirmation from the Metaplanet team.

Free Bitcoin Again? Block Revives Faucet Under Jack Dorsey

Free Bitcoin Again? Block Revives Faucet Under Jack Dorsey

Block plans to revive the Bitcoin “faucet” model on April 6 through a new site, btc.day, as Jack Dorsey pushes another public effort tied to Bitcoin access and education. 

Summary

  • Block will relaunch the Bitcoin faucet on April 6 through a new countdown site, btc.day.
  • The company has not disclosed claim rules, eligibility, or total Bitcoin set for distribution yet.
  • Dorsey’s rollout revives Gavin Andresen’s 2010 faucet model, which once gave users five Bitcoin.

The site already shows a countdown timer, an orange faucet symbol, and the phrases “The Faucet is Back” and “Buy, Secure, Spend.”

Dorsey announced the move on Friday through an update tied to Bitcoin at Block. The company said the faucet will return through btc.day, though it has not yet shared the full rules for how users will claim free Bitcoin.

The website does not currently ask users to complete any task. It only shows a timer and basic branding linked to the old faucet idea. Block has also not said how much BTC it plans to distribute.

The faucet model dates back to 2010, when software developer Gavin Andresen used it to introduce people to Bitcoin. His original site gave users five BTC after they completed a captcha and entered a wallet address.

At that time, Bitcoin was new and had little public reach. Early builders used simple tools like faucets to help people test wallets, send coins, and learn how the network worked. The model later became part of Bitcoin’s early history.

In addition, the new rollout appears to borrow from that original approach. By bringing back the faucet concept, Block is linking a modern campaign to one of Bitcoin’s best-known early distribution methods.

The company has not confirmed whether the new version will use captchas, wallet checks, or any other participation step. It also has not said whether the giveaway will be open globally or limited to specific users or regions.

Community watches for more details

Crypto users have started discussing the relaunch across social platforms. Some described the move as a way to keep Bitcoin more accessible, while others pointed to the larger number of wallet users today compared with 2010.

The market is now waiting for details on the size, timing, and structure of the giveaway. Block held 8,883 BTC as of its accumulation record dating back to October 2020, but neither Dorsey nor the company has said how much of that Bitcoin, if any, will be used for the faucet.

Why Bearish Bets and ETF Flows May Spark a Rally

Why Bearish Bets and ETF Flows May Spark a Rally

Key takeaways:

  • Bitcoin hitting $72,000 would liquidate $2.5 billion in shorts, potentially crushing bears who are overleveraged.

  • Iran’s war and high oil prices currently pressure BTC, but a ceasefire or ETF inflows could spark a rapid recovery.

$2.5 billion in shorts at risk if BTC hits $72,000

Bitcoin (BTC) has consistently failed to hit new highs since attempting to reclaim the $75,000 level since March 17.

Bearish Bitcoin futures bets have been piling up as the war in Iran pushed oil prices to their highest levels since June 2022. However, two events could propel Bitcoin to $72,000 in the coming weeks and help cement a sustainable bull run.

According to Coinglass estimates, a total of $2.5 billion in short positions on Bitcoin futures will be liquidated if Bitcoin rises just 7.5% to $72,000 from the current $67,100 level.

BTC bears benefit from miners’ sales, weak S&P 500

Bears have been adding shorts since March 25, when Iran reportedly refused to negotiate a ceasefire. Additional selling pressure emerged as MARA Holdings (MARA US) announced it sold 15,133 BTC on March 26. The publicly listed Bitcoin miner shifted its focus to AI computing and chose to reduce its Bitcoin holdings to pay down debt.

After peaking near 7,000 points on Jan. 28, the S&P 500 dropped 10% by March 30. Investors fear recession risks because central banks have less room to cut interest rates due to inflation.

Oil prices have jumped over 70% since the war in Iran started in late February, which hikes logistics costs and cuts into consumer spending.

Traders are pricing in 89% odds that the Fed will keep interest rates steady through September, with 5% odds of a hike to 4%.

In early March, bond futures showed the opposite, with 79% odds of rate cuts. Returns on fixed-income investments will likely stay attractive for longer.

Meanwhile, confidence among Bitcoin bears has increased, as reflected by the negative funding rate in perpetual futures contracts.

In neutral market conditions, longs usually pay to keep positions open, causing this indicator to range between 5% and 10% to compensate for capital costs.

Negative funding rates signal a lack of demand for bullish leveraged bets and potential overconfidence from the bears.

Ceasefire or economic weakness may boost Bitcoin

While it is impossible to predict the outcome of the war involving Iran, a ceasefire agreement could spark bullish sentiment and catch bears by surprise.

Bitcoin jumped from $69,150 to $74,900 during the five days ending March 16 after US-listed Bitcoin exchange-traded funds saw $1.5 billion in net inflows over two weeks. If ETF inflows resume, Bitcoin could also reclaim the $72,000 level.

US President Donald Trump has asked Congress to boost defense spending to $1.5 trillion, according to a 2027 budget proposal released Friday. These plans include a 10% cut in other areas to offset military expenses.

Trump reportedly said at a private White House event on Wednesday: “We’re fighting wars. We can’t take care of day care,” according to CNBC.

If the US economy loses steam, or if private credit redemptions continue to pressure the market, investors will likely look for alternative hedges.

Consequently, Bitcoin’s appeal would grow as the it presently trades 47% below its all-time high. Thus, a bull run to $72,000 might happen regardless of how long the war in Iran lasts.
