Storytelling is evolving with the convergence of AI, blockchain, and intellectual property. Black Mirror’s experimentation with blockchain is leading the way for the future of entertainment monetization.

Traditional storytelling is no longer meeting the expectations of digital-native audiences. The rise of new technologies is reimagining how entertainment intellectual property is created and consumed.

Blockchain is revolutionizing the entertainment industry by providing a new layer of structure. It enables on-chain IP verification, composable rights, community ownership, and tokenized incentives for creators and fans.

Black Mirror has partnered with Pixelynx Inc. and KOR Protocol to bring the Black Mirror universe on-chain. Their latest initiative involves a token inspired by the Nosedive episode, where fans can earn exclusive experiences and rewards based on their social and wallet interactions.

The future of entertainment lies in embracing blockchain technology to create interactive, tokenized, and on-chain content. This shift marks the beginning of a new era for intellectual property – one defined by protection, participation, and sustainable monetization.

– Shivani Phull, CFO, Pixelynx Inc.

In Ask an Expert:
– Web3 ownership is more about participating in a system than just holding an asset.
– Reputation-based tokens can create economic value from behavior but introduce performance-based risk.
– These tokens can act as a new form of engagement yield for younger investors.

Solana Quietly Fixes Bug That Could Have Let Attackers Mint and Steal Certain Tokens

The Solana Foundation has revealed a security vulnerability in its privacy-focused token system that could have allowed attackers to create fraudulent zero-knowledge proofs, enabling unauthorized minting or withdrawals of tokens.

The vulnerability was reported on April 16 through Anza’s GitHub security advisory, along with a proof-of-concept. Engineers from Solana development teams Anza, Firedancer, and Jito confirmed the bug and immediately started working on a solution, as detailed in a post-mortem published on Saturday.

The issue originated from the ZK ElGamal Proof program, which validates zero-knowledge proofs (ZKPs) used in Solana’s Token-22 confidential transfers. These extension tokens secure private balances and transfers by encrypting amounts and using cryptographic proofs for validation.

ZKPs are a cryptographic technique that allows someone to prove knowledge or access to something, like a password or age, without disclosing the information itself. In cryptocurrency applications, they can demonstrate a transaction’s validity without revealing specific amounts or addresses, which can be exploited by malicious actors.

The bug occurred due to missing algebraic components in the hashing process during the Fiat-Shamir transformation, a method to make zero-knowledge proofs non-interactive. A sophisticated attacker could create invalid proofs that the on-chain verifier would accept.

This vulnerability could have enabled unauthorized actions such as unlimited token minting or withdrawals from other accounts. However, standard SPL tokens or the main Token-2022 program logic were unaffected.

Patches were privately distributed to validator operators starting on April 17, with a second patch released later that day to address another related issue in the code. Third-party security firms, including Asymmetric Research, Neodyme, and OtterSec, reviewed both patches. By April 18, a supermajority of validators had implemented the fix.

There is no evidence that the bug was exploited, and all funds remain secure, according to the post-mortem.

Solana Surges 8% Despite Global Macro Tensions. Can It Hit $155 in Short-Term?

Geopolitical tensions and evolving trade policies are continuing to influence the cryptocurrency markets, with Solana standing out amidst global economic uncertainty. SOL has demonstrated remarkable recovery strength, rising 8% from its low of $140 on April 30 to around $152, alongside a 35% increase in daily trading volume. This resilience comes at a time when US-China trade relations are deteriorating, impacting both traditional and digital asset markets.

In the broader context, the CoinDesk 20 Index also saw a 4% increase on Thursday.

Key highlights from the technical analysis of SOL include a recovery from a 7.4% correction on April 30, establishing strong support at 140.65 and reaching new period highs at 152.69. The trading range of 12.04 points reflects volatility, with volume analysis showing increased trading during the correction followed by sustained buying interest during the recovery.

Recent price action suggests an ascending channel with resistance at 152.50 and key support at the 148.50-149.50 zone. Bullish momentum seems sustainable with higher lows indicating potential movement towards the 155.00 psychological level. Notably, SOL experienced significant volatility within a short timeframe, but key support was established at 151.10 with strong institutional interest observed during mid-session rally.

Bitcoin Debate on Looser Data Limits Brings to Mind the Divisive Ordinals Controversy

Bitcoin developers are once again at odds over how the world’s oldest and largest blockchain should handle storing information on-chain. A proposal to relax long-standing limits on the size of data held has sparked fierce debate reminiscent of past battles over Ordinals.

The blockchain’s OP_RETURN feature allows people to attach a small piece of extra data to a transaction, often used for things like notes, timestamps, or digital records. The proposed change, presented by developer Peter Todd, would remove the 80-byte cap on such data. This limit was originally implemented to discourage spam and maintain the blockchain’s financial integrity.

Supporters argue that the current limit is ineffective as users are already bypassing it using Taproot transactions to hide data inside parts of the transaction meant for cryptographic signatures. This is how Ordinals and Inscriptions work, embedding images or text into Taproot transactions that are often unspendable, effectively turning the Bitcoin blockchain into a data storage system.

Bitcoin Core developer Luke Dashjr, a vocal critic of Ordinals, has labeled them a “spam attack” on the blockchain. He called the proposal “utter insanity” and expressed concern that loosening data restrictions would further degrade Bitcoin’s financial-first purpose.

Critics also worry that the change could normalize illegal content storage, degrade the chain’s fungibility, and potentially turn node operators into unwitting hosts of malware and copyright violations. For example, one Ordinals team inscribed a whole Nintendo 64 emulator onto the blockchain, raising concerns about copyright infringement.

Supporters of the change, including Pieter Wuille and Sjors Provoost, argue that relaxing OP_RETURN limits could actually reduce UTXO bloat, a phenomenon that slows down the blockchain when cluttered with non-financial transactions and mempool fragmentation.

For now, the proposal is under review, demonstrating that the battle for Bitcoin’s identity is ongoing. The intensity of the debate on GitHub and blockchain developer mailing lists shows that this issue is far from resolved.
