Blockchain Bulletin: December 2025
Beldex Obscura Upgrade Brings Smaller, Faster Private Transactions
Beldex has rolled out a major upgrade called Obscura and has gone live on 7 December 2025 at block height 4,939,540. This is the network’s 20th hardfork, and its biggest focus is on better scaling through Bulletproofs++.
Bulletproofs++ are advanced privacy proofs that make transactions about 38% smaller than before. This means lighter blocks, faster checks, and more transactions fitting into each block.
Over the years, Beldex has moved from Proof of Work to Proof of Stake in 2021, and added private digital names with the Bern hardfork in 2024. Obscura builds on these changes by keeping strong privacy while cutting down blockchain data growth. The upgrade also lowers costs for masternode operators and prepares Beldex for wider use and long-term growth, especially for privacy-first apps.

Solflare has launched Solflare Shield, a new NFC-enabled hardware wallet made for mobile-first Solana users. Announced on 4 December 2025 in Zagreb, the wallet lets users sign transactions by simply tapping a card to their phone.

The wallet comes in three versions: Shield Origin (minimal and affordable), Shield Signature (artist-designed), and Shield Unique (fully custom). Prices range from $49 to $79, with shipping starting on 1 February 2026.
AllScale Raises $5m to Build a Self-Custody Stablecoin Neobank
AllScale has raised $5 million in seed funding to build what it calls the world’s first self-custody stablecoin neobank. The round was led by YZi Labs through its EASY Residency Season 2 programme, with support from Informed Ventures, Generative Ventures, and other major investors. AllScale is also an official ecosystem partner of BNB Chain.
The platform is built for microbusinesses, freelancers, and SMBs that struggle with slow, costly, or restricted traditional banking. AllScale lets users send and receive stablecoin payments in minutes, without a bank account or complex crypto keys.
It uses self-custody wallets, simple passkeys instead of seed phrases, and tools for invoicing and payouts. Already active in Africa, AllScale plans to expand into Latin America, helping unbanked users and the growing freelance economy access fast, borderless payments.
Gamdom Sets 100% RTP on All Original Crypto Casino Games
Gamdom has rolled out a major update to its original crypto casino games, setting the Return to Player (RTP) at 100% across the entire lineup. This means there is now zero house edge, and over time, players are expected to get back everything they wager. The change applies to popular games like Dice, Mines, Plinko, Crash, Keno, Roulette, and Hi-Lo.
RTP provides how much a game pays back on average. Most online casino games sit around 95–97%, but Gamdom has removed its margin completely for its in-house titles. All Gamdom Originals also use provably fair systems, support major cryptocurrencies like BTC, ETH, and USDC, and offer adjustable risk levels with high multipliers. The update focuses on fairness, transparency, and better long-term value for players in a crypto-native gaming environment.
