Dapp

Dapps are digital applications that run on a P2P network of computers rather than a single server, typically utilizing smart contracts to ensure transparency and uptime. In 2026, Dapps have achieved mass-market appeal through Account Abstraction, allowing for a "Web2-like" user experience with the security of Web3. This tag covers the entire ecosystem of decentralized software—from social media and productivity tools to governance platforms and identity management.

Retail Is Doing the Same with Bitcoin Hyper

Retail Is Doing the Same with Bitcoin Hyper

The post Retail Is Doing the Same with Bitcoin Hyper appeared on BitcoinEthereumNews.com. Strategy continues to dominate as the world’s largest corporate Bitcoin holder as the company announces another $BTC purchase amid falling prices. Michael Saylor’s investment company issued a press release stating it had bought another 850 $BTC for $99.7M, averaging out at $117K per Bitcoin. Today, Strategy holds over $72B in $BTC and shows no signs of slowing down even in a rocky crypto market. To achieve the accumulation, Strategy sold nearly $100M of its own stock, showing serious confidence in the future of Bitcoin even though the gap from its recent ATH of $124K has widened, with the $BTC price down at $113K. It’s that same investor confidence in Bitcoin that’s seeing a new token – Bitcoin Hyper ($HYPER) – rack up massive funds in its presale. With plans to introduce a revolutionary Layer-2 designed to unleash Bitcoin’s full potential, $HYPER has grabbed the attention of retail investors. Why is Strategy Buying Bitcoin Now? Strategy (listed on the Nasdaq as MSTR) stocks hit a five-month low at around $320 in early September, prompting a shift towards $BTC, which is outperforming MSTR. While MSTR has seen a 6.2% decline over the last month, $BTC has seen only a 1.6% loss in the same period. While retail investors are spooked by the volatile performance of $BTC, following its fall from a recent ATH, institutional investors like Saylor believe the dip is an opportunity to scoop up cheap Bitcoin that will inevitably rise after the current period of volatility is over. Source: X/@saylor As we can see, Strategy has an overall purchase history that reflects this attitude. Even during the crypto lull in 2022, Strategy continued dollar-cost averaging its Bitcoin reserves, expecting that the industry would recover. This isn’t the first time Strategy has sold its own stock to purchase $BTC, either. Saylor’s…

Secure On-chain Randomness By Oasis Is A Great Way To Answer The Blockchain Need For RNG

Secure On-chain Randomness By Oasis Is A Great Way To Answer The Blockchain Need For RNG

There is a lot of advantages of blockchain technology but its transparency, combined with the deterministic nature of computers is a stumbling block in creating true on-chain randomness. Yet, random number generators (RNGs) are essential tools for solving various algorithmic problems. Here we will discuss the approach Oasis has adopted to ensure smart contract developers can integrate randomness into their applications in a hassle-free manner. What is RNG As deterministic machines, computers function by following predictable instructions. So, randomness is never truly possible. However, almost random numbers can be generated with external inputs or complex algorithms. But how feasible is this? Not very. For example, a deterministic RNG can only mimic randomness and produce pseudo-random outputs using algorithms transforming a starting “seed” value into sequences. If the “seed” is known, it all becomes predictable. On the other hand, non-deterministic RNG can generate completely random numbers by using erratic physical phenomena, like dice rolls or photon scattering, as a workaround for the computer reading predictable patterns. Why blockchains need RNG? When you try to replicate RNG in the smart contract framework, it gets interesting. Whether you are developing dApps for the web3 at large or the cryptoAI space, you will need provable fairness or unbiased and tamperproof outcomes based on unpredictable inputs. Even from a core blockchain point of view, RNG plays a crucial role in cryptographic operations. It produces the unique keys or values needed for securing transactions, encrypting data, or authenticating users, ensuring that outputs cannot be guessed or replicated. Without secure on-chain RNG, reverse engineering of keys, outcome manipulation and all kinds of exploits become possible. Now, blockchain technology also use deterministic rules, and all nodes reaching a consensus is a non-negotiable criteria. This makes on-chain randomness tricky but it is still doable. For example, verifiable random functions, commit-reveal schemes, or the method Oasis has adopted — using Verifiable Random Function (VRF) and some other cryptographic primitives. Let’s now take a closer look into Oasis. How Oasis RNG works? With its default focus on smart privacy and scalability, Oasis uses its confidential EVM runtime, Sapphire to streamline RNG through its randomBytes precompile. By abstracting a simple Solidity function, any smart contract developer can integrate randomness into their applications without dealing with the complexities of blockchain RNG. It basically works like this. Generating the Per-Block Root RNG Sapphire communicates with a key manager runtime to generate secret keys. The key manager supports multiple kinds of keys, some of which are long-term and some of which are ephemeral. The ephemeral keys are used for encrypting transactions and also the RNG. To improve security, these keys are never persisted anywhere and are rotated each epoch. This means fresh keys are generated, and after a while, old keys get securely erased and cannot be recovered even if any component is later compromised. The RNG exposed to Sapphire contracts is initialized on every block. Each block uses private ephemeral entropy obtained from the key manager runtime. Only remotely attested Sapphire instances can obtain this private entropy inside the TEE, which ensures that no external observers can learn anything about the RNG state. Next, this entropy is processed and used as a root VRF key. To turn this entropy into a usable key, Sapphire employs SHA-3-derived algorithms like TupleHash, KMAC256, and cSHAKE. These functions process the epoch-specific entropy from the key manager runtime, producing a unique per-block root RNG that anchors all subsequent randomness in the block with consistency and security. Domain Separation for Per-Transaction RNGs The per-block root RNG alone isn’t enough. Each transaction needs its own private RNG, which is where domain separation comes in. Sapphire builds on the key manager’s output by using Merlin transcripts to initialize per-transaction RNGs from the root RNG, customizing randomness for individual interactions using transaction-specific data. This customization is implemented in the Rust Runtime SDK used to build Sapphire, which handles the VRF and domain separation schemes. Together with the key manager’s private entropy, it ensures private, unbiased, and unpredictable outputs are exposed to developers via the randomBytes precompile. Code examples Basic Random Number Generation This snippet shows how to generate a 32-byte random value, ideal for straightforward RNG needs in a dApp like a poker game. bytes memory randomPad = Sapphire.randomBytes(32, ""); Random Number for Signing Key Pair This snippet uses randomBytes to seed a signing key pair generation, which you can use as a part of a more complex RNG-driven mechanism while ensuring cryptographic security.

The Database Zoo: Inside Time-Series Engines (InfluxDB, Prometheus, Timescale)

The Database Zoo: Inside Time-Series Engines (InfluxDB, Prometheus, Timescale)

Time-Series Databases (TSDBs) are purpose-built for continuous, high-volume, time-ordered data. They optimize writes with append-only layouts and time partitioning, speed queries via time-first indexing and compression-aware scans, and control storage with retention and downsampling. Engines like InfluxDB, TimescaleDB, Prometheus, and VictoriaMetrics embody these design choices differently. Use a TSDB when you need massive ingest, time-range analytics, and efficient storage—especially for monitoring, IoT, telemetry, and financial ticks—rather than stretching general-purpose SQL/NoSQL beyond their comfort zone.
