Which Countries and Cities Lead in the Number of Bitcoin Nodes?
A Bitcoin node is a cornerstone of the world's first cryptocurrency, operating round-the-clock in complete harmony within the network of its own kin. Its purpose is to validate transactions and uphold the network's decentralization. With 45,000 nodes within the Bitcoin network, an exploration into their geographical dispersion makes for an intriguing analysis. Crypto in Space: Blockchain Technologies Touching the Stars
Blockchain technologies and digital assets are steadily infiltrating the cosmic realm. Cryptocurrencies are being deployed in the construction and launch of satellites, the creation of blockchain nodes, and even in the hunt for space-bound crypto treasures. 
On October 14, 2025, at 11:00 CEST, Chiliz activates the Snake8 hard fork. The upgrade replaces equal‑share block production with a lottery‑like draw weighted by stake that enforces a minimum selection frequency to keep smaller validators in rotation. Nodes that don’t upgrade will stop producing blocks. Polygon experiences finalization outage due to node bug
On Sept. 10, the Polygon blockchain ran into transaction finalization issues due to a bug in the Bor and Erigon software clients used to run nodes. The incident affected certain RPC services and validator synchronization, but the network never stopped and continued producing blocks. Top Web3 Data Availability Networks in 2024
Blockchain functionality greatly depends on how participants access data about the requests, network state and other details to verify transactions. Since data needs to be shared across all nodes, delays in propagation can impact network capacity and slow down transactions. To prevent this, data availability (DA) networks offer a solution. 
IOST Coin: Empowering the Internet of Services!
IOST is reshaping IoS with unparalleled speed and scalability. Its innovative Proof-of-Believability mechanism, 400+ nodes worldwide, and ability to process 8000 transactions per second stand as a testament to IOST's transformative potential for online services. 
Deploying a Shardeum Testnet Node to Get an Airdrop
Shardeum is an EVM-based, linearly scalable network, allowing for the deployment of smart contracts. The project utilizes dynamic sharding technology, ensuring appropriate decentralization and efficient scalability with an increase in the number of nodes. Vitalik's Blog Unveils Ethereum Verification Solutions
Ethereum, the decentralized smart contracting platform behind DeFi and NFTs, is currently facing an issue with transaction verification. In a recent blog post, Ethereum co-founder Vitalik Buterin acknowledged that verifying transactions on the mainnet is challenging, causing difficulty for users to run their own nodes and instead rely on third-party services. Cardano Revolutionizes Blockchain with Dynamic P2P Network!
Dynamic P2P automates the process of selecting peer nodes, improving the connection between distributed nodes and simplifying the process of launching a relay or block-producing node. This eliminates the need for static configurations and manual data entry by stake pool operators (SPO).
