Russia will extend its regional crypto mining ban to Moscow, the Moscow Region and parts of Kursk Region from Aug. 15, 2026. Summary August 15 restrictions cover Moscow, Moscow Region and nine designated territories within Russia’s Kursk Region. Resolution 936 bars cryptocurrency mining and mining-pool participation through December 31, 2032, citing grid risks. Mining demand already totals one gigawatt in Moscow’s power system, according to regional energy officials. The prohibition will remain in force through Dec. 31, 2032, under Government Resolution No. 936. Prime Minister Mikhail Mishustin signed the measure on July 25. The government published it on the official…
Bitcoin mining difficulty has dropped 19.9% from its peak in the third deepest ASIC era decline on record, as miners sell bitcoin at record rates and redirect power capacity toward artificial intelligence data centers. Summary Bitcoin mining difficulty has fallen 19.9% from its November 2025 peak of approximately 156 trillion to 126.23 trillion, the third deepest decline since dedicated ASIC hardware replaced graphics processors. Network hashrate declined roughly 12% from its late 2025 peak above one zettahash per second to approximately 868 exahashes per second by late July 2026, with Bitcoin Magazine Pro tracking 287 consecutive days of downward trend.…
The United States has sanctioned Iranian exchanges, frozen nearly $1 billion in cryptocurrency, and traced $3.84 billion in Iran-linked flows through a single offshore exchange, exposing the scale of sanctions evasion through digital assets.

Proof of work is a consensus mechanism that forces computers to spend measurable energy solving a mathematical puzzle before they can add a new block of transactions to a blockchain. It is the reason bitcoin has value as a settlement network and the reason that network consumes more electricity than some countries. Summary Proof of work requires miners to find a hash output below a target threshold by repeatedly guessing a nonce value, consuming real computational energy in the process. Bitcoin adjusts its mining difficulty every 2,016 blocks, roughly every two weeks, to maintain an average block time of 10…
A zero-knowledge proof lets one party prove to another that a statement is true without revealing any information beyond the truth of the statement itself. It is the cryptographic technique behind blockchain privacy, scalable rollups, and a growing number of identity verification systems. Summary Zero-knowledge proofs allow a prover to convince a verifier that a computation was performed correctly without revealing the underlying data, enabling both privacy and scalability on blockchains. The two main families of zero-knowledge proofs used in blockchain are zk-SNARKs, which require an initial trusted setup ceremony, and zk-STARKs, which do not require trusted setup but produce…
A testnet is a separate blockchain network that mirrors a production chain’s rules and functionality but uses tokens with no monetary value. It is where developers break things, test upgrades, and discover bugs before those bugs can cost anyone real money. Summary A testnet is a blockchain network that runs the same software as a mainnet but uses valueless tokens, allowing developers to test smart contracts, protocol upgrades, and applications without financial risk. Ethereum has run multiple testnets over its history, with Sepolia and Holesky serving as the primary public testing environments as of 2026 after the deprecation of Goerli.…
A mainnet is the production version of a blockchain network where transactions carry real economic value and are permanently recorded. When a cryptocurrency project launches its mainnet, it moves from concept to reality, and every line of code becomes a financial commitment. Summary A mainnet is a fully operational blockchain network where tokens have real market value, transactions are irreversible, and the consensus mechanism secures actual economic activity. Mainnet launches are milestone events that typically follow months or years of testnet development, security audits, and community governance processes. Hard forks and protocol upgrades on a mainnet are high stakes operations…
