Bitcoin explained: supply, transactions, mining and custody risks

-

Bitcoin is a peer-to-peer electronic cash system recorded on a public blockchain. Transactions spend outputs controlled by cryptographic keys, while proof-of-work mining orders transactions into blocks and helps nodes converge on a valid chain.

The protocol limits issuance according to predefined rules, but scarcity does not guarantee a market price. Bitcoin transactions are generally irreversible after confirmation, and control of private keys is essential.

Risks include volatility, loss or theft of keys, malicious wallet software, exchange failure, fee spikes, address mistakes and changing legal or tax treatment. Network consensus does not insure users against those losses.

Ethereum's 2026 roadmap: shipped upgrades versus future plans

-
Ethereum's roadmap changed substantially between 2024 and 2026. Dencun activated in March 2024, Pectra followed in May 2025, and Fusaka activated in December 2025. The next named upgrade is Glamsterdam—but users should distinguish completed upgrades from proposals and estimated dates. What has already happened Dencun introduced blob transactions that reduced the cost of posting rollup data. Pectra included changes such as EIP-7702, which allows externally owned accounts to delegate functionality to smart-contract code. Fusaka added further scaling and data-availability improvements. These are historical activations, not future promises. Their practical effects still depend on wallets, applications, network demand and how developers implement the new capabilities. What is planned next Ethereum.org identifies Glamsterdam as the next named upgrade. Block-level Access Lists and enshrined proposer-builder separation have been described as headline items, with an expected activation...

UK crypto regulation: what changes in October 2027

-
The United Kingdom created a broader cryptoasset regulatory framework in 2026, but the main new authorisation regime is not yet fully in force. HM Treasury says the Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2026 will take effect in October 2027. That timing matters. A company saying it is “registered in the UK” today should not automatically be described as already authorised under the future regime. What the 2026 Regulations establish The Regulations bring specified cryptoasset activities into the UK's regulated-activities framework. When the relevant provisions commence, firms carrying on those activities will generally need authorisation from the Financial Conduct Authority (FCA), unless an exclusion or another applicable status applies. HM Treasury's April 2026 policy note says the framework was made in February 2026 and comes into force in October 2027. The government also proposed amendments dealing with stablecoin payment services and other t...

What the SEC's 2026 crypto interpretation actually says

-
On 17 March 2026, the US Securities and Exchange Commission issued an interpretation explaining how federal securities laws apply to several types of crypto assets and transactions. The Commodity Futures Trading Commission joined the interpretation with guidance on how its staff would administer the Commodity Exchange Act consistently with it. The headline is important but easy to oversimplify: the SEC said most crypto assets are not themselves securities. That does not mean every sale, distribution, staking service or investment arrangement involving a token falls outside securities law. What the interpretation covers The interpretation provides a taxonomy covering digital commodities, digital collectibles, digital tools, stablecoins and digital securities. It also addresses protocol mining, protocol staking, airdrops and the wrapping of non-security crypto assets. A central distinction is between an asset and the transaction or arrangement through which it is offered. A non-secur...
