Writes about the rules around crypto: what a regulator's decision says, what it does not say, and which of the two the market reacted to.
The 18 September changelog records Transaction V1, a rent cut to 5,080 lamports per byte and a slot-time reduction to 250ms as notable mainnet feature gates, with SIMD debate on removing block compute limits.
The Polkadot parachain would replace a developer multisig with pallet-referenda and conviction voting on just two tracks, then remove Sudo through the first real referendum.
A Polkadot forum post introduces JamScript, a language and SDK meant to let developers build JAM applications without understanding JAM's internals. It is a proposal and a discussion, not a shipped platform.
The change guards an assertion in the silent-payments reference code so it only runs when the optional expected value is present, instead of dereferencing a None.
A draft opcode would create contracts that live only for the duration of a single transaction; the latest update clarifies ephemeral-account semantics and fixes its EIP references.
A 21 September post-effective amendment on Form POS AM refreshes disclosures for Bitwise's XRP ETF trust and registers zero new shares — a maintenance filing, not an SEC green light or a launch.
cardano-node 11.1.2 optimises memory in time lock scripts. The release notes keep two known regressions against 11.0.1 in view rather than claiming the problem is closed.
The meta EIP for the next Ethereum upgrade was rewritten on 21 September with the decisions from All Core Devs Consensus 187: four proposals declined, one promoted, one added.
SIMD-0596 raises the account lock limit for version 1 transactions by half. It is a Draft, it does not touch legacy or v0 transactions, and the feature key is still blank.
The FCA has published perimeter guidance on which activities need authorisation, thirteen months before the regime bites — and will consult again in October on changes the Government has already made to the law.
