Key terms

5th Bitcoin halving (~April 2028): Block 1,050,000. Block reward drops from 3.125 BTC to 1.5625 BTC. Daily issuance falls from ~450 BTC to ~225 BTC. Circulating supply will be ~19.95-19.97M BTC after.
Glamsterdam (2026): Next planned Ethereum upgrade after Fusaka (Dec 2025). Continues The Surge agenda — additional L2 throughput, blob expansion, execution-layer optimizations.
Hegota (H2 2026): Ethereum upgrade slated for second half of 2026. Targets state bloat and storage inefficiencies. Verkle Trees a leading candidate. Goal: reduce node storage burden up to 90%.
BIP-119 (OP_CTV): CheckTemplateVerify proposal by Jeremy Rubin. Most mature Bitcoin covenant proposal. Last updated April 2026. Activation contested; no consensus yet.
BIP-345 (OP_VAULT): James O'Beirne proposal. Adds OP_VAULT and OP_VAULT_RECOVER tapscript opcodes. Builds on CTV. Enables vault-style safety mechanisms with recovery paths.
DAC8: EU Directive on Administrative Cooperation #8. In force January 1, 2026. CASPs report EU-resident crypto transactions. First inter-state exchange deadline September 30, 2027.
IRS Form 1099-DA: New US crypto broker reporting form. Cost-basis reporting required from January 1, 2026. Transition relief through December 31, 2026 (IRS Notice 2026-20). Full enforcement 2027.
MiCA grandfathering deadline: July 1, 2026. Absolute EU-wide deadline for CASPs to obtain MiCA authorization (or have applied). Member-state grandfathering periods vary 5-18 months.
EU Digital Euro: ECB closed preparation phase October 2025. Pilot exercise mid-2027 (if regulation passes 2026). Potential first issuance 2029. Final issuance decision pending legislation.
NIST PQC standards: Finalized August 2024. FIPS 203 (ML-KEM, key encapsulation), FIPS 204 (ML-DSA, signatures), FIPS 205 (SLH-DSA, hash-based signatures). Required for post-quantum migration.
Ethereum post-quantum roadmap: Vitalik Buterin published February 2026. Targets BLS signatures, KZG data availability, ECDSA accounts, ZK proofs. Four-year Strawmap with ~7 hard forks every 6 months.
BIP-360 (Bitcoin PQC): Bitcoin post-quantum proposal. Adds quantum-safe address types for voluntary migration. No coordinated funding; mainnet tooling targeted Q2 2026 by BTQ.
