# 0.20 Change Summary

> Balanced Exchange Framework (BEF) - Framework Version 1.0, 2026-08-22.
> Source of record: https://balancedexchangeframe.work/doc/v0-20

• Established LANA as the reference implementation of a shared BEF Balanced Split Architecture rather than the only coin with Split mechanics.

• Made coin-specific Registrar and Split architecture mandatory for every external Native Coin before ACTIVE status.

• Defined the common development path NATIVE COIN -> REGISTRATION -> REGISTERED COIN -> USE/CIRCULATION -> ACTIVE SUPPLY CHANGE & RECIRCULATION -> SPLIT -> NEXT BALANCED CYCLE.

• Added coin-specific Total Registered Supply, Active Coin Supply, sequential Coin Splits, Split Event history and a mandatory versioned Coin Split Profile.

• Clarified shared invariants versus coin-specific parameters: all ACTIVE coins follow Splits, but LANA Price(n+1) = Price(n) x 2 does not automatically apply to BTC, ETH or other coins.

• Added REGISTRY READY and SPLIT READY activation stages, so technical eligibility alone can never make a coin operational inside BEF.

• Strengthened COIN x PRODUCT x JURISDICTION: a functioning Registrar and Split Profile are required economic architecture, but do not replace coin-specific legal classification.

• Expanded Conditions Precedent to CP-57 with a dedicated Coin Split Activation Pack and updated Annex O/P and EU/UK/U.S. activation matrices accordingly.

• Superseded the 0.19 position that external coins did not inherit Split architecture: they now inherit the BEF Split concept and lifecycle, while retaining their own coin-specific numerical and economic rules.
