Subject: Re: [bitcoin-dev] Fwd: Proposal of a new BIP : annual splitting
	blockchain database to reduce its size.
Precedence: list

=20
but also *what specifically* to do, and *how* to do it. This concept=20
(historically known as "flip the chain" and/or "UTXO commitments") is not n=
ew,=20
merely complicated to design and implement.
