\"The Electric Coin Company (ECC) says it discovered a new way to scale blockchains with "recursive proof composition," a proof to verify the entirety of a blockchain in one function. For the ECC and zcash, the new project, Halo, may hold the key to privacy at scale.\
\
A privacy coin based on zero-knowledge proofs, referred to as zk-SNARKs, zcash's current underlying protocol relies on "trusted setups." These mathematical parameters were used twice in zcash's short history: upon its launch in 2016 and first large protocol change, Sapling, in 2018.\
\
Zcash masks transations through zk-SNARKs but the creation of initial parameters remains an issue. By not destroying a transaction's mathematical foundation -- the trusted setup -- the holder can produce forged zcash.\
\
Moreover, the elaborate 'ceremonies' the zcash community undergoes to create the trusted setups are expensive and a weak point for the entire system. The reliance on trusted setups with zk-SNARKs was well known even before zcash's debut in 2016. While other research failed to close the gap, recursive proofs make trusted setups a thing of the past, the ECC claims.\"\
