Privateness coin Zcash has efficiently laborious forked within the deliberate community replace “Heartwood.” With the replace, miners can obtain coinbase transactions proper to a non-public deal with, along with different new options.
The laborious fork occurred on July 16 at 10:58 UTC at block peak 903,000, in response to the Electrical Coin Firm (ECC), the for-profit growth home behind the venture. An uncontentious laborious fork, Heartwood was supported by each the ECC and Zcash Basis.

The replace contains two Zcash Enchancment Proposals (ZIPs). The primary, “Shielded Coinbase” (ZIP 213) brings long-sought privateness options for Zcash (ZEC) mining whereas ZIP 221 “Flyclient” provides help for light-weight shoppers that confirm transactions, the ECC stated in a March weblog.
As a tough fork, the updates are backward incompatible, that means all nodes should sync to the brand new software program as a way to use the Zcash blockchain.
Heartwood is the privateness coin’s fourth laborious fork for the reason that community launched in late 2016. Zcash final laborious forked in December 2019 with “Blossom.”
“The Zcash Basis is worked up to help the Heartwood Zcash improve alongside the ECC, and thrilled that customers will quickly be capable to hook up with the Zcash community utilizing Zebra, an alternate, consensus-compatible Zcash implementation constructed by the Basis,” Zcash Basis govt director Josh Cincinnati stated in an e-mail to CoinDesk.
(The Zebra consumer, written in Rust, was inbuilt cooperation with Parity Applied sciences and launched in June 2019).
Non-public coinbase transactions
Shielded coinbase transactions permit miners to assert coinbase transactions – the reward for processing transactions – on to Zcash’s shielded addresses. Shielded addresses obfuscate data reminiscent of quantities, addresses and the encrypted memo area.
Implementing non-public coinbase transactions has been on the Zcash roadmap for the reason that venture’s early days. It was made doable by earlier technical updates present in 2018’s Sapling laborious fork, in response to the ECC.
“With this function, when a mining pool or solo miner chooses to maneuver coinbase rewards, [its] now non-public. For instance, a mining pool can carry out shielded payouts to miners in a shielded transaction,” ECC CTO Nathan Wilcox stated in an e-mail to CoinDesk.
Flyclient
Flyclient permits customers to confirm transactions with the smallest quantity of knowledge doable. Just like Bitcoin Simplified Cost Verification (SPV) nodes, the spec proves the data of a transaction utilizing solely the block header, slightly than the total content material of the block.
The ZIP has a couple of optimistic penalties for builders: It offers simpler entry to cross-chain interoperability, reminiscent of with the Ethereum community, and gives safety for gentle shoppers. The ECC introduced plans to construct interoperability initiatives with the second-largest blockchain by market cap, Ethereum, at DevCon 5 this previous October.

“Proper now, you want a Zcash full node to get full privateness. Our ZIP helps defend gentle shoppers from malicious servers and pushes in direction of full privateness for each pockets,” stated ZIP co-author and Summa founder James Prestwich in a non-public message.
