Sprout to Sapling Migration Tool
|
|
--------------------------------
|
|
This release includes the addition of a tool that will enable users to migrate
|
|
shielded funds from the Sprout pool to the Sapling pool while minimizing
|
|
information leakage.
|
|
|
|
The migration can be enabled using the RPC `z_setmigration` or by including
|
|
`-migration` in the `zcash.conf` file. Unless otherwise specified funds will be
|
|
migrated to the wallet's default Sapling address; it is also possible to set the
|
|
receiving Sapling address using the `-migrationdestaddress` option in `zcash.conf`.
|
|
|
|
See [ZIP308](https://github.com/zcash/zips/blob/master/zip-0308.rst) for full details.

Sprout to Sapling Migration Tool Fixes
|
|
--------------------------------------
|
|
The 2.0.5-1 release includes fixes to the Sprout to Sapling Migration Tool
|
|
found in testing. We resolved an issue which would cause the zcash daemon to
|
|
crash if calling the RPC `z_getmigrationstatus` while a wallet's migration
|
|
transactions are in the mempool.
|
|
|
|
New consensus rule: Reject blocks that violate turnstile
|
|
--------------------------------------------------------
|
|
In the 2.0.4 release the consensus rules were changed on testnet to enforce a
|
|
consensus rule which marks blocks as invalid if they would lead to a turnstile
|
|
violation in the Sprout or Shielded value pools.
|
|
**This release enforces the consensus rule change on mainnet**
|
|
|
|
The motivations and deployment details can be found in the accompanying
|
|
[ZIP draft](https://github.com/zcash/zips/pull/210) and
|
|
[PR 3968](https://github.com/zcash/zcash/pull/3968).
|
|
|
|
Developers can use a new experimental feature `-developersetpoolsizezero` to test
|
|
Sprout and Sapling turnstile violations. See [PR 3964](https://github.com/zcash/zcash/pull/3964) for more details.

|
64-bit ARMv8 support
|
|
--------------------
|
|
Added ARMv8 (AArch64) support. This enables users to build zcash on even more
|
|
devices.
|
|
|
|
For information on how to build see the [User Guide](https://zcash.readthedocs.io/en/latest/rtd_pages/user_guide.html#build)
|
|
|
|
Users on the Zcash forum have reported successes with both the Pine64 Rock64Pro
|
|
and Odroid C2 which contain 4GB and 2GB of RAM respectively.
|
|
|
|
Just released, the Odroid N2 looks like a great solution with 4GB of RAM. The
|
|
newly released Jetson Nano Developer Kit from Nvidia (also 4GB of RAM) is also
|
|
worth a look. The NanoPC-T3 Plus is another option but for the simplest/best
|
|
experience choose a board with 4GB of RAM. Just make sure before purchase that
|
|
the CPU supports the 64-bit ARMv8 architecture.
