Compact Block support (BIP 152)
The primary goal is reducing the bandwidth spikes at relay time, though in many cases it also reduces propagation delay. It is automatically enabled between compatible peers. BIP 152
As a side-effect, ordinary non-mining nodes will download and upload blocks faster if those blocks were produced by miners using similar transaction filtering policies. This means that a miner who produces a block with many transactions discouraged by your node will be relayed slower than one with only transactions already in your memory pool. The overall effect of such relay differences on the network may result in blocks which include widely- discouraged transactions losing a stale block race, and therefore miners may wish to configure their node to take common relay policies into consideration.
Hierarchical Deterministic Key Generation
Newly created wallets will use hierarchical deterministic key generation according to BIP32 (keypath m/0’/0’/k’). Existing wallets will still use traditional key generation.
Backups of HD wallets, regardless of when they have been created, can therefore be used to re-generate all possible private keys, even the ones which haven’t already been generated during the time of the backup. Attention: Encrypting the wallet will create a new seed which requires a new backup!
Wallet dumps (created using the
dumpwallet RPC) will contain the deterministic seed. This is expected to allow future versions to import the seed and all associated funds, but this is not yet implemented.
