dcrd v1.0.7

This release of dcrd primarily contains improvements to the infrastructure and other quality assurance changes that are bringing us closer to providing full support for Lightning Network.

A lot of work required for Lightning Network support went into getting the required code merged into the upstream project, btcd, which now fully supports it. These changes also must be synced and integrated with dcrd as well and therefore many of the changes in this release are related to that process.

Notable Changes

Dust check removed from stake transactions

The standard policy for regular transactions is to reject any transactions that have outputs so small that they cost more to the network than their value. This behavior is desirable for regular transactions, however it was also being applied to vote and revocation transactions which could lead to a situation where stake pools with low fees could result in votes and revocations having difficulty being mined.

This check has been changed to only apply to regular transactions now in order to prevent any issues. Stake transactions have several other checks that make this one unnecessary for them.

New feefilter peer-to-peer message

A new optional peer-to-peer message named feefilter has been added that allows peers to inform others about the minimum transaction fee rate they are willing to accept. This will enable peers to avoid notifying others about transactions they will not accept anyways and therefore can result in a significant bandwidth savings.

Bloom filter service bit enforcement

Peers that are configured to disable bloom filter support will now disconnect remote peers that send bloom filter related commands rather than simply ignoring them. This allows any light clients that do not observe the service bit to potentially find another peer that provides the service. Additionally, remote peers that have negotiated a high enough protocol version to observe the service bit and still send bloom filter related commands anyways will now be banned.
