Proof of Stake Bitcoin Sidechains
Proof of stake is another consensus protocol that has been used on multiple block chains for quite some time now, there was a proposal on the Bitcoin-dev mailing list to attach proof of stake sidechains to the original Bitcoin blockchain. This allows for the development of decentralized networks which aim to manage reserves of Bitcoin, using custom application code and smart contracts that use Bitcoin as the native currency.

This release includes many improvements and bug fixes, and we recommend that users upgrade.

Verifying signatures

You will need gpg and our release signing key 7A73FE77DE2C4027. Note that you can get it: - from our website: https://acinq.co/pgp/drouinf.asc - from github user @sstone, a committer on eclair: https://api.github.com/users/sstone/gpg_keys

To import our signing key:

$ gpg --import drouinf.asc

To verify the release file checksums and signatures:

$ gpg -d SHA256SUMS.asc > SHA256SUMS.stripped
$ sha256sum -c SHA256SUMS.stripped
