Currently, if -validatepegin is given, and block validation can't proceed because the parent chain is not synced, we mark the block invalid and put it in a queue to be "revalidated" later. Unfortunately, marking a block invalid has downstream consequences, in particular causing descendant blocks to be marked invalid, which are not currently fixed by the queue. Instead, we'll use a different strategy: if the mainchain daemon isn't sufficiently synced to validate a block, we will "stall" connecting that block to the chain, and have ActivateBestChain simply keep the tip at the previous block until we're ready. We can still download and validate (partly) blocks past this point while we're waiting. They will be connected once the parent chain daemon catches up. |

Elements Project blockchain platform
This is the integration and staging tree for the Elements blockchain platform, a collection of feature experiments and extensions to the Bitcoin protocol. This platform enables anyone to build their own businesses or networks pegged to Bitcoin as a sidechain or run as a standalone blockchain with arbitrary asset tokens.
Modes
Elements supports a few different pre-set chains for syncing. Note though some are intended for QA and debugging only:
- Liquid mode:
elementsd -chain=liquidv1(syncs with Liquid network) - Bitcoin mainnet mode:
elementsd -chain=main(not intended to be run for commerce) - Bitcoin testnet mode:
elementsd -chain=testnet3 - Bitcoin regtest mode:
elementsd -chain=regtest - Elements custom chains: Any other
-chain=argument. It has regtest-like default parameters that can be over-ridden by the user by a rich set of start-up options.
Confidential Assets
The latest feature in the Elements blockchain platform is Confidential Assets, the ability to issue multiple assets on a blockchain where asset identifiers and amounts are blinded yet auditable through the use of applied cryptography.
- Announcement of Confidential Assets
- Confidential Assets Whitepaper to be presented April 7th at Financial Cryptography 2017 in Malta
- Confidential Assets Tutorial
- Confidential Assets Demo
- Elements Code Tutorial covering blockchain configuration and how to use the main features.
Features of the Elements blockchain platform
Compared to Bitcoin itself, it adds the following features:
- Confidential Assets
- Confidential Transactions
- Federated Two-Way Peg
- Signed Blocks
- Additional opcodes
Previous elements that have been integrated into Bitcoin:
- Segregated Witness
- Relative Lock Time
Elements deferred for additional research and standardization:
