This fuzz target takes its seeds in a simple and well-defined format: a four-byte LE budget, then a transaction, Simplicity program and witness, each prefixed by a four-byte LE length. The fuzz target extracts any additional randomness it needs from the txid of the first input of the transaction, since this data is not interpreted in any other way we therefore won't confuse the fuzzer. The reason for this design, rather than a more typical "just query the fuzzer when you need stuff", is to make it possible to fairly easily generate test vectors from sources other than this fuzz test. (For example, I have an alternate target which uses Rust code to generate well-formed Simplicity programs, which quickly gets high coverage at the expense of being an unmaintainable mess.) This commit includes a .c file with a small function to comute the AMR of a program. This is needed to pass a correct AMR to the Simplicity interpreter, to exercise all the AMR-checking paths. In practice this is not really necessary; Elements passes NULL to disable these AMR checks. |

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:
Additional RPC commands and parameters:
The CI (Continuous Integration) systems make sure that every pull request is built for Windows, Linux, and macOS, and that unit/sanity tests are run automatically.

What is the Elements Project?
Elements is an open source, sidechain-capable blockchain platform. It also allows experiments to more rapidly bring technical innovation to the Bitcoin ecosystem.
