Work towards #589. The VM PR FuelLabs/fuel-vm#780 contains a working implementation. To allow contracts larger than the contract size limit, and to allow upgradability, we'll be adding a new tx type that's just a bunch of bytes, and opcodes to load subsections of that. A *blob* will be like a contract, but without state or balances, allowing it to be quite a bit cheaper. The new instructions `BSIZ` and `BLDD` and the new blob mode for `LDC` closely follow how `CSIZ`, `LDC` and `CCP` work, but only operation on blob data. ### Before requesting review - [x] I have reviewed the code myself

Work towards FuelLabs/fuel-specs#589. Spec PR FuelLabs/fuel-specs#592. Adds support for Blob transactions, which are inserted into the onchain database column called `Blobs`. Also updates fuel-vm to 0.56.0, which introduces the new tx type. Work-in-progress, still needs: - [x] Regenesis support - [x] Tests ## Checklist - [x] Breaking changes are clearly marked as such in the PR description and changelog - [x] New behavior is reflected in tests ### Before requesting review - [x] I have reviewed the code myself - [x] I have created follow-up issues caused by this PR and linked them here ### After merging, notify other teams - [ ] [Rust SDK](https://github.com/FuelLabs/fuels-rs/) - [ ] [Sway compiler](https://github.com/FuelLabs/sway/) - [ ] [Platform documentation](https://github.com/FuelLabs/devrel-requests/issues/new?assignees=&labels=new+request&projects=&template=NEW-REQUEST.yml&title=%5BRequest%5D%3A+) (for out-of-organization contributors, the person merging the PR will do this) --------- Co-authored-by: Ahmed Sagdati <37515857+segfault-magnet@users.noreply.github.com> Co-authored-by: segfault-magnet <ahmed.sagdati.ets@gmail.com>

Tracking issue for
Blobtransactions and related opcodes.As discussed with the client team on 2024-06-20, to allow contracts larger than the contract size limit, and to allow upgradability, we'll be adding a new tx type that's just a bunch of bytes, and opcodes to load subsections of that. The whole thing reminds contracts and
LDCa bit, but blob won't have state or balances, and the corresponding load instructions will be slightly different.Implemented in:
