Account model
EcDSA signature algorithm

The Babylon project designs security protocols that scale Bitcoin to secure the decentralized world. To this end, Babylon utilizes three primary facets of Bitcoin:

Bitcoin, the asset
Bitcoin, the PoW-secured timestamping server
Bitcoin, the censorship-resistant blockspace

Through inventing pioneering protocols, Babylon envisions a more secure and Bitcoin-centric decentralized world.

Units

Baby is divisible by 10^-6 and the base unit is a ubbn:

1 Baby = 1,000,000 ubbn
1 ubbn = 0.000001 Baby

Baby balances can be in either integer or string format. However, BitGo recommends using string format to ensure values don't exceed the programmable number limit.

Tokens

The Babylon blockchain doesn't natively support tokens.

Fees

Baby has the following fees:

Minimum fee = 0.007 Baby
Default fee rate = 0.007 Baby

Address Format

Babylon addresses follow the format: bbn1<38-character-bech32-body>. All addresses are exactly 42 characters in length and begin with the fixed prefix bbn1. This format adheres to the following regular expression:

1
/^(bbn)1(['qpzry9x8gf2tvdw0s3jn54khce6mua7l]{38})$/

Memo ID Support

Optionally, a ?memoId=<n> query parameter can be appended to the address for use cases such as identifying transaction metadata. Here, <n> can be any integer.
Using memoId-based addressing eliminates the need to generate multiple deposit addresses per user. A single static address can be reused safely across users and use cases, with the memoId serving as the unique identifier.
Since Babylon uses memoId-based receive addresses, manual consolidation is not required.
