Limits

The following are the current limits enforced in the miden-base and miden-node:

Accounts

• Max assets per account: no limit.
• Max top-level storage slots per account: 255. Each storage slot can contain an unlimited amount of data (e.g., if the storage slot contains an array or a map).
• Max code size per account: no limit (but we plan to enforce code size limit in the future, at least for public accounts).

Notes

• Min assets per note: 0.
• Max assets per note: 255.
• Max inputs per note: 128. The value can be represented using as a single byte while being evenly divisible by 8.
• Max code size per note: no limit (but we plan to enforce code size limit in the future, at least for public notes).

Transactions

• Max input notes per transaction: 1024.
• Max output notes per transaction: 1024.
• Max code size of tx script: no limit (but we plan to enforce code size limit in the future).
• Max number of VM cycles: \(2^{30}\).

Batches

• Max number of input notes: 1024.
• Max number of output notes: 1024.
• Max number of accounts: 1024.
• Max number of VM cycles: \(2^{30}\).

Blocks

• Max batches per block: 64.
• Max number of accounts: 65536 (max accounts per batch × max number of batches).
• Max number of input notes: 65536 (max notes per batch × max number of batches).
• Max number of output notes: 65536 (max notes per batch × max number of batches).
• Max public data size (for both notes and accounts): no limit.
