保证金计算

关于保证金/担保金要求,在tezos官方文档中进行了解释:

保证金¶保​​证金的成本是 BLOCK_SECURITY_DEPOSIT=每个创建的区块512 XTZ, ENDORSEMENT_SECURITY_DEPOSIT=每个背书64 XTZ.每位代表 密钥具有关联的保证金帐户.当代表烘烤时 或背书块,保证金将自动移至 存款帐户在PRESERVED_CYCLES个周期后被冻结 它会自动移回到面包师的主要帐户. 由于存款的锁定时间为PRESERVED_CYCLES,因此可以 计算在任何给定时间,大约(((BLOCK_SECURITY_DEPOSIT + ENDORSEMENT_SECURITY_DEPOSIT * ENDORSERS_PER_BLOCK)* (PRESERVED_CYCLES +1)* BLOCKS_PER_CYCLE)/763e6=总数的8.25％ 代币应作为保证金存放.这也意味着 委托应拥有超过8.25％的委托代币数量 为了避免错过创建任何块的机会.

这是" 8.25％"数字的来源.但是,它假设主动进行的XTZ总数中的特定数量为763,000,000,这不是实际情况.

从某种意义上讲,您也可以将此数字解释为"整个网络"的保证金,但这并不能准确告诉您单个面包师的资本要求是什么.

可以在tzstats 此处上实时获得xtz的实际数量.

当前在313728高度的放样量为503,461,245.334 xtz.

使用该数字作为保证金所需的有效xtz百分比约为12.5％.

还要再注意一次,这个数字只是一个期望值,因为已实现的数字直接取决于面包师从一个周期到另一个周期分配的权利数量,并且该数量是随机波动的(随着卷数的增加,变化较小)但是),因此债券需求会相应地波动.

Regarding the security deposit/bond requirement, it is explained on the tezos official documentation:

Security deposits¶ The cost of a security deposit is BLOCK_SECURITY_DEPOSIT = 512 XTZ per block created and ENDORSEMENT_SECURITY_DEPOSIT = 64 XTZ per endorsement. Each delegate key has an associated security deposit account. When a delegate bakes or endorses a block the security deposit is automatically moved to the deposit account where it is frozen for PRESERVED_CYCLES cycles, after which it is automatically moved back to the baker’s main account. Since deposits are locked for a period of PRESERVED_CYCLES one can compute that at any given time, about ((BLOCK_SECURITY_DEPOSIT + ENDORSEMENT_SECURITY_DEPOSIT * ENDORSERS_PER_BLOCK) * (PRESERVED_CYCLES + 1) * BLOCKS_PER_CYCLE) / 763e6 = 8.25% of all tokens should be held as security deposits. It also means that a delegate should own over 8.25% of the amount of token delegated to them in order to not miss out on creating any block.

This is where the “8.25%” number comes from. However it assumes a specific number of the total XTZ actively staking to be 763,000,000 which is not the actual situation.

You can also interpret this number as the security deposit of “the entire network” in some sense however this does not tell you accurately what is the capital requirement for an individual baker.

The actual number of xtz staking can be obtained in real time on tzstats here.

Currently the amount staking at height 313728 is 503,461,245.334 xtz.

Using that number the effective percentage of xtz that is needed as security deposit is roughly 12.5%.

Note also one more time that this number is just an expectation because the realized number depends directly on the number of rights that a baker is allocated from cycle to cycle and that number fluctuates randomly (with less variance as the number of rolls grows though) so the bond requirement fluctuates accordingly.
